AUTOMATIC, ADAPTIVE SYSTEM AND METHOD FOR DIGITAL VIDEO STREAM ANALYSIS AND SCRAMBLING |
摘要 |
The invention relates to an automatic, adaptive method of scrambling digital video streams. The inventive method comprises the following steps consisting in: analysing the structure and the visual content of the digital video stream, and scrambling said digital video stream. The invention is characterised in that the scrambling step is controlled by an inference or decision-making engine which selects the scrambling tool(s) to be applied to the digital video stream from a library of possible scrambling tools, according to: the analysis step, digital information relating to the characteristics of the user for whom the resulting scrambled digital video stream is intended, and conditions for transferring the digital data resulting from said method in compliance with a database of pre-defined scrambling rules. |
