Then the use of traditional compression methods into the MPEG-2 standard in detail,for example DCT transform, motion estimation and compensation, uniformquantization, run length coding and variable length coding, etc are discussed.

• 接下来详细的讨论了各种传统的压缩方法是如何具体应用到标准MPEG-2中的，例如DCT变换、估计预测编码、均匀量化、行程编码和可变长编码。
