3.9.7.1 Video Standard Error Detection
If a mismatch between the received SMPTE 352M packets and the calculated
video standard occurs, the GS9090A will indicate a video standard error by setting
the VD_STD_ERR bit of the ERROR_STATUS register HIGH. The device will
detect errors in both version 1 and version 0 352M packets.
3.9.7.2 EDH CRC Error Detection
The GS9090A calculates the Full Field (FF) and Active Picture (AP) CRC words
according to SMPTE RP165 in support of Error Detection and Handling packets in
SD signals.
These calculated CRC values are compared with the received CRC values. If a
mismatch is detected, the error is flagged in the AP_CRC_ERR and/or
FF_CRC_ERR bits of the ERROR_STATUS register. These two flags are shared
between fields 1 and 2.
The AP_CRC_ERR bit will be set HIGH when an active picture CRC mismatch has
been detected in field 1 or 2. The FF_CRC_ERR bit will be set HIGH when a full
field CRC mismatch has been detected in field 1 or 2.
EDH CRC errors will only be indicated when the device has correctly received EDH
packets.
SMPTE RP165 specifies the calculation ranges and scope of EDH data for
standard 525 and 625 component digital interfaces. The GS9090A will utilize these
standard ranges by default.
