Connectors

If the number of connectors that a SCART adapter can have directly depends on its class, then even a standard satellite tuner has three of them:

• the first is intended for connection to a TV;
• the second is used to connect players;
• the third provides the ability to connect a decoder for various “closed” programs.

For the latter, it is especially convenient to use a SCART connector. An adapter from any other cable of this type can also be used - through them the encoded signal will enter the decoder, and then return back in an “open” form. The situation is exactly the same with cable decoders of various paid programs, the use of which can now be carried out using a single cable of this interface.

Design

Many people who want to make a SCART-tulip adapter with their own hands try to understand the design of this interface.

First of all, it is worth noting that there are 20 pin contacts in this connector, and the role of the 21st contact is assigned to a specialized metal screen, which is located along the entire perimeter of this connector. Its second purpose is to protect the contacts from any mechanical influences from the outside, and the mating part is made using plastic injection. It is worth noting that it can have not only lugs for self-tapping screws and screws, but also bosses intended for installation on printed circuit boards.

The design of cable connectors of this type can hardly be called original, however, there are three main types that differ from each other in the design of the housing - the cable can be routed straight, at an angle or to the side. The connector is held in the socket by specialized spring-loaded male contacts, thanks to which even the SCART-USB adapter is famous for its incredible reliability and fastener strength

Even such cables have to be inserted quite carefully so as not to move the device.

HDMI adapter tulip. Review, characteristics, application. How to choose the right HDMI adapters

Of course, you won't be able to buy an adapter on this page. But we have prepared for you a complete guide on the use and features of HDMI - this information should help you in your choice!

Since the HDMI interface has gained popularity and is now used in many multimedia devices, we could not help but write about it. Or rather, let’s look at one of the connection options - to be precise, we’ll talk about the hdmi tulip adapter. We will figure out what it is, its characteristics, price and other details.

Here's a quick overview:

SCART connector. Description and pinout of SCART

The SCART connector (also called Peritel, Euro-AV or simply Euro-connector) is a special type of connector used in televisions and devices that are designed to work with it, such as VCRs, set-top boxes, DVD players and DVD recorders. This standard was created in France in 1977, and SCART became widespread in 1980.

This connector makes it easy to connect a variety of devices. It incorporates all the necessary signals (audio and video), which are output to a multi-pin plug. Today, almost every television or video device produced for Europe is equipped with a SCART connector. Analog and digital signals are exchanged through it.

SCART pinout

The SCART connector contains 20 pins, each of which can receive or transmit a specific analog signal. The metal edge of the connector (21 pins), as a rule, is connected to the shielding braid of the cable, which in turn helps protect the video signal from various interferences.

The outer metal frame is not symmetrical, which avoids incorrect connection of the connector to the socket. Below is the pinout of the SCART connector:

Pin 8 is designed to switch from an internal signal (TV) to an external signal source and has three levels:

• 0…2V (nominal 0V) – TV mode
• 5…8V (nominal 6V) – widescreen mode (16:9)
• 9.5… 12V (nominal 12V) – normal mode (4: 3)

Pin 16 is used to switch the TV from RGB to Composite mode and vice versa:

• 0...0.4V - composite video signal
• 1…3V (nominal 1 V) – RGB video signal

The RGB signal is mainly used to connect high-quality audio/video devices, such as a satellite receiver, to ensure the highest possible image quality. The RGB line only works as an input.

The big advantage of the SCART connector is that it includes three video standards:

• S-Video (contacts 15:20),
• Composite video signal (pins 17/19 or 18/20)
• RGB (pins 5, 7, 9, 11, 13, 15)

So you can assemble a simple adapter, for example, RGB-SCART, VGA-SCART, simply by connecting the corresponding pins. In addition to this, the SCART connector has pins for audio signal (pins 1, 2, 3, 4 and 6).

The main disadvantage of the SCART connector is significant signal loss as the cable length increases. In theory, each individual wire of a cable carrying a useful signal should have a braided shield, which is actually rare, since this significantly thickens the cable itself and makes it more expensive.

Another disadvantage is the fact that the data transmission density compared to current digital interfaces such as DVI and HDMI cannot be compared.

But still, thanks to its versatility, the potential of the SCART connector has not yet been exhausted.

What it is?

It is quite easy to answer the question of what SCART is on a TV. This is one of the connectors designed to ensure that the television receiver is used in close conjunction with other devices.

A similar technological solution appeared at the end of the twentieth century. But it is worth noting that trial samples of SCART were introduced back in 1977. The authorship of the idea belongs to French engineers.

It is equally important that the domestic radio-electronic industry quickly picked up this idea. Already in the 1980s, SCART was used very widely. These ports were connected to in different years:

• video recorders;
• DVD players;
• set-top boxes;
• external audio equipment;
• DVD recorders.

But at the initial stage of its development, SCART was not perfect enough. Even the most advanced developments of this kind in different countries suffered from interference. Remote control often caused difficulties. And for a long time it was not possible to ensure the production of cables of the appropriate standard in the required quantity. Only by the mid- or even late 1990s were SCART’s “childhood diseases” defeated and the standard gained the trust of consumers.

Nowadays such connectors are found in almost all manufactured TVs. The only exceptions are certain models that focus on newer versions of interfaces.

The port is divided into 20 pins. Each pin is responsible for a strictly defined signal. In this case, the perimeter of the SCART port, covered with a layer of metal, is conventionally considered the 21st pin; it does not transmit or receive anything, but only cuts off interference and interference.

Important: the outer frame is devoid of symmetry quite deliberately. This allows you to avoid errors when plugging a plug into a port.

The 8th pin is designed to transfer the internal signal of the TV to an external signal source. Using pin 16, the TV changes the composite mode to RGB or switches back. And pin inputs 15 and 20 are responsible for processing the S-Video standard signal.

How to connect video to domestic TVs

The lucky owners of the Japanese or South Korean miracle soon came to the conclusion that our televisions could well be used to watch foreign video programs. Most Soviet devices, modern at that time, already had all the necessary devices for connecting video equipment, namely: a built-in PAL-SEKAM decoder and a SCART connector on the back cover. They were also equipped with remote control or had the ability to easily install the necessary boards, control modules and infrared signal photodetectors. A shortage immediately arose for the appropriate connecting cables, which was readily filled by numerous cooperatives and private enterprises.

How to use?

But even the negative aspects do not interfere with the popularity of such a standard. The fact is that the connection is quite simple - and this is what is primarily required for most TV owners. Let's say you need to connect a TV to a personal computer using a Euro SCART connector. Then one end of the cable is connected to where the video card is located.

If the procedure is performed correctly, the TV will automatically turn into an external computer monitor. You just need to wait until the pop-up window appears. It will notify the user about a new device found.

It will take some time to install the drivers. They may be placed incorrectly if:

• no signal;
• the video card is not configured correctly;
• outdated software versions are used;
• The horizontal sync signal is too weak.

In the first case, you must first turn off all devices that may be a source of interference. If this does not help, then the problem is related to the operation of the connector itself. Video card failure is usually resolved by manually updating drivers. But sometimes it turns out that it does not support SCART in hardware. And if the signal is too weak, you will definitely have to resolder the connector itself; a new setting at the software level is often necessary.

Contact distribution

The SCART connector is equipped with several groups of contacts that provide transmission of certain signals from the TV and back:

• 5 lines for transmitting and receiving audio;
• 9 lines for receiving and transmitting video signals;
• 2 lines for selecting modes;
• 3 lines for digital data transmission.

All lines are marked in different colors, which greatly facilitates the process of installation and connection of various devices. SCART is still very popular among a large number of users.

The scart implemented the ability to transmit stereo audio signals, which was later transferred to other more modern types of HDMI connectors. Due to the design features of the connector, data transfer is possible when controlled remotely. You can also connect unmodulated signals:

• composite;
• component;
• S-Video.

Component video signals include RGB and YPbPr. And S-Video includes 2 lines. The function of switching video signal reception modes and waking the TV from sleep mode upon command from an external device was added to the connector only in the late 80s. In the same years, SCART was supplemented with 2 video signal transmission lines S-Video.

Although the interface is large and inconvenient, many manufacturers still install it in their equipment with the expectation of using it to connect to old TV receivers. And in order to connect other types of devices to it, for example, a video camera, you will need a special adapter.

Description of the purpose of some pin groups

SCART is equipped with multifunctional outputs; when different voltages are applied, the execution device can be switched to different modes. For example, if there is a 0-2V signal on pin 8, it switches the TV to normal TV operation mode from an external antenna. When a 5-8V signal is applied to this pin, a widescreen mode for displaying pictures on TV is established. And a nominal voltage of 9.5-12V indicates the normal aspect ratio mode.

There is also a multifunctional pin numbered 16. With its help, one of two reception modes is selected: composite signal, RGB . The first requires a signal of no more than 0.4V, and to receive a color-difference signal from 1 to 3V.

The versatility of the connector lies in supporting three operating modes simultaneously:

SCART connector

SCART connector (“Syndicat Français des Constructeurs d'Appareils Connector Radio et Télévision” from French “Association of the Radio and Television Industry”). An analog signal connector, SCART is a physical and electrical connection between two pieces of audiovisual equipment, such as televisions and VCRs, DVD players, and audio equipment. SCART was designed to eliminate confusion with wires and connectors. Developed by Peritel in France and also known as the "EURO connector", the SCART cable uses 21-pin male connectors at both ends. Today, most new televisions and VCRs in the European market and other countries that use the PAL video standard are equipped with a SCART connector.

Bidirectional

Composite video and analog lines are bi-directional, allowing pay TV and teletext to be sent from the TV to the set-top box for decoding and then back to the TV.

A little history

Before SCART appeared, there were many connectors, which created inconvenience when connecting devices of different brands.

In 1978, the subject of our conversation appeared, which combined previously existing interfaces. In 1981, in his homeland it was forbidden to sell televisions without such a socket. And after another 3 years it was accepted as a standard throughout Europe.

At that time, American and Asian equipment was equipped with a “tulip” cable. SCART became its competitor in the European market, and after a while - throughout the world.

Connector pinout

Even such an attractive connector as SCART cannot be used indefinitely. It was replaced by an S-Video connection. It is still widely used in various technologies. To connect to SCART, you can use widely used adapters. The wiring diagram is shown in the picture below.

But an even simpler solution is becoming more widespread - RCA. Separate connection involves the use of yellow, red and white plugs. The yellow and white lines are responsible for stereo audio. The red channel supplies the video signal to the TV. Wiring into “tulips” is carried out according to the diagram shown in the following photo.

Quite often you have to solve another problem - how to connect the old connector and modern HDMI. In this case, you won’t be able to limit yourself to conductors and adapters. You will have to use a device that will “translate” HDMI digital signals into analog and vice versa. Independent production of such equipment is impossible or extremely difficult.

It would be best to buy a ready-made converter of an industrial standard; it is usually small in size and can be easily placed behind the TV.

For SCART connectors, see below.

Those annoying 20 contacts and ground

As a rule, the connecting cord was a cable, on one side of which there was a SCART connector, on the other, two, four or six contact groups of the American standard RCA (called “tulips” for their specific shape). At its core, it was a simple adapter that allowed for galvanic connection of the source with a video monitor (TV). Owners of video equipment often cursed, cursing the imperialists for the lack of desire for universal standardization, believing that 21 contacts for such a simple device was too many.

Only television specialists, for whom the SCART connector diagram did not constitute a “Chinese letter”, were able to appreciate the full potential of this approach on the part of the French Union of Electronics Manufacturers, in honor of which it received its name (Syndicat Des Constructeurs D'Appareils, Radiorecepteurs Et Televiseurs - SCART).

SCART pinout

The abbreviation SCART (Syndicat des constructeurs d”appareils radio recepteurs et televiseurs) is translated from French as “Association of the Radio and Television Industry”. The European unified connector, developed at the very beginning of the eighties, was intended for connecting various devices: a TV with a printer in the Videotext system, a keyboard in the Teletext system, VCRs, video players and Hi-Fi devices, a home computer, etc. The SCART connector is used not only in all European-made devices, but also in most Japanese devices.

Scart pinout - correct pinout

Scart pinout - in the early 80s, the French joint company of radio and television developers designed a multi-pin SCART connector. Using this audio-video interface, it became possible to broadcast data received from RGB signal sources. This device, which provides excellent video quality, quickly became a fairly popular connector in Europe.

Somewhat later, this 21-pin connector found its application in players and video recorders produced by famous world brands. There are currently many popular systems for exchanging information using SCART.

In terms of design, the connector was developed to perform switching of various types of data in digital and analog format. This includes the transmission of audio and video signals, with the help of just one such connector it has become possible to record and play video content. In addition, a command transmission function is available to control the multimedia device during its setup.

Design features and scart pinout

The pinout of the scart connector is made according to a 2-component asymmetrical circuit; double-row spring-loaded male contacts transmit signals (20 are signal paths and 1 for protection). The outer housing of the contact connector has a characteristic shape that serves as a kind of key. It is this structural protrusion that guarantees the correct connection of the SCART; if it is unfolded during connection, the connection will be impossible.

The pinout of the SCART connector is carried out by installing odd numbers of contact blades at the bottom of the connector, while the cable key will be on the right side. The upper row of contacts, which have even designation numbers, is made with some offset relative to the lower row. It is this arrangement of the “knives” that prevents the connector from being connected in the opposite direction. The order of signal data through the contacts is shown in the table below. The protective wire, placed in a braided shield, is connected to 21 contacts.

The need to manufacture a connector with a SCART connector at home may be caused by the need to create a multimedia complex for the home. And the pinout of the scart connector is done according to the table presented. When making a SCART connector yourself, it is not necessary to use all the contacts; you can connect only the ones you need. The place where the wire is soldered to the contact should be placed in a casing, possibly with heat-shrinkable properties.

SCART, as a unified connector, was first introduced by a French company. It was created to optimize signals from devices from various manufacturers. Thanks to the creation of a single format, users had the opportunity to buy models of household appliances from different brands, thereby allowing them to make a choice in favor of comfort, convenience, reliability and practicality.

The introduction of the universal connector was carried out intensively, by banning, starting in 1981, the production of equipment with other types of connections. The new format was introduced as mandatory for all manufacturers without exception. But at the same time, SCART began to be actively used throughout Europe only 3 years later, becoming a standard regulated by EN 50049-1. Due to its format and design, the connector has received many common names, such as comb and ratchet.

Scart to HDMI adapter

If the scart connector can be converted to a tulip or S-Video, then one conductor will not be enough when implementing the same manipulation to obtain an adapter for HDMI. The fact is that HDMI is a digital interface, and analog signals come out of the scart. Therefore, the adapter must be able to convert one signal to another. Special converters are used for this, so it will be difficult to make such a device yourself. It is much easier and safer for yourself to buy a ready-made scart-HDMI adapter

with power supply. The device is implemented in a small case that easily fits in the palm of your hand, so it does not require much space to be placed on the back of the T-receiver.

Of all the analogue options for distributing video images between your AV equipment, this is likely to give the worst performance and as such should be avoided if alternative options exist. Choose only composite video if you have no other alternatives!

AV-SCART connector for connecting Color-TV and DVD

As the name suggests, it's digital and designed for the latest generation of high definition video formats, so you'd expect it to be better, wouldn't you? Whether you have a new piece of AV equipment that you want to connect to your existing system, or, having read above, you want to reconfigure your system for optimal performance, then choosing connection options from the top of this list will give you the best chance of success.

Assuming other connectors exist, devices from different companies may have different and incompatible standards. To do this, he assembled all the analog signal connections into one cable with a unique connector that made misconnections virtually impossible.

Disabling this component makes it the basis for outputting a signal similar to that delivered by the original machine. The kernels that support this option are. In the main documentation. Some of them are commonly used to protect color signals as well as audio signals. But it is also recommended to connect shielding connections to protect analog signals from noise.

So what is SCART (in Russian just “skart”) Where did it come from? As one English magazine wrote, “... due to the fact that the 21-pin connector is inconvenient to connect, it is always located on the back wall of the device, and the efforts applied in this case can not only pull a small TV off the table, but also knock over a large one, we are obliged... to the French." Indeed, it was at the instigation of the French Association of Developers of Radio and Television Equipment (SCART Syndicat cles Constructeurs d'Appareils. Radiorecepteurs et Televiseurs) in 1983 that Europe became firmly hooked on 21 “needles” (pin - needle, contact). But the foresight of the developers of the proposed audio-video interface is worthy of praise. Today, every television/video device produced for Europe is equipped with at least one SCART. What is the reason for this, let's call it that, popularity? In versatility. And although it was solved quite straightforwardly, i.e. number of contacts, the interface, despite its negative aspects, is really convenient. With just one cable you can both record and play back video programs. Here's your first advantage.

The numbers are correct, but pin 6 should not be dimmed, but sticks out. In such cases, some of the existing contacts are used as follows. In this case, the grounds are the same, i.e. on pins 13 and 17. With newer devices, you don't have to worry about how to connect inside the cable because the signal type can be selected programmatically through a menu, and the device itself selects the correct pin combination based on the signal type selected.

Scart-scart cable wiring for video and audio transmission

Such interference primarily manifests itself in the appearance of “ghosts” above the base of the image. It also has a communication data channel to transfer information between devices. Very good compatibility and high image quality. The video signal is divided into luminance components followed by chrominance in red and blue, providing high quality luminance and color contrast. Chromium components determine the difference between red, possibly blue and green - only color differences are conveyed.

It has become possible to connect a source of RGB signals to the TV, which provides the best image quality on the screen of a household TV. Then home computer manufacturers like Atari immediately appreciated this. Amiga. Sinclair and others like them, and after them the still popular game consoles like Nintendo and Sega. Here's your second advantage.

The quality of the transmitted signal is worse than the transmitted video signal, which consists of three components, but is clearly superior to the composite video signal. Convenient connection method, since all video signal components are transmitted over one cable. However, the separation of components interferes, resulting in a decrease in the quality of the transmitted video signal.

Most often used to connect to the antenna socket of the receiver. It is usually used to connect a video camera or camera to a computer. Euro connection diagram with description. It uses 4 shielded wires: two for power and two for differential data signals. Half-duplex differential signaling is used to reduce the impact of electromagnetic noise on longer lines.

The quality of image and sound when supplied via SCART is noticeably superior to the quality of the signal from the RF modulator (once this was the only way to connect to a TV). In addition, the RF modulator cannot transmit stereo sound, introduces noise and requires precise tuning of the TV. Here is the third advantage.

But this seemed not enough, and the developers included additional features in the interface, reserving several “needles” for the future. Since the SCART interface became a standard in European countries (since 1984), it has acquired several new properties. For example, it became possible to control some TV modes via SCART - switch it to “monitor” mode and back, switch to the mode of working with RGB signals. But these possibilities are simple (control is carried out simply by applying voltage). Much more interesting are the other two “needles”, designed to transmit digital data via SCART, which makes the number of commands almost unlimited. Today there are several well-known systems for exchanging information via SCART. This is the Megalogic system used by Grundig. Easy Link from Philips. SmartLink from Sony. So far, their use is limited to communication between a TV and a VCR, but this alone provides opportunities that were previously undreamed of.

Using Easy Link (Philips) as an example, we will demonstrate these capabilities. If you turn on the VCR for playback, the TV automatically turns on. If while watching a TV program there is a need to record it, one click starts recording of that particular program. FollowTV function - the VCR “rewrites” the TV’s tuner settings. It is possible to control the operation of the VCR on the TV screen and automatically select the image format (4:3 or 16:9). At the end of the playing recording, the tape recorder will not only turn off itself, but also turn off the TV. If the TV turns off, the VCR will turn off in a minute. A satellite receiver connected to a TV works similarly. By the way, about the satellite receiver. If the number of SCARTs in a TV depends, as a rule, on its class, then even the simplest satellite tuner has three of them - one for connecting to a TV, a second for connecting a VCR and a third for connecting a decoder of “closed” programs. For the latter, SCART is especially convenient - through it the encoded signal enters the decoder, and through it it returns back in an “open” form. The same is the case with cable decoders of paid programs. In both cases, only one cable is used.

Design.

Let's start with the fact that there are actually 20 pin contacts. The role of the 21st contact is played by a metal screen located around the perimeter of the connector. Its second purpose is to protect contacts from mechanical influences from the outside.

The mating part, the socket, is made by injection molding from plastic. It can have both ears for screws or self-tapping screws, and bosses for installation on a printed circuit board. The design of the cable connectors is not particularly original, but there are at least three varieties that differ in the design of the housing - the cable can be routed sideways, straight, or at an angle. The connector is held in the socket quite firmly by spring-loaded plug contacts. It's almost too strong to be pulled out easily. Yes, and you have to insert it with sufficient caution so as not to move the TV or video.

The quality side.

As is clear from the description, not only audio, but also video and RGB signals are transmitted through SCART contacts. The frequency range of audio channels does not exceed 20-20000Hz. the video signal occupies a frequency band of up to 6-8 MHz, and the RGB channel is capable of reproducing a signal with a bandwidth of over 10 MHz (the frequency band of video amplifiers in a modern TV ranges from 20 MHz and above). If shielded wires are sufficient for audio transmission in most cases, is SCART capable of reproducing lossless wideband video signals? It is known that for ideal matching of a signal transmission line, not only the cable, but also the connector must have certain characteristics (characteristic impedance, capacitance). It's hard to imagine that a multi-pin connector made from ordinary polystyrene has the same frequency characteristics as, say, a coaxial BNC or even the widespread RCA (aka Cinch, aka “tulip”). However, an attempt was initially made to improve the frequency properties of the connector - in SCART, each transmission channel (audio, video, RGB) has its own “ground” conductor, which provides better isolation between signals. But that's all. Any cable bought on the corner, of course, does not reduce the quality of the image to zero, but it does reduce the quality of the image. It uses cheap shielded wire, while to transmit the video signal you need to use a coaxial cable with a characteristic impedance of 75 Ohms. Even a 21-wire cable purchased in a store is a bundle of wires in a common screen.

Speaking about signals transmitted via SCART, we did not mention S-video, which consists of two signals - a chrominance signal and a luminance signal. With the advent of this standard, the ability to work with it also appeared in SCART. For the brightness signal, the “video” channel was suitable, but for the color signal we had to sacrifice RGB, or rather, the “red” channel. This feature is implemented only in those TVs where two SCARTs are installed; in this case, an RGB source can be connected through the second one. But almost always with this connection method a Mini-DIN connector is used.

What should I do?

Especially if in the house only one device has SCART, and the other (others) do not. The solution is as old as time - an adapter or adapter cable. The first are SCART connectors with built-in RCA or S-video connectors.

A tulip-to-tulip or S-video-S-video cable is suitable for them. Adapters can be unidirectional or bidirectional, mono or stereo, with or without switches. The variety of adapter cables is even greater. The most common are SCART-RCA (or “scart tulip”). They also include uni- and bi-directional, stereo and mono, with additional connectors for switching control.

If you need to connect two devices to one device, you can use a SCART splitter for two or three directions. You can find almost any adapter or cable on sale now. Some companies (Sony, JVC, etc.) even sell them bundled with video cameras.

Tips from the Spin Group of Companies.

As is clear from the above, the well-known inconveniences of SCART are still outweighed by its main advantage - versatility. But all its capabilities can be realized only if both connected devices have such a connector. When selecting television and video equipment, do not be lazy to clarify what the existing SCART allows. For example, I was recently surprised to learn that the Thomson 6890 VCR (and a number of other models) reproduces menus on the TV screen only(!) through the RGB channel. To the company’s credit, it came with a “full” SCART. Take every opportunity to improve image quality. Ideally, this is an RGB channel, but not every TV implements it, and a rare VCR can produce such a signal. But DVD can! As for the prospects, SCART is quite capable of holding out for many more years. The key to this is those same two “digital needles”. And only His Majesty Progress knows what teams will appear in the near future and what they will manage.

The Spin group of companies will offer you high-quality audio-video cords with a SCART plug and other cords under the DELINK brand.

Connectors

Most models of TV set-top boxes have a large number of connectors and interfaces. Of course, it would be easier to equip the device with one universal output for convenience, but not every home has a TV, for example, with a modern HDMI interface. Yes, such an output is capable of transmitting video and audio signals as correctly as possible, but such models are not cheap and not everyone can afford them.

Some people still can’t part with their “ancient” TVs, so many TV set-top boxes are burdened with versatility for the sake of convenience. However, before purchasing a set-top box, it would not be superfluous to check whether it has one or another connector/interface for your TV. Also keep this in mind before connecting your TV to the receiver.

Why is it so difficult? But why!

Unlike conventional “tulips”, the SCART RCA connector has a number of advantages that provide extensive control capabilities, better color reproduction and even digital broadcasting, unthinkable in the early 80s (it was developed in 1983).

Today, even consumers who are little educated in electronics know that the variety of colors on the screen is created by only three components: red, green and blue. Their separate supply to the color module eliminates a number of interferences and makes the picture clearer. This opportunity is provided by the SCART connector, in which the 7th, 11th and 15th pins are designed to supply an RGB signal, and the 5th, 9th and 13th, alternating with them, are intended for shielding shells.

But this is not all the capabilities that the SCART connector has. The pinout assumes the ability to automatically turn on and off the TV simultaneously with a low-frequency signal source (DVD or VCR), regardless of which company manufactured the equipment. The widescreen display mode also turns on independently.

In addition to these functions, there are two digital contacts - the 12th and 14th, prophetically identified by French engineers back in 1983, when almost all consumer electronics were analog. There is also a connector for connecting a timer, it is number ten.

So, 20 contacts and one common one (21 in total) - this turns out to be not so much. For modern entertainment video centers they are still sufficient, although they are no longer enough to enable Dolby Surround...

The easiest way to connect a TV to a computer is a video card with a separate TV-out, tulip or s-video.

You can also use a converter.

Perhaps another way to connect your computer to your TV will suit you, for example: - connecting with a vga vga cable, if your TV has a vga input. Some modern TV models are equipped with a special adapter for connecting vga; - connection via a vga s-video adapter. This connection is possible on some models of ATI Radeon video cards, for example, the 3000 series, and with special settings for the video card driver. The TV must also have an s-video input; - connection via a vga YPbPr adapter. The same as in the previous paragraph, but the TV must have a YPbPr component input (three non-yellow tulips); - connection via a vga SCART adapter. The same as in the previous paragraph, but the TV must have a SCART input (comb).

I have a prology hdtv-850wns TV, it has a USB connector, but it’s not an ordinary connector, through it you can send video and audio signals, that is, a signal input... You need a cable for this, but there isn’t one, who knows the circuit diagram for such an adapter ? Or maybe you can tell me which foot to send the video signal to in the diagram? I’m just not good at schematics, so I could figure it out myself...

Thank you, I got the TV with a dead lamp backlight, I converted it to LED from the laptop, but I just want to watch movies on it...

Determining the pinout is a 5 minute question. You need a datasheet for the microcircuit and a little intelligence.

Even though it was a long time ago, did you find the diagram? If yes, please share or link to Ali?

There is also such a TV. I took a Usb cord from an external hard drive, cut off a mini-Usb and at random found a video signal and sound and then soldered it with another cord at the end of which there were tulips.

I have the same principle on Mystery. This USB is just similar to the regular one, but has nothing in common with it. It does not have stereo sound, video tulip and audio tulip. There is no power supply there, the 12V socket is separate.

We know, I almost burned the flash drive

Well... I didn’t write it quite correctly - the connector here is just a real USB, physically, but not electrically))) You can solder anything there, even output 220 for example.

I wrote the same thing))) similar in appearance, inside (electrically) - nothing in common))) p.s. Is the glass half full or half empty? )))).

half whiskey, half cola! )))

Oh, order on Aliexpress and don’t worry... It costs a penny. For example, ru.aliexpress.com/item/1-...Cable-USB/1409419824.html

long wait, I wish I had ordered it

The parcel takes 2 weeks

not two, I order periodically from Ali, and parcels arrive at least 4 weeks...

I ordered the last 6 parcels, they arrived in two weeks, and 6 different ones)

compared Kazan and Baikalsk

in theory, not as long as usb is actually used as just a connector, and has nothing in common with usb itself

not in theory, but it is true. It’s just that the Shanghainese haven’t come up with anything better than adding a USB connector for switching audio and video signals.

Judging by the diagram, the video signal from TWO video inputs (USB pins No. 2 and 3) goes to the 4053 chip (this is a multiplexer/demultiplexer - a switch of digital and analog signals), and there the video input is selected (control contacts No. 9 and 10 of the chip , signal AV12). The sound comes through pin 4, pin 5 is common (GND), pin 1 is (+12 volts). And in the instructions this connector is described as follows: 14. “A/V” connector for audio/video input, additional power supply. To this connector you can connect the included cable with standard RCA type connectors and a power connector: Yellow RCA connector Video input No. 1 Red RCA connector Video input No. 2 White RCA connector audio input Power connector 12 V external contact - negative polarity internal contact - positive polarity

Those who own a significant amount of audio and video equipment are faced with a choice: make it yourself or purchase an adapter from the store that will convert signals of different types. Needless to say, factory devices cost a lot, but you can often do without them. And within the article we will talk about how to make a VGA to RCA adapter. Frequently asked questions will also be answered.

SCART adapter: types and description

After its first appearance, the SCART adapter caused, to put it mildly, mixed impressions among most users. The fact is that such connectors suddenly began to be used on modern televisions or tape recorders, while the vast majority of residents of the CIS countries were accustomed to using standard “tulips”. Of course, today this situation will make many people smile.

It is worth noting the fact that the main reason why the SCART adapter did not become widespread at that time was not even the fact that few people knew about it, but also the banal lack of corresponding cables on sale. Today you can buy any cable product on almost every corner, but in those days their cost was quite high.

The SCART adapter is a 21-pin connector with which users can connect different types of TVs and media devices. After its appearance, this interface won the hearts of most European consumers. Manufacturers of consumer media equipment immediately began using it in their devices. It is worth noting the fact that the developers of this standard were very far-sighted, because their device is still actively used by leading companies to this day.

Just 10 years ago, almost every video or television device that was manufactured for the European market was equipped with at least one such connector. So to connect media equipment to the TV, the user had to buy a SCART adapter. The reason this connector is so widespread is its versatility. Despite the fact that it is provided rather straightforwardly, that is, due to the number of contacts, the interface, although it has many negative aspects, is quite convenient.

First of all, it is worth noting the fact that with the help of one single cable, users can record or play back various video programs. This advantage was immediately appreciated by manufacturers of home computers, and over time, also by game consoles.

It is also worth noting the fact that the quality of sound and image supplied through the SCART adapter is noticeably better compared to the signal from a standard RF modulator. At the same time, we should not forget that the RF modulator does not provide for the possibility of transmitting stereo sound, introduces extraneous noise, and also requires extremely precise tuning of the TV.

Additional features

However, this turned out to be not enough, as a result of which the developers also included a large number of potential features in the interface, reserving space for new functions for the future. Since the time when the VGA-SCART adapter became one of the most popular in Europe, this standard has only just begun to acquire new properties. For example, using this interface today, you can control various TV modes, such as switching it to monitor mode and back, switching the mode of working with RGB signals, and much more. Moreover, these capabilities were previously very simple, while today SCART has the ability to transmit digital data, as a result of which the total number of commands has become almost unlimited.

Today you can find a large number of systems that provide information exchange using SCART, as a result of which the VGA-SCART adapter, as well as many others, have become very popular.

Cool Features

It is worth noting several interesting functions that have become available through the use of this interface.

Once you turn on the DVD player (or tape recorder, as it was originally), the TV automatically turns on as well. At the same time, if while watching a certain television program you have a desire to record it, you start recording this program with a single click. The FollowTV feature gives users the ability to “overwrite” tuner settings from their TV to their media device. It also provides control over the operation of devices through the TV screen and automatic selection of the most optimal image format. After the playing recording ends, not only the player, but also the TV itself turns off, which is also customizable and is a very, very interesting function.

Advantages and disadvantages

Where SCART is used, there is no doubt that the image quality, even color, will be at the proper level. Thanks to many years of engineering efforts, device control capabilities have expanded significantly. Separate (through separate contacts) color transmission guarantees clarity and saturation of the picture. As already mentioned, interference problems have also been successfully resolved, so the TV will operate very stably.

If the pinout is done properly, it will be possible to simultaneously start or turn off the television receiver and auxiliary equipment.

For example, if a tape recorder, video recorder or DVD recorder is connected to the TV, then recording will begin at the very moment when the broadcast is received. It is worth noting the automatic widescreen picture function.

However, even the time-tested SCART has its drawbacks:

• very long cables still unnecessarily attenuate the signal (this is general physics, engineers won’t do anything about it);
• it is possible to increase the clarity of signal transmission only in a shielded (thick and therefore unattractive in appearance) line;
• newer DVI and HDMI standards are often more practical and convenient;
• it is impossible to connect audio and video equipment with modern broadcast standards, including Dolby Surround;
• dependence of the quality of work on the characteristics of the receiver;
• Not all computer video cards, and especially laptops, can process the SCART signal.
