Abstract

An information delivery system comprises equipment located at a first or storage location (10) and additional equipment located at a second or utilization location (11). The locations are interconnected for transmission of information therebetween by a communication medium (12). The system includes elements and methods for increasing the effective rate of transfer of information across information medium 12. These elements and methods include data compression including iterative data compression. The elements and methods further include the synchronised superposition of channels forming communication medium (12). Communication medium (12) can include a cellular mobile telephone network to permit transmission of information between mobile stations (311, 312) and to cellular receivers (217).

Claims

1. An information transmission system for transmission of relatively wide-bandwidth information from a first location to a second location in a cellular telephone network, said system comprising:

a receiver/transmitter base station at said first location;

a cellular receiver at said second location;

a communication channel in the cellular telephone network adapted to transmit the information from the first location to the second location upon a request over the communication channel initiated by a user of the cellular telephone network; and

wherein the communication channel is implemented as a wide-bandwidth data path by the establishment of a plurality of individual channels of predetermined bandwidth acting together to connect the base station to the cellular receiver, whereby the data path has a bandwidth greater than the predetermined bandwidth of any one of said individual channels.

2. The system of claim 1 wherein the relatively wide-bandwidth information includes video signals.

3. The system of claim 2 wherein the base station includes the first video signal storage means and video signal compression means.

4. The system of claim 3 wherein the video signals are passed from said first video signal storage means to said video signal compression means for compression of said video signals prior to said storage means.

5. The system of claim 4 wherein the video signals are iteratively compressed by repeated, adaptive and selective invocation of said compression means.

6. The system of claim 2 wherein the cellular receiver includes video signal decompression means and video signal storage means.

7. The sytem of claim 6 wherein said decompression means decompresses the video signals prior to storage of said video signals in said storage means.

8. The system of claim 7 wherein the video signals are iteratively decompressed through repeated passage between said decompression means and said storage means.

9. The system of claim 2 wherein said second location includes means for displaying the video signals.

10. The system of claim 9 wherein said display means comprises a television receiver.

11. The system of claim 9 wherein said video display means comprises a video phone terminal.

12. The system if claim 9 wherein said video display means comprises a hand-held mobile phone incorporating a video data display.

13. The system of claim 2 wherein said video signals are transmitted over said communication channel in digital form.

14. The system of claim 2 wherein said first location includes a storage bank in which said video signals are stored.

15. The system of claim 2 wherein said second location includes means for storing the video signals.

16. The system of claim 2 wherein said video signals are transmitted over said communication channel in real time.

17. The system of claim 1 wherein portions of the bandwidth of the relatively wide-bandwidth information are distributed across said plurality of individual channels.

18. The system of claim 1 wherein the predetermined bandwidth of each individual channel includes a control layer and a signal layer, wherein the establishment of said plurality of individual channels is orchestrated through the signal layers of the respective individual channels.

19. An information transmission system for transmission of relatively wide-bandwidth information from a first location to a second location in a cellular telephone network, said system comprising:

a first mobile station including a transmitter portion, at said first location;

a second mobile station including a receiver portion, at said second location;

a communication channel in the cellular telephone network adapted to transmit the information from the first location to the second location upon a request over the communication channel initiated by a user of the cellular telephone network; and

wherein the communication channel is implemented as a wide-bandwidth data path by the establishment of a plurality of individual channels of predetermined bandwidth acting together to connect the first mobile station to the second mobile station, whereby the data path has a bandwidth greater than the predetermined bandwidth of any one of said individual channels.

20. The system of claim 19 wherein the relatively wide-bandwidth information includes video signals.

21. The system of claim 20 wherein said second location includes means for displaying the video signals.

22. The system of claim 21 wherein said video display means comprises a hand-held mobile phone incorporating a video data display.

23. The system of claim 22 wherein said mobile phone is comprised of a relatively high electromagnetic radiation emitting portion and a relatively low electromagnetic radiation emitting portion, said low radiation emitting portion being adapted for placement at or near the head of a user and in communication with said high electromagnetic radiation emitting portion, said high electromagnetic radiation emitting portion being adapted for location around the waist of the user and further adapted for communication with the cellular telephone network.

24. The system of claim 20 wherein said video signals are transmitted over said communication channel in digital form.

25. The system of claim 20 wherein said first location includes a storage bank in which said video signals are stored.

26. The system of claim 20 wherein said second location includes means for storing the video signals.

27. The system of claim 20 wherein said video signals are transmitted over said communication channel in real time.

28. The system of claim 19 wherein portions of the bandwidth of the relatively wide-bandwidth information are distributed across said plurality of individual channels.

29. The system of claim 19 wherein the predetermined bandwidth of each individual channel includes a control layer and a signal layer, wherein the establishment of said plurality of individual channels is orchestrated through the signal layers of the respective individual channels.

30. The system of claim 19 wherein the communication channel connecting the first mobile station to the second mobile station is established via local transmitter/receiver base stations which are in direct communication respectively with the first mobile station and the second mobile station.
