Abstract: A transmission of a digital content to a user terminal is managed by a network comprising a service subnetwork adapted for providing the terminal with a service token, and a digital contents distribution subnetwork which includes a control part and a transmission part. The control part of the distribution subnetwork receives a request from the user terminal for a digital content, indicating a service token. Next, if the service token is recognized as valid, an address relating to the distribution subnetwork is determined and a session token associated with said address is generated. A message indicating said address and the session token associated with said address is then transmitted to the user terminal.

Abstract: A method and device are provided for measuring impulse noise in a signal. The method includes: measuring at least one first signal; converting the first signal in the frequency domain; defining a variable-frequency triggering threshold on the basis of stationary characteristics of the first signal; measuring a second signal; converting the second signal in the frequency domain; storing the second signal when the second signal reaches or passes the triggering threshold; and high-pass-filtering the stored signal.
Abstract: A technique of controlling access by a client entity to a service in a communications network. Processing modules are interconnected in the network in order to supply the service to the client entity. A processing module implements an individual function of a chain of individual functions associated with the service. The access method includes the following steps implemented by an access control device associated with an access node giving access to the service, the device being referred to as a main device: receiving a chain of processing modules from the access node; sending, to a secondary access control device associated with a processing module of the chain, a request to access the processing module under consideration, the request including an access token negotiated between the main device and the client entity; receiving a response to the access request from the secondary device; and notifying the access node of the response.

Abstract: A data reception device in a communication network using a plurality of radio frequency channels. At least two adjacent radio frequency channels are concatenated so as to form a concatenated channel. The device is configured to receive “received” data transmitted in at least one radio frequency channel of the concatenated channel; transpose the received data at an intermediate frequency, thus outputting data at an intermediate frequency; filtering the data at the intermediate frequency with a filter including at least two separate filtering channels, each filtering channel including a band-pass filter, the frequency band of which corresponds to the frequency band of a separate radio frequency channel of the concatenated channel such that the total frequency band of the filters is equal to the frequency band of the concatenated channel; activating at least one of the filtering channels; and recombining data from the filtering channels.
Abstract: The invention relates to transform coding/decoding of a digital audio signal represented by a succession of frames, using windows of different lengths. For the coding within the meaning of the invention, it is sought to detect (51) a particular event, such as an attack, in a current frame (Ti); and, at least if said particular event is detected at the start of the current frame (53), a short window (54) is directly applied in order to code (56) the current frame (Ti) without applying a transition window. Thus, the coding has a reduced delay in relation to the prior art. In addition, an ad hoc processing is applied during decoding in order to compensate for the direct passage from a long window to a short window during coding.
