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： It is proposed a method for synchronizing a transmission of applications data frames provided to a sender device, the transmission being done between said sender device and at least one receiver device via a synchronous communications network implementing a clock that defines a network cycle.Upon detection of an event representing a start of an applications data frame, the sender device performs steps of: determining a piece of information on time offset between the instant of detection of the event and a reference instant of a network cycle as well as a piece of information on position of said first network cycle in a sequence of network cycles; transmitting the piece of information on time offset and the piece of information on position, during a first network cycle; processing for transmission, in a bounded lapse of time, a set of applications data starting from the start of the frame; transmitting, the processed applications data starting from a second network cycle subsequent to said first network cycle.
