4.10.6.3 Ancillary Data Checksum Error Correction
4.10.6.4 Line Based CRC Correction
4.10.6.5 HD Line Number Error Correction
4.10.6.6 TRS Error Correction
4.10.7 EDH Flag Detection
NOTE: Although the GS1559 will modify and insert EDH CRC words and EDH
packet checksums, EDH error flags will not be updated by the device.
When ancillary data checksum error correction and insertion is enabled, the
GS1559 will generate and insert ancillary data checksums for all ancillary data
words by default. Where user specified ancillary data has been programmed into
the device
checksums for the programmed ancillary data types will be corrected.
This feature is enabled when the ANC_CSUM_INS bit of the IOPROC_DISABLE
register is set LOW.
The GS1559 will generate and insert line based CRC words into both the Y and C
channels of the data stream. This feature is only available in HD mode and is
enabled by setting the CRC_INS bit of the IOPROC_DISABLE register LOW.
In HD mode, the GS1559 will calculate and insert line numbers into the Y and C
channels of the output data stream.
Line number generation is in accordance with the relevant HD video standard as
determined by the device, (see
Detection on page
This feature is enabled when SD/HD = LOW, and the LNUM_INS bit of the
IOPROC_DISABLE register is set LOW.
When TRS error correction and insertion is enabled, the GS1559 will generate and
insert 10-bit TRS code words as required.
TRS word generation will be performed in accordance with the timing parameters
generated by the flywheel to provide an element of noise immunity. As a result,
TRS correction will only take place if the flywheel is enabled, (FW_EN/DIS =
HIGH).
In addition, the TRS_INS bit of the IOPROC_DISABLE register must be set LOW.
As described in
EDH packets in the received data stream. The EDH flags for ancillary data, active
picture and full field areas are extracted from the detected EDH packets and placed
in the EDH_FLAG register of the device
