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.
NOTE: Arbitrary data packets will not be multiplexed in the two lines following the
video switching point (see
Figure 4-21: Arbitrary Data Packet Structure
Proprietary and Confidential
Figure 4-21
shows the structure of the arbitrary data packet.
