com.wowza.wms.transport.mpeg2.StreamIdentifierDescriptor

public class StreamIdentifierDescriptor
extends Descriptor

The Class StreamIdentifierDescriptor. The stream identifier descriptor may be used in the PMT to label component streams of a service so that they can be differentiated. The stream identifier descriptor shall be located in the elementary descriptor loop following the relevant ES_info_length field. The stream identifier descriptor shall be used if either the program_splice_flag or the program_segmentation_flag is zero. If stream identifier descriptors are used, a stream identifier descriptor shall be present in each occurrence of the elementary stream loop within the PMT and shall have a unique component tag within the given program.
