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. If 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.

2.5.2

Separate Syncs

VS, HS, and VBLK are independently software programmable to a 1

× pixel count. This allows any

possible alignment to the internal pixel count and line count. The default settings for 525-line and 625-line

video outputs are given in Figure 2-14 and Figure 2-15. FID changes at the same transient time when the

trailing edge of vertical sync occurs. The polarity of FID is programmable by an I2C interface.
