2.5.1 Fast Switches for SCART
The TVP5146M2 decoder supports the SCART interface used in European audio/video end equipment to
carry composite video, S-video, and RGB video on the same cable. In the event that composite video and RGB
video are present simultaneously on the video terminals assigned to a SCART interface, the TVP5146M2
decoder assumes they are pixel synchronous to each other. The timing for both composite video and RGB
video is obtained from the composite source, and its derived clock is used to sample RGB video as well. The
fast-switch input terminal allows switching between these two input video sources on a pixel-by-pixel basis.
The fast switch is a hard switch; there is no alpha blending between both sources.
