Converting composit to S-Video Under Hot New Products, choose C2SX RCA to S-Video Here’s a $30 way to solve the complexity of switching multiple format video sources through an audio/video receiver. the C2SX converts each video source’s composite output, usually the yellow RCA connector, to S-video. When all of the sources into your A/V receiver are S-video, the only connection you need to your TV or monitor is the single S-video cable. C2SX is a passive unit (no external power) that splits the composite signal into the two parts, luminance (lightness and darkness) and chrominance (color), which make up the S-video signal. I saw this advertisement last night. Will it work without any signal degradation? IF it does, then would this eliminate the need for receivers with "up conversion" capabilities?
