36、TE RECORDING FORMAT USING 12,65 MM MAGNETIC TAPE AND INCORPORATING MPEG-2 COMPRESSION FORMAT D-10 1 Scope This standard specifies the formatting for the recording of data blocks containing MPEG-2 compressed video, multiple channels of AES3 audio and associated data which form helical records on 12,6

37、5 mm tape in cassettes. This standard also defines the helical track record parameters, the content and format of the longitudinal records and the cassette physical specifications. The compressed video uses the MPEG-2 compression which is defined by ISO/IEC 13818-2 with constraints as defined by Ann

38、ex F. The compressed video channel supports frame frequencies of 30/1,001 Hz (hereafter referred to as 525/60 system) and 25 Hz (hereafter referred to as 625/50 system). 2 Normative references The following referenced documents are indispensable for the application of this document.
