GS1559 Data Sheet
30572 - 4
July 2005
46 of 74
4.10.3 SMPTE 352M Payload Identifier
The GS1559 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_OUT registers (
Table 4-6
).
The VIDEO_FORMAT_OUT registers will only be updated if the received
checksum is the same as the locally calculated checksum.
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 device reset.
The SMPTE 352M packet should be received once per field for interlaced systems
and once per frame for progressive systems. If the packet is not received for two
complete video frames, the VIDEO_FORMAT_OUT registers will be cleared to
zero.
