Abstract: In a method for transmitting a data stream, especially a reducible data stream, from a producer to a plurality of viewers, wherein producer and viewers are subscribers in a network having point-to-point connections, the producer transmits the data stream over a point-to-point network connection to at least one viewer, at least one viewer receives the data stream over a point-to-point network connection and promptly transmits it in identical or reduced form to at least one additional viewer, and every viewer is promptly supplied with the data stream in identical or reduced form by either the producer or another viewer over a point-to-point network connection.
