3.9.5 SMPTE 352M Payload Identifier
The GS9090 can receive and detect the presence of the SMPTE 352M payload
identifier ancillary data packet. This four word payload identifier packet may be
used to indicate the transport mechanism, frame rate and line scanning / sampling
structure.
Upon reception of this packet, the device will extract the four words describing the
video format being transported and make this information available to the host
interface via the four VIDEO_FORMAT 8 bit registers (
Table 3-8
). The device will
also indicate the version of the payload packet in bit 7 of the DATA_FORMAT
register (
Table 3-7
). When this bit is set HIGH the received SMPTE 352M packet
is version 1, otherwise it is version 0.
The VIDEO_FORMAT registers will only be updated if the received checksum is
the same as the locally calculated checksum.
NOTE: The VIDEO_FORMAT registers will not be updated with 352M payload
data if the packets are not on the correct video line (as stated in this standard).
These registers will be cleared to zero, indicating an undefined format, if the device
loses lock to the input data stream (LOCKED = LOW), or if the SMPTE_BYPASS
pin is asserted LOW. This is also the default setting after a device reset.
