  • High fidelity reproduction device for cinema sound
    Patent number: 5450146
    Abstract: Dynamic range and passband problems in cinema sound transmission are solved by using a laser disk (9) read by a laser disk player (10, 11, 12) synchronized (14) with the original sound track of the film. Problems relating to splices in the film are solved by reading the sound in advance, in storing it in a memory (13), in reading it back subsequently from the memory, and, where necessary, in causing the memory read back system to jump (24) in order to avoid reproducing sound that corresponds to images that have been removed from the film.
