A media stream is transmitted from a server device to a client device. The client device () transmits set-up request messages (), discovery messages () and a play command message (). The server receives versions of the set-up request messages), the discovery message () and the play message () with matching identifier in the payloads if the messages. The server device () receives the discovery messages () on a predetermined port and stores information recording that the discovery messages () have been received, at least when no corresponding set-up request messagehas been received before. The server device () compares the identifiers from the received set up request message () and the discovery message () according to the information recording reception, at least when the discovery message () has been received before the set-up request message (). The server device () selects transport parameters for transmission of the media stream responsive to detection that the first and second identifier have matching values, the selected transport parameters being based on data from said set-up request message () and a port identification from a source field of the discovery message (). The media stream is transmitted in accordance with the selected transport parameters to the client device () addressed to the port determined from the source field of the discovery message ().

A wireless communication system including a cellular access network connected to a cellular network core, the cellular access network including cellular base stations adapted to exchange data with terminals on physical channels, called coordinated access channels, each cellular base station serving a geographical area, all the geographical areas served by the cellular base stations forming a geographical region. The wireless communication system includes random access base stations serving the geographical region, each random access base station being adapted to receive data emitted by terminals on a permanent physical channel, called random access channel, the permanent physical random access channels of the random access base stations using the same radio resources throughout the geographical region.

A method for controlling, via a terminal, a standby mode of a first communication module of the terminal. The first communication module exchanges data with a first wireless access network. The terminal includes a second communication module, which exchanges data with a second wireless access network. The second communication module has a maximum data rate that is lower than a maximum data rate of the first communication module. The terminal belongs to a group of terminals sharing a set of one or several identification codes for connecting to the first wireless network. When the first communication module is in standby mode, the second communication module listens to a downlink between the second wireless access network and the terminal. The first communication module is activated and connects to the first wireless network using the indicated identification code in the activation request received from the server.

A network client device is disclosed having a media streamer for processing a media stream received at a first port of a client device. Further included is a setup controller configured to transmit a set-up request message and a discovery message without waiting for acknowledgement of reception of the set-up request message before transmission of the discovery message, from a second port and the first port respectively, to predetermined ports of a server device.

The first communication module is configured to exchange data with a first wireless access network. The terminal includes a second communication module, which is configured to exchange data with a second wireless access network. The second communication module has a maximum data rate that is lower than a maximum data rate of the first communication module. When the first communication module is in sleep mode, the second communication module is configured to listen to a downlink between the second wireless access network and the terminal. When the terminal receives an activation request from the server via the second communication module, the first communication module is activated.

A method for analyzing frequency resources within a predetermined multiplexing band. For at least one base station, capabilities for detecting uplink messages respectively in different frequency sub-bands within the multiplexing band are estimated. For each frequency sub-band, a predetermined service quality criterion is assessed depending on the detection capability estimated for the frequency sub-band. A spectral map of service quality for the base station is transmitted. The spectral map is representative of the frequency sub-bands for which the service quality criterion has been verified and the frequency sub-bands for which the service quality criterion has not been verified.

Method for analyzing frequency resources and selecting transmission frequency in a wireless communication system

A method for transmitting broadcast signals from a group of base stations to terminals of a wireless communication system. Each base station having a coverage area. The coverage areas of the base stations of the group are distributed geographically such as to serve a geographical area. Since the broadcast signals are of limited duration and are transmitted in a frequency band used by all of the base stations of the group, the base stations of the group are time-synchronized in relation to one another. The broadcast signals from the base stations of the group are time-multiplexed. In addition, the wireless communication system has multiple geographical regions. Each region includes multiple groups of base stations), and the broadcast signals of different geographical regions are time-multiplexed.

The present invention relates to a method of decoding audiovisual data allowing to process, on the basis of an improved syntactic language, distincts elements of a scene as objects for which individual animations, particular interactions user/elements, and specific relations between said elements and the defined animations and/or interactions can be provided, said description being organized in a hierarchical tree also comprising transversal connections provided both for embedding bidimensional and/or tridimensional objects in each other and optionally controlling the rendering of scenes from various view points, while maintaining a control of all related actions both in the embedded objects and/or scenes and in the original ones.

Audiovisual data decoding method

In a broadcast application on a client-server network the streaming is emulated of animation data over the Internet to a large number of clients. The animation is considered a sequence of states. State information is sent to the clients instead of the graphics data itself. The clients generate the animation data itself under control of the state information. The server and clients communicate using a shared object protocol. Thus, streaming is accomplished as well as a broadcast without running into severe network bandwidth problems.

The server and clients communicate using a shared object protocol. Thus, streaming is accomplished as well as a broadcast without running into severe network bandwidth problems. This approach is used to map a real life event, e.g., a motor race, onto a virtual environment in order to let the user participate in a virtual race against the real life professionals, the dynamics of the virtual environment being determined by the state changes sent to the user.

A device for the non-destructive testing of hollow tubular objects using ultrasound. The device has a stage for transmission of ultrasonic waves and a stage for reception of ultrasonic signals. The transducer structure includes an assembly of annular individual transducers which are juxtaposed in a coaxial fashion or, in an alternative embodiment, two annular arrays, each of which consists of an assembly of juxtaposed individual transducers. Moreover, the stages for the transmission and reception can simultaneously select, from the assembly or from each of the assemblies, at least one transmitter transducer (2(I)) and at least one receiver transducer (2(j)). This selection forms a transducer sub-assembly which can be displaced at will by electronic scanning along the axis of the succession of transducers in order to enable optimum execution of the so-called TOFD testing method.
