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.
