Abstract
The present invention relates to a processing device of a sequence of video images intended to be displayed by a digital cinema projection system, a projection system for the digital cinema and a video signal designed to be used by such a system. The use of an anti-camcorder method against copying films is generally carried out entirely in the digital cinema projection system. However, this method requires complex video processing and costly means in the projection system. According to the invention, it is proposed to carry out part of the video processing at the level of the post-production of the video sequence and to save the result of this 'pre-processing' in the form of metadata. The remaining part of the video processing is carried out from this metadata in the video projection system.
