    摘要: A method of transmitting a video frame over a plurality of communication channels involves selecting a number of communication channels available between the transmitting and the receiving devices; partitioning spatially correlated pixels of the video frame into a number of different partitions equal to the number of selected communication channels; and transmitting the different partitions, where each partition is transmitted on a distinct communication channel among the selected communication channels.Such a method is suitable for use in a communication system, especially a wireless communication system, in which data of a channel can be lost or corrupted. The method can maximize diversity in the transport of the video frame pixels and improve robustness.

    摘要: A method is proposed for synchronizing a data stream transmitted on a communications network, the data stream being transmitted from an emitter device to a receiver device in the form of data packets of predefined size, a data packet being filled up with a padding synchronization symbol if an amount of applications data to be transmitted in the data packet is below the predefined size of the data packet. The receiver device performs the following steps: obtaining an indication of a recurrence of filling of the data packets with padding synchronization symbols; upon detection, at a position in the data stream, of a data loss symbol representative of a lost data in a given data packet, predicting whether the lost data corresponds to an applications data or a padding synchronization symbol, as a function of a position of the given data packets in the recurrence; and marking that the data stream contains, at the data loss symbol position, an erroneous applications data, if the result of the predicting step is that the lost data corresponds to an applications data; or replacing the data loss symbol by a padding synchronization symbol, if the result of the predicting step is that the lost data corresponds to a padding synchronization symbol.
