Abstract:
1. Method for aligning first audio data with related second audio or video data before multiplexing, wherein input time stamps are generated which become linked with audio or video data to be encoded and which are used to control the delay of the encoding process, and wherein output time stamps are derived from the input time stamps by using a data delay constant and are assigned to the encoded data for indicating the output time, and wherein the encoded data with assigned output time stamps are buffered before output, characterised in that the output delay of the first audio data is adapted to the output time of the related second audio or video data; for a change of the output delay said data delay constant is change-already assigned output time stamps remain unchanged; and for data for which output time stamps are not already assigned, the output time stamps are calculated using the new data delay constant.
