本标准规定了在19 mm D-1型电视数字元件记录中，在包含视频、音频和相关数据的磁带上形成螺旋记录的数据块的内容、格式和记录方法。此外，本文件第6条规定了纵向记录的内容、格式和记录方法，纵向记录包含与螺旋记录相关的扫描头跟踪信息。SMPTE 224M中规定了轨道尺寸和位置。本标准适用于在525线电视系统中运行的录像机，其标称帧频为29.97 Hz，符合ITU-R BT.601。录制一个视频通道和四个独立的音频通道。音频通道按照ANSI S4操作。在48 kHz采样频率下为40。图1显示了记录器中涉及的流程框图。

This standard specifies the content, format, and recording method of the data blocks forming the helical records on the tape containing video, audio, and associated data in 19-mm type D-1 television digital component recording. In addition, clause 6 of this document specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records. Track dimensions and locations are specified in SMPTE 224M.The standard applies to recorders operating in the 525-line television system with a frame frequency of 29.97 Hz nominal and in accord with ITU-R BT.601. One video channel and four independent audio channels are recorded. Audio channels operate in accord with ANSI S4.40 at a 48-kHz sampling frequency. Figure 1 shows a block diagram of the processes involved in the recorder.
