    • The invention concerns a method for texturing a mesh associated with a surface (1) representative of a scene captured in a plurality of images (110 to 150), wherein at least a mesh element (10) of said mesh is at least partially visible from at least two first images (110 to 140) of the plurality of images (110 to 150). As to reduce the amount of texture information associated to multi-views data representative of the scene, the method comprises: - for each first image (110 to 140), association of a first texture information with said mesh element (10), - projection of the first texture information in said at least two first images (110 to 140), - for each first texture information, estimation of an error information according to a comparison result between the projected first texture information and the texture information of said at least two first images (110 to 140), and - selection of one of the at least two first texture information according to said error information. The invention also concerns a corresponding computation unit.

    • The invention relates to a distribution method for a multimedia stream multiplexed of type MPEG2 "Transport Stream" noted "MPEG2-TS" via a network, the multiplexed multimedia stream comprising multimedia and signalling components, the components being divided into elementary packets of the multiplexed multimedia stream transmitted on at least one transport channel of the network. This method comprises a step of selection of elementary packets of the multiplexed multimedia stream incorporated in transport packets, each of the transport packets comprising at least one elementary packet and a part only of components, and each of the transport packets being transmitted on a transport channel. This method comprises a step of transmission of transport packets on each of the transport channels, comprising a step of definition of a first sequence number for each of the transport packets of each of the transport channels and a second sequence number for each of the elementary packets, the first sequence number being incremented for each of the transport packets, independently on each of the transport channels, the second sequence number being incremented for each of the elementary packets.

    • The present invention relates to a device (1) and a method for the preparation of data (21) to be sent as a continuous stream via a communication network. The device comprises means for obtainment (11) of the data originating from a database (2), which contains at least two data stream entities (Ej) for data associated respectively with different transmission throughputs (24), means of transfer (12) of these data to a sending system (3), means of connection (13) to one of these entities, and means of switching (14) of the means of connection from one of the entities to another. The preparation device also comprises means of regular addition (15) to the data transferred, of error correction codes (22). The means of switching switch from a first entity to a second entity of greater throughput, when this augmented data stream (DATA) reaches the sum of the sending throughput associated with the second entity and of an additional throughput (possibly zero) associated with an initial input of error correction codes of the second entity, and the means of addition reinitialize the addition of the codes to this initial input upon this switching. Application to streaming over IP network.
