本标准规定了包含视频、音频和相关数据的数据块的内容、格式和记录方法，这些数据块在12.65毫米（0.5英寸）磁带上形成螺旋记录。此外，本标准规定了纵向记录的内容、格式和记录方法，该纵向记录包含与螺旋记录相关联的扫描头的跟踪信息，以及纵向线索音频、时间和控制码轨迹。一个视频通道和八个独立的AES3音频数据通道1）以数字格式记录。这些AES3数据通道中的每一个都设计为能够独立编辑。注1？在本标准全文中，“AES3音频数据”应缩写为“音频数据”，并表示AES中的数字化音频和数据- 3.格式。视频频道在帧频率为29.97 Hz的525线系统（以下称为525/60系统）和帧频率为25.00 Hz的625线系统（以下称为625/50系统）中记录和再现分量电视信号。

This standard specifies the content, format, and recording method of the data blocks containing video, audio, and associated data which form the helical records on 12.65-mm (0.5-in) tape. In addition, this standard specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records, and also the longitudinal cue audio, and time and control code tracks. One video channel and eight independent AES3 audio data channels1) are recorded in the digital format. Each of these AES3 data channels is designed to be capable of independent editing. NOTE 1 ¿ Throughout the text of this standard, the expression ¿AES3 audio data¿ shall be abbreviated to ¿audio data¿ and represents digitized audio and data in AES-3 format. 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 25.00 Hz (hereafter referred to as the 625/50 system).
