| Abstract: |
An efficient MPEG2 to H.264 half-pixel motion compensation transcoding method is proposed. The Inter macroblock transcoding is implemented in the transform domain. An algorithm is designed to compensate for the errors which arise because of the different half-pixel interpolation procedures used by MPEG2 and H.264/AVC. The experimental results show that the PSNR values of the transcoded H.264 streams result in significant improvement (average 5.5 dB) after we reduce the half-pixel interpolation errors. |
