5.9 Arbitrary Data Packets
The GS1503B can demultiplex arbitrary data packets according to SMPTE 291M.
Typically, arbitrary data packets consist 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 demultiplexed from the Luma channel of
the video data stream. A maximum of 255 user data words can be demultiplexed.
