Abstract: A method for filtering a sound signal acquired by a voice recognition system is proposed wherein the filter used to delete the unwanted sound signal is based on a noise model created from a history of preceding acquisitions of the sound signal. The method is based on the history for predicting the characteristics of the signal in the course of acquisition and relies on this prediction to establish the noise model used by the filtering function.

Abstract: A wireless communication system includes a first access point managing a first wireless local area network and at least one second access point managing at least one respective wireless local area network. A CSMA/CA procedure is employed. The first access point is involved in a real-time sensitive transmission. Each access point implements an energy detection mechanism and a preamble detection mechanism in the context of the CSMA/CA procedure. The energy detection mechanism is implemented for accessing the primary channel and for accessing each secondary channel. The preamble detection mechanism is implemented for accessing the primary channel and optionally for accessing each secondary channel. A decision making unit instructs the first access point and each second access point to use the same primary communication channel. This improves the conditions under which the real-time sensitive transmission takes place.

Abstract: A method is directed to recovering a target file by an audio/video receiving equipment, the audio/video receiving equipment including at least two communication interfaces, including a first communication interface able to receive broadcast data and a second communication interface able to establish a bidirectional dialog with a server. The method makes possible to make data available simultaneously: in the “normal” direction, from the beginning to the end, on an IP interface via a file server (HTTP/FTP/etc.); in the “reverse” direction, from the end to the beginning, on a broadcast interface via a DSM-CC carousel, referred to as a dedicated channel. Thus the audio/video reception equipment can efficiently recover the data by simultaneously using two communication interfaces including at least one unidirectional interface.

Abstract: In order to reduce the large volume of data transmitted over a network, immersive videos are frequently represented by a multiple versions, each version being optimised in terms of quality for a point of view on the immersive video, the immersive video parts not representing the point of view for which the version was optimised being of lower quality. In this context, when a user using suitable viewing equipment views the immersive video, he must change version whenever he changes point of view. Each version is generally stored on a server relatively distant from the viewing equipment, which may give rise to latencies in the reception of a new version following a change of point of view. This latency time is reduced by allowing a node in the intermediate network between the server and the viewing equipment to transmit each version to the equipment in place of the server.
