本标准规定了包含视频、音频、， 以及在盒式磁带中12.65毫米磁带上形成螺旋记录的相关数据。此外，它还指定了 包含车辆跟踪信息的纵向记录的内容、格式和记录方法 与螺旋记录、提示音频和控制轨迹相关的扫描头。一个视频通道和四个独立的音频通道以数字格式记录。每一个 频道可以独立编辑。视频频道以帧的形式在525线系统中记录和再现分量电视信号 频率为29.97 Hz（以下简称525/60系统）和625- 带框架的直线系统 频率为25赫兹（以下简称625/50系统）。帧内比特率降低适用于录制前的视频数据。

This standard specifies the content, format, and recording method of the data blocks containing video, audio, and associated data that form the helical records on 12.65-mm tape in cassettes. In addition, it specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records, cue audio, and control tracks.One video channel and four independent audio channels are recorded in the digital format. Each of these channels is capable of independent editing.The video channel records and reproduces a component television signal in the 525-line system with a frame frequency of 29.97 Hz (hereafter referred to as the 525/60 system) and the 625-line system with a frame frequency of 25 Hz (hereafter referred to as the 625/50 system).Intraframe bit-rate reduction is applied to video data prior to recording.
