Patent ID: 6999473

Claim:
A data transmission method with improved transmission quality, the method which comprises: transmitting a first data stream at a predetermined data rate from a transmitter via a network node in a data packet oriented communication network to a receiver; forwarding data of the first data stream from the network node together with data from at least one further data stream and, if a transmission capacity that is jointly available for the data streams is exceeded, rejecting data packets in the data streams to be transmitted by the network node; adding redundant data to the first data stream with the transmitter and thereby increasing a redundancy and increasing a data rate of the first data stream arriving at the network node in relation to a data rate of the at least one further data stream, and to thereby cause a greater proportion of the jointly available transmission capacity to be taken up by the data of the first data stream; determining, in the receiver, from the first data stream a measure for a transmission quality thereof; transmitting with the receiver an acknowledgement to the transmitter depending on the determined measure for the transmission quality; and adding redundant data to the first data stream with the transmitter depending on the acknowledgement.
