3.13 Raw Video Data Output
The TVP5150 device can output raw A/D video data at 2x sampling rate for external VBI slicing. This is
transmitted as an ancillary data block during the active horizontal portion of the line and during vertical
blanking.
3.14 Output Formatter
The YUV digital output can be programmed as 8-bit 4:2:2 or 8-bit ITUR BT.656 parallel interface standard.
