What does component input mean on a TV? LCD TVs: selecting roses - what can be connected? Purpose of TV sockets
We take digital sound from the optical output of the TV and feed it to the music tulips. center comraddm write on the 8th week, 2016
USB cable 120cm
Optical cable 1M long
The ends are covered with humic dry bags.
We use standard SPDIF with beveled corners.
Many of you, like me, have sometimes watched televisions and other computers, but have never been victorious, so it will be easy to find out what kind of animal it is.
There is an optical fiber in the middle, so light is supplied to one end - it can be removed from the other end.
And, you see, the converter itself is a metal box with connectors on both sides.
Enter from one side: life and digital sound, either through an optical Toslink cable like we have, or through a coaxial one.
On the other side: under 3.5mm headphones, two RCA tulips and a life indicator, a red one and a few cores.
The dimensions of the converter are small: 5.5cm*6cm*2cm
Ale vin dosit important zavdyaki metal body: 82g
The converter is easy to disassemble, just unscrew the screw.
And then two more and you’re ready:
At the back, bits and pieces were sloppily chopped up, the soldering in parts was not perfect, and the parts were not fluxed.
I'll give you close-up photos:

Well, let's connect.
Connection is incredibly simple, insert the required parts wherever required and power the USB port of the TV itself.
The indicator is bright, direct and light.
It’s better to turn it somewhere near the wall or seal it completely, since if it gets wet, then it won’t get stuck.
In the TV settings, in the sound section, you can select where to output the sound; on Samsung, it is best to go there through the soft settings button.
If the audio output is selected as in the screenshot, then the sound from the TV will no longer be heard, and when you try to adjust the volume, you will write about those that we have adjusted to the current speakers and now have to adjust the sound with the remote control from them.
You can not switch the sound to the external ones, they still play like they were built in, then you can play both the external and internal speakers at the same time, and in many cases the moon is in an hour of converting digital to analogue, so and the effect of the hall.
You can mute the selected speakers or change their volume to zero, so that the muted speaker icon does not jump to the side.
Also, when watching multi-channel films, it is better to use both speakers and other speakers, the TV transmits mid-frequencies better - language, music. the center acts as a sub and gives special effects.
When working, the converter does not heat up much.
I don’t have a professional microphone, so I did everything I could to use a basic camcorder to convey to you the difference in the sound of the original speakers and the external ones.
In reality there is a difference in other things, as in the video.
You will need bass headphones or speakers to make a difference, in laptop speakers or desktop plastic tweeters, you are unlikely to separate anything.
That's all, I thank everyone for your respect.
Glossary of terms
AV-in
Availability of the TV to the AV input.
The AV interface consists of a composite video interface and an audio interface. Using an AV input is the easiest way to connect a DVD player or VCR to your TV.
The composite interface is dedicated to transmitting video signals. The signal is transmitted through a single coaxial cable, for connection it is necessary to use an RCA type connector (tulip). In the era of VHS, this method of transmitting video was unified, and with the advent of DVD, new ways of connecting video devices to a TV appeared that would provide higher image luminosity.
The advancement of the composite video interface includes those that almost all televisions are equipped with it. The main shortcoming lies in the fact that it slightly “coarsens” the images, collecting other details. This interface is not suitable for transmitting high-level signals.
AV input on the front or side panel
The TV has an AV input on the front or side panel.
The AV input is connected to the audio interface and the composite video interface and is used to connect an external video device to the TV ( div. "AV-in").
Rearranging the input interfaces on the front or back panels significantly improves access to them. This kind of adjustment can be done manually in these situations, if you need to quickly connect an external video signal to the TV (for example, a video camera to watch a filmed video). The distribution of physical interfaces is much more complex.
AV output
The TV has an AV output.
The AV interface is a combination of a composite video interface and an audio interface ( div. "AV-in").
The AV output can be used to record TV programs on an external DVD recorder or VCR.
Bluetooth
Availability of Bluetooth droneless data transmission interface.
Using Bluetooth, you can connect your phone to your TV and view your recorded photos on the big screen. In addition, wireless headphones can be connected to the TV via Bluetooth.
Support for the DVB-C standard.
DVB-C (Digital Video Broadcasting-Cable) is a European standard for digital cable television. Digital video transfers the video signal to digital video. Instead of an analogue TV station (PAL, SECAM, NTSC), the digital video signal is transmitted without interference and with minimal waste, so the clarity of the image and sound when using a digital signal is significant. To compress the DVB-C stream, the MPEG-2 or MPEG-4 codec is used.
The TV supports the DVB-S standard.
DVB-S is a standard for digital satellite television.
By connecting a satellite dish with a decoder to a TV with DVB-S support, you can watch digital satellite channels without an additional receiver.
div. "CI/PCMCIA support").
The TV supports the DVB-S2 standard.
DVB-S2 is a standard for digital satellite television, adopted in 2005. DVB-S2 is a continuation of the DVB-S standard. The new standard is enhanced by increased capacity of the communication channel. In addition, it is possible to introduce new types of signal modulation. DVB-S2 receivers can receive both DVB-S2 and DVB-S signals.
By connecting a satellite dish with a decoder to a TV with DVB-S2 support, you can watch digital satellite channels without an additional receiver.
To view encrypted channels, you need a smart access module ( div. "CI/PCMCIA support").
Support for the DVB-T standard.
DVB (Digital Video Broadcasting) is a family of digital television standards. DVB-T is a standard for terrestrial broadcasting. The data is transmitted using the MPEG2 and MPEG4 compression standards. Communication in DVB-T is carried out in an experimental mode in several regions of Russia, but the standard is gradually increasing in scope.
Support for the DVB-T2 standard.
DVB (Digital Video Broadcasting) is a family of digital television standards. DVB-T is a standard for terrestrial broadcasting.
DVB-T2 is a further development of the DVB-T standard. Similar to the previous modification, DVB-T2 has a 30% increase in throughput, which is especially important when working with HD channels. In addition, DVB-T2 will provide a stronger signal for mobile broadcasters.
FM radio
The presence of a built-in FM tuner. When you wake up, the tuner turns your TV into a radio, adding additional basic functions.
HD format
Maximum image separation that can be created by an HDTV TV.
HDTV (High Definition Television) is a new TV standard that uses high-quality digital signal and high-quality digital signal to ensure the highest picture clarity.
HDTV vikorist widescreen images on both sides 16:9 and on separate sides 1920x1080 (1080i/p) or 1280x720 (720p). The letter "i" at the end means the alternate row mode, in which one new frame is displayed twice: in the first pass, unpaired rows are displayed, and in the other, paired rows are displayed. The letter "p" at the end means progressive image display mode. In addition to the alternate row mode, in the progressive mode all rows (paired and unpaired) are displayed in one pass.
The 1080p mode provides the most vivid picture quality from all available high-definition TV video modes.
LED backlighting
RK TVs use light-emitting diode (LED) lighting instead of standard cold cathode fluorescent lamps (CCFL).
Light-emitting diode illumination allows you to increase the color color (RGB-LED technology), change the thickness of the screen (Edge-LED technology), and reduce energy consumption.
Due to the short price of LED lighting, you can determine the price.
The TV supports the NTSC standard.
The color television communication system has been fragmented by the USA. Vikorist is practiced in Old America, Japan and other countries of Old Africa. The main drawback of the system is the possibility of interference with color transfer. To change these conditions, NTSC TVs are equipped with color tone controls. If you want to watch video networks in NTSC format (for example, with friends from the USA), your TV must comply with this standard.
The TV supports the PAL standard.
PAL is one of the television communication standards. The PAL system is an improved version of the NTSC system ( div. "NTSC"). The advantage of this standard is greater stability of information about the color and less sensitivity to confusion. Television communication with this system is carried out in most countries of Western Europe, in Australia and a number of countries in Asia and Africa. The presence of this system on a TV is important when watching recordings on video cassettes and video disks, as well as when receiving satellite channels.
SECAM TV support.
Standard television signal received on the territory of our region. In 1967, the system began to operate regularly in the USSR and France. Currently, the SECAM standard is also adopted in many other countries of Europe, Asia and Africa. The SECAM system will provide twice as little as NTSC ( div. "NTSC"), vertical clarity of the color image.
TV tuner (analog)
Availability of a primary (analog) TV tuner.
All modern TVs are equipped with such tuners and can receive broadcast programs. This parameter may not be relevant for plasma panels and projection televisions. The sounds can be generated either with or without a tuner. In some models without a tuner, RK TVs can be supplied. If you are planning to use cable or satellite TV, then a primary (analog) tuner is simply not needed.
Acoustic system
The presence of the acoustic system.
All original TVs are equipped with speakers, otherwise there would be no sound. This field is less sensitive to plasma panels and projection televisions. Stinks can occur either with or without an acoustic system. If you plan to buy a home theater and buy a wide range of high-channel acoustics, then you do not need an acoustic system that includes both a plasma panel and a projection TV.
Antividblisk
The presence of a special coating on the TV screen, which significantly changes the display on the screen and reduces the glare from external lighting.
Vologozhestey Corps
TV sets can be used in places with a high level of moisture: in the bathroom, shower cabin, swimming pool, on a yacht.

Possibility of wall mounting
Possibility of mounting the TV on the wall.
This function will help protect the space around the apartment. The trace must be folded, so that for mounting it on the wall you will need a special bracket, which requires a sealant.
Hour of video pixel(from 0.5 to 180 ms)
An hour of viewing pixels on the TV screen.
This parameter is valid for televisions created on the basis of PK technology. Due to the peculiarities of this technology, when a signal is applied to the core, the pixel does not immediately begin to light (or dark), but only after a short period of an hour (8-30 ms). Due to this effect, when watching a video on an RK TV with a high hour of pixel input in dynamic scenes, a light trail may appear on loose objects. The shorter the hour you watch, the brighter the TV can produce more dynamic video.
Get ready Blu-ray player

The TV has a DV interface (IEEE 1394).
The DV interface (IEEE 1394) is designed to transmit video to audio in digital form. This interface is widely expanded for video cameras in the miniDV format. Using this additional interface, you can connect a video camera or digital video recorder to the miniDV standard to your TV.
DVI input
The TV has a DVI input.
The DVI (Digital Visual Interface) interface is designed to transmit video signals in digital form. DVI is equipped with a large number of RK monitors, RK TVs, and plasma panels. As long as the video signal is transmitted in a digital format, the images are output without delay or conversion. If your TV has the ability to connect DVI, then to capture high-quality images, it is best to use this interface itself.
DisplayPort input
The TV has a DisplayPort input.
The DisplayPort interface will expand the range of computer technology. It is used to transfer video and audio to digital video. This interface has DPCP (DisplayPort Content Protection) protection against illegal copying. DisplayPort is positioned as a replacement for DVI and a competitor to HDMI. Compatible with these interfaces, they have a wider data transmission channel and a greater maximum cable capacity.
HDMI input
The TV has an HDMI input.
The HDMI (High Definition Multimedia Interface) interface is used to transmit video and multi-channel audio to digital video. This interface is equipped with HDCP (High-bandwidth Digital Content Protection) protection against illegal copying.
HDMI was created specifically for the new high-definition digital television standard - HDTV; it is equipped with almost all TV models that support the new digital television standard.
The HDMI interface is the same as DVI. With the help of a special adapter, the DVI connector can be connected to HDMI and used to transmit a digital signal. Please note that this connection only transmits a video signal; to transmit audio, you will need to install an additional cable. To transfer the image from the device to the stolen video content, a DVI interface with HDCP support is required.
Since you have a number of interfaces to choose from to connect an external signal to your TV, you need to give priority to the HDMI interface, which will ensure the best picture clarity.
HDMI input on front or back panel
The TV has an HDMI input on the front or back panel.
div. "HDMI input").
RGB input
The TV has an RGB input interface.
RGB interface for video signal transmission purposes. The video signal in this type consists of several warehouses: signals of the main colors (red, green and blue), from which the images are formed, and synchronization signals. All RGB signals are transmitted via adjacent wires, which allows the video signal to be transmitted with maximum brightness.
As you have the ability to select the interface for connection, you should give priority to RGB (especially for TVs with a large diagonal). The culprit for this rule may be the lack of a digital video interface.
Often, RGB signals are transmitted via a SCART connector; on expensive models of TVs with a large diagonal, the RGB connectors can be either three or five RCA or BNC connectors.
S-Video input
The TV has an S-Video input.
The S-Video (Separate Video) interface is dedicated to transmitting video signals.

Diagonal(View 3 to 152 inches)
Diagonal to the TV screen.
The diagonal of the screen is determined as the distance between the two sides of the screen. Measured in inches (one inch is equal to 2.54 cm).
The diagonal shows the size of the TV and the capabilities of its choice. So, for example, TVs with a diagonal of 14" are perfect for the kitchen or children's room. For comfortable viewing of videotapes, a TV with a diagonal of 21" or larger is required. The capabilities of a DVD player are increasingly revealed only on a TV with a diagonal of 29". TVs with a screen of at least 32" can be the basis for a home cinema.
Dynamic contrast(View 176 to 150000000)
The value of the maximum contrast on a TV is based on the dynamic contrast mode.
Contrast is the ratio of the maximum brightness of the screen (when showing a white field) to the minimum brightness (when showing a black field). This value indicates the production status before the transfer of substations and subtons.
Dynamic Contrast mode analyzes the image and adjusts the brightness level according to the image. Skin films have both light and dark scenes. While the eye absorbs the brightness of the frame, then in light scenes there is no amount of black in the dark areas of great significance, and yet. Therefore, in a light frame, the brightness increases, and in a dark frame, it decreases in order to better display the black color. This allows you to color the image during dark or bright scenes. Dynamic contrast is the difference between the maximum brightness of the screen in a light frame (when showing a white field) to the minimum brightness in a dark frame (when showing a black field).
Please note that dynamic contrast cannot be compared to extreme contrast. To objectively assess the TV's brightness, it is recommended to adjust the values of the "Contrast" field.
Internet access
Possibility of accessing Internet services directly from the TV without additional devices.
Access to online content requires the use of additional widgets (interactive programs) that can be manually accessed from the TV remote control.

Please note that disks of this format are rarely tested.
Support WMA
Possibility of creating music files in WMA format from an optical disc or memory card/USB flash drive.
WMA is a music file format developed by Microsoft. Just like in MP3, when encoding WMA there is a constraint with insignificant costs in terms of space. An important feature of this format is the compression of audio data at low bitrates (speed of audio data flow).
Wi-Fi support
The TV has an interface (margin adapter) for wireless Wi-Fi data transmission.
With additional Wi-Fi, you can connect to a drone-free network and view multimedia content (movies, music, photos) that is on your computer’s hard drive on your TV.
Some TV models do not have Wi-Fi installed, but the ability to use an optional (optional) adapter is limited. For this you need a compact Wi-Fi module with a USB connector. The list of Wi-Fi adapter models that are recommended can be found on the manufacturer’s website.

Progressive rosette
The TV's ability to format video in progressive mode.
The image on the TV screen consists of adjacent image points (pixels), which are grouped along horizontal lines - rows. The rows are drawn one by one and the frame is formed. Rozgorka is a method of forming rows and frames. There are two types of growth: alternate and progressive. In the first phase, under the hour of marking the frame, all the unpaired rows are displayed, and then all the paired ones. In another type, the rows are created in order, one by one. Most TVs have a vikorystka vortex.
A progressive vortex is used in all computer displays and ensures that the paint color is evenly equal to the row: it eliminates the “comb” effect that appears when objects are moved horizontally, and it eliminates three thin horizontal lines their lines, the brilliance of the indestructible image is enhanced.
Projection system
Image shaping technology for projection televisions.
Today, the following technologies are being used: RK, ELT, DLP, LCoS.
ELT. The images are formed from three kinescopes, each kinescope projects images of one of the three main colors through an optical system onto a matte screen, resulting in a color-matched image.
Advantages of EPT technology: seamless color transfer, improved design, low price. In short, you can identify problems with the combination of three colors, high heating of the system and noisy operation of the refrigeration system, large dimensions and noise of the TV.
LCD. Such systems have three RK matrices of the main colors or one color. The matrices are illuminated by the intense light flux of the lamp, and the image is captured and projected onto a matte screen.
Projection TVs based on PK technology contain all the advantages and disadvantages that this technology carries. Main advantages: compactness, relatively low varity, high brightness. In short, you may notice problems with color transfer, pixel loss, and also the need to introduce a large amount of heat, as seen when working with a projection lamp.
DLP. The core of the system is a matrix with micromirrors, which forms the image. The skin from the dark mirrors can be rotated slightly under the influx of a signal from the camera and thus create a light or dark pixel of the image. The light from the lamp is reflected from the mirror matrix, passes through color filters and finally transforms into images on the matte screen.
The advantages of DLP technology are high brightness and contrast of the image, accurate transmission of colors. Due to the shortcomings, it can be seen that the images are slightly smaller in some models.
LCoS(Rare crystals on silicon) - a completely new projection system. The images are formed lightly under the lamp as they pass through rare crystals and emerge from the mirror surface beneath them. LCoS TVs are designed to display the picture, which has the following advantages: high image clarity; the presence of a “grid”, characteristic of projection televisions on the Republic of Kazakhstan; direct transmission of colors; good brightness and contrast.
Currently, there are two main manufacturers of projection LCOS TVs - Sony and JVC. Sony calls its LCOS technology SXRD (Silicon X-tal Reflective Display), and JVC calls it D-ILA (Direct Drive Image Light Amplifier).
Dolby Digital Processor
The TV has a Dolby Digital processor (decoder).
Dolby Digital is one of the most advanced audio formats available for multi-channel 5.1 audio. Most DVD films have audio tracks recorded in Dolby Digital format.
With a Dolby Digital processor (decoder), you can connect a multi-channel audio signal from a DVD player or other device to your TV and watch a movie with surround sound.
Size of recalled memory(Vіd 2.0 up to 500.0 GB)
The amount of memory of the installed hard drive or installed flash memory for video recording.
Depending on the size of the stored memory, set the maximum recording hour. To record one or two programs, 4-8 GB is enough. Anyone who plans to record a large number of shows and movies is recommended to upgrade to the model with 100 GB of built-in memory.
Dozvil
Separate TV screen.
The separate size of the screen shows the number of pixels (horizontal and vertical) from which images are formed. The more separate the screen, the clearer and more detailed the image on the TV.
To watch TV programs and DVD films, separate resolutions of 800×600 or 852×480 are sufficient. If you are going to use your TV as a monitor, then choose a model with a separate display (from a number of horizontal points - 1024). To watch video programs on a high-definition TV standard, it is necessary for the vertical separation to be at least 720 (Div. "HDTV Support"). For a comfortable viewing of movies at the most popular mode today - 1080p (Full HD) - you need a TV with a separate 1920x1080 resolution.
Let's open SCART
The TV has a SCART connector.
SCART is a universal switching module that can accommodate a whole set of other interfaces. SCART can enable the following interfaces: composite video, S-Video, RGB, audio (both in stereo mode and in mono mode).
The SCART connector is used to connect an external video and audio signal to the TV, and in some cases the output signal can be received through this connector (for example, to record a TV show on a VCR).
Subwoofer
The TV has a subwoofer.
Subwoofer is a device designed to provide low frequency signals (up to 100 Hz). The original speakers are simply physically unable to produce deep, truly low bass. In order to get good low frequencies, a subwoofer is required in addition to the speakers.
Stereo sound
The TV has stereo speakers.
The stereo mode allows you to create a panoramic sound picture, disseminating people's voices, sounds, and music to their exact position on the screen.
Please note that there are TV models with stereo speakers, otherwise you will not be able to receive TV programs with stereo sound ( div. "An encouragement to NICAM stereo sound"). With such models, you can enjoy stereo sound while watching movies from an external device (for example, from a DVD player or VCR).
The total intensity of the sound(type 1 to 200 W)
The sound of the TV's acoustic system is extremely loud. The thickness of the sound indicates the loudness and strength of the sound of the TV's acoustic system. As a rule, louder acoustics when the sound is played at low volume produces less noise, lower acoustics are less intense. With tight acoustics and a richer world, you can appreciate the clear sound of a TV show and sound effects in a DVD movie. Middle-class TVs expect a 2-5 W sound system. TVs have a larger thickness (tens of watts) (with a diagonal of more than 25").
Sleep timer
The TV has a sleep timer.
The sleep timer is a device that allows you to program your TV to turn off at a certain period of time (set the time period to 15 minutes). After the set time interval has ended, the TV will automatically switch to standby mode.
Teletext
Possibility of receiving teletext on TV.
Teletext is an information system that ensures the transmission to owners of television sets of various information in the form of text in addition to the latest television programs. Information is displayed as a structured text, divided into thematic sections. You don't need to check for the latest issue of news to find out, for example, the weather forecast, for the help of teletext, you will find it practically mittevo.
You can navigate through sections and pages using the remote control.
Sub-Field Driving Technology
The firing frequency of the plasma panel is based on Sub-Field Driving technology.
Sub-Field Driving technology is used in plasma TVs to improve image clarity and color accuracy. The higher the frequency, the more effective the technology.
The type of TV depends on the screen manufacturing technology. Possible types of TVs: ELT, ELT flat, RK, projection, plasma panel.
Televisions based on electron tubes can be either a “standard” or a flat screen. “Original” EPT TVs have a slight convexity to the screen, which leads to slight interference with the geometry of the picture. An undeniable advantage of flat-screen EPT TVs is the constant presence of geometric elements and the presence of glare on the surface of the kinescope.
TVs and TVs based on rare crystal matrices (RC) have become more sophisticated. Such TVs are even more compact, offer high separation and good picture clarity. Due to shortcomings, you can notice a decrease in the brightness of the image depending on the hour of viewing under the camera. Nowadays, LCD TVs are produced in a wide range of virtually any sizes. You can choose your own model for any place - from the kitchen to the home cinema.
Projection TVs occupy an intermediate level between basic TV receivers and plasma panels. The operating principle of such a TV can be understood from its name. In the middle of the body is a large projector that projects images onto a matte screen. The advantages of a projection TV include the ability to display large images, good sound clarity, a completely flat screen, and an equally low price (for TVs with a large diagonal). The shortcomings can result in large dimensions.
p align="justify"> The operation of the plasma panel is inspired by the principle of operation of neon lamps. The von is a matrix of centers filled with an inert gas and coated with a phosphor. At the skin center there are electrodes with high voltage, which causes an electric discharge and the gas is converted into plasma. The plasma of the gas discharge produces light in the ultraviolet range, which in turn produces a glow of the phosphor in the visible range for humans.
Due to the peculiarities of the technology, the size of such centers cannot be made smaller than a small size; therefore, plasma panels are not produced with a diagonal size of less than 32 inches.
Plasma panels allow you to capture wonderful images: brighter, more contrasting, clearer, and are ideal for watching in a home theater. The shortcomings can be attributed to the high price and terms of service.
OLED TVs have low energy consumption, high contrast, clear color reproduction, and images on the screen can be seen almost anywhere. Even a high level of quality can be reserved for short quantities. In addition, only OLED TVs with a small diagonal are currently being released.
Type of LED backlight
Current TVs have different implementations of LED backlighting: Edge LED and RGB LED.
Edge LED is based on white LEDs installed on the sides of the PK matrix. A special light-colored coating allows you to adjust the light level of the screen evenly. The Edge LED backlight accommodates a significant change in the thickness of the TV (from 10 cm to 2-3 cm).
To implement RGB LED illumination, a matrix of light-emitting diodes of three main colors (red, green and blue) is created, evenly distributed across the entire surface of the screen. This design allows you to set the brightness and backlight color for the surrounding area of the screen, depending on the image that is displayed. This results in improved picture clarity and increased contrast. TVs with RGB LED backlighting are more expensive than models with Edge LED.
I'll take a look around(from 7 to 180 degrees)
I look around the TV screen.
This parameter is valid for RC TVs and plasma panels; for other types of TVs, you can use a viewing angle of 180 degrees. Due to the technological features of image shaping, the brightness of the image on the screen may shift, as the viewer is looking at the screen under a direct cut. When you increase the color value by a significant amount, the contrast changes and the colors change.
When looking at TVs, you will notice that the image contrast is as high as 10:1. For a comfortable view, you can adjust your view to 160-170 degrees.
Universal (multi-brand) remote control
The ability of the remote control to operate is not limited to a TV, but also to other electronic equipment (DVD player, AV receiver, CD player and other devices).
Multi-brand remotes are combined with the technology of different manufacturers.
The choice of a universal multi-brand remote control will allow you to get rid of a large number of different remote controls and only have one.
Device for reading memory cards
The TV is equipped with a device for reading memory cards.
A TV that contains a memory card reader can display images and videos recorded on memory cards. This capability would be a welcome addition to the basic functions, especially for those who use a digital camera.
TV format
The TV format is defined as the ratio of the width of the screen to its height.
Most TVs can be divided into two types of formats: 4:3 (normal) and 16:9 (widescreen).
The 4:3 format broadcasts terrestrial TV programs, so if you spend most of the time watching TV programs, then you should choose a TV of the same format. All TV models with this format allow you to display images in 16:9 format. In this case, the picture appears on the outside, except with the black fields of the animal below.
On the territory of Russia there is no talk about the 16:9 format. Therefore, this format is only relevant for receiving TV programs from satellites, for cable TV, and for watching recordings from video discs. Most films on DVD are recorded in 16:9 format and a wide-screen TV is required for comfortable viewing. This fact should be taken into account when choosing a TV for your home cinema. TVs with a screen format of 16:9 allow you to watch the same programs as in the 4:3 format, but in this case a small part of the image is cut off at the bottom, and right- and left-handed people are deprived of blackness.
Time Shift function
The TV has a Time Shift function.
Time Shift allows you to “zip” the showing of on-air TV programs at any moment, and then continue watching them from the recording from the very moment when the zup was broken. When you press the "Pause" button, recording of TV programs begins, and the "Start" button starts the creation of the recorded video.
Update frequency
Frequency of updating the image on the TV screen.
Most TV models have a refresh rate of 50 Hz (a frame is refreshed 50 times every second). On TVs running at 100 Hz, the images on the screen appear at a sub-frequency. At this frequency, the thin screen on televisions with cathode tubes (CRT) is practically not detected by the human eye, and the images on the screen are captured much more clearly.
On RK TVs, a firing frequency of 100 Hz allows you to avoid the effects of “ragged” rudder and rudder that occur when an object is moved quickly across the screen (for example, when a football or tennis ball is thrown). The technology works like this: using a special algorithm, an analysis of the last two frames is carried out, after which an additional frame is created, which is inserted between the two original ones. As a result, the number of frames doubles, which gives the camera additional smoothness and realism.
The 200 Hz firing frequency on RK TVs can be adjusted in a variety of ways. The first method is used by Sony and Samsung and follows the same principle, with a firing frequency of 100 Hz. The main difference lies in the fact that between the two original frames, not one, but three additional frames are inserted, which gives the flow even greater smoothness.
Another way to remove the frequency of 200 Hz is Scanning Backlight technology. With this technology, only one additional frame is created, like on TVs with a frequency of 100 Hz. The 200 Hz effect is achieved by slow-moving high-frequency lights, which helps to blur the image. It should be noted that the brightness of the picture created using this method of trimming 200 Hz is still compromised.
On TVs with high refresh rates (400 and 800 Hz), there is a combination of two technologies: the creation of intermediate frames and the creation of slow-motion backlighting. Not all new technologies significantly improve the brightness of the picture, so up to large numbers, as TV manufacturers indicate, they are installed with care.
Widescreen
TV screen format.
The TV format is determined by the relative sides of the screen (width to height ratio). Wide-format models display the screen on opposite sides 16:9, 16:10 or 21:9. Such monitors are perfect for watching movies and for daily video games (some movies come from the same sides 16:9 or 21:9, and games come from the other sides 16 :9, then when viewed on a widescreen TV, the entire area of the screen is covered - at that hour As on 4:3 TVs, most of the screen is deprived of non-vikoristan).
On-screen menu in Russian
All menu items are displayed in Russian language.
Today's televisions are increasingly becoming more complex and functional, and the number of different channels is increasing. Navigating the numerical adjustments will be much simpler, since the menu on the TV is displayed in Russian language.
Yaskravist(v_d 100 to 2000 cd/m2)
The brightness of the TV screen.
Brightness is measured in candelas per square meter (cd/m2) and is an important parameter for plasma panels, RC TVs, and projection TVs. High brightness is important if the TV is operating in a high-light environment; with low brightness, the image will be overexposed.
Brightness varies from 300 cd/m2 for RK TVs and up to 2000 cd/m2 for plasma panels. The greater the brightness of a TV, the greater its potential for creating a bright image.
The component input on the TV allows you to significantly improve the brightness of the image. This is especially true for watching TV shows, but also when choosing it as one of the components of a home cinema.
Is component input currently being used?
The component input is a three-cable connection:
- one cable for transmitting brightness and synchronization signals, marked with a yellow-green circle and the Y symbol;
- they are responsible for the color difference;
- the other - for the difference in the level of blue color and brightness, that one is marked with a round sticker of a blue color and the symbols Pb or V;
- the third - for the difference at the level of the red color and brightness, then for this marking, put together the red color and the symbols Pr or U.
Through this socket, DVD players and satellite receivers are connected to the TV. This bandwidth allows you to convert an analog signal to a suitable digital format:
- alternately (1080i) – for all television broadcasting systems;
- progressive (1080p) – for HDTV standards.
Where do you know?
Finding the component input is not difficult The same connector is used to connect devices for washing robots paired with a TV, most often without connections on the rear panel.
Thus, careful attention to the color scheme and control of the brightness and synchronicity of this display increases the clarity of the picture and its saturation. In addition, on the parameters of the image brightness, you can add ways to revert the signal through a pixel row or by a new set.

In past articles we learned about media and file formats, about the main multi-channel audio formats, and also about technologies of trivial sound. This time we are talking about different types of connections for audio and video signals.
Video signal transmission interfaces
Composite interface
The oldest of the established types of connection. Cheap TVs have a single video input. One RCA (tulip) type socket, usually a yellow color.
In the VHS era, this method of transmitting video was unified, and with the advent of DVD, new ways of connecting video devices to a TV appeared that would provide greater image lucidity.
To the advantage composite video interface You can include those that are equipped with almost all televisions. The main shortcoming lies in the fact that it slightly coarsens the images, collecting other details.
S-Video (or elseY/C)
Interface S-Video (Separate Video) is used to transmit a video signal. Є a round multi-contact connector in which the color (C) and brightness/synchronization (Y) signals are connected around the edges (sounds and names - Separate Video).
Adhering to this standard will ensure poor image clarity when stuck on simple DVD systems, and on high-quality processors and TVs it gives a noticeably “silent” picture. The difference is like the image between composite interfaceі S-Video This can only be seen on TVs with a large diagonal (25 inches or larger).
Component interface (or YUV)
There are three RCA type sockets in green, red and blue colors, which are designated Y, P/r, P/b (or Y, C/r, C/b). The two wires transmit brightness/glow signals (Y) and two color signals (U and V). This format itself encodes color information when recording on DVD, as well as broadcasting broadcasts.
This type of connection allows you to select the brightest image for the TV (for the TV itself, since the residual signal processing is carried out in its path). Thoroughly evaluate all the advantages component interface Only possible on TVs with a large diagonal (29-36 inches or larger).
This is a standard interface for computer monitors, video projectors, plasma panels and RK TVs. It includes signals of the three main colors, synchronization signals and a special channel for transmitting service information. Interface VGA Allows you to transmit video virtually without confusion, with a very high yield. If you are interested in HD D-Sub 15 pin.
DVI interface
Interface DVI (Digital Visual Interface) is used to transmit video signals to digital video. As long as the video signal is transmitted to the digital viewer, the images are transmitted without any need for confirmation or re-encoding. Suitable for transmitting video to digital imaging devices, such as PK monitors and projectors.
Data format that is vikorized in DVI, based on PanelLink, a serial data transfer format developed by Silicon Image. Vikorist technology of high-speed transmission of digital streams TMDS (Transition Minimized Differential Signaling, differential transmission of signals by minimizing level differences) - three channels that transmit video streams and additional data without skipping up to 3.4 Gbit/s per channel.
Single link DVI consists of four twisted pairs (red, green, blue, and clock) to ensure the ability to transmit 24 bits per pixel. It can reach the maximum possible resolution of 2.6 megapixels at 60 Hz.
There are three types DVI: DVI-A- Only analog transmission, DVI-I- analogue and digital transmission, DVI-D- Less digital transmission. In case of analogue gear, the Building of the RGB-signal of 400 MHz (-3 DB) is reached, with digital transmission minimal Takov, the frequency to begin to 21.76 MHz, the maximum frequency in a single regime is 165 MHz, the maximum frequency in the submarine regime is estimated.
Audio transmission interfaces
Line output
This is the main interface for transmitting audio signals between other components of the music complex. This interface is used for connecting stereo speakers; therefore, with a multi-channel speaker system, this connector will not be blocked.
Microphone input
Microphone input purpose for connecting a microphone. The microphone can be adjusted to enhance the sound of the human voice, karaoke, and surround sound calibration. The number of such inputs indicates how many microphones can be connected simultaneously.
Output to headphones
Headphones are designed for individual listening to music, maintaining silence in the living room, for example, at night. Connecting headphones directly to the home theater can be manual, since the TV does not have a headphone output. Headphones can also listen to music discs without turning on the TV.
Subwoofer output
A subwoofer is a special device for producing low-frequency bass sounds. During the hour of watching movies, the subwoofer helps to create the sounds of gunshots, knocks, etc. Many high-channel power amplifiers and AV receivers have an output for connecting an active (with power amplifier) subwoofer.
There are six line-in (RCA) connectors that are configured to transmit multi-channel 5.1 audio in analog form. Most home cinemas are equipped with this output.
6.1CH
These seven line connectors are designed to transmit multi-channel 6.1 audio in analogue form. Using this additional interface, you can connect to a powered media player, powered device, or a 6.1 sound card.
All line inputs are used to transmit multi-channel audio to the 7.1 standard in analog form. The 7.1CH socket is used to connect a tension booster or active speaker system to the 7.1 standard to a home theater.
Coaxial interface
Coaxial input It is used to transmit a digital audio signal, and through this interface it is possible to transmit both multi-channel and stereophonic sound. To connect via digital coaxial input You can use a simple shielded audio cable with an RCA connector (“tulip”).
Optical output
Vikorist is used to transmit digital audio signal via optical cable. Through this interface you can transmit both multichannel and stereophonic sound. 3 perevag optical interface can be considered those that are susceptible to theft due to electrical faults.
Mixed interfaces (for audio and video)
RCA jack(also titles phono connector, or CINCH/AV connector, as well as in the open air " tulip") - a standard socket that is widely used in audio and video equipment.
Name RCA Similar to the name of the Radio Corporation of America, which introduced this type of connector in the early 1940s for connecting phonographs to boosters.
In Russian language, a similar type of rose is often called a tulip.
Roz'emi RCA The transmission of video signal and stereo audio signal is limited: yellow - for video signal, white - for mono audio signal and the left channel of stereo audio signal, red - for the right channel of stereo audio signal.
SCART (or Euroroz)
European standard for connecting multimedia devices such as TV, VCR, DVD player. The same age as the composite interface, the introduction of the French distributors of radio and television equipment Syndicat des Constructeurs d'Appareils, Radiorecepteurs et Televiseurs (abbreviated) SCART). Other names: Peritel, Eurorose, Euro-AV.
SCART unifies the connections between different devices, connecting all the necessary signals in one multi-pole plug. A flat 21-pin connector that can output video signals of various formats, stereo audio signals, as well as digital signals. The shape of the plug is cumbersome and fits the plug in a mild manner. Smaller connections require physical force to connect or disconnect the socket and plug.
Today, TV or video equipment for Europe is equipped with at least one SCART. Before the standard appeared SCART A large number of different roses were used, which often complicated the connection of devices made by different companies. The differences depend on the physical connection of the connectors and the specifications of the signals.
DV (IEEE 1394)
Serial transmission interface. In some cases, you can use it to transmit audio and video signals. A wide range of camcorders in the miniDV format has become available. Using an additional interface, you can connect a DV video camera to a DVD recorder and immediately record video from it to a DVD disc.
When recording digital video cameras for connection, it is important to use the digital interface rather than the analog one DV (IEEE 1394). Selecting a digital interface will eliminate the loss of power that occurs when choosing analog video interfaces (composite, S-Video).
HDMI interface
HDMI (High-Definition Multimedia Interface- high-quality multimedia interface) – digital connector, which has two types of small-sized connectors: 19- and 29-pin. Either option will ensure the transmission of eight-channel audio in 192 kHz/24 bit format and a video signal that meets high-definition TV standards. Uses a digital decoder on your TV.
HDMI The capacity of the building ranges from 4.9 to 10.2 Gbit/s, even if the cable is recommended to be 1.5 m, it can be connected at a distance of up to 5 meters. The standard supports other CES and European AV.link protocols.
Its interface is equipped with HDCP (High-bandwidth Digital Content Protection) technology to protect against illegal copying. And the daily replacement of analogue connection standards, such as SCART or else RCA. This is the most promising format for the near future, and from a format that is beyond the pale for a classic DVD. Interface HDMI back crazy DVI.
DisplayPort
A new standard for the signal interface of digital displays. Adopted by VESA (Video Electronics Standard Association) in 2006. DisplayPort It is transferred to the most popular interface for connecting audio and video equipment, especially for connecting a computer with a display, or a computer and home theater systems.
Supports HDCP version 1.3 and has twice the throughput of Dual-Link DVI, low voltage and less sensitive to third-party signals, the size of the Mini DisplayPort connector is approximately the same as USB.
Technology implemented in DisplayPort, allow you to transmit simultaneously both graphic and audio signals. Main activity HDMI- wider data transmission channel (10.8 Gbit/s instead of 5 Gbit/s), which ensures high resolutions. Maximum cable allowance DisplayPort vrichi more, lower HDMI- 15 meters versus 5. Well, instead of HDCP, copy protection will be implemented using DPCP (DisplayPort Content Protection) technology with 128-bit encryption.
Universal connectors (for connecting external devices)
USB
USB- Serial interface for data transfer. There are two types of interface, which are divided by the shape of the connector: USB Type Aі USB Type B. Interface USB (type A) It is required to connect to a home theater USB flash drive or an external hard drive supporting this interface. On a home theater with a USB interface, you can listen to music and watch video files recorded on a flash drive. For help at the port USB (type B) You can connect your home theater to your PC and listen to music or watch videos from your computer.
Ethernet
The technology of transmission in computer networks has been expanded, almost all daily computers are equipped with an interface Ethernet. Additionally, you can connect your home cinema to your home local network and view photos, videos saved on your computer’s hard drive, and listen to music in MP3 format. Home cinemas have an interface Ethernet Select 10/100BASE-T Ethernet from an RJ-45 connector.
RS-232- Serial interface for data transfer. Through this interface, with the help of special software installed on the computer, you can remotely change the settings of your home cinema. For some models through RS-232 You can change the firmware of digital devices or change technological parameters.
FireWire (iLink)
FireWire (iLink) - Serial data transfer interface. In some cases, you can use it to transmit audio and video signals. In AV amplifiers and receivers, select the number of audio and video inputs. With their help, you can connect all your audio and video equipment. On the remote control of the booster, you can select the desired sound to enhance or AV signal to watch on TV.
Druk
On older TVs there was only one input - analog, antenna, high-frequency. Nowadays there are more than one TV sets TV input , And what seems to be too much, especially on RK TVs. However, this is all for the friendliness of the traders.
Optimal for CRT (CRT) TVs, in my opinion, are 3 TV inputs. Behind, for example, for satellite or digital (which appeared recently) receivers and DVD players, and in front or on the side for a video camera.
RK TVs have even more inputs, in addition to analogue ones, there is also a digital input.
Analog input.
Follow up with them:
- RF input;
- A/V, composite;
- S-Video;
- SCART;
RF input - antenna. This type is used for connecting antennas to TVs, VCRs, cable and satellite “boxes” and DVDs. The bait is caught through such a rose at its finest.
A/V input A well-known type of connection, known to us under the name “tulip”. Ring, yellow-white + red three. Allows you to color the image. Information about audio and video is transmitted not directly through a single channel, but also separately for audio (white - red) and separately through video (yellow).
S-Video input. Not on all TVs. Information about color and contrast is also directly transmitted here. S-Video is widely used and is still an analogue connection, which can often be found on DVD panels, game consoles, etc. It is also often promoted as an alternative option for manufacturers of computer video cards.
SCART. This input has 21 contacts, and today's expansions are possible across Europe. Today, audio, video, analog and digital signals can be transmitted via SCART, depending on specific specifications.
VGA – input. Found mainly on new TVs, the main function of this input with 15 doors is one - to serve as a contact for connecting a personal computer. Therefore, make the VGA input on your TV identical to the input on your computer analog monitor (D-sub 15-pin).
Digital
You can see them DVI and HDMI come in. These outputs are designed to transmit HDTV digital video without the slightest constraint. HDMI is differentiated from DVI so that in addition to digital video, it can transmit rich-channel digital audio. And, although there are plenty of different types of both interfaces, most of them are miraculously mutually intelligible and can be analyzed simultaneously using the simplest adapters. In addition, the interface is perfectly suitable for connecting a computer to a computer. DVI and HDMI support the HDCP protocol, which protects licensed content from unauthorized rewriting.
