Consumer interface for a digital television system

摘要

A digital video system receives a digital bitstream representing video information and containing a plurality of packetized data programs (PR1, PR2, PR3, ...) in a data format that includes packet identifiers (SCID) for identifying individual programs and individual packetized datastreams (Vi, Ai, Di) associated with a program. The system includes a first processor (612) responsive to the bitstream for capturing program guide information (D4) and for capturing selected program data. The program guide data includes a predetermined base packet identifier (SCID1) for identifying a first program (PR1) and a second packet identifier (SCID2) having a value of predetermined offset to the base packet identifier value for identifying a second program (PR2). The processor captures program data by capturing data with packet identifiers matching a packet identifier selected from identifiers including the base packet identifier and the second packet identifier.
