3.6.3.4 Ancillary Data Checksum Generation and Insertion
The GS9062 will calculate checksums for all detected ancillary data packets
presented to the device. These calculated checksum values are inserted into the
data stream prior to serialization.
Ancillary data checksum generation and insertion will only take place if the
ANC_CSUM_INS bit of the IOPROC_DISABLE register is set LOW.
3.6.3.5 TRS Generation and Insertion
The GS9062 can generate and insert 10-bit TRS code words into the data stream
as required. This feature is enabled by setting the TRS_INS bit of the
IOPROC_DISABLE register LOW.
TRS word generation will be performed in accordance with the timing parameters
generated by the flywheel which will be locked either to the received TRS ID words
or the supplied H, V, and F timing signals

.
3.7 Parallel-To-Serial Conversion
The parallel data output of the internal data processing blocks is fed to the
parallel-to-serial converter. The function of this block is to generate a serial data
stream from the 10-bit or 20-bit parallel data words and pass the stream to the
integrated cable driver.
