    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.

    摘要： Decoder system initialization involves scanning to associate a particular program guide with individual channels. A similar procedure is also performed upon introduction of a new channel. A system for acquiring program guide information conveyed on one of a plurality of broadcast channels involves scanning through received broadcast channels to identify program guides available on individual channels. A program guide of a selected program guide type (e.g. analog-VBI type, MPEG PSI type or ATSC PSIP type) is associated with a broadcast channel by updating a video decoder database. The program guide of the selected program guide type is acquired and used in capturing packetized program information comprising a program conveyed on an individual broadcast channel. In another feature, data received on an individual broadcast channel is examined to identify program guides of particular type in a predetermined order.

    摘要： A television, such as an HDTV receiver, includes a plurality of signal inputs each of which is adapted to receive television signals comprising a plurality of channels and communicate the received television signals to a processor/tuner for selection of the various channels by a user for viewing on a display of the television. A channel search routine for the detection of channels in the television signal is accomplished on the currently designated signal input rather than on all signal inputs of the television. The channels detected during the search of the currently designated signal input are included in a channel list that is stored in memory of the television. A GUI is preferably used to initiate the channel search and is capable of displaying the detected channels relating to the currently selected signal input. Channel lists for each signal input are updated as the channels are detected. A complete channel list may be maintained for all signal inputs as well as individual channel lists for each signal input.
