Patent ID: 8804771

Claim:
A method for managing transmission of a data stream from a sending device, the sending device receiving 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 at the sending device for changing said encoding to a second source encoding prior to transmission, in which method the sending device: determines a drift as a difference between a number of applications data blocks received by the sending device and a number of encoded applications data blocks transmitted prior to the change request by the same sending device; determines, taking account of the determined drift, a transition applications data block from which the second source encoding is applied to said received applications data blocks prior to transmission from the sending device, in response to the change request; and adapts the transmission of the stream by adding padding data, such that the transmission of the encoded transition data block is aligned with a start of a transport period.
