Digital Processing
Figure 2–2 is a block diagram of the TVP5040 digital video decoder processing. This block receives digitized
composite or S-video signals from the A/D converters. It performs Y/C separation, Y, and U/V signal enhancements.
It also generates horizontal and vertical syncs. The Y and U/V digital outputs may be programmed into various
formats: 20-bit, 16-bit, 10-bit, or 8-bit 4:2:2, and 10-bit or 8-bit ITU-R BT.656 parallel interface standard. This block
also retrieves VBI data and stores it in a FIFO. The data from the FIFO can be read either through the host port or
output as ancillary data on the video port.
