Abstract:
1. A method, comprising: transmitting a digital broadcast transmission applying a hierarchical modulation, transmitting a signaling table comprising a descriptor of the digital broadcast transmission, wherein said descriptor is configured to indicate how a hierarchical priority is configured to be mapped to a transport stream carried in said digital broadcast transmission, providing information on how said hierarchical priority is configured to be mapped to said transport stream carried in said digital broadcast transmission, providing information identifying said transport stream for parsing at a receiver, providing information identifying said hierarchical priority for parsing at said receiver, and linking the information identifying said transport stream and the information identifying said hierarchical priority so as to map said transport stream into said priority, wherein said signaling table is configured to identify said transport stream, and said descriptor is configured to identify said hierarchical priority of said transport stream so that said hierarchical priority of said transport stream can be identified at said receiver so as to select the transport stream in accordance with said hierarchical priority.
