Table 8: Host Interface Description for Raster Structure Registers
3.10.4.1 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 9 below.
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 HIGH if the detected video standard is progressive and
LOW 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 or power up. 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.
