EDH error flags (EDH, EDA, IDH, IDA, and UES) for ancillary data, full field, and
active picture will also be inserted. These flags must be programmed into the
EDH_FLAG registers of the device by the application layer (
Table 3-8
).
NOTE 1: It is the responsibility of the user to ensure that the EDH flag registers are
updated once per field.
The prepared EDH packet will be inserted at the appropriate line of the video
stream according to RP 165. The start pixel position of the inserted packet will be
based on the SAV position of that line such that the last byte of the EDH packet
(the checksum) will be placed in the sample immediately preceding the start of the
SAV TRS word.
NOTE 2: It is also the responsibility of the user to ensure that there is sufficient
space in the horizontal blanking interval for the EDH packet to be inserted.
CRC Update of Existing Packets
When the EDH_CRC_UPDATE bit is set HIGH, the GS9092A will not generate any
new EDH packets, but will instead update the CRC bytes of the existing EDH
packets within the input video data stream. Incoming EDH flags are preserved and
can be read from the EDH_FLAG register, which becomes read-only (
Table 3-8
).
When EDH packets are detected, the EDH_FLAG register is updated on each field.
These registers will be cleared LOW if no EDH packet is detected during blanking
at the end of the vertical blanking period (falling edge of V).
The validity or ‘V’ bits of the incoming EDH packet will also be set to ‘1’ to denote
that the CRC calculations are valid. The EDH packet checksum word is also
re-calculated and re-inserted.
When incoming EDH packets are updated, the location of the packets within the
video stream remains unchanged. EDH packets that are to be updated can be
present anywhere within the horizontal blanking region of the vertical blanking
period.
