指定数字存储媒体的视频编码表示和解码过程。主要适用于支持高达约1.5 Mbit/s的连续传输速率的数字存储介质，例如光盘、数字音频磁带和硬盘，以及具有约288行352像素和24 Hz至30 Hz左右的图像速率的非隔行视频格式。然而，由于采用了通用的方法，它可以被更广泛地使用。

Specifies the coded representation of video for digital storage media and the decoding process. Is primarily applicable to digital storage media supporting a continuous transfer rate up to about 1,5 Mbit/s, such as compact disc, digital audio tape, and magnetic hard disc, and for non-interlaced video formats having approximately 288 lines of 352 pels and picture rates around 24 Hz to 30 Hz. Nevertheless it can be used more widely than this because of the generic approach taken.
