摘要： A method is provided for configuring an overall encoding scheme comprising a first encoding for generating first encoded packets from source packets and a second encoding for generating second encoded packets by combination of first encoded packets according to a combination scheme applied by predetermined nodes of the network. The method obtains a number N of defective paths among paths used to transmit the first and second encoded packets to at least one destination node, a path being defective if an associated quality of transmission is below a predetermined threshold. A combination scheme is selected from among at least two possible predetermined combination schemes for which a number of encoded second packets is greater than or equal to N.

摘要： A method is proposed for decoding a plurality of data packets received through a meshed communications network for the retrieval of source packets transmitted by one or more source nodes, the meshed communications network comprising relay nodes generating combined packets, each combined packet consisting of a linear combination of source packets. During the decoding by a destination node, this method consists in performing two decoding operations of which the first is a decoding by group of packets and the second is a decoding that takes account of pieces of likelihood information resulting from the first decoding. The fact of first of all carrying out a decoding with groups of packets makes it possible to exploit the repetitions (or redundancies) of packets in a meshed network to optimize the bit error rate during the decoding of source data transmitted on the communications network.

摘要： A method for managing allocation of paths for transmission, in packets of symbols, of at least a first data content, each content being transmitted from a source node up to a destination node in a meshed communications network comprising a plurality of nodes, each destination node receiving a plurality of copies of a same packet of symbols of the content transmitted to said destination node by a source node, each copy being received by the destination node via a distinct transmission path directly from the source node or via at least one relay node of the meshed communications network, the packets being encoded with an error correction code enabling decoding by erasure of packets symbols. Such a method comprises the following steps: selecting a set of transmission paths from the source node up to the destination node for the transmission of copies of at least one packet of the first content, for which an estimated first number of erasures of symbols of the at least one packet is smaller than a determined threshold, the first number of erasures being estimated from a piece of information on quality of transmission that is determined and associated with each of the selected transmission paths, the threshold being determined as a function of an erasure correction capability of the error correction code; allocating the selected transmission paths to the transmission of the first content from said source node up to said destination node.

摘要： The invention relates to a method of reconstructing pixel values of a video frame for concealing corrupted pixel values. The method comprising receiving, by a receiving unit, of a signal from a communication channel and delivering by the receiving unit of video packets comprising pixel values possibly corrupted with errors; associating confidence levels with pixel values comprised in the video packets as delivered by the receiving unit; and reconstructing pixel values usable for display from the received pixel values, wherein a reconstructed value for a given pixel is obtained from the received values of a set of pixels, including the given pixel, weighted by their associated confidence levels.The invention allows for better reconstruction of corrupted pixel values and reduces the perceived distortion when displaying the video frame.

摘要： A method is proposed for determining an erasures vector associated with a data block to be decoded built out of received copies, and using levels of reliability of transmission associated with symbols contained in different copies of a same block of received pieces of data.Such a method advantageously makes reduces the error rate at output of a decoder by minimizing the operations to be performed to determine the erasures vector, marking the erasures and preventing the generation of an excessively large number of erasures (even when the transmission of certain received copies is unreliable) to have a number of erasures that does not exceed the correction capacity of the decoder.
