ABSTRACT:
The present invention provides a virtual channel table (VCT) data structure, transport stream discrimination method, and digital broadcast receiver, by which streams transferred within a channel can be identified with VCT only by extending a VCT syntax according to PSIP (program and system information protocol) of ATSC (advanced television systems committee) prescribed as a digital TV standard. The present invention adds the additional explanation (component name string) descriptor for the stream to the service location descriptor of the VCT, whereby various streams transferred over one channel can be uniquely identified. Therefore, the present invention enables a user of the digital broadcast receiver to select a stream more quickly.
