2.9 ARBITRARY DATA PACKETS
The GS1503 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 GS1503 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. Figure 41 shows the structure of the
arbitrary data packet.
Fig. 41 Arbitrary Data Packet Structure
2.9.1 Arbitrary Data Demultiplexing in External Pin Mode
This is the default mode for demultiplexing arbitrary data
packets. The GS1503 will set the PKTEN external pin HIGH
before arbitrary data will be output. Two VCLK cycles after
PKTEN goes HIGH, arbitrary data is output on the PKT[7:0]
bus. See Figure 42 for timing.
The following arbitrary data is output on the PKT[7:0] bus:
Data ID (DID), Secondary Data ID (SDID), Data Count (DC)
and User Data Words (UDW: up to a maximum of 255
words).
