Abstract

A system for transmission of data signals over a wireless network having an encoding module for encoding video data into a plurality of buffers for transmission. The system also has a feedback module for processing feedback from one or more sources, wherein the encoding module dynamically alters the amount of data that is encoded into the one or more video buffers based at least in part on the feedback received. A method for transmission of data signals over a wireless network including encoding video data into a plurality of buffers, transmitting some of the data, processing feedback from one or mores sources, wherein the feedback relates to delivery parameters and dynamically altering the amount of data passed into the buffers based at least in part on the data received.

Claims

1. A system for transmission of data signals from a mobile device to a network comprising:

an encoding module for encoding video data into a plurality of video buffers for transmission; and

a transport controller module for processing feedback from one or more sources, wherein the encoding module dynamically alters the amount of data that is encoded into the plurality of video buffers based at least in part on the feedback received;

wherein the feedback from one or more sources comprises a network latency determined by synchronizing a clock of a transmitter with a clock of a receiver and measuring a delay associated with delivering the encoded video data from the transmitter to the receiver.

2. The system of claim 1 wherein the feedback from the one or more sources includes received signal strength.

3. The system of claim 1 wherein the feedback from the one or more sources includes frequency of lost packets.

4. The system of claim 1 wherein the dynamic altering of the amount of data includes at least one of the following:

scaling the image data, changing the encoding bit rate or changing the frame rate.

5. The system of claim 1 wherein the encoding module is connected to a video buffer where one or more video packets are held for delivery over one or more wireless networks.

6. The system of claim 5 wherein the transport controller module is connected to one or more sources adapted to be a wireless link for delivery of the one or more video packets and to provide feedback in relation to wireless network conditions and delivery results for the one or more video packets.

7. The system of claim 1 wherein the transport controller module delivers the encoded video data to one or more radio frequency (RF) modules based on the feedback received.

8. A method for transmission of data signals from a wireless device to a network comprising:

encoding video data into a plurality of buffers;

transmitting a portion of the data;

processing feedback from one or more sources, wherein the feedback relates to delivery parameters; and

dynamically altering the amount of data passed into the buffers based at least in part on the feedback received;

wherein the feedback from one or more sources comprises a network latency determined by synchronizing a clock of a transmitter with a clock of a receiver and measuring a delay associated with delivering the encoded video data from the transmitter to the receiver.

9. The method of claim 8 wherein processing feedback comprises determining network latency of various radio frequency (RF) module connections.

10. The method of claim 9 wherein if the latency of an RF module is above a threshold value, the data is rerouted to a better performing RF module.

11. The method of claim 8 wherein processing feedback comprises determining received signal strength indicator.

12. The method of claim 8 wherein processing feedback comprises determining packet delivery failure.

13. The method of claim 8 wherein processing feedback comprises determining delivered bit rate compared to transmitted bit rate.

14. The method of claim 8 wherein processing feedback comprises determining the pending data in queue awaiting transmission.

15. The method of claim 8 wherein processing feedback comprises determining network latency.

16. The method of claim 8 wherein the dynamic altering of the amount of data comprises at least one of the following:

scaling the image data, changing the encoding bit rate or changing the frame rate.

17. A non-transitory computer readable medium configured to execute a method for transmission of data signals from a wireless device to a network, the method comprising:

encoding video data into a plurality of buffers;

transmitting a portion of the data;

processing feedback from one or more sources, wherein the feedback relates to delivery parameters; and

dynamically altering the amount of data passed into the buffers based at least in part on the feedback received;

wherein the feedback from one or more sources comprises a network latency determined by synchronizing a clock of a transmitter with a clock of a receiver and measuring a delay associated with delivering the encoded video data from the transmitter to the receiver.
