Abstract

We propose a VC-1 to H.264/AVC intra transcoding method. This method uses the encoding information from a VC-1 stream and keeps as many DCT coefficients of the original VC-1 bitstream as possible. Experimental results show that the proposed method improves PSNR by about 0.44-1.34 dB compared with a conventional method.
