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.

Abstract: Obstacle detection and characterisation method, including the steps of: acquiring a first distance measurement obtained from at least one inertial measurement produced by at least one inertial sensor of a mobile terminal, and a second distance measurement obtained from at least one time of flight measurement; evaluating a distance error representative of a difference between the second distance measurement and the first distance measurement; from the distance error, detecting the presence of an obstacle between the mobile terminal and the reference equipment, and determining one or more characteristics of said obstacle.

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 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.
