Data structure and methods for providing an interactive program guide |
摘要 |
A data structure suited to efficiently representing a plurality of image streams including common and non-common portions. Specifically, a plurality of similar group of picture (GOP) data structures representing the corresponding plurality of image streams including common and non-common portions is adapted to provide a first encoded stream comprising only P-picture and B-picture access units of one of the similar GOP data structures, and a corresponding plurality of encoded streams comprising only respective I-picture access units of the similar GOP data structures. In this manner, the redundant P-picture and B-picture access units within the encoded streams are eliminated, thereby greatly reducing the bandwidth or memory resources needed to transmit or store the plurality of image streams.
