Abstract:
The mediation server comprises: a component configured to obtain an identifier of a first terminal seeking to obtain a location for a second terminal; a component configured to obtain a location for the second terminal and for validating that location; a component configured to obtain an authorization sent by said second terminal to communicate said location of the second terminal to the first terminal; and a component configured to communicate said location of the second terminal to the first terminal.
Abstract:
A method is provided for decoding a signal that represents at least one image. The method implements at least one iteration of the following steps, for at least one block of the image to be decoded: determining at least one selection parameter from at least one characteristic associated with at least one reference pixel of a reference region of the image, the reference region including at least one previously encoded/decoded block and/or at least one pixel predicted in a preceding iteration; selecting at least one pixel to be predicted in the block to be decoded from the at least one selection parameter; and for at least one selected pixel to be predicted, referred to as an anchor pixel, predicting the anchor pixel from at least one reference pixel, thereby outputting a predicted pixel.
Abstract:
A method for selecting data from a first electronic device for a second electronic device. The second electronic device includes an authentication module and is arranged to receive messages over a communication bearer, and transfer a received message to the authentication module when determining from an indication in the received message that the message is intended for the authentication module. The method includes receiving from the first electronic device the selected data, retrieving one or more commands associated to the selected data, generating using the selected data and associated command(s) a triggering message, the triggering massage including an indication that the triggering message is intended for the authentication module of the second electronic device for triggering the command(s) for the selected data, and sending the triggering message over the communication bearer to the second electronic device, thereby causing the authentication module to trigger the command for the selected data.
Abstract:
An error correction encoding device is provided that combines redundancy data with source data, said device including: at least three encoding stages and at least two permutation stages. Each encoding stage implements at least one set of three basic encoding modules, in which a first encoding stage receives said source data and a last encoding stage provides said redundancy data. Each encoding module implements a basic code and includes c inputs and c outputs, c being an integer. The permutation stages are inserted between two consecutive encoding stages and each permutation stage implements a c-cyclic permutation.
Abstract:
Digital data blocks are encrypted, each data block that is to be encrypted being associated with a time reference. A value of an initialization vector Vi and an encryption key K are defined. Then, a counter C is obtained for each data block to be encoded, by combining the time reference and the value of the initialization vector. A series of binary encryption elements is obtained via an encryption function taking the encryption key K and counter C as input parameters. The data block is then encrypted by combining it with the series of binary encryption elements.
Abstract:
A method and apparatus are provided for creating a pilot channel in an opportunistic radio communication system whose frequency spectrum comprises a set of frequency bands and for which system the successive frames of a radio communication channel are divided into time intervals. The method includes the steps of: opportunistically selecting a free frequency band from the frequency spectrum, so as to support the pilot channel; sending a beacon signal over at least one time interval of the successive frames of the pilot channel and probing the free frequency band over at least one time interval distinct from the previous one.
Abstract:
The invention relates to a passive optical network comprising an optical exchange linked by at least one optical fiber to at least one line termination device of said network, able to transmit a downlink optical signal phase-modulated in NRZ-DPSK format and to receive an uplink optical signal.According to the invention, said line termination device comprises means of converting the transmitted downlink optical signal phase-modulated in NRZ-DPSK format into an optical data signal amplitude-modulated in duobinary modulation format and means of generating an uplink optical signal phase-modulated in NRZ-DPSK format from the downlink optical signal phase-modulated in NRZ-DPSK format. The optical exchange is able to convert the uplink optical signal phase-modulated in NRZ-DPSK format into an optical data signal amplitude-modulated in duobinary modulation format.
Abstract:
A method for communication between a first web application associated with a first browsing domain and a second web application associated with a second browsing domain. The browser-implemented applications record data from a browser software module and prohibit access to data recorded for selective browsing domains. The browser concurrently displays at least two sub-pages of an initial web page, a first sub-page being used for displaying a user interface for the first web application, a second sub-page being used for displaying a user interface for the second web application being executed independently of the first web application. A first software module of the first web application stores data in a database which is read by a second software module of the second web application, the first and second software modules being associated with a third browsing domain.
Abstract:
A device for managing calls sent by a local terminal (T1-T5) includes: an interface (11-15) for communication with each of said local terminals (T1-T5) communications client modules (CL2-CL5) each able to set up a communications link of a communications service with a distant terminal (T6-T10) via a communications network; and routing means (18) for selecting, should one of the communications client modules receive an incoming call from a distant sending terminal, a local terminal able to receive said call and to redirect said call to the communications interface with the selected local terminal in order to set up a communications link between said distant sending terminal and the selected local terminal via the communications client module receiving the call.
Abstract:
A method for adapting the operation of an apparatus connected to a network deployed in an environment, including the steps of: collecting data relating to the environment from a plurality of sources; identifying usual environmental situations from an analysis of the collected data; detecting a deviation from at least one identified usual situation; and sending a control to the apparatus for adapting the operation thereof to the detected deviation.
