  • receiving a digital broadcast signal including a transport stream comprising a plurality of elementary streams and a plurality of multimedia descriptors, each multimedia descriptor identifying characteristics associated with at least one of the plurality of multimedia streams, the characteristics including elementary stream identification and category, and each multimedia descriptor preceding the multimedia stream with which it is associated wherein each descriptor describes the elementary stream with which it is associated and comprises one or more key words embedded within the digital broadcast signal;

    identifying one or more elementary streams associated with one or more multimedia descriptors that match a set of preprogrammed interest category parameters;

    caching the entirety of the one or more identified elementary streams responsive to the one or more identified elementary streams matching the set of preprogrammed interest category parameters; and

    automatically generating a customized information page operable to simultaneously include the preprogrammed interest category parameters and a list comprising a plurality of cached elementary streams sorted based upon the preprogrammed interest category parameters into which the plurality of cached elementary streams belong, the cached elementary streams being available for retrieval by a user and a selected cached elementary stream being operable to be displayed simultaneously with the list of cached elementary streams sorted by preprogrammed interest category parameter.
