Video appearances: types of roses. What is smugha

Hello everyone again)

I'm talking about the PSOne prefix.
Last time I rozpov_v about the drive for tsієї prefixes.
Well, as we have a working prefix, you need to take a picture on the television.
Know for her reference SCART RGB cable.
About new and other cables and will be rozmov.
UPD: to the point, this cable is not only a good picture, yes, one more function works with it)))

I wanted to take a look at the image on the TV set-top boxes.
The set-top box was connected via a composite audio-video cable. And even though it looked normal on the old TV set, it didn’t look good on the new one - the picture was spread out and tremt, the colors were not so good.

Even more often climbing on the eyes of such a cable, component video.

Ale before buying virishiv read on the forums, scho yak. I'm not a gift.
Playstation 1 consoles cannot use component video. Tsey cable is less for PS2.
For PS1 options are as follows:
-composite audio video cable (highest option)
-
-SCART RGB cable (best choice for PS1)

S-Video happened to be out because there is no such entrance in my TV. It is possible only through the connection, but it is not known that at the output of this adapter you will be able to transmit a composite signal.

SCART RGB didn’t know everything in a moment, they were traipsing like crazy, but with even more expensive delivery, not from China.
І, so, if a SCART cable for Playstation transmits an RGB signal, it transmits only composite video and sound. Please read the product description carefully.
І axis nareshti menі got the required cable from delivery from China.
The seller saw the number for a check.


And the axis is the cable itself.





The cable is not too soft. There is no writing on the cable. There are no ferrite filters.
Connecting, without inserting a disc, starting the prefix.
If the connections via the composite cable had to be switched manually to the composite video, then the SCART cable will switch the TV itself to the SCART input, as soon as the set-top box is turned on.
Riznitsyu pobachiv already on the exciting screen.


No, not the hand trembled, the camera standing on a tripod, the picture is left-handed - ce і є rozmozhennya z composite cable.
The breeze was especially drawn, as a good boulo can be seen across the text.
More photos.
Composite:

RGB:


It’s good to see that the colors have become succulent, the picture is clear.

Well, that's all, thank you for your respect, we have good luck, we have for now

In this hour, there are impersonal different video standards and interfaces. Some vicorists have been victorious for more than a dozen years, otherwise they are less likely to enter our daily life and in this diversity it is easy to get lost. It's so self-folding, like nefahivtsev rozіbratisya in templates for the forum. In this article, we have developed a small selection of different interfaces for transmitting a video signal, as well as wider video connections.

Let's hope that this information will appear to you as a guide.

Composite Video Video

Composite video of the destinations of the transmission over one dart of all warehouse video signals in a mixed view.

Sound the composite socket or the yellow RCA socket, or the universal universal socket SCART. For the transmission of a composite video signal, a coaxial cable with RCA sockets ("tulip") on the ends is used.

Composite video signal ( composite video) vikoristovuєtsya more for hours of video cassettes, but not the building to transmit a high-quality signal. For reasons of guilt, only in inexpensive video equipment, for example, in televisions with a small screen diagonal (14 "-21").

Component video guide

Component video signal is also called color. Vіn vengeance signal of brightness (Y) and two color signals (U і V), which are assigned to the formula:

Y = 0.299R + 0.587G + 0.114B

For visualization of the image, the superimposition is superimposed ( interlaced) or progressive ( progressive) rosacea. The cross-cutting of the rosette zastosovuetsya in all the basic systems of televised movement. Progressive scaling zastosovuetsya at the current TV standard HDTV and at the current DVD-programmers, the scallops allow you to take a higher quality of the image.

To transmit such a video signal, three different coaxial cables are used, on the ends of which there are RCA ("tulip") or BNC sockets.

S-Video video

The S-Video socket should be played for video signal display from video cameras, PCs and game consoles on other TVs and other video equipment. The S-Video interface has two signal lines – color signal (C) and brightness signal (Y). When vikoristanny in quality dzherela signal of a DVD player or a satellite receiver and a TV set with a diagonal of 25" this interface allows you to receive a larger picture, a lower composite video signal.

Cable for transmission of this video signal with different types of sockets: 2 BNC sockets, 2 RCA ("tulip") sockets, 4-pin Mini DIN socket or universal SCART socket.

Video Video RGB

To transfer the color image to the EPT-monitor, RGB skin color intensity signals are used, as well as horizontal (H) and vertical (V) flashing signals. The sum has five signals - RGBHV.

To transmit the RGB signal, 5 coaxial cables equipped with BNC sockets are used.

VGA video video

VGA sockets, RGB signals and synchronization, also called DDC signals for transferring information between a video card and a monitor. The VGA cable is connected to an optional D-Sub 15-pin connector (also called D-Sub 15 pin).

DVI video

DVI digital video is more important in video adapters of personal computers. It ensures that the signal from the digital form is transmitted directly from the video adapter of the computer or laptop to the projector. With this, the digital-analog image is not broken (as in the S-Video standard or the composite video signal), which allows you to capture a picture of higher quality.

For today's hour, there are two different versions of the DVI rose:

• universal combination of roses DVI-I. Vіn allows you to connect both digital and analog monitors (for the presence of an adapter from DVI-I to 15-pin VGA D-Sub);
• I will renew digital roses DVI-D to which you can connect only digital monitors. Such a rose is seen in the rose of DVD-I in the daytime which opens (contacts) in a horizontal slot. As a rule, such an interface is rarely found on cheap video cards.

In addition, the difference between DVI (DVI-I and DVI-D) may have two different versions: single linkі Dual Link, which are considered by the number of contacts. At the same time, all 24 digital contacts are broken in Dual Link, while Single Link has less than 18. Single Link can be found in outbuildings with separate buildings up to 1920x1080 (the so-called HDTV). For great permissions, Dual Link is already victorious, which allows you to increase the number of pixels to be displayed.

HDMI video

HDMI interface ( High Definition Multimedia Interface) applications for connecting to DVD players, satellite receivers and video adapters for personal computers, modern TVs and home audio theaters. Today, it is the standard for the transmission of digital audio and video in compressed form.

HDMI is an older digital digital format that allows you to transmit not only high-density video, but also anonymous digital audio channels, using only one cable. An HDMI cable with a signal spectrum width of up to 10 Gb / s allows you to not only display a video signal of a high density, but also simultaneously transmit up to eight channels of a high-density audio signal.

The HDMI interface is a further development of the DVI-D interface and more information about it, but more detailed parameters.

In this hour, the next time, see HDMI sockets:

• Type A, which has 19 contacts and the largest possible width.
• Type B, which can have 29 contacts. This extension has a video channel that allows you to transmit video information from a separate building in 1080p. In this hour of roses, there are no more requests.
• mini HDMI extensions for video cameras and portable devices. Vіn є varіatієєu HDMI Type A, аlє mає zі zіnshennymi rozmіrі.

It is necessary to pay attention to those that the HDMI cable cannot be longer than 15 m.

To accommodate all the descriptions above the standards in order of increasing video signal quality, then we take:

• composite video
• S-video
• component video

Switching video part to the complex

Let's continue the rose. In this article, there is a question about the switching of video signals between dzherelam and outbuildings (outbuildings) of vibration. Also, the types of video signal transmissions will be considered and, obviously, the problem of preparing self-contained cables.

Cables

Actually, regardless of the type of analog video signal (composite, S-Video, RGB, component), constructively the conductor is a coaxial cable with a 75 Ohm support. Depending on the type of video signal, there may be only one such cable, or a splice of such cables is used to transmit the signal.

Tim is not smaller, but there are many different practical implementations of this design. The central conductor can be a solid copper monocore, it can be composed of faceless thin coppers or copper wires, and so on. The screen can be alone, folded and folded, can be stacked with a dart or a dart in one with foil or foil plastic. The cable itself can be meaningful and thin, or it can be thin and inconspicuous. Zagalom, there are a lot of options here. And most importantly, singly, as the design itself is safe, it is guaranteed to have a high clarity of the image when transmitting an analog video signal, it is easy to finish it - the skin cleaner has its own methods and patented technologies. Deyakі primudryayutsya robit miraculous cables, scho folded only from a rich-core copper conductor and one copper screen. And it’s worth making a super-tricky cable from the cost of expensive materials, and the quality of the image is not true, it’s safe to say that such a cable is worthless. So, when choosing a cable, turn on the "image factor", blindly trusting the phrase "expensive - it means fine", not varto in the same time. However, not everything is so scary, the shards of most of the "cable makers" can still fully deserve the reputation of a total maker, which means that if you buy a cable from a rated maker, which, having recommended yourself well with the right cable maker, you will hardly have mercy. Accept, better, lower, buy the cable of an unknown picker, which, according to the words of the seller on the market, “is richly cool for all these fashionable brands.”

And why can you want to use a few examples of re-wired video cables?

Supra, Wire World, Straight Wire, Canare, Monitor cable, QED, Ixos, Liberty. I realized that this is not a list, but "on random" brand names. Guessing, as you know, far from all ...

Typical methods for transmitting an analog video signal

Composite

Most of the most affordable video equipment and budget-class televisions, the widest among the people, while there is still a way to transmit a video signal, all warehouses are transmitted from a different source via one single coaxial cable. Such a video signal is called "composite video". Even in the era of VHS cassettes, such a method of transmitting a video signal can be considered quite acceptable for clarity, shards and the VHS cassette itself (paired from DVD, for example), cannot boast of a high-clear image, then with the advent of inexpensive DVD-players the video signal, even if it’s not a sentence for death, then, having begun to go to the back door, go to the class of budgetary equipment (the expensive second-hand video equipment has not been victorious for a long time). Now composite video output may be less than VHS-player/tape recorder (there is no such thing as composite, other low-frequency video output), and karaoke consoles. It is important to have more other attachments, such as DVD-players, modern video cameras, satellite receivers and so on, there may already be more video outputs, where video signals are transmitted only one to one. If, and in the majority of the current outbuildings, a composite video monitor, as before, present, so as not to allow the possibility of connecting the device to the "less protruding" outbuildings, it is possible to switch the device on. For example, a lot of current TVs with small diagonals to the screen (14″-21″), no matter how earlier the models were released, just like before, only a composite video is possible.

Sound the output and input of the composite video signal to look at the RCA jack of the yellow color (in the photo it is pink in the lower left corner), or it can be transmitted through the universal.

The cable that is used for transmitting a composite video signal is 1 coaxial cable with RCA sockets (“tulip”) on the ends.

S-video

This type of video signal ensures separate transmission of the signal brightness (Y) and two combined signals in color (C) by independent cables. The standard for this type of connection is a round 4-pin rose. S-Video transmission can be arranged via Scart

When paired with a composite video signal, connecting via S-Video, it ensures a certain win in the clarity and stability of the image, less in the world - in color transmission. However, qi polypshennya will be remembered less when using a high-quality dzherel (DVD-player, yakіsnogo satellite receiver only) to the large diagonal (25″ and more) in front of the screen. With a TV screen diagonal of 21″ (and less), the difference between the composite video signal and S-Video may be obvious, but the shards are already richly deposited in the quality of the TV itself.

Component

Otherwise, the name is color-variable (Y "PbPr, or in a different way YUV, YIQ). For the transmission of warehouse vicor, three independent coaxial cables are used, de one cable (Y) is used for signal transmission at spivvіdnosnі 0.299R + 0.5876G + 0.114V, in the second (Pr) - red minus bright (RY), and on the third (Br) - blue minus bright (BY) RCA or BNC.

And the axis will sound like a component video of the DVD-programmer.

The brightness of the picture when connected by component is radically (more beautifully) changed in S-Video and more so in the composite. Here polypshennia can be clearly seen: the picture is clear and stable with accurate color reproduction. Particularly obvious will be the advantages of a component connection with the use of a low-powered video signal and large screens (TVs 29 "-36", good plasma panels, projectors with a large screen).

RGB

In this way, there is a separate transmission of three primary colors and a synchronization signal. To be precise, the type of video signal is called RGBS (Red, Green, Blue, Sync). The transmission of information is carried out behind independent cables. You can use 3 or 4 other coaxial cables (there are 3 cables in a row, the sync signal is both green and green) with roses RCA or BNC or RGBS can be transmitted via .

It also uses a foldable variety of RGB, so for the transmission of signals, not 3 or 4, but 5 cables are used, the horizontal and vertical synchronization signals are transmitted only one to one. This variety is called - RGBHV (Red, Green, Blue, H-Sync, V-Sync). The Scart cable cannot transmit RGBHV, the oscillators for such a video signal sound vicorous around the coaxial cables with roses RCA or BNC, but one VGA cable(from one side of which you can also use BNC roses (pictured)).

To the point, the RGBHV itself is used to transfer the signal from the video card of the computer's system unit to the analog monitor - marvel at how much the picture is clear, readable and stable.

Frequently Asked Questions

How can you change the most important standards for transmitting an analog video signal for image clarity?

In descending order:

• composite video
• S-video
• component video
• RGBHV

  Ale tse in that way, as if abstracted from practical implementation. Wanting, obviously, a component or RGB for a better layout, lower S-Video or more, composite. And the axis between the i RGBS (Scart) component is different, like the picture is often small. Quite often, the component connection seems to be optimal, but as it was said, RGBS sound is realized through Scart, as a conductor, which can be waived by the coax, we will put it in the component cable. Until then, Scart is not too old, but it is often necessary when, say, mounting a projector on a wall or installing a stand with equipment far from a plasma panel or a TV. Well, come on, there are a lot of plasma panels and Scart projectors simply not possessed.

  And RGBS via Scart will be the best solution for connecting, say, a DVD player to a close-fitted TV with a large screen or a plasma panel - 4 BNC or Scart - 4 RCA).

  So, the options (component video and RGBS) ensure even higher clarity of the image, just the skin option is convenient for the singing vipadkivs (to keep the minds of the installation of the possession and the commutation possibilities of the possession). Ale, you have been poturbating the connection of a high-class projector to a high-class DVD-player, and for the increase in the brightness of the picture, you plan to vikoristovuvat and scaler tezh, then here you can also marvel at the bik RGBHV, or go ahead and speed up the digital connection (SDI or DVI)
  

  What about converting RGB to component video or back?

  Yes. However, the price for such an extension is too high, so it’s easier to choose a dzherelo (DVD-player, satellite receiver, etc.) and an air conditioner (TV, plasma panel, projector), so that you can connect them without any changes.
  

  Chi є converting S-Video from composite video or back?
  

  In times of transformation of a composite signal in S-Video, you no longer solve the problem of the consistency of switching attachments - the clarity of the image of such a transformation is not enough. Often, these are converted into S-VHS video recorders, or high-class AV receivers. Traplyayutsya and okremі outbuildings.

  When converting S-Video to a composite signal, you remember to use it like a picture. True, for small screens (14 "-21" diagonally), this problem is practically not relevant. You can make such a transformation yourself for a sprat of khvilin:

  

  
  

  How does the S-VHS cable look like S-Video?

  S-VHS is not a cable, but a video cassette format. The cable has one name - S-Video, although, unfortunately, sellers at rich stores call it S-VHS, which is less evidence of their incompetence.
  

  Why talk about the presence of the Scart rose on the TV?

  Ni. On the right, the fact that a composite video signal, і RGBS, і S-Video can be transmitted through Scart. Plus to tsgogo, the sound of that service team. Therefore, it is not obov'yazkovo, that in the Scart-output of the device or the Scart-input of the TV set is RGB. The answer is simple: look at the instructions for the device. Or to conduct a visual inspection of the rear panel of the device: often write Scart (RGB) above the Scart rosette. Vtіm, write not zavzhda, but the axis in the instruction is the information about the language.
  Detailed information about Scart roses can be taken from . However, I can rest easy: maybe all current TVs of great diagonals, as well as have Scart roses, one or two of them will definitely be RGB. If you need DVD players, then maybe all current models with Scart allow you to play through the new RGB. Ale better to clarify, about every fluctuation.

  I have more than one Scart with RGB on my TV - who should I tell you: a DVD player or a DVB satellite receiver (say, NTV +)?

  If the picture from the satellite receiver is not available in HDTV format (high-definition television), then RGB is more likely to connect a DVD player, and the satellite receiver - via S-Video. Karaoke and VHS-videomangitophone - behind the composite, zrozumilo.

  Why not damage the image quality to the video signal through the AV receiver?

  The switches of most modern AV-receivers in the house of their receivers do not introduce visible transitions to the video signal. Tim is bigger, which in most cases is the most likely to cause a video signal (most people have a DVD player) to sound connected to a TV (plasma panel, projector) without a middle. Switching through an AV receiver is often less than composite video signals and S-Video.

  Which S-Video cable should I buy?

  If a cable is required for connecting an S-VHS video recorder or a reasonably inexpensive satellite receiver (say, NTV +) to a TV set with a screen diagonal of up to 29 ″, then you can safely combine an inexpensive cable for $ 10-15 (for a ready-made start-up cable, 0.7-1 5 meters). If you have a classic TV with a large screen, to which you want to connect, say, a DVD player (with no RGB, no component connection is not available for your device), then you can turn the power on the black cables for $ 25-40 Also, the quality of the cable may not be significant, so you need an S-Video cable with a length of over 4-5 meters.

  Which scart cable to connect the RGB DVD player to be used?

  To connect to a 21"-25" TV set, it's enough to have an inexpensive cable for $15-20 (Hama, Monitor Cable, Bandrige, etc.). If you have a decent TV with a diagonal of 29″-36″, then it is better to buy a cable with a class no lower than Profigold PGV-78x. Such a cable is more taut for 35-50 dollars. For great plasma TVs, let's look at serious cables like Supra, QED (in the picture in the RGB description in the middle of the article), top models like Monitor cable and so on. Such a cable will cost $50-100.

  What component cable to take?

  To connect a projector to a DVD player, it is better to use a component cable, which costs $100-150 (for 2-3 meters). To connect a DVD-player to a projection or stellar TV, whether it's diagonal or not, it's enough to buy a component cable for $30-50 (2-3-meter length). Although the most optimal solution would still be independent preparation of the cable, or preparation for the installation of such a cable in some great professional store. To get such a component cable (2-3 meters of a winder) at once from roses at a cost of $30-60. I have already described the benefits of buying professional cables, but I will repeat: buying a cable from a brand you pay not only for the product, but also for advertising in glossy magazines, packaging and, arguably, more than the name of the picker. In connection with component cables, the problem of overpayment of pennies is especially relevant, which is why it is often necessary to wind up a cheap component cable, splitting from 3 identical pieces in a good antenna cable and 6 roses (the total variability of the cable in stock is not more than $ 10) will show no more than for firms. for $50. Obviously, there are inexpensive LCD-projectors, plasma panels, projection or kinescope TV. On yak_snih plasma panels or high-class projectors with a large screen, such a “focus” is not possible with a cable.

  How to install a yakіsny component cable yourself?

  It is necessary to buy a black coaxial video cable ($2-4 per meter) and 6 sockets of the required type (RCA or BNC) in a professional equipment store. However, the situation is such that practically all current RCA or BNC roses for professional use are not suitable for soldering, but are connected with a cable with a special tool. Most professional shops provide service for roses - the price is about $1 for leather roses. And if you prepare a component cable for a cut cable for 3 equal shreds and install roses, then, please, for the work of preparing a component cable, you will take a total of $6; Obtiskni roses themselves cost $3-5 per piece (high-class metal roses with a 75 ohm fluted support). Axis and pay attention: if you need a 3-meter component cable, it will cost about $50-60 at the same time with the robot and roses. And such a cable, turn, for the clarity of the picture, it is easy to “compare” with a purchased branded component cable for a couple of hundred dollars. I'm not kidding. Before speech, at serious installations of home theaters on the basis of good projectors, a professional video cable sounds and is installed, and not a Hi-End video cable “split” at a box made of red wood. Of the most popular companies that manufacture professional video cables, I can name, for example, a Japanese company, but I don’t want to draw other leading manufacturers of professional cables, for example, to describe the self-manufacturing of cables on the butt of Can. It just so happened that I didn’t often win Canare in installations, and at home - fix these cables for me. Also, for the preparation of a component cable, you can twist Canare cables or wind them. To the point, such cables allow, without visible losses, like little vicorists to wind a dozen meters from a sprat.

  

  Can you make an S-Video cable yourself?

  The scheme is the same: buying a yakіsnogo professional cable (I'm guessing, you need two coaxes) and a bet of S-Video roses. You can find the soldering of the cable in the middle of the article. And then get ready: soldering roses with S-Video is not easy to do. It is better to take a cable that is thin, otherwise it will be more foldable to solder it to the pin of the rozn_manya.

  Know, self-preparation of S-Video has more minuses, lower pluses, safe low quality of the video signal over S-Video, soldering flexibility and low price of S-Video cables, the quality of which is sufficient for the switcher's HS-VBODE connector of the satellite
  

  Can you make your own Scart?

  Yakshcho you have a lot of patience, so. Why be patient? , you will have to solder 21 contacts from the skin side. Just what is needed? No need. What does a home theater need for Scart? That's right, video signal transmission, and often only RGBS and composite (the sound is all the same through the home theater audio system) - but it’s already a lot less trouble. Here you need to buy a couple of good Scart roses ($ 3 -10 pieces) and a cable, class Canare V5-1.5C (pictured), which costs a lot of dollars per meter, but you can have 5 thin coaxial cables with a flexible support of 75 Ohm. .

  

  The result is such a self-contained Scart for $30 for the clarity of the picture in S-Video or RGBS mode can easily compete with the purchased Scart for $70-100.
  

  What is the maximum length of a component, RGB (at least 3-5 coaxial cables) or a composite cable?

  Shards in all types of vikoristovuyutsya okremі coaxial cables, you can talk about all three kinds of zadnannya at once. Since, as well as victorious coaxial cables (including professional ones), then without visible image deterioration it is possible to vicorize up to 20-30 meters, and with bazhannі more. On low-yield cables, images can become noticeably higher even for a longer cable over 5 meters.
  

  What is the maximum length for an S-Video cable?

  Most often, inexpensive ready-made S-Video cables are not equipped with the best coaxes, it’s not good to behave on small lengths, but if you want to stretch the cable more lower by 3-5 meters, then it’s better to buy a low-frequency (to be expensive) S-Video cable, otherwise, work it out yourself with a professional video cable (it will be cheaper and better) - you will not be a problem for someone who has a fall of a dozen or two meters.

  Go ahead…

Blue, green and red. Others come out with the change of three main ones. This principle is called RGB. Video cameras generate images in this format, and then the signal is reflected by a TV set or a computer monitor. By changing the intensity of the three main colors, you can create any kind of spectrum, and as a result, natural images appear on the screen.

What is the smuga omission?

Blame the power: "Who did you see the transmission of the video signal to?" For whom it is possible to select the RGB format without intermediary, prote wines occupy even a wide frequency range. Therefore, it is best to translate such a signal into a compact format, which can be transmitted via a component cable. This format will be from three signals. The first one is called the impulse of brightness, moreover, the building's wines carry black and white information, which is reflected in the original RGB. The other and third signals are called color-various. The stench exudes a piece of red and blatant brilliance. Mathematically, the color-variable pulses are similar to the RGB-signal. The component cable does not transmit a bright color to a part of the green color. It will be counted by the meanings of other signals, even if the meanings of bright blue and red colors. Otzhe, the part that was lost, falls on the greens. The component cable for the transmission of a video signal reduces the frequency range by one third of the original one.

Decommissioning the component video format?

Tse koduvannya vykoristovuyut pіd hour transmission і izobrazhennya, vіdomogo yak DVD-standard. Almost all DVD-players are capable of video input, up to which a three-wire component cable is connected, which ensures cleanliness and rich colors, as well as image clarity. Most of the time, the engravers can use a small number of different types of video outputs. However, the choice of such interfaces has been developed to the point where, for the quality of the component video, it can be compressed and transmitted in the highest standard (for example, composite) to the monitor. Therefore, if your player and TV set are built to work in component video mode, it is better to override the standard itself. As a rule, such a cord is made up of three roses of the RCA type, which are denoted by chervonim, green and blue colors (Y, B-Y, R-Y). Like a TV set and a monitor, the same type of roses can be used, but it is important to trim the color marking. Most receivers accept a component signal through the VGA port. This interface is equipped with a 15-pin D-sub-socket.

Such a cord is let out by the usual pickers.

PS2/PS3 component cable

This cord is used to connect to a PlayStation2 and PlayStation3 TV. PS3- and PS2-component cable for viewing pictures, the cost of which is 576 r when connected to the PlayStation2. And with the connection of the PlayStation3 system, the building is different - up to 1080 rubles. Such a component cable is compatible with the majority of TVs, which supports the incoming rose standard. In addition, the cable can have two connectors for direct connection to the sound of the audio channel. The component cable is used as one of the shortest interfaces for connecting the gaming system to the TV and is only delivered to the HDMI standard.
