Abstract: The invention relates to a method and a device for communication between a communication system of a vehicle (10) and a public land mobile network (100). To this end, a first piece of information representative of the current power consumption of the vehicle (10) is received; a second piece of information representative of an amount of electricity available in the vehicle (10), for example in the battery of the vehicle (10), is received; and a third piece of information representative of the target time during which the vehicle (10) wishes to remain connected to the network (100) is received. Based on the first, second and third pieces of information, the network (100) determines which power saving mode should be assigned to the communication system of the vehicle (10) so that the vehicle can maintain a connection to the network (10) for the desired time.

Abstract: The invention relates to a method and device for controlling a vehicle communication device (11). To that end, information on the temperature in the communication device (11) is received. This temperature information is, for example, received from a temperature sensor integrated into the communication device (11). Control parameters for functions performed by the communication device (11) are then controlled, for example in order to deactivate all or part of one or more functions, according to the one or more temperatures received.

Abstract: The invention relates to a method and a device for transmitting data for a vehicle, in particular in a V2X communication network. For this purpose, a data frame (2) is transmitted in a vehicle-to-everything (V2X) communication mode. The frame (2) advantageously comprises a series (200) of a plurality of identical and consecutive data packets (21 to 24) in the data frame, each packet (21 to 24) comprising the same set of identical data.

Abstract: A communication device for a vehicle comprises a plurality of communication means and a rule base. The communication device is designed to determine a communication means to use using said rule base. The communication device is further designed to: check with a remote server as to whether an update of the rule base is available, download the rule base update, and update the rule base using the downloaded rule base.

Abstract: A device (D1) is dedicated to the processing of video images which are intended to be transmitted to a receiver (R) so as to be used to construct synthesis images to be displayed. This device (D1) is devised, in the presence of a video image acquired consisting of video image data, so as to construct a processed image by replacing in this acquired video image some of its video image data by a control message which contains at least one group of control data, of nonvideo type and defining information which is intended to be used by the receiver (R) to construct a synthesis image to be displayed on the basis at least of the remaining video image data, after the replacement, in the processed image.

Abstract: This device in which the network includes a transmission cable (4) fitted with a pair of conductors (2, 3), is characterized in that each conductor (2, 3) of the cable is linked at each of its ends to a terminal of a resistor (9, 10) whose value is equal to half the value of the characteristic impedance of the cable (4) and the other terminal of which is linked to a voltage source (11, 12).
