Временной код в цифровой форме печатается в области кинопленки между обычной аналоговой оптической фонограммой и кадровыми рамками, который экспонируют вместе с фонограммой, когда делают печать. Эта область частично проявлена повторно и обычно зарезервирована для отделения аналоговой фонограммы от кадровых рамок. Звук в цифровой форме для киноленты хранят в запоминающем устройстве архивных цифровых данных большой емкости и плотности. Временные коды, соответствующие известным положениям на пленке, считываются по мере воспроизведения пленки, и звуковые сигналы в цифровой форме для этих рамок в режиме ожидания передаются к буферной памяти данных быстрого доступа, в которой временно эти данные хранятся, прежде чем они преобразуются в аналоговый формат для воспроизведения в театре. Временный код считывается с помощью света, который поглощается красителями пленки, получаемыми при ее проявлении. Временное хранение звукового сигнала в цифровой форме в буферной памяти вмещает разрывы в пленке, смену проектора и различные схемы подтверждения достоверности временного кода, и позволяет источнику цифровых данных, в котором хранятся звуковые данные в цифровой форме, быть средством надежного хранения данных с медленным доступом, например магнитной лентой с информацией в цифровой форме.The time code is digitally printed in the area of the film between a conventional analog optical phonogram and frame frames, which are exposed together with the phonogram when they are printed. This area is partially re-developed and is usually reserved for separating the analog phonogram from the frame frames. Sound in digital form for films is stored in a storage device of archival digital data of large capacity and density. The time codes corresponding to known locations on the film are read as the film is played, and audio signals in digital form for these frames are transmitted in the standby mode to a buffer memory of quick access data in which this data is temporarily stored before they are converted to analog format for play in the theater. The time code is read using light that is absorbed by the dyes of the film obtained when it appears. Temporary storage of the audio signal in digital form in the buffer memory accommodates gaps in the film, a projector change and various time code validation schemes, and allows a digital data source in which audio data is stored in digital form to be a means of reliable data storage with slow access magnetic tape with information in digital form.
