Abstract

A mobile live information system consists of a digital video camera mounted in a vehicle. The signal is fed to a computer 10 which divides the datastream to be transmitted into a plurality of packets which can be simultaneously transmitted using a number of wireless modems connected in parallel. In a receiving portion, the video image and other imports are reconstructed and can be displayed live as an Internet or other broadcast. The system has other applications in electronic newsgathering and security.

Claims

1. A live information system comprises a remote portion comprising one or more sources of information, means for encoding the information into a compressed digital form, means for processing the compressed data into packets, and a plurality of digital wireless modems for simultaneously transmitting respective data packets to provide an increased bandwidth channel, and a receiving portion for reassembling the received data packets.

2. A live information system as claimed in claim 1, further comprising a back channel for transmitting from the receiving portion to the remote portion.

3. A live information system as claimed in claim 1, wherein the sources of information are selected from video data, audio data, telemetry data relating to a vehicle in which the mobile portion is mounted.

4. A live information system as claimed in claim 1, wherein the remote portion further comprises means for storing digital information data of higher resolution than that which is processed for live transmission.

5. A live information system as claimed in claim 4, further comprising means for transmitting the stored digital information data of higher resolution than that which is processed for live transmission when bandwidth is available.

6. A live information system according to claim 1 in which the remote portion is mobile.

7. A live information system including a remote portion comprising a video camera, means for compressing, encoding and processing the data into a compatible digital data stream and at least one digital wireless modem, and a receiving portion for receiving and decoding the data stream.

8. An information system comprising a remote portion comprising of one or more sources of information, means for encoding the information into a digital form, means for processing the compressed data into packets, and a plurality of digital wireless modems for simultaneously transmitting respective data packets to provide an increased bandwidth channel, and a receiving portion for reassembling the received data packets.

9. A simulator comprising a user feedback station equipped with at least one of a video image generator and a motion generator, and a remote unit, the user feedback station and the remote unit being linked via a means for encoding information produced at the remote unit into a compressed digital form, means for processing the compressed data into packets, and a plurality of digital wireless modems for simultaneously transmitting respective data packets to provide an increased bandwidth channel, and a receiving portion for reassembling the received data packets and feeding them to the user feedback station to replicate conditions at the remote unit for the user.

10. A simulator comprising a user feedback station equipped with at least one of a video image generator and a motion generator and a wireless data link to a mobile vehicle taking part in a sporting event, the user feedback station being equipped with at least one of an image and a motion generator to reproduce for a user conditions at the mobile vehicle.

11. A simulator according to claim 10 in which the user feedback station includes game software whose rules correspond to those of the sporting event thereby to allow the user to compete against the mobile vehicle.

12. A simulator system comprising a user feedback station equipped with at least one of a video image generator and a motion generator and a data link to a remote system, the user feedback station being equipped with at least one of an image and a motion generator to reproduce for a user to be relayed live or recorded conditions at the mobile vehicle.

13. A unit for connection to a computer as a modem, including a processor and a plurality of internal or external wireless modems, arranged such that it provides functionality to the computer equivalent to a single modem, but allows a higher bandwidth connection to another such device or equivalent device than could otherwise be obtained by spreading data across the plurality of modems.

14. A method of assigning limited bandwidth to several units capable of low and high bandwidth transmission, such that switching of low and high bandwidth transmissions from each unit can be selected in order to maximise utilisation of the available bandwidth.
