3.6.2.1 Video Standard Indication
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 3-4
.
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. The VD_STD[4:0] and INT_PROG
bits will also default to zero if the SMPTE_BYPASS pin is asserted LOW or if the
LOCKED output is LOW. The STD_LOCK bit will retain its previous value if the
PCLK is removed.
