4.10.4 Automatic Video Standard and Data Format Detection
The GS1559 can independently detect the input video standard and data format by
using the timing parameters extracted from the received TRS ID words. This
information is presented to the host interface via the VIDEO_STANDARD register
(
Table 4-7
).
Total samples per line, active samples per line, total lines per field/frame and active
lines per field/frame are also calculated and presented to the host interface via the
RASTER_STRUCTURE registers (
Table 4-8
). These line and sample count
registers are updated once per frame at the end of line 12. This is in addition to the
information contained in the VIDEO_STANDARD register.
After device reset, the four RASTER_STRUCTURE registers default to zero.
4.10.4.1 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 4-9
.
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 device loses lock to the input data stream,
(LOCKED = LOW), or if the SMPTE_BYPASS pin is asserted LOW. The
STD_LOCK bit will retain its previous value if the input is removed.
