适用范围：This part of IEC 61834 specifies the content, format and recording method of the data blocks forming the helical records on the tape containing audio, video, and system data. It describes the specifications for the 525-line system with a frame frequency of 29,97 Hz (hereinafter referred to as 525-60 system) and 625-line system with a frame frequency of 25,00 Hz (hereinafter referred to as 625-50 system) which are not included in part 1. One video channel and two independent audio channels are recorded in the digital format. Each of these channels is designed to be capable of independent editing. The video channel records and reproduces a component 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 areas as described in 4.3.2 in part 1 and AP1 = AP2 = AP3 = 000b.
