Abstract :
An MPEG-2 to H.264 intra transcoding method is proposed. This method uses the encoding information from an MPEG-2 stream and keeps as many DCT coefficients of the original MPEG-2 bitstream as possible. Experimental results show that the proposed method improves PSNR by about 0.76-1.27 dB compared with a typical conventional method.
