SYSTEM FOR PROGRAM SPECIFIC INFORMATION ERROR MANAGEMENT IN A VIDEO DECODER
摘要
A processing system decodes packetized program information including ancillary program specific information comprising a plurality of hierarchically ordered information tables. The ancillary information is used in acquiring and decoding packetized program information to provide a video program for display. The processing system employs a method involving detection of a mismatch between a version number of a first table of the program specific information (e.g. a virtual channel table (VCT), or channel information table (CIT)) and a corresponding version number of the first table conveyed in a second table (e.g. a master guide table (MGT)). If a mismatch is detected, the first and second tables are forced to contain a compatible first table version number. The packetized program information is decoded to provide a video program for display using the program specific information including the first and second tables including the forced compatible version number. A detected mismatch may also be disregarded to enable the decoding of the packetized program information and a User's channel line-up may be edited to remove channels associated with a detected mismatch or other program specific information error condition.
