METHOD FOR MANAGING COMMUNICATIONS IN A COMMUNICATION NETWORK IMPLEMENTING AT LEAST ONE MOBILE INTERMEDIATE DEVICE, AND CORRESPONDING SYSTEM AND COMPUTER PROGRAM
A method for managing communications implementing a mobile intermediate device generating a radio beam that covers a radio cell, implementing for a data stream of the radio beam: obtaining the number of individual phases each associated with a target rate in the stream for transmissions from the mobile intermediate device to the radio cell: detecting a start of a connection of a user device present in the radio cell to a data server via the mobile intermediate device; if an individual phase is available for the stream: transmitting connection start data from the data server between the mobile intermediate device and the user device at the target rate of the individual phase until a stop criterion; if no individual phase is available for the stream: transmitting connection start data from the data server between the mobile intermediate device and the user device at a rate lower than the target rate.
A method for automatically reading a continuous text composed of several groups of words, as well as a corresponding computer program, storage medium, automatic reader, and user terminal. The method includes providing, in real time, a sound stream corresponding to the text. The sound stream starts from a selected group of words, also called second group of words, selected in the text as a function of at least one result of a real-time analysis of captured speech. The result of the analysis is indicative of a first group of words currently being verbalized by a speaker, the first group of words and the second group of words being different groups of words.

A decoding method implemented by a decoding device. The decoding method includes: obtaining a data stream, including a plurality of identifiers, a sequence of binary elements and an indicator indicating a start of the sequence of binary elements within the data stream; and decoding the obtained data stream into a sequence of data of respective predetermined types. The decoding includes: obtaining at least one piece of data of the sequence of data by: determining a context based on an identifier, from among the plurality of identifiers, that is associated with the respective type of the respective piece of data; identifying the start of the sequence of binary elements from the indicator; and decoding a part of the sequence of binary elements by using an entropy decoder receiving the sequence of binary elements as an input and parameterized in the determined context.
