Abstract
MPEG-2 transcoding scheme is proposed as scalable transmission system for a video-on-demand system is described. In this system video contents encoded by MPEG-2 are transmitted to receiver terminals via communication lines that have different bit rate. A transcoding technique that directly converts a bit stream encoded by MPEG-2 into a lower coding rate stream without decoding is proposed. The transcoder called Trampeg includes size reduction and frame drop approach. The experimental results show that an MPEG-2 stream of 0 Mbps is able to be transcoded into a stream of 1.5 Mbps-300 Kbps.
