Advanced Marco-Block Entropy Coding for Advanced Video Standards先進影像標準的巨塊熵編碼

总结

The major part of multimedia applications (such as video conferencing and digital TV broadcasting) is video processing due to its high encoding complexity. The objective of current advanced video standards (including H.264 and AVS) is to achieve higher coding efficiency. In order to meet the objective, advanced entropy coding is required.

In this invention, the proposed entropy coding for advanced video standards is described based on new features of advanced video standards. In low bit-rate video coding, larger quantization parameters are used to give a smaller number of bits spent on residue data. As a result, the header overhead is a dominant factor of yielding the overall bit rates, especially in advanced video standards. Based on new features of MB header properties, we propose an advanced coding algorithm for entropy coding of MB header. The experimental results suggest that, compared with existing entropy coding algorithm, our scheme can achieve higher coding efficiency.
