Abstract: A wireless communication system has an access point managing a first wireless local area network. To transmit the frame, the access point: obtains data to be transmitted in multicast mode; obtains data to be transmitted in unicast mode; and constructs a physical-layer header including: in a common signalling field, an identification of each channel resource intended to be used for making the frame transmission, whether this be for the data to be transmitted in unicast mode or in multicast mode; and, in each field in a series of specific signalling fields, information representing an association between a channel resource identifier used and a unique identifier of the destination concerned or group of destinations concerned. Thus each destination can determine each channel resource to listen to in order to receive the data that are addressed to it, whether this be in unicast mode or in multicast mode.

Abstract: A method for transmitting an immersive video between a network unit and an item of viewing equipment enables users to simultaneously view the immersive video which has a series of sets of images each composed of blocks of pixels. The immersive video is transmitted in a compressed form to each item of viewing equipment. For each set of images: information is obtained representing a point of view on the immersive video of each user; at least one privileged zone is determined corresponding to at least some of the points of view; for each image included in the set of images, a higher compression rate on average than a mean of the compression rates applied to the blocks of pixels belonging to a privileged zone is applied to the blocks of pixels not belonging to a privileged zone; and the set of images is transmitted to each item of viewing equipment.

Abstract: A pairing must be performed between a terminal, referred to as terminal to be paired, and a user account for a service implemented by at least one device connected to a first communication network. The terminal to be paired is connected via a second communication network to a gateway which interconnects the first and second communication networks by performing an address translation by means of a public address routable on the first communication network. A pairing device performs steps: of obtaining (3.2) said public address; of detecting (3.4) an access to said user account, said access being performed from another terminal (1.2), distinct from the terminal to be paired; of obtaining (3.5) the address of said other terminal; of pairing (3.6) the terminal to be paired and said user account if the address of said other terminal coincides with said public address.
