43 / 63 page  GS9092A GenLINX® III 270Mb/s Serializer for SDI and DVB-ASI Data Sheet 34715 - 4 May 2010 43 of 63 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. |
