specifies the track content, format, and recording method of the data blocks containing compressed video, AES3 audio data, and associated data which form the helical records on 12,65 mm tape in cassettes. This standard supports recording of source picture formats using 1920 1080 pixels with the 4:4:4 and 4:2:2 sampling structure specified in SMPTE 274M at the frame rate of 23,98 Hz, 24 Hz, 25 Hz and 29,97 Hz, and using 1280 720 pixels with the 4:2:2 sampling structure specified in SMPTE 296M at the frame rates of 50 Hz and 59,94 Hz (see note). This standard also supports recording of 12 channels of AES3 audio data and 3 lines of uncompressed blanking interval data. This standard includes packetizing and shuffling operations supporting picture compression using the DCT and DPCM encoding methods defined by ISO/IEC 14496-2 (MPEG-4 simple studio profile).
