GS1559 Data Sheet
30572 - 4
July 2005
58 of 74
4.10.6.1 Illegal Code Remapping
If the ILLEGAL_REMAP bit of the IOPROC_DISABLE register is set LOW, the
GS1559 will remap all codes within the active picture between the values of 3FCh
and 3FFh to 3FBh. All codes within the active picture area between the values of
000h and 003h will be re-mapped to 004h.
In addition, 8-bit TRS and ancillary data preambles will be remapped to 10-bit
values if this feature is enabled.
4.10.6.2 EDH CRC Error Correction
The GS1559 will generate and insert active picture and full field CRC words into
the EDH data packets received by the device. This feature is only available in SD
mode and is enabled by setting the EDH_CRC_INS bit of the IOPROC_DISABLE
register LOW.
EDH CRC calculation ranges are described in
EDH CRC Error Detection on
page 53
.
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.
4.10.6.3 Ancillary Data Checksum Error Correction
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 (
Programmable Ancillary Data Detection on page 45
), only the
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.
4.10.6.4 Line Based CRC Correction
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.
4.10.6.5 HD Line Number Error Correction
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
Automatic Video Standard and Data Format
Detection on page 47
).
This feature is enabled when SD/HD = LOW, and the LNUM_INS bit of the
IOPROC_DISABLE register is set LOW.
