GS1582 Data Sheet
40117 - 1 November 2007
70 of 114
352M packet will be inserted into the data stream according to the line numbers
programmed in the LINE_352M_f1 and LINE_352M_f2 registers (
Table 4-36
).
Packet insertion will only take place if at least one of the bytes in the
VIDEO_FORMAT_A or VIDEO_FORMAT_B registers are programmed with a
non-zero value (
Table 4-37
). In addition, the 352M_INS bit must be set LOW
(
Table 4-35
).
NOTE: If there are existing 352M packets in the input stream, and ANC_BLANK is
set HIGH (disabled), then the existing data is preserved and new 352M is inserted.
The GS1582 does not overwrite existing 352M data.
The GS1582 will differentiate between PsF and interlaced formats based on bits
14 and 15 of the VIDEO_FORMAT_A register.
The packets will be inserted immediately after the EAV word in SD video streams
and immediately after the line-based CRC word in the luma channel of HD video
streams. If other ancillary packets exist in the horizontal ancillary space 352M
packets will be inserted immediatly following these packets. SMPTE 352M packets
will not be inserted if there is insufficient room in the HANC space.
