Problems solved by technology

Therefore, it is important to secure the sending of the video track between the producer and the dubbing studio or to limit the value of the video track
One approach consists in using secure transport, but this proves expensive if the dubber performs the dubbing in the country where the language is spoken

Embodiment Construction

[0023] figure 1 The basic layout of an audio-visual document producing apparatus according to a preferred exemplary embodiment of the present invention is illustrated. The production device 1 comprises a central unit 1.1, a program memory 1.2 comprising operating programs, a database 1.3 comprising audio and / or visual content and a two-way communication interface 1.4 enabling downloading and sending of audio and / or visual content via a network 1.5. The network 1.5 may be of the Internet type.

[0024] The program memory 1.2 contains modules for making audiovisual files based on various shots (or "cuts"), modules for analyzing the files stored in the database 1.3 and at least one blurring module intended to degrade the image in some places . The analysis module, by virtue of the properties that may be present, allows to more easily determine the presence of some characteristic of the image on the one hand (typically actors' heads, their faces or their lips) and on the other h...

Abstract

The invention relates to a method for adding voice content to an audiovisual document. A video document is first received in a device for reproducing and recording sound signals. The received video content includes degraded areas and at least one non-degraded area that is perfectly visible to a user upon the reproduction of said document. Said user reads a text that is recoded in the device. The text is read at predetermined times during the reproduction of the received video content by using visual elements appearing in the non-degraded areas. A complete video document is generated by assembling the audiovisual document and at least one recently-created sound content.

Description

technical field [0001] The invention relates to a method for adding new sound content to a video file subject to security constraints and a device implementing the method. Background technique [0002] Many forms of piracy of audiovisual files exist today. Cameras installed in theaters make it possible to produce illegal copies of projected files. Illegal copies are then found on the Internet or on commercially available media such as CDs or DVDs. These copies cause damage to the film industry and loss of income to producers of audiovisual documents. Sophisticated techniques are envisioned for preventing or detecting such behavior. For example, the producer incorporates into the image of the document to be projected a mark that is not detectable to the human eye but perceptible to the device. This marking is visually rendered during rendering of the file, thereby significantly degrading the file and greatly limiting its value. [0003] In order to avoid illegal copying,...
