Abstract:
1. A digital broadcasting method of a broadcasting system for realizing a seamless reception of a digital data stream in a moving vehicle, wherein the method comprises the steps of: providing a data stream of a predetermined initial quality to be transmitted by a transmitter, dividing the data stream into a first digital substream and a second digital substream, wherein the first and second sub streams are complementary to one another in such a way that a recombination of the substreams results in a data stream of the predetermined initial quality, wherein each of the first and second substreams on its own comprises complete information sufficient to reproduce the original content, but a quality reduced content compared to the data stream of the predetermined initial quality to be transmitted, generating a time offset dt between the first and the second substream, transmitting the first and the second substream to a receiver in the moving vehicle in the form of a broadcast by a broadcasting system with the time offset dt such that the first substream is transmitted earlier than the second substream, delaying the first substream in the moving vehicle, and recombining both received substreams into an output stream in the moving vehicle.
