A method and apparatus (fig. 1) for compressing a plurality of video sequences (fig. 2, V1-V10) where each sequence (V1-V10) has information that is common with other sequences. The invention ensemble encodes (fig. 2, 220) the video sequences (fig. 2, V1-V10) into an MPEG compliant transport stream (fig. 1, E1-E10) using less predicted frame information than separately encoding each video sequence (fig. 2, V1-V10). One illustrative application of the invention is efficiently encoding (fig. 2, items 220) and transmitting (fig. 1, 104) a user interface such as a program guide (fig. 5, 560), navigator (fig. 5, 570) and the like. The user interface (fig. 5, 560) is illustratively embodied in an interactive programming guide (IPG). |
