Abstract: The invention concerns a method for transmitting a multicast stream in a data exchange network, at an access point (AP). It consists in analyzing (A) the multicast stream by data frames to detect the multicast address at the link (MUAx, x=2) of the multicast stream {MUF{T[MUA]}), substituting (B) in each frame at the multicast address (MUAx) at the link a unicast address (UNAy) of a potential receiver terminal (Ty) of the multicast stream to generate a substituted multicast frame (T[UNAy]), transmitting (C) instead of the multicast stream at least one unicast stream, a succession of substituted multicast frames to the terminal at the unicast address at the link. This allows taking advantage of the acknowledgement mechanisms of frames of the transmission of unicast stream for substituted multicast frames. The invention is applicable to transmission of multicast stream in WiFi or CPL network.

Abstract: Coefficients of an adaptive filter representative of an acoustic channel between an emitted acoustic signal and a microphone signal are determined and smoothed in time. An echo is then estimated by filtering the emitted acoustic signal with the smoothed coefficients. Properties of the estimated echo and of the microphone signal are estimated. The echo cancellation filter is controlled as a function of a comparison between the properties of the estimated echo and those of the microphone signal so as to take into account the potential presence of a signal other than an echo signal in the microphone signal.

Abstract: A technique is provided for delivering content to a user. The user sends at least one quality indicator to a first content-delivery device, referred to as a secondary device. The indicator relates to delivery of a portion of the content by a second content-delivery device, referred to as a primary device. When the secondary device detects an event that might affect the delivery of the content by the primary device to the user, on the basis at least of the quality indicators relating to at least a delivery of content by the primary device, it commands the user to transfer from the primary device to the secondary device in order to enable the secondary device to deliver portions of the content that have not been delivered by the primary device.

Abstract: A technique is provided for transmitting a roof structure for constructing a three-dimensional representation of a building, via a communication network. The technique is based on the transmission of an ordered list of at least two roof models, each including at least: one type of roof; one maximum height parameter of the roof. During construction of the three-dimensional representation of a building, the maximum height parameter of a roof of the list determines a base of the roof in accordance with the list, so that the roof structure corresponds to the ordered superimposition of the roods of the list.

Abstract: A method is provided for the transmission of data flows through multiple interfaces. The method includes: comparing a maximum throughput value offered by an interface with a cumulative value resulting from a sum of the throughputs attributed to the flows effectively travelling through the interface; and switching a flow to another interface when the maximum throughput value offered is less than the cumulative value. The method can be used to redirect data flows to an interface other than the current interface when a congestion is detected in the comparison step and to perform optimum dynamic management of the resources of different interfaces as a function of the operating conditions of the interfaces.
