This paper addresses the problem of supporting interactive playout of an MPEG encoded video stream at a player device. The authors devised a stream conversion scheme that encodes P frames as I frames after the decompression and playout of each P frame. P-I conversion is shown to be cost-effective, easy to implement, and able to provide high visual quality interactive playout, and is therefore deemed a viable approach to supporting interactive playout for MPEG video in a client station.
