Title:
DEVICE AND METHOD FOR SYNCHRONIZING AN AUDIO SIGNAL WITH A FILM
Document Type and Number:
WIPO Patent Application WO/2004/105034
Kind Code:
A1
Abstract:
The invention relates to a device for synchronizing an audio signal with a film, which consists of individual images, whereby each individual image has an illuminated time code. The inventive device comprises a unit (10) for detecting the illuminated time code for the sequence of individual images in order to obtain a recorded sequence of time codes. A time code generator (12) is also provided, which is designed for generating a sequence of synthesis time codes starting from a starting value. A decoder (14) is additionally provided in order to decode a time code of the detected sequence of time codes whereby furnishing the starting value for the time code generator (12). A detected time code and a corresponding synthesis time code are compared (16) in order to, in the event a phase deviation that exceeds a deviation threshold value has been established, subsequently manipulate (20) the synthesis time code for this individual code whereby modifying it with regard to the duration thereof. This synthesis time code is then fed to an audio processing unit (24) that is designed for providing, in a time-controlled manner, and in response to a detection of the synthesis time code for an individual image, the sampled values of the audio signal that are assigned to said individual image. A flexible system is hereby achieved via which any number of audio playback units can be synchronized with the film. In addition, the audio playback units, for synchronization purposes, are furnished with predefined synthesis time codes or with manipulated synthesis time codes.
