MPEG-2 multi-program Transport stream (TS) achieves improvement of transmission efficiency by multiplexing several MPEG-2 streams. In this paper, we propose a transcoder that achieves rate reduction of MPEG-2 multi-program TS. For the purpose of realizing MPEG-2 multi-program TS transcoder, this transcoder requires a rate control scheme and remultiplexing scheme: The former improves average SNR values in total of all streams, and the latter achieves the evasion from failure of STD buffer. Next, from simulation experiments, we compare the conventional rate control scheme to the proposed one. On the other hand, we show the state of STD buffer. Finally, we show the effectiveness for our proposed scheme.
