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 method incudes the preliminary steps of producing a map of a room, wherein one or more sound sources are located; acquiring acoustic features of the walls; performing a simulation, by using the map and the acoustic features, of a propagation in the room of sounds emitted by the sound sources; producing the reference audio parameters; the method further comprising the operational steps of: determining a current position of a user in the room; playing an audio signal back by the sound sources by applying the current audio parameters obtained from the reference audio parameters, and which depend on the current position.

Abstract: The method for positioning an anchor B in a system RA defined by an anchor A, the anchor A and the anchor B being outside of UWB range from one another, but in Wi-Fi range, the positioning method using mobile equipment (2) comprising a UWB communication module (5) and a Wi-Fi communication module (10). The measuring method include the steps of: evaluating, by using UWB signals, a position PMA of the mobile equipment (2) in the system RA; evaluate a position PB of the anchor B, by using UWB signals, if the mobile equipment (2) is located in UWB range of the anchor B, or by alternatively using Wi-Fi signals; deduce from the position PMA and from the position PB, a position PBA of the anchor B in the system RA.

Abstract: A method for balancing audio channels includes an acquisition phase comprising the step of acquiring calibration gains making it possible to balance the audio channels in a calibration position. The balancing method further includes an operational phase comprising the steps, performed in real time, of: implementing UWB geolocation to define a current position (COUR) of a mobile apparatus comprising a UWB communication component; for each audio channel, producing an operational gain which is dependent on the current position (COUR) of the mobile apparatus, on the calibration position and on the calibration gain that is associated with said audio channel, the operational gains making it possible to balance the audio channels in the current position; applying, to each audio channel, the operational gain associated with said audio channel.

Abstract: Method for the remote recording of a video program received in the form of a binary stream by at least one receiver, referred to as a recording receiver, having to record the video program on a remote server using a communication network. The method is implemented by each recording receiver and comprises, for each recording receiver, steps of obtaining (3051) a compression factor of the video program, of dividing (3054) the binary stream into a set of successive portions according to the compression factor obtained, of determining (305) a subset of portions to be transmitted to the remote server from all the successive portions according to an offset value and the compression factor, the offset value being a remainder of an integer division of a random number determined to find the recording receiver by the compression factor, and of transmission of the portions of the subset of portions determined to the remote server.
