Entropy Coding
摘要
As the last stage before the code stream generated by the compression system, entropy coding aims to remove the information redundancy or coding redundancy of the symbols generated in the coding process. Entropy coding is responsible for encoding various transformation coefficients, prediction residuals, motion vectors, and flag information, and it finally generates code streams. This chapter first introduces the basic theory of the main entropy coding technology and then introduces the specific applications of entropy coding in compression systems.
