bsid (AC-3) [ATSC Semantics]
The bsid is a 5-bit unsigned integer field in an ATSC AC-3 descriptor that gives the bsid of an AC-3 service and must match the bsid value in the packetized AC-3 elementary stream Initially, the only permitted value for this field was 8 / 0x0F. Revisions of the ATSC A/52 specification now permit additional values for this field.
