Note: When the GV7704 is receiving HD-VLC encoded HD video formats at "true" 30 or
60 frames per second, the 270Mb/s serial data rate will be at 270 x 1.001 Mb/s. This
multiplication factor is to account for the fractional increase in the original HD video
frame rate. For all other HD frame rates, the HD-VLC encoded serial data rate will be
exactly 270Mb/s.
4.7 Ancillary Data Extraction
The GV7704 is capable of extracting ancillary data packets, with the type of packet
specified by the user on a programmable 10 bit DID. The 2 MSBs of the DID are written
to ANC_PACKET_DID_9_8 in register ANC_PACKET_DID_9_8_REG, and the next 8 bits
are written to ANC_PACKET_DID_7_0 in register ANC_PACKET_DID_7_0_REG.
Up to 16 User Data Words can be extracted per ancillary data packet. The chip will
extract the DID-SDID/DBN-DC-UDWs-CS bytes, and they are available in 10-bit pairs
(ANC_PACKET_UD W0_9_8, ANC_PACKET_UDW0_7_0) through to
(ANC_PACKET_UD W15_9_8, ANC_PACKET_UDW15_7_0).
