摘要： A sending device receives applications data blocks to be transmitted to a receiving device according to a clock rate defined by transport periods, the applications data blocks being encoded before transmission by application of a first source encoding up to the processing of a change request. The sending device determines a drift between a number of applications data blocks received by the sending device and a number of applications data blocks transmitted after encoding by the sending device. The sending device determines, taking account of the determined drift, a transition applications data block from which a second source encoding is applied in response to the change request. The transmission of the stream is then adapted in such a way that the transmission of the encoded transition data block is aligned with a start of a transport period.

摘要： A method for the transmission of data in a synchronous communications network comprising a plurality of nodes, a super frame being communicated based on a network cycle on the network and comprising a plurality of frames, each frame being associated with one of the nodes. Each frame comprises a payload part itself comprising an own data section and a repeat data section. The plurality of nodes comprises at least one relay node associated with an application generating own data of the relay node having to be transmitted to at least one second node. The relay node performs the following steps: reception of frames coming from the other nodes; reading of a predetermined part of the data from the received frames, enabling repeat data to be obtained; writing said repeat data in the repeat data section of a new frame; writing own data of said relay node in the own data section of the new frame; and transmission of the new frame.

摘要： A method for encoding and decoding a sequence of words, corresponding signal, encoder, decoder, computer programs and storage means. A method for encoding a sequence of source words includes a step of selecting an encoding function to be applied to a source word to be encoded as a function of the content of the word to be encoded and of at least one preceding source word in the sequence so that the concatenation of two consecutive encoded words has no binary element, called an isolated binary element, sandwiched between two binary elements with a value different from that of the isolated binary element. The method further includes a step of encoding the word to be encoded implementing the selected encoding function.

摘要： A protocol data unit switching implements switching means used for the selective interconnection of a transmitter port and at least one receiver port selected from among at least two receiver ports by means of at least one internal bus, each of the protocol data units being constituted by at least one piece of elementary data. The switching implements a synchronization mechanism defining time slots, known as connection cycles, on at least one of said internal buses; a mechanism for the allocation of at least one of said connection cycles to each of the selected receiver ports; and a mechanism for the writing of at least one piece of elementary data in the allocated connection cycle or cycles so as to enable the broadcasting of elementary data to said selected receiver ports.
