An image processing device processes a first sub-image of an image split into sub-images. Each sub-image is displayable by a display device. The image processing device is associated with a first display device and connects to a source device through a first network and to another image processing device through a second network. The image processing device includes first and second receiving units and a generating unit. The first receiving unit receives the first sub-image from the source device via the first network. The second receiving unit receives, via a second network, at least one part of at least one second sub-image to be displayed by another display device, wherein the received at least one part is adjacent to the received first sub-image. The generating unit generates a first clustered sub-image to be displayed by the first display device, based on the received first sub-image and adjacent part.

The present invention relates to a method for managing communications in a wireless communications network having a mesh or 'relay-based' communication mode operating according to a relay scheme. The network includes network devices defining transmission links between them. The method includes initially detecting a mobile obstacle within the network coverage area; dynamically tracking the detected obstacle by iteratively determining a monitoring area including the detected obstacle; selecting, from the transmission links, a subset of monitoring links belonging at least partly to the monitoring area and monitoring a perturbation level of the selected monitoring links to determine movement of the mobile obstacle in the coverage area; and dynamically adapting the relay scheme of the network based on the belonging or not belonging of the transmission links between network devices to the selected subset.

A method is proposed for setting up a communications path between a first communications sub-network and a second communications sub-network by means of an intermediate communications sub-network in an extended communications network. More specifically, to set up the communications path, said intermediate sub-network comprises at least two tunnel end-points and an input tunnel end-point of said intermediate sub-network which performs the following steps of: receiving, from a tunnel of said input tunnel end-point, a relay activation message to set up said path, said message referring to a local relay involving said input tunnel end-point; determining, from said relay activation message, an output tunnel end-point of said intermediate sub-network involved in the local relay; activating the local relay for a part of said path between said first sub-network and said second sub-network transmitting the relay activation message to said output tunnel end-point.

A method is proposed for balancing a latency of transmission of data content in a communications tree in a synchronous communications network, the communications tree comprising a root node on which a junction terminal is connected, the communications tree comprising leaf nodes on which terminals are connected, the root node and the leaf nodes being interconnected by intermediate nodes, the nodes being interconnected by links. The method comprises determining, for each node of the communications tree, a maximum value of latency associated with each path going from said node up to leaf nodes in a direction opposite to the junction terminal, and applying to each link at a node, the link running from the node in the direction opposite to the junction terminal, a supplement of latency balancing that corresponds to a difference between a maximum value of latency of each link and a maximum value.

A method for managing frames in a global-area communications network comprises a plurality of sub-networks linked to one another by tunnels at the ends of which there are tunnel endpoints, at least one of the sub-networks comprising at least one source device connected to one of said tunnel endpoints through said sub-network. When a given tunnel endpoint receives from a local sub-network, to which said given tunnel endpoint is connected, a frame sent out by a source device in the global-area network, the given tunnel endpoint performs the following steps: obtaining, from said frame, an address of the source device; verifying that the obtained address is included in a first list of addresses comprising addresses associated with source devices connected to remote sub-network or sub-networks distinct from the local sub-network; and in the event of positive verification, discarding said frame.

A method for insertion of information for control of broadcasting of a data stream in a heterogeneous network, the network including an entry sub-network conveying first packets and a basic network conveying second packets. The sub-network is connected to the basic network by an entry node forming the second packets. The node receives first packets from the sub-network, associates an access level with each first packet from a plurality of access levels, as a function of a predetermined policy of association, forms each second packet by enclosing at least a first packet or part thereof into the second packet, the enclosed first packets or part thereof being associated with a same access level, for each second packet, inserts, into a field of the second packet representing the broadcast control information, the same access level, and transmits the formed second packets into the basic network.
