For the purposes of the example, we will also assume that the data identification (DID) and secondary
data identification (SDID) of the four metadata channels are 0x45 and 0x01, 0x02, 0x03 and 0x04.
Remember that there are twelve SMTPE 2020 embedder channels (four each for the PGM, PST and
CLN buses) but the DID an SDID settings for the channels are common across all three buses. For
example, if PGM metadata channel one (VANC 1) is 0x45 and 0x01 for the DID and SDID respectively
then VANC 1 for PST and CLN will also be also use 0x45 and 0x01.
The following metadata routing settings are required:
Table 9-5: Metadata Routing Example 2
This configures all four metadata channels to use metadata from the DE decoders. VANC insertion has
already been enabled by setting the insertion lines for channels 1/2 and 3/4. Because the VANC insertion
has been enabled the SMPTE 2020 embedder will use the meta 1, 2, 3 and 4 sources as configured in
the table above.
