  • Patent number: 6675385
    Abstract: An MPEG-2 digital TV headend and settop box includes a method and apparatus for enabling the presentation of electronic program guide (EPG) information. Television program guide information is downloaded from a source of television programming data to the headend of the TV broadcast system. The downloaded EPG data is translated into a plurality of HTML Web pages, which are continuously transmitted as a rotating data carousel in an MPEG-2 data stream. The digital TV settop box further includes a general-purpose web browser responsive to viewer commands to select and display a selected web page from the rotating carousel of HTML web pages. The digital TV settop further includes a data cache for downloading and storing partial HTML web page EPG information in advance, which reduces the necessary bandwidth allocated for the EPG information, and allows the settop box to quickly display the basic information for a channel related program guide.
