2.5.1 Fast Switches for SCART
The TVP5146 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 TVP5146 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 as examples below. 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.
