This signal is then bandwidth-limited to comply with requirements for broadcasting. The phase and amplitude of the signal represent the two original signals. The first step is to combine the Pb and Pr to form the C signal, for chrominance. To recover the original RGB information for display, the signals are mixed with the Y to produce the original blue and red, and then the sum of those is mixed with the Y to recover the green.Ī signal with three components is no easier to broadcast than the original three-signal RGB, so additional processing is required. Once the Y signal is produced, it is subtracted from the blue signal to produce Pb and from the red signal to produce Pr. This signal closely matches a traditional black and white television signal and the Y/C method of encoding was key to offering backward compatibility. The first of these signals is called Y, which is created from all three original signals based on a formula that produces an overall brightness of the image, or luma. The image is originally captured in RGB form and then processed into three signals known as YPbPr. Standard analog television signals go through several processing steps on their way to being broadcast, each of which discards information and lowers the quality of the resulting images.

However, S-Video did not get widely adopted until JVC's introduction of the S-VHS (Super-VHS) format in 1987, which is why it is sometimes incorrectly referred to as 'Super-Video.' Before the shift towards digital video the S-video format was widely used by consumers, but it was rarely used in professional studios where YPbPr or component was generally preferred. The Atari 800 was the first to introduce separate Chroma/Luma output in late 1979. Although it improved over composite video, S-Video has lower color resolution than component video, which is encoded over three channels. It also eliminates several types of visual defects such as dot crawl which commonly occur with composite video. It encodes video luma and chrominance on two separate channels, achieving higher image quality than composite video which encodes all video information on one channel. S-Video (also known as separate video, Y/C, and erroneously Super-Video) is an analog video signal format that carries standard-definition video, typically at 525 lines or 625 lines. However, the shield is often absent in low-end cables, which can result in picture degradation. The shells should be connected together by an overall screen/shield.
