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

Description: DIGITAL IMAGERY is pervasive in our world today. Consequently,
standards for the efficient representation and

from the ongoing work of the Joint Photographic Experts

(JTC 1/SC 29/WG 1), a collaborative effort between the International

Description: MPEG-2压缩编码技术原理应用
MPEG是运动图像专家组(Moving Picture Experts Group)的简称，其实质上的名称为国际标准化组织（ISO）和国际电工委员会（IEC）联合技术委员会（JTC）1的第29 分委员会的第11工作组，即ISO/IEC JTC1/SC29/WG11，成立于1988年。其任务是制定世界通用的视音频编码标准。因为，广播电视数字化所产生的海量数据对存储容量、传输带宽、处理能力及频谱资源利用率提出了不切合实际的要求，使数字化难以实现。为此，该专家组基于帧内图像相邻像素间及相邻行间的空间相关性和相邻帧间运动图像的时间相关性，采用压缩编码技术，将那些对人眼视觉图像和人耳听觉声音不太重要的东西及冗余成分抛弃，从而缩减了存储、传输和处理的数据量，提高了频谱资源利用率，制定了如表1所示的一系列MPEG标准,使数字化正在变为现实。其中，MPEG-2是一组用于视音频压缩编码及其数据流格式的国际标准。它定义了编解码技术及数据流的传输协议；制定了MPEG-2解码器之间的共同标准（MPEG-2编码器之间尚无共同标准）。本文以MPEG-2的系统、MPEG-2的编码、及MPEG-2的应用为题，讨论MPEG-2压缩编码技术。

Description: The standardization body ISO/IEC JTC 1/SC 29/WG 11, also known as the Moving Pictures Experts Group
(MPEG), was established in 1988 to specify digital video and audio coding schemes at low data rates. MPEG
completed its first phase of audio specifications (MPEG-1) in November 1992, ISO/IEC 11172-3. In its second
phase of development, the MPEG Audio subgroup defined a multichannel extension to MPEG-1 audio that is
backwards compatible with existing MPEG-1 systems (MPEG-2 BC) and defined an audio coding standard at
lower sampling frequencies than MPEG-1, ISO/IEC 13818-3.-The standardization body ISO/IEC JTC 1/SC 29/WG 11, also known as the Moving Pictures Experts Group (MPEG), was established in 1988 to specify digital video and audio coding schemes at low data rates.

In the simulation experiments, the sharper correlation peaks are showed. The result shows that strong disturbance of zero rank exists in the simulation of JTC, and it is 7.14 times stronger than the useful signal thus, the power spectrum subtraction is used to eliminate the strong disturbance, and the capacity of image recognition is improved.
