3.10 Raw Video Data Output

The TVP5154A decoder can output raw A/D video data at 2× 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 output formatter is responsible for generating the output digital video stream. The YCbCr digital output

can be programmed as 8-bit 4:2:2 or 8-bit ITU-R BT.656 parallel interface standard. Depending on which

output mode is selected, the output for each channel can be unscaled data, scaled data, or both scaled

and unscaled data interleaved in various ways.

3.12 Synchronization Signals

External (discrete) syncs are provided via the following signals:

• VSYNC (vertical sync)

• FID/VLK (field indicator or vertical lock indicator)

• GPCL/VBLK (general-purpose I/O or vertical blanking indicator)

• PALI/HLK (PAL switch indicator or horizontal lock indicator)

• HSYNC (horizontal sync)

• AVID (active video indicator)

VSYNC, FID, PALI, and VBLK are software set and programmable to the CLK 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 shown in Figure 3-4.
