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.

A system for initiating scheduled program processing functions such as program display, recording or playback, derives a time clock based on a current time reference indication produced by a particular broadcast source. The derived time clock is used in initiating scheduled processing functions for programs derived from the particular broadcast source and time clocks derived from sources other than the particular broadcast source are disregarded. The system displays a second time clock different to the derived time clock. In addition, the system forms a composite program guide from data from multiple broadcast sources to associate current time reference indications with their corresponding broadcast sources.

An apparatus performs a data caching operation responsive to a channel change event which reduces channel change times. According to an exemplary embodiment, the apparatus includes a cache memory operative to cache an incoming data stream responsive to a channel change command. A processor is operative to find program specific information included within the incoming data stream. A decoder is operative to decode the cached data stream responsive to the processor finding the program specific information.

An HDTV receiver coupled to a terrestrial antenna displays real-time signal strength of terrestrial digital television signals. A graphical user interface preferably displays various data relating to all terrestrial television signals in a scrollable grid format. The grid is displayed within an active video display of a selected television signal from the grid. Audio for the selected channel is also active. A list of all channels tuned or selected is maintained to aid in searching. Channel lists are updated during certain channel searches.

A method and a system for performing trick mode features in a personal video recorder without introducing a channel change delay during normal viewing. The method includes the steps of recording a video source signal and concurrently bypassing the video source signal to a display device, without experiencing any buffering delay associated with the recording step. During trick mode operation the bypassing step can be automatically terminated and a recorded version of the video source signal can be substituted and sent to the display. The bypassing step further can include substituting, without any buffering delay, an alternate video source signal in response to a user selection of an alternate video source signal channel. A user notification can be generated to acknowledge receipt of a trick mode command. The user notification can be terminated once the step of substituting the recorded version of the video source signal has been completed.

An apparatus and a method for processing programs indicated by the associated program description to be audio-only programs, including the following. A respective program description for programs is received. Upon user selection of a program, a determination is made as to whether the selected program is an audio-only program. If the selected program is an audio-only program, then preprogrammed on-screen display information is displayed while the selected audio-only program is played to provide additional visual entertainment for users.

A system processes packetized program information, from different broadcast sources, containing programs and program specific information including associated content rating data. A program specific parameter of a desired program is selected based on its source from equivalent parameters from alternative broadcast sources. The desired program is processed for display, recording or playback using the selected program specific parameter. The selected program specific parameter may comprise a content rating that is mapped to a different program content rating system and used in multi-level validation of authorization to access the desired program.

In a video processing system and method, individual program channels are allocated first and second identification numbers. The first identification number is associated with an information provider. The second identification number is used in identifying a broadcast sub-channel from among a group of sub-channels associated with the first identification number. The first and second identification numbers in conjunction, are used in identifying data constituting a program transmitted on the broadcast sub-channel. The group of sub-channels are displayed along with the associated information provider in a hierarchical fashion for channel selection purposes.

System and method for displaying major and minor channel numbers

A video decoder provides an interface enabling a User to create, manage and maintain favorite service lists for facilitating User navigation through a complex array of multimedia services. The on-screen display interface system generates an abbreviated menu list of favorite multimedia services available from both local and remote sources to enable navigation through user selected favorite services. A database associates individual services and corresponding menu items in the favorite services menu with their respective sources and supports service selection, tuning and acquisition. Additional abbreviated lists of favorite multimedia services, comprising sub-sets of parent service lists, are also hierarchically displayed in response to User command in order to facilitate and focus a search for a desired service.
