Description: G721-G723 源代码
G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate. The four bit rates associated with G.726 are often referred to by the bit size of a sample, which are 2-bits, 3-bits, 4-bits, and 5-bits respectively.

Description: 建议说明了一个可以用来压缩包含低比特率情况下的有运动图象成分的视听服务的编码表示。视频信号编码的基本构造是基于ITU-T的H.261建议，它是通过帧间预测编码去除时间上的冗余和通过对保留信号进行变换编码来去除空间上的冗余的结合。源编码器可以在五种标准图象格式上工作：sub-QCIF, QCIF, CIF, 4CIF和 16CIF。

Description: Scalable video coding Summary: This document contains a detailed description of the usage and configuration of the JSVM (Joint Scalable Video Model) software for the Scalable Video Coding (SVC) project of the Joint Video Team (JVT) of the ISO/IEC Moving Pictures Experts Group (MPEG) and the ITU-T Video Coding Experts Group (VCEG). It provides information how to build the software on Windows 32/64 bit and Linux 32/64 bit platforms. It contains a description of the usage and configuration for the binaries built from the software package, including examples for spatial, SNR and combined scalability scenarios. Guidelines for the integration and validation of new tools in the software are provided.

Description: The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for
the coding (compression) of natural video images. The new standard [1] will be known as H.264 and
also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding:
Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC).
This document provides a short introduction to CABAC. Familiarity with the concept of Arithmetic
