标准摘要
[中文适用范围]: 此建议|国际标准规定了数字存储介质和数字视频通信的图像信息的编码表示,并规定了解码过程。 该表示支持恒定比特率传输、可变比特率传输、随机访问、频道跳变、可扩展解码、比特流编辑,以及快进播放、快退播放、慢动作、暂停和静态图片等特殊功能。 此建议|国际标准向前兼容 ISO/IEC 11172-2,向上或向下兼容 EDTV、HDTV、SDTV 格式。 [外文原描述]: ISO/IEC 13818-2:2013 specifies a coded representation of video data and the decoding process required to reconstruct pictures. It provides a generic video coding scheme which serves a wide range of applications, bit rates, picture resolutions and qualities. Its basic coding algorithm is a hybrid of motion compensated prediction and discrete cosine transform (DCT). Pictures to be coded can be either interlaced or progressive. Necessary algorithmic elements are integrated into a single syntax, and a limited number of subsets are defined in terms of Profile (functionalities) and Level (parameters) to facilitate practical use of this generic video coding International Standard.
