Recording sound on cinema films by compact disc
Device for controlling the projection of sound films by the reproduction of sound associated with the images, using a compact disc type of laser reader or any other type. With the recording of all or part of the related sound being carried out by the compact disc system, complete control of the reading (starting up, compensation for cuts, interruption and finishing) is achieved by reading the digital data written on the conventional sound track and by the installation on the reader assembly of a matched interface, controlled by the programmable internal microprocessor and associated with a decoding module.
