HENGSHENG 25cm S-Video 4-Pin to 3-RCA female RGB Component Cable Adapter 4-Pin Mini-DIN S-Video Male to 3 RCA Female Cable for DVD.DVD, TV/HDTV, VCR's, CD players S-Video 4-Pin DIN,separate the output brightness and chroma, to avoid mixed video signal output when the brightness and color of mutual interference. And S-terminal to separate the two signals, this will not have to turn the brightness of the signal into low-pass filter. This can give the brightness of the signal has a greater bandwidth, but also solve the problem of signal overlap. As a result, the interfering lattice signal is excluded. The RCA interface enables the separation of audio and video transmissions, which avoids the degradation of image quality due to audio / video mixing interference. Almost every audio and video device provides such interfaces for audio and video input and output.<br>
