Abstract
A method and a transcoder for transcoding data communicated between a sender (100) and a receiver (102). Data units (202, 208) comprising information in a first format (F, IF) are received and coded into new data units (208, 210) in a second format (IF, F'), based on a current coding state (302, 502, 706) extracted from a previous coding of data. A new current coding state is extracted each time a data unit (202, 500, 700) is coded. If a received data unit is in an erroneous sequence order, the current coding state is saved and a new pseudo coding state (DS2', ES2', CS2') is eytracted for codng a next received data unit. Eventually received missing data (F2, S4) is coded into the second format (IF, F') based on the saved coding sate, and may then be used as valid data. In this way, delays are minimised and jitter buffers are not necessary, while still maintaining a high quality.
