Method and arrangement for locally and wirelessly distributing broadband data
First Claim
1. A method for distributing data stream locally, the method comprising:
- receiving first transmissions from a digital broadcast network by means of a gateway terminal, processing the first transmissions by means of the gateway terminal resulting in a wireless digitally modulated local broadband second transmission, re-transmitting the received first transmissions as the wireless digitally modulated local broadband second transmission, and receiving the wireless digitally modulated broadband second transmission by at least one multimedia terminal.

Abstract
The invention relates to a method and apparatus for transmitting through a single gateway terminal (100) the services required by a plurality of separate multimedia terminals (106). The gateway terminal receives the transmissions (103) coming from several different sources, descrambles and deinterleaves them, if necessary, and re-transmits at an ISM frequency the services required by the multimedia terminals. The service transmitted may be sound, pictures, video, data or system monitoring information. In addition, there is a two-way wireless link from an individual multimedia terminal to the gateway terminal, by means of which link an individual terminal can control the services included by the gateway terminal in its transmission (108).

18. A gateway terminal for receiving and transmitting data stream, the gateway comprising:
-
means for receiving first transmissions from a digital broadcast network, means for processing the first transmissions resulting in a wireless digitally modulated local broadband second transmission, means for re-transmitting the received first transmissions as the wireless digitally modulated local broadband second transmission, wherein the means for re-transmitting the received first transmissions comprises a broadband part for transmitting the second transmission by a broadband digital transmission at a frequency allocated to free use.

-
29. A multimedia terminal for providing user with a data stream of first transmissions, comprising:
-
a receiving antenna for receiving a wireless digitally modulated broadband second transmission resulting from the first transmission, where the receiving antenna for the wireless digitally modulated broadband second transmission in the multimedia terminal is arranged so as to function at a frequency allocated to free use, a receiver block for receiving the second transmission, a demodulator block for demodulating the received transmission, a demultiplexer for separating the received transmission into data of their own, and a descrambling block for descrambling the data, if the data is scrambled.

34. A broadband digital broadcast network arrangement comprising:
-
means for receiving one of generally available and local first transmissions, means for processing the first transmissions by means of the gateway terminal resulting in a wireless digitally modulated local broadband second transmission, means for re-transmitting the received first transmissions as the second transmission, wherein is arranged so as to be transmitted at a frequency allocated to free use means for receiving the second transmission by means of at least one multimedia terminal.
