Verfahren zum Betrieb eines Datenuebertragungsnetzes

DE 102006011628 A1 UPAB: 20070927 NOVELTY - The method involves transmitting a data stream with a small data rate and a bandwidth for a program from a provider using a broadcast method. Another data stream with a high data rate and/or bandwidth is transmitted to the program using a multi-cast method based on a request by a user, where the latter data stream contains data requested by the user. The former data stream is transmitted in a reduced form upon reaching a full extent, while the former data stream is selected by the user. USE - Used for transmitting program data e.g. computer game, music data, information content, service data, video data such as film, and television program, from a provider to a communication network such as packet-switching network e.g. Internet and public Ethernet , to provide an Internet accessing service, voiceover Internet protocol (VoIP) service and IP television service, over a worldwide interoperability for microwave access (Wi-max) . ADVANTAGE - The method facilitates switching between the data streams in a fast, comfortable and convenient manner, without overburdening the network with respect to the bandwidth of the data to be transmitted, achieves the resource saving, and reduces cost for transmission of the data stream
