Summary This Recommendation | International Standard represents an evolution of the existing video coding standards (H.261, H.262, and H.263) and it was developed in response to the growing need for higher compression of moving pictures for various applications such as videoconferencing, digital storage media, television broadcasting, Internet streaming, and communication. It is also designed to enable the use of the coded video representation in a flexible manner for a wide variety of network environments. The use of this Recommendation | International Standard allows motion video to be manipulated as a form of computer data and to be stored on various storage media, transmitted and received over existing and future networks and distributed on existing and future broadcasting channels. The revision approved 2005-03 contains modifications of the video coding standard to add four new profiles, referred to as the High, High 10, High 4:2:2, and High 4:4:4 profiles, to improve video quality capability and to extend the range of applications addressed by the standard (for example, by including support for a greater range of picture sample precision and higher-resolution chroma formats). Additionally, a definition of new types of supplemental data has been specified to further broaden the applicability of the video coding standard. Finally, a number of corrections to errors in the published text have been included. This revision, in addition to enhancing video coding capability, will serve to maintain technical alignment with the corresponding jointly-developed ISO/IEC 14496-10 standard. Corrigendum 1 to ITU-T Rec. H.264 corrected and updated various minor aspects to bring the ITU-T version of the text up to date relative to the April 2005 output status approved as a new edition of the corresponding jointly-developed and technically-aligned text ISO/IEC 14496-10. It additionally fixes a number of minor errors and needs for clarification and defines three previously-reserved sample aspect ratio indicators. This edition includes the text approved 2005-03 and its Corrigendum 1 approved 2005-09.

摘 要 本建议书|国际标准是由已有视频编码标准发展而来(H.261，H.262和H.263)，以适应各种应用，如视频会议，数字存储媒体，电视广播，互联网流式传输和通信等，对运动图像压缩比提出的更高要求，本编码标准正是为了满足这种日益增长的需求而开发的。同时，本标准的设计也能够使编码图像能够以灵活的方式在不同的网络环境中使用。使用本建议书|国际标准可使得运动图像能以计算机数据的形式被使用，并能够存储在各种存储媒体上，在现有或未来网络中传送和接收，在现有或未来广播信道中分发。 本版本于2005年3月通过，包含的修改是对视频编码标准增加了四个简表，分别是高级，高级 10，高级 4:2:2和高级 4:4:4，提高了视频质量能力，从而扩展了标准的应用的范围（如，通过包括支持更大范围的图像样点精度和更高解析度的色度格式来实现）。另外，定义了补充数据的新类型，更进一步扩展视频编码标准的适用性。最后，对已印刷版本中的若干错误进行了修正。本版本除了增强了视频编码能力以外，还用来和联合研发的ISO/IEC 14496-10标准在技术上保持一致。 ITU-T H.264 建议书的勘误表1修改和更新了一些次要的方面，使之与于2005年4月通过的联合开发并且技术一致的ISO/IEC 14496-10的最新版本的文本相一致。它还改正了一些次要错误，进行了一些必要的澄清，并且定义了三个前面预留的幅型比标识符。 本版本包括2005年3月通过的文本以及在2005年9月通过的勘误表1。
