Abstract
A method for signaling a time and/or clock through a header station generating a transport datastream from video and/or audio data to at least one receiver of the transport datastream calculates the time information (PCRN+1; RTPN+1; TN+1) integrated in a transport data packet of the transport datastream iteratively from the time information (PCRN; RTPN; T1) of the transport data packet last transmitted in the transport datastream with integrated time information, from a transmission time of data bits transmitted since the last transmitted transport data packet with integrated time information in the transport datastream and from a clock (fPCR; fSys). The time information (PCRN+1, PCRN; RTPN+1, RTPN; TN+1, T1) serves in each case for the signaling of times or a clock, and, in each case, contains a pulse number counted up to the transmission time of the respective transport data packet of the clock (fPCR; fSys).
