The video standard codes reported in the VD_STD[4:0] bits of the
VIDEO_STANDARD register represent the SMPTE standards as shown in
Table
In addition to the 5-bit video standard code word, the VIDEO_STANDARD register
also contains two status bits. The STD_LOCK bit will be set HIGH whenever the
flywheel has achieved full synchronization. The INT_PROG bit will be set LOW if
the detected video standard is progressive and HIGH if the detected video
standard is interlaced.
The VD_STD[4:0], STD_LOCK and INT_PROG bits of the VIDEO_STANDARD
register will default to zero after device reset. These bits will also default to zero if
the device loses lock to the input data stream, (LOCKED = LOW), or if the
SMPTE_BYPASS pin is asserted LOW.
