Abstract

A method of sampling, at a central location, data generated from a number of remote data sources. The method comprises:

• • a) causing those data sources with generated data to implement a local response function;
  • b) transmitting information from the central location to the remote data sources relating to the outcome of the local response function;
  • c) causing those data sources with generated data to determine whether the outcome of the local response function satisfies a predetermined relationship with the information transmitted from the central location, and, if it does, to transmit the generated data to the central location.

Claims

1. A method of sampling, at a central location, data generated by a number of remote data sources, the method comprising:

a) causing remote data sources that have locally generated data for transmission to the central station to implement a local response function that generates a local outcome that is independent of the locally generated data;

b) transmitting selection information from the central location to all the remote data sources, the selection information relating to the generated local outcome; and

c) causing remote data sources that have a generated local outcome to determine whether the local outcome satisfies a predetermined relationship with the selection information transmitted from the central location; and

, if it does, transmit the locally generated data to the central location.

2. The method according to claim 1, further comprising:

d) comparing the locally generated data from the data sources at the central location to generate threshold data;

transmitting the threshold data from the central location to all the remote data sources which generated data, for comparison with the locally generated data; and

the remote data sources transmitting their generated data to the central location if it satisfies a predetermined relationship with the threshold data from the central location.

3. The method according to claim 2, wherein the predetermined relationship is satisfied if the locally generated data exceeds the threshold data.

4. The method according to claim 2, further comprising repeating step d) in response to the most recently received transmitted data until no more data is received at the central station.

5. The method according to claim 1, further comprising determining the number of remote data sources which have transmitted data to the central location;

if this number differs from a desired number, transmitting new selection information to all the remote data sources and repeating step c);

the new information chosen to result in the number of remote data sources transmitting data being closer to a desired number.

6. The method according to claim 5, wherein the determining step occurs upon completion of a predetermined time period.

7. The method according to claim 1, wherein the local response function is a random number generating function and the local outcome is a random number.

8. The method according to claim 7, wherein step b) comprises transmitting a range of numbers selected from numbers which could be generated by the random number generating function, and step c) comprises determining whether the local outcome random number falls within the transmitted range.

9. The method according to claim 1, wherein the remote data sources generates data as a result of playing a game, the data comprising a game score.

10. The method according to claim 9, wherein the game is played in response to data transmitted from the central location and locally generated instructions.

11. The method according to claim 9, wherein the game is played in association with a TV broadcast.

12. The method according to claim 1, wherein the central location transmits to the remote data sources via a mass broadcast system such as terrestrial or satellite TV, a cable network or the Internet.

13. The method according to claim 1, wherein the remote data sources transmit to the central location via one of the public switch telephone network, the Internet or a dedicated communication line.

14. The method according to claim 1, further comprising:

d) comparing the locally generated data from the data sources at the central location to generate threshold data;

transmitting the threshold data from the central location to all the remote data sources which generated data, for comparison with the locally generated data;

the remote data sources transmitting their generated data to the central location if it satisfies a predetermined relationship with the threshold data from the central location; and

the central location comparing the transmitted data received at the central location to generate threshold data and transmit the threshold data to all the remote data sources which generated data for comparison with the locally generated data.

15. A method of operating a central station at the central location in the method according to claim 1, wherein the central station transmits selection information from the central location to the remote data sources, the selection information identifying a range of local outcomes generated by respective local response functions.

16. A method of operating a remote data source in the method according to claim 1, wherein the remote data source, in response to having generated data, initiates a local response function to generate a local outcome;

receives selection information transmitted from the central location relating to the generated local outcome;

determines whether the local outcome satisfies a predetermined relationship with the selection information transmitted from the central location; and

, if it does, transmits the generated data to the central location.

17. A central station adapted to carry out a method according to claim 15.

18. A data source adapted to carry out a method according to claim 16.

19. A data generating and sampling system comprising a central station and a number of remote data sources, the system adapted to carry out a method comprising the steps:

a) causing data sources with locally generated data for transmission to the central station to implement a local response function that generates a local outcome that is independent of the locally generated data;

b) transmitting selection information from the central station to all the remote data sources, the selection information relating to the generated local outcome; and

c) causing data sources with a generated local outcome to determine whether the local outcome satisfies a predetermined relationship with the selection information transmitted from the central station, and, if it does, to transmit the locally generated data to the central station.
