中文摘要：
AVS是我国具备自主知识产权的第二代信源编码标准。为了避免使用其他国际信源编码标准的专利技术，需要新的变换和量化方法。通过对H．264／JVC国际标准中的变换和量化方法的研究，提出一种适用于AVS的整数DCT变换和量化方法。它采用较低复杂度的4×4整数变换矩阵，计算简单，只需加法和移位操作，编码效率较高。
英文摘要：
AVS is the second-generation encoding standard of China with independent intellectual property. In order to avoid using the patent of other international code standards, a new method of transformation ＆ quantization is needed. Based on the research of transform ＆ quantization of H. 264, this paper proposes a new method of DCT for AVS. This method, free from multiplication, has significantly lower computational complexity than that in the current standard. The transform can be computed in 16-bit arithmetic with 4×4 matrix and the coding efficiency is better than other methods.
