Hybrid Video Coding
Image and video compression is a concrete application of Shannon’s source coding.
For example, the entropy coding used in image and video compression is variants
of Huffman coding and arithmetic coding that were discussed in Sections 1.2.1 and
1.2.2, respectively. The quantization is also developed from Shannon’s rate distor-
tion theory that was discussed in Section 1.2.3. However, the redundancy of image
and video is more complicated than the sources studied in information theory. It is
hard to characterize it by simple statistical models. Therefore, more compression
technologies have to be developed to handle the complicated redundancy.
2.1 Hybrid Coding Framework
Let us take video as an example to discuss redundancy ...
