An S video cord is used in video systems that separate the luminance and chrominance portions of a video signal and carry them through separate cables within the S video cable. Composite video has both of these items contained within the same signal. By keeping the circuits separated, the color and picture quality is improved as compared to a composite video signal.
It record the Composite, Left and Right audion and the S-Video signal.
Composite video signals are used with standard definition video. There is no composite encoding system for HD signals. As 720p, 1080i and 1080p are all HD signals, they cannot be carried on a composite signal.
VGA, a computer video output, cannot be converted to a composite (1 video wire) or component video (3 video wires) signal with just a cable. VGA can be much higher resolution than composite video. You will need a scan converter box to create the NTSC video signal.
There are many ways in which one can use a S video to composite cable. The simplest way is by using an adapter if your signal source allows video input.
how can a composite signal be decomposed into its individual frequencies
S-video is a signal format. It is a development used on domestic video systems to improve the quality of images over the composite video format that was the standard interface between equipment. Composite video uses a single wire to carry both the brightness information (Also known as "luma" or "y") and the colour information (known as "chroma" or "c"). Because of the way the colour is encoded in the signal, there is a limit to the resolution of the signal and some vertical lines can appear smeared or softened because of it. S-video uses two wires to carry the signal. One is just for the luma signal or "y". the other is for the chroma content, or "c". S-video is also known as a yc signal because of the two components. Although the colour information is identical to that of the composite signal, the luma signal is a higher bandwidth that composite. The result is that edges look sharper and the image is a slightly higher resolution.
You need a RF modulator to convert the signal to a (RF) TV channel. The audio and video quality will be lower doing this.
A composite signal is a mux or a bus signal. These can be thought of as a collection of other component signals.
In case of TV broad casting, the Video Signal is not transmitted alone, but it accompanied by a number of other signals or pulses, which help the exact reproduction of the picture at the receiving end. These pulses include Blanking Pulses, Synchronizing pulses and Equalizing pulses. A combination of Picture signal and other Controlling signal or pulses is called Composite Signal. Thus Composite Video Signal may consist of Following Parts.Picture information (Data)Blanking Pulses (Delay Pulses)Vertical and Horizontal Synchronizing Pulses (controlling Pulses)Generally,A Combination of Data and Other Controlling Signal is Called Composite Signal .
Composite Video connections are unable to transmit a HD signal. They are on HDTV's for the purpose of connecting older sources, think VCR, that do not have the newer connections like HDMI or component cables.
