This paper studies the HD video and remote sensing image compression algorithm based on fractal and H.264.In order to study the technology of image storage and transmission suitable for HD resolution video. The system further optimizes the intra-frame coding mode currently adopted by H.264, and proposes a new fast intra-block block algorithm to reduce the prediction mode selection. For inter prediction, a new motion estimation and motion compensation algorithm is proposed based on fractal. In order to further reduce the number of coded bits, transform, quantize and entropy encode the fractal residuals. Since the motion vector MV and the fractal coefficients cannot be quantized, their differences are directly entropy encoded. The high-definition video coding system based on fractal and H.264 not only reduces the coding complexity, but also improves the coding efficiency.
