GS9092A Data Sheet

February 2006

3.7.3.1 SMPTE 352M Payload Identifier Generation and Insertion
If the 352M_INS bit of the IOPROC_DISABLE register is set LOW, the GS9092A
can generate and insert SMPTE 352M payload identifier ancillary data packets into
the data stream automatically or based on information programmed into the host
interface.
When the 352M_CALC bit of the IOPROC_DISABLE register is set HIGH, the user
must program the SMPTE 352M packet to be inserted into the VIDEO_FORMAT
registers (
Table 3-5
). In addition, the line number(s) in which the packet is to be
inserted must be programmed in the 352M_LINE_1 and 352M_LINE_2 registers
(
Table 3-6
). If both line number registers are set to zero, no packets will be
inserted.
NOTE: The user must program the SMPTE 352M packet into the
VIDEO_FORMAT registers prior to programming the line number(s) in which the
packet is to be inserted.
NOTE: It is the responsibility of the user to ensure that there is sufficient space in
the horizontal blanking interval for the insertion of the SMPTE 352M packets.
These packets will be inserted immediately after the EAV word on the line
designated in the standard or by the user
If there are other ancillary data packets present, the SMPTE 352M packet will be
inserted in the first available space in the HANC. Ancillary data must be contiguous
from the EAV. When there is insufficient space available, the 352M packets will not
be inserted.
When the 352M_CALC bit of the IOPROC_DISABLE register is set LOW, the
GS9092A will automatically generate and insert 352M packets into the video
stream. The device will also write the generated packet into the VIDEO_FORMAT
registers.
NOTE: When the IOPROC_EN pin is set HIGH and all registers contain their
default values, the VIDEO_FORMAT registers are set to 0h and do not contain the
SMPTE 352M packet.
The SMPTE 352M packet will be inserted into the data stream according to the line
number and sample position defined in the standard.
The 4:3/16:9 bit of the SMPTE 352M packet will be set LOW by default to denote
4:3. For video payloads where 16:9 images are transmitted over 270Mb/s links, the
user must program the SMPTE 352M packet accordingly.
The video payload identifier packet will be version 1 and comply with the structure
defined in SMPTE 352M-2002.
NOTE: The user should turn off SMPTE 352M packet insertion when serializing
SDTI signals.
