got it with my graphics card the other day.



Is it something i can be using, i know its similar connections to my tv and ps2

 

Looks like an S-Video to Red Green Blue ( Y/Pb/Pr input ) to watch from your PC on your TV (if the TV has proper composite/prog scan inputs.

 

actually just had a look at tv and its white yellow red, so maybe i was wrong

 

White and Red are sound, yellow is s-video.

That is for a slightly different connection on your tv m8, does the same thing, but better quality I think

 

Thats what i thought dan but whats green and blue for on that cable then?

 

red greeen blue are all video. It's a far better quality connection that scart, s-video or the yellow RCA (which is single video) that most TV's and video's have.

Some TV's do have RGB rca plugs on them, and lots of DVD players have them, and I think it a something to do with progressive scan aswell. The idea is that it only carries video signal, and there are three video connections, each one carrying only a major colour group, rather than scart or s-video which carries all three together, along with audio (in scart), or componant (which is the red + white audio RCA's and the yellow (single) video RCA...

 

ahh right, all is clear now

 

And the red RCA on that plug in your picture isn't audio. All three of those are video

Here, this might help

S-VIDEO



Separate video, abbreviated S-Video and also known as Y/C (or erroneously, S-VHS and "super video") is an analog video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one package. S-Video works in 480i or 576i resolution

Componant Video
(RBG, Y Pb Pr)



Component video is a type of analog video information that is transmitted or stored as two or more separate signals. Component video can be contrasted with composite video (such as NTSC or PAL) in which all the video information is combined into a single signal such as a TV broadcast. Currently, component video connections are gradually being superseded by the higher quality digital DVI and HDMI interface.

Analog video signals (also called components) must provide red, green and blue signals to create a television image. The simplest type, RGB, consists of the three discrete red, green and blue signals sent down three coaxial cables. There are a number of schemes which vary according to how synchronization is handled. If a synchronisation signal is sent on the green channel, it is called sync-on-green. Some schemes use a separate sync channel, for instance the European SCART connection scheme in which the video signal occupies four (R,G,B + sync) of the 21 pins in the interface. SVGA, another RGB scheme, is used worldwide for computer monitors (this is sometimes known as RGBHV, as the horizontal and vertical synchronisation pulses are sent on separate lines).

Component video is capable of producing signals such as 480p, 720p, 1080i and 1080p, but digital connections such as DVI (video only) and HDMI (which can also include up to 8 channels of audio) give better results at the higher resolutions (up to 1080p). HDMI also includes both a video and audio signal in a single cable.

SCART




SCART (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a French-originated standard and associated 21-pin connector for connecting audio-visual equipment together. It is also known as Péritel (especially in France, where the SCART word is not normally used) and Euroconnector.

SCART makes it easy to connect AV equipment (including TVs, VCRs, DVD players and games consoles). In essence, it gathers together various common analog signal-types into a single connector. Previously, each of these would have had their own socket, requiring numerous separate connections (and a "spaghetti"-type mass of leads). The signals carried by SCART include both composite and RGB video, and stereo audio input/output, as well as support functions.

In Europe, SCART is the most common method of connecting audio-visual equipment together, and has become the standard connector for such devices (even more so than the phono plug). It is far less common elsewhere in the world.

The official standard for SCART is CENELEC document number EN 50049-1.


Composite Video/Audio



Composite video is the format of an analog television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier. It is usually in a standard format such as NTSC, PAL, or SECAM. It is a composite of three source signals called Y, U and V (together referred to as YUV) with sync pulses. Y represents the brightness or luminance of the picture and includes synchronizing pulses, so that by itself it could be displayed as a monochrome picture. U and V between them carry the colour information. They are first mixed with two orthogonal phases of a colour carrier signal to form a signal called the chrominance. Y and UV are then added together. Since Y is a baseband signal and UV has been mixed with a carrier, this addition is equivalent to frequency-division multiplexing.

Excellent thanks for the info mate

That last plug is what i use to connect my ps2 and jvc tv together

 

Pretty much everything these days has Composite connections (Yellow, Red + White) and is also known as "AV" connections (a lot of camcorders use that, and you will find most TV's have composite inputs, as do lots of VCR's. Most DVD players will have composite out and scart out as standard, and more and more are getting Y Pb Pr (RGB) outputs aswell
