DIGITAL VIDEO INPUT FORMAT

Video data enters the encoder on pins PD[7:0]. The encoder accepts and processes digital video data in

accordance with CCIR 656 and CCIR 601 standards. The input data are 8 bit multiplexed CbYCr component video,

encoded in the 4:2:2 format. The input bit stream may contain End of Active Video (EAV) and Horizontal Ancillary

Control (HANC) codes. The relationships of the digital video with analog timing are show in Figure 3.

CCIR 656 Timing Relationship Between Video Data and The Analog Sync Waveform

The digital active line begins at 244 words (in the 525-line standard) or at 264 words (in the 625-line standard) after

the leading edge of the analog line synchronization pulse, this time being specified between half-amplitude points.
