NOTES:
1. The Line Numbers in brackets refer to version zero SMPTE 352M packet locations, if they are different from version 1.
2. The part may provide full or limited functionality with standards that are not included in this table. Please consult a Gennum technical
representative.
By default (at power up or after system reset), the four RASTER_STRUC_X, STD_LOCK
and INT/PROG registers are set to zero. These registers are also cleared when the
SMPTE_BYPASS pin is LOW, or the LOCKED pin is LOW.
NOTE 1: The Line Numbers in brackets refer to Version zero SMPTE 352M packet
locations, if they are different from the Version one locations.
NOTE 2: 3G formats cannot be fully determined from these measurements. Their
detailed information will be derived from SMPTE 352M packets, which must be in the
video stream as a mandatory requirement of the SMPTE 424M specification, as
described below.
4.8.2 3G Format Detection
Format detection is more difficult for 3G signals, as there are two levels of signal (Level
A and Level B) and multiple mappings within each level. Timing information is not
sufficient to fully decode the video format.
For this reason SMPTE 352M video payload identifier packets are mandatory for all
SMPTE 424M serial signals.
