Abstract
Abstract A digital video system receives a digital bitstream representing video and audio information and containing a plurality of packetized data programs in a data format and includes data units related to the selection of individual programs and individual packetized datastreams associated with a program. The system includes a first processor responsive to the bitstream for capturing program guide information and a second processor responsive to the bitstream for capturing selected program data. The program guide data includes a base data unit for selecting a first program and a second data unit of predetermined offset to the base data unit for selecting a second program. The second processor captures program data by capturing data with identifiers matching an identifier determined from the data units.
