Abstract
A method and apparatus for compressing a plurality of video sequences, where each sequence has information that is common with other video sequences. The invention ensemble encodes the video sequences into an MPEG compliant transport stream using less predicted frame information than separately encoding each video sequence. One illustrative application of the invention is efficiently encoding and transmitting a user interface such as a program guide, interactive program guide, electronic program guide, navigator and the like. The user interface is illustratively embodied in an interactive program guide (IPG).
