Abstract :
This paper proposes a fast MPEG-2 to H.264 intra frame transcoding method. It deploys a novel technology in the refering process of MPEG-2 discrete cosine transform (DCT) coefficients to determine the block size and the prediction mode of intra frame prediction for H.264. The proposed method reduces the coding complexity by approximately 60% while maintaining a peak signal to noise ratio (PSNR) compared with a typical baseband conversion.
