channel pair of the group of audio channel pairs carrying the complete audio program.
For example, if there is a six-channel program carried in the first three audio channel
pairs and a stereo program carried by the fourth audio channel pair, then the VANC
packets carrying the metadata for the six-channel program would have their SDID
value set to 02h because the program starts in audio channel pair 1/2. The VANC
packets carrying the metadata for the stereo program would have their SDID value set
to 05h because the stereo program starts in audio channel pair 7/8.
