  • System, method, computer program product, and apparatus for automatically ensuring consistency between program and system information protocol tables and program specific information tables in a digital television stream
    Patent number: 7971220
    Abstract: A system, method, computer program product, and apparatus for automatically ensuring consistency between program and system information protocol (PSIP) tables and program specific information (PSI) tables in a digital television (DTV) stream, for example, in ATSC DTV stream. Encoders generate MPEG streams including PSI tables. A PSIP generator generates PSIP information from program information. A remultiplexer combines the MPEG information and the PSIP information while resolving any conflicts between the PSI tables and the PSIP tables based on a set of rules. The transport stream output by the remultiplexer includes consistent information in both the PSI tables and the PSIP tables.

    Abstract: A system, method, computer program product, and apparatus for automatically ensuring consistency between program and system information protocol (PSIP) tables and program specific information (PSI) tables in a digital television (DTV) stream, for example, in ATSC DTV stream. Encoders generate MPEG streams including PSI tables. A PSIP generator generates PSIP information from program information. A remultiplexer combines the MPEG information and the PSIP information while resolving any conflicts between the PSI tables and the PSP tables based on a set of rules. The transport stream output by the remultiplexer includes consistent information in both the PSI tables and the PSIP tables.
