Abstract

A system and method are disclosed for providing streaming data information to a receiver. The system accesses one or more information service providers for providing respective information signals, input buffers for storing portions of the streaming information, a digital broadcast transmitter for broadcasting the contents of the input buffers as transmission bursts, a digital broadcast receiver for receiving the transmission bursts for storage in a receiver input buffer, and an application processor for converting the transmission bursts to an information transmission stream. The digital broadcast receiver is synchronized with the transmitter broadcasts to allow for powering down between selected transmission bursts.

Claims

1. An apparatus comprising:

a processor configured to;

receive streaming information from a service provider; and

transmit, from the apparatus, said streaming information in a digital video broadcast transmission burst to a remote mobile terminal at a higher bit rate than the rate at which said streaming information is received from the service provider, wherein the digital video broadcast transmission burst is transmitted as a time sliced signal and wherein the transmission is synchronized with a powering-up of the remote mobile terminal.

2. The apparatus of claim 1, wherein at least one service is provided by the information service provider via at least one information stream.

3. The apparatus of claim 1, wherein the transmission of the digital video broadcast transmission burst is synchronized with the powering-up of a digital video broadcast receiver of the remote mobile terminal based on a pre-determined powered-up time.

4. The apparatus of claim 3, wherein said pre-determined powered-up time occurs an incremental period of time prior to the transmission of said digital video broadcast transmission burst.

5. The apparatus of claim 3, wherein said pre-determined powered-up time occurs a specified period of time subsequent to said pre-determined powered-down time.

6. The apparatus of claim 1, wherein the remote mobile terminal comprises an application processor configured to convert said digital video broadcast transmission burst into an information data stream.

7. The apparatus of claim 1, further comprising a multi-protocol encapsulator for encapsulating at least a portion of said streaming information.

8. The apparatus of claim 7, wherein the encapsulation is removable using an Internet protocol (IP) filter.

9. The apparatus of claim 1 further comprising:

a service input buffer for storing at least an interval of second streaming information provided by a second information service provider, wherein the apparatus broadcasts the contents of said second service input buffer as a second digital video broadcast transmission burst.

10. The apparatus of claim 9, further comprising a multiplexer for multiplexing said digital video broadcast transmission burst and said second transmission burst such that said apparatus broadcasts said digital video broadcast transmission burst and said second transmission burst as a time-division multiplexed signal.

11. The apparatus of claim 9, further comprising a network operator input buffer.

12. A method comprising:

receiving streaming information from a service provider; and

transmitting, from a digital video broadcast transmitter, said streaming information in a digital video broadcast transmission burst to a remote mobile terminal at a higher bit rate than the rate at which said streaming information is received from the service provider, wherein the digital video broadcast transmission burst is transmitted as a time sliced signal and wherein the transmission is synchronized with a powering-up of the remote mobile terminal.

13. The method of claim 12, further comprising encapsulating the streaming information.

14. The method of claim 12 further comprising:

receiving second streaming information supplied by a second service provider; and

encapsulating said second streaming information.

15. The method of claim 14, further comprising multiplexing the digital video broadcast transmission burst and the second streaming information such that the digital video broadcast transmission burst and the second streaming information are transmitted as a time division multiplexed signal.

16. The method of claim 13, wherein the digital video broadcast transmission burst is transmitted a predefined period of time prior to the powering-up of the remote mobile terminal.

17. The method of claim 12, wherein a size of the digital video broadcast transmission burst is defined independently of a receiver bandwidth allocation.

18. The method of claim 12, wherein at least one service is provided by the information service provider via at least one information stream.

19. The method of claim 12, wherein the transmission of the digital video broadcast transmission burst is synchronized with the powering-up of a digital video broadcast receiver of the remote mobile terminal based on a pre-determined powered-up time.

20. The method as in claim 12, wherein said pre-determined powered-up time occurs an incremental period of time prior to the transmission of said digital video broadcast transmission burst.
