| Popis: | 95 Internet Protocol Television (IPTV) is now the hottest interaction internet TV system in the world. In order to reduce the cost of IPTV set, we design a efficient H.264 lossless compression method to reduce its hardware. Traditional H.264 base on intra prediction and efficient entropy coding is not able to provide a better compression ratio than JPEG-LS and JPEG 2000. In this thesis, we suggest adaptive entropy coding (AEC)and adaptive binary arithmetic coding(ABAC) to improve the compression ratio of H.264-LS, where the image variation content (ICV) can be easily obtained from the intra prediction residues. For adjusting adaptive the entropy coding, we can use the New H.264-LS compression algorithm and adaptive binary arithmetic coding (ABAC) to obtain efficient H.264-LS. The simulation results show that the proposed H.264-LS can achieve more 24.8% compression ratio than original H.264-LS and have better video compression technique than traditional lossless compression method. |
