摘要:
Techniques to efficiently deliver interactive program guide (IPG) to a number of terminals. Each IPG page can be decomposed into a guide portion that is specific to each IPG page and a background portion that is common for all IPG pages. The background portion can be further decomposed into a time-varying video portion and other static portions. One method includes receiving a viewer selection for imagery, where the imagery includes at least one intracoded slice and at least one predictively coded slice, and each of the intracoded and predictively codes slices are associated with respective bitstreams. Packets from the at least one bitstream corresponding to the at least one intracoded slice of the selected imagery are extracted, and packets from the at least one bitstream corresponding to the at least one predictively coded slice of the selected imagery are also extracted. The payload portions of the extracted packets are then arranged to form the selected imagery.
