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”. This document describes the transform and quantization processes defined, or implied, by the standard.

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 [1,2] will be known as H.264 and also MPEG-4 Part 10, “Advanced Video Coding”. This document describes the methods of predicting intra-coded macroblocks in an H.264 CODEC.

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 Coding is assumed.

ITU-T 第16 研究組（2005-2008 年）按照 ITU-T A.8 建議書規(guī)定的程序，于2005 年3 月1 日批準(zhǔn)了 ITU-T H.264（2005年）建議書

為什么叫H.264 H.264是一種視頻高壓縮技術(shù)，全稱是MPEG-4 AVC，用中文說是“活動圖像專家組-4的高等視頻編碼”，或稱為MPEG-4 Part10。它是由國際電信標(biāo)準(zhǔn)化部門ITU-T和規(guī)定MPEG的國際標(biāo)準(zhǔn)化組織ISO/國際電工協(xié)會IEC共同制訂的一種活動圖像編碼方式的國際標(biāo)準(zhǔn)格式，這是我們叫慣了的MPEG中的一種，那為什么叫H.264呢？

PlotSphereIntensity(azimuth, elevation) PlotSphereIntensity(azimuth, elevation, intensity) h = PlotSphereIntensity(...) Plots the intensity (as color) of a number of points on a unit sphere. Input: azimuth (phi), in degrees elevation (theta), in degrees intensity (optional, if not provided, a green sphere is produced) All inputs must be vectors or matrices of the same size. Data does not have to be evenly spaced. When there aren t enough points to draw a smooth sphere, additional points (with color) are interpolated. Output: h - a handle to the patch object The axes are also plotted: positive x axis is red positive y axis is green positive z axis is blue
