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 TVP5150AM1 decoder can output raw ADC 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)

• INTREQ/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)

The position and duration of the HSYNC, VSYNC, VBLK, and AVID outputs are I

C programmable,

providing control of synchronization timing relative to the video output.
