Research And Hardware Implementation Of Integer Cosine Transform And Quantization In H.264

H.264 is the new generation of video coding standard. The new standard has characters such as low bit rate, high quality picture, strong error fix ability and network adaptive ability. It will be used in video conference, video on demand, digital TV and handheld device. The good performance of H.264 is at the cost of the complexity in the coding and decoding. Compared to the other standard such as MPEG-4, H.264 needs more hardware performance. Because H.264 is the new video coding standard, the selection and implementation of the algorithm has not been well optimized. There are a lot of job has to be done to improve the performance of the H.264 coder and decoder. The research of the critical algorithm and its implementation in H.264 coder and decoder is very helpful for the application of this new standard.In H.264, the integer cosine transform is used. This can help to reduce the complexity in coding and decoding. Furthermore, in H.264 the transform and quantization is combined together. The first part of this research...
