適用范圍：This part of IEC 61834 specifies the content, format and recording method of the data blocksforming the helical records on the tape containing audio, video, and system data. It describesthe specifications for the 525-line system with a frame frequency of 29,97 Hz (hereinafterreferred to as 525-60 system) and 625-line system with a frame frequency of 25,OO Hz(hereinafter referred to as 625-50 system) which are not included in part 1. One video channeland two independent audio channels are recorded in the digital format. Each of these channelsis designed to be capable of independent editing. The video channel records and reproduces acomponent television signal in 525-60 and 625-50 systems.In this part, the data structure of a track is defined by APT = 000b which consists of four areasas described in 4.3.2 in part 1 and AP1 = AP2 = AP3 = 000b.
