  Abstract

In this paper, we present a transcoding algorithm for converting an MPEG-2 video bitstream to an H.264 bitstream. The proposed transcoder consists of two parts. One is MPEG2 decoding part and the other is H.264 encoding part. Because our algorithm is for transcoding in the spatial domain, MPEG2 decoding part carries out full decoding of MPEG2 bitstream. While, because macroblock type and coded block pattern in MPEG2 are significantly related to macroblock mode in H.264, macroblock mode is selected adaptively according to macroblock type and coded block pattern in H.264 decoding part. Furthermore, motion vector is also used as side-information for 16x16 macroblock mode. Simulation results show that the proposed transcoder yields high reduction of total transcoding time at comparable PSNR.
