Stream conversion to support interactive video playout

Abstract

Interactive playout of MPEG-encoded video entails new ways of handling data. Transforming the standard MPEG stream to a local form at the player device enables efficient interactive playout even when available buffer space is constrained. A stream conversion scheme that encodes P frames as I frames after decompression and playout of each P frame eliminates extra memory needs, making P-I conversion a cost-effective solution.
