Defines an elementary stream, i.e. an MPEG-2 PID. Used to build the service location descriptor and the PMT. Elementary stream name, carried in the component name descriptor (A/65B 6.9.8) Defines the CA systems in use for the elementary stream and the corresponding ECM PIDs Identify the elementary stream that carries the DSI messages of an object carousel (A/101 10.6.2.2) Identify the Program Element that contains the AIT (A/101 10.6.2.3) Identify the elementary stream that carries the principal component of an object carousel (A/101 10.6.2.4) Defines the association between a component_tag and a PID (ETSI EN 300 468 V1.5.1 6.2.36) Defines the Association between an association_tag and a PID (ISO/IEC 13818-6 11.5.2) These descriptors go into the inner loop of the PMT These descriptors go into the inner loop of the PMT PID used to carry the elementary stream stream_type as defined by MPEG-2 and ATSC and carried in the PMT and service location descriptor ID of an audio stream in a channel. Links to an Ac3Audio element. Carousel Identifier Descriptor (A/101 10.6.2.2) Identification of the data carousel identify whether the carousel supports the enhanced boot mechanism or not Identifier of the module in the carousel the size in bytes of every block in the module the size of the module in bytes compression algorithm defined in IETF RFC 1950 the size of the data (in bytes) carried by the module before it was compressed timeout in seconds for acquisition of all blocks of the module Identify the BIOP messae that is the ServiceGateway message Application Signalling Descriptor (A/101 10.6.2.3) the application type of an Application Information Table sub-table that is on this elementary stream Data Broadcast Id Descriptor (A/101 10.6.2.4) Describes the Information about application types contained in the descriptor Stream Identifier Descriptor (ETSI EN 300 468 V1.5.1 6.2.36) Identifies the component stream for associating it Association Tag Descriptor (ISO/IEC 13818-6 11.5.2) Identifies the connection on which the DII message is broadcast List of the association tag Identifies the connection on which the DII message is broadcast List of the application type Indicate the type of the application indentify whether the carousel supports the enhanced boot mechanism or not
