ITU-T H.265 (04/2013)

高效率视频编码

ITU-T H.265建议书是现有视频编码标准（ITU-T H.261、ITU-T H.262、ITU-T H.263和ITU-T H.264）的演变，是针对电影压缩需求与日俱增的情况而编制的，用于互联网流式传输、通信、视频会议、数字存储媒体和电视广播等不同应用，还计划将编码视频表达方式灵活地应用于广泛多样的网络环境。本建议书 | 国际标准的使用可使视频转换成一种计算机数据，并存储于多种存储媒介，通过现有和未来的网络传输和接收，并通过现有和未来的广播信道发布。本建议书是与ISO/IEC JTC 1/SC 29/WG 11 (MPEG)共同起草且技术上与ISO/IEC 23008-2保持一致。
