摘要

"System for the processing of audiovisual content and type multimu00ecdias MPEG-2 in protected content of the same type".System for distribution of sequ00b3u00eancias video according to a format of the nominal flow, consisting of a succession of images, each image being composed of a series of blocks.And in which at least one of said blocks of one of these images is calculated for prognosis of movement with respect to the least one image of the reference.Being encoded in the flow that prognosis of movement with at least one motion vector. Before transmission to the client equipment.The flow is subjected to an analysis to generate a first modified flow, showing the shape of a nominal flow.And presenting images modified by replacement of certain data by data of the same type, and a second flow of a format random.Containing the substituted data and numerical information, capable of allowing the reconstruction of said flow modified and then transmitted separately.The two flows thus generated from the server to the destination equipment.In addition, a synthesis of a stream with the nominal format is calculated in the equipment of destination for the flow mentioned above, as a function of said first and said second flow stream.The invention is characterized by the fact that this modification consists in modifying at least one of said motion vectors.
