service component

“channel” within the multiplex of a TPEG stream with each stream comprising a number of these “channels” which are identified by the component identifier in ISO/TS 18234-2 (TPEG-SSF) and linked to the COID and AID in the TPEG-SNI application
NOTE 1 to entry: Each service component carries an application instance service identification.
