IEC 62330的本部分规定了包含第2部分“音频”中定义的高清压缩视频数据和相关数据的数据块的内容、格式和记录方法，这些数据块形成了IEC 61835中规定的盒式磁带中12.65 mm（0.5 in）的螺旋形记录。 此外，本标准规定了纵向记录的内容、格式和记录方法，其中包含与螺旋记录相关联的扫描头的跟踪信息，以及纵向提示音频、时间和控制代码。 一个高清压缩视频数据的视频通道和四个独立的音频通道以数字格式记录。这些频道中的每一个都被设计为能够独立编辑。 高清压缩视频数据来自以下高清视频信号: 1080线/59,94赫兹场频交错系统 720线/59,94赫兹帧频累进系统

This part of IEC 62330 specifies the content, format, and recording method of the data blocks containing HD compressed video data defined in part 2, audio, and associated data which form the helical records on 12,65 mm (0,5 in) tape in cassettes as specified in IEC 61835. 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. One video channel of HD compressed video data and four independent audio channels are recorded in the digital format. Each of these channels is designed to be capable of independent editing. The HD compressed video data are derived from the following HD video signal: 1080 line / 59,94 Hz field frequency interlace system 720 line / 59,94 Hz frame frequency progressive system
