For each stream of a source application, the transmission device: writes to a buffer memory associated with the stream, at the rate of a source applicative clock, pieces of applicative data of the stream coming from the source application, transmits, via the network, pieces of applicative data of the stream at the rate of the network clock. For at least one stream of the source application, the transmission device performs the following steps upon detection of a clock adjustment event: determining a piece of time offset information between a starting instant of a current network cycle and an instant of writing one of the pieces of applicative data of the stream, called a reference piece of data, to the buffer memory associated with the stream; determining a piece of information on position of the reference piece of data from among the pieces of applicative data of this stream to be transmitted via the network during a determined network cycle; transmission on the communications network of the information on time offset and position during the same network cycle as the one in which the reference piece of data is transmitted.Methods for synchronizing applicative clock signals in a synchronous communications network, corresponding emitter and receiver devices, computer-readable storage means.

摘要： A coding method for a sequence of elements that can be equal to at least two distinct values, the elements forming at least one input symbol. The coding method comprises a stretching step of stretching at least one of the input symbols, to form a stretched symbol, such that the stretched symbol does not have any successive transitions. The coding method further comprises a cancelling step of canceling the disparity of the stretched symbol to form a coded symbol, such that the coded symbol comprises approximately the same number of elements of each value.
