Abstract: A method of data synchronisation in a broadcast data receiver (BDR) (4) is provided. The BDR (4) receives data broadcast from a remote location via cable, satellite and/or terrestrial communication means and decodes said data to provide video, audio and/or auxiliary data. The method includes the steps of previewing the data ahead of a start point (106) at which decoding of a data stream (102, 104) is to be initiated in order to identify a time stamp (108) in the data stream, calculating the time period that will be taken to reach the time stamp (108) from the start point (106) and subtracting this time period from the time stamp (108) to provide a pseudo clock reference value for the playback of recorded video and audio data streams (102, 104) from the BDR (4).
