Abstract: The present invention relates to a method for retransmission of lost data, a receiving device operating according to the invented method and a retransmission server. In the absence of a unique identifier per data packet or data frame, there is obviously a problem to directly identify a specific data packet, data block or data frame in the stream and retransmission can't take place with current technologies. The object of the present invention is to offer a retransmission method and means for making said retransmission of missing data packets possible in the absence of a unique identifier.
