IDID1:
Bit 0/1 = Transaction video line number [9:8]
Bit 2 = Match 2 flag
Bit 3 = Match 1 flag
Bit 4 = 1 if an error was detected in the EDC block; 0 if not
CS:
Sum of D0–D7 of DID through last data byte.
Fill byte:
Fill bytes make a multiple of 4 bytes from byte 0 to last fill byte.
3.10 Raw Video Data Output
The TVP5151 decoder 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.
3.11 Output Formatter
The YCbCr digital output can be programmed as 8-bit 4:2:2 or 8-bit ITU-R BT.656 parallel interface
standard.

3.12 Synchronization Signals
External (discrete) syncs are provided via the following signals (see Figure 3-5 and Figure 3-6):
VSYNC (vertical sync)
FID/VLK (field indicator or vertical lock indicator)
GPCL/VBLK (general-purpose output or vertical blanking indicator)
PALI/HLK (PAL switch indicator or horizontal lock indicator)
HSYNC (horizontal sync)
AVID (active video indicator) (if set as output)
VSYNC, FID, PALI, and VBLK are software set and programmable to the SCLK pixel count. This allows
any possible alignment to the internal pixel count and line count. The default settings for a 525-/625-line
video output are given as an example.
