How does DTS 70mm work?
The DTS 70mm digital sound format generally functions the same as the DTS 35mm but with some important distinctions. Films released in the DTS 70mm format do not have the standard (analog 6-track sound) magnetic striping. The DTS timecode is written outside the sprocket holes where the 70mm track-two magnetic striping normally resides. This allows the usable picture area to be increased to fill the space used by the inner magnetic stripes. The size of the timecode on a DTS 70mm print is huge. At 30 mils wide, it is easily visible to the naked eye. Damage by normal scratches does not affect the reader’s ability to scan timecode. Since the frame size of each picture cell is larger than 35mm, the playback offset must be adjusted for proper play back sound synchronization. Since the magnetic sound stripe is not on the film, DTS 70mm prints cannot use analog sound for backup. Instead, installing a second DTS player is recommended to ensure 100% fail-safe operation.
