Abstract: A method for processing a sequence of digital images. The method includes, for a current group: a) forming a main group including original images partitioned into spatial areas and including a watermarking zone; b) obtaining a main bitstream representing an area-based encoding of the images of the main group, in which for an area other than the watermarking area, the pixels of that zone are not predicted with reference to pixels in the watermarking area; c) for the watermarking area: forming a secondary group of images having the same temporal dimension as the main group and spatial dimensions equal to those of the watermarking area, inserting a first watermarking information value into the secondary group, and obtaining a first secondary bitstream representing images of the encoded secondary group including the first watermarking information value; and d) transmitting the main and first secondary bitstreams in the telecommunication network to a client.

Abstract: Processing a request for delivery of data sent by a customer terminal to a remote server via a telecommunication network. The terminal accesses the network by at least two links of distinct access types. The data is encoded in a stream with a predetermined bit rate, which is cut into segments. Processing includes, for a segment of the stream: determining a sub-segment size based on the number of links and a size of the data stream to be delivered; calculating a partitioning of the segment into sub-segments according to the set size and a distribution of the sub-segments on the plurality of links, according to a scheduling of the sub-segments in the partitioning and a time constraint; and sending a plurality of sub-segment transmission requests to the server over the plurality of links, each request including an identifier of the segment and indexes of a sub-segment start and end.

Abstract: A method for processing encoded data representative of a sequence of digital frames for transmission to client equipment by a client via a communication network. The method includes the following steps, implemented following encoding of a current frame of the sequence: obtaining encoded data representative of the current frame; extracting at least one information representative of an encoding structure of the current frame; updating a transport container by inserting encoded data representative of the current frame into a predetermined location; updating a metadata container, by inserting the at least one information of encoding structure and information representative of the location of the encoded data in the transport container; and transmitting to the client equipment the second container. Upon receipt of a request from the client equipment, including a information representative of the location of the data, transmitting the encoded data of the transport container corresponding to the location.
