4.11 Arbitrary Data Packets
The GS1503B can multiplex arbitrary data packets according to SMPTE 291M. Typically,
this consists of linear time code (LTC), vertical interval time code (VITC) or other user
data, which is multiplexed once per video field. The GS1503B has two modes in which
arbitrary data can be multiplexed into the Luma channel of the video data stream. A
maximum of 255 user data words can be multiplexed in one packet. Figure 4-21 shows
the structure of the arbitrary data packet.
NOTE: Arbitrary data packets will not be multiplexed in the two lines following the
video switching point (see Video Switching Line Setting on page 35).
