Abstract

An electronic device for media file caching for conserving resources is described. The electronic device includes a processor and instructions stored in memory. The electronic device monitors requests for a media file, stores media file information and determines whether the media file should be stored locally based on the media file information. If it is determined that the media file should be stored, the electronic device saves the media file and presents the media file.

Claims

1. An electronic device for media file caching for conserving resources, comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable to;

monitor requests for a media file;

store media file information, wherein the media file information comprises a count threshold of requests originating at the electronic device and one or more of an amount of processing power and an amount of power resources needed to decode the media file for presentation on the electronic device;

determine whether the media file should be stored locally based on the media file information, and if it is determined that the media file should be stored, then;

save the media file in a native format; and

present the media file.

2. The electronic device of claim 1, wherein determining whether the media file should be stored locally is based on a number of requests.

3. The electronic device of claim 1, wherein determining whether the media file should be stored locally is based on an original format decoding cost.

4. The electronic device of claim 1, wherein determining whether the media file should be stored locally is based on a native format decoding cost.

5. The electronic device of claim 1, wherein determining whether the media file should be stored locally is based on a transcoding cost.

6. The electronic device of claim 1, wherein the instructions are further executable to:

detect subsequent requests for the media file; and

present the media file in the native format when subsequent requests for the media file are detected.

7. The electronic device of claim 1, wherein the media file is saved in local memory on the electronic device.

8. The electronic device of claim 1, wherein the media file is saved in local memory on another electronic device in a local network.

9. The electronic device of claim 1, wherein saving the media file comprises transcoding the media file from an original format into the native format.

10. The electronic device of claim 1, wherein the instructions are further executable to determine the count threshold.

11. The electronic device of claim 1, wherein the media file should be stored if a request count is greater than or equal to the count threshold.

12. The electronic device of claim 1, wherein the media file should be stored if a request rate is greater than or equal to a rate threshold.

13. The electronic device of claim 1, wherein the media file comprises one or more media streams.

14. The electronic device of claim 1, wherein the electronic device is a wireless communication device.

15. The electronic device of claim 1, wherein the media file is presented in the native format.

16. The electronic device of claim 1, wherein the media file is presented in an original format.

17. A method for media file caching for conserving resources on an electronic device, comprising:

monitoring requests for a media file;

storing, by an electronic device, media file information, wherein the media file information comprises a count threshold of requests originating at the electronic device and one or more of an amount of processing power and an amount of power resources needed to decode the media file for presentation on the electronic device;

determining, on the electronic device, whether the media file should be stored locally based on the media file information, and if it is determined that the media file should be stored, then;

saving the media file in a native format by the electronic device; and

presenting the media file on the electronic device.

18. The method of claim 17, wherein determining whether the media file should be stored locally is based on a number of requests.

19. The method of claim 17, wherein determining whether the media file should be stored locally is based on an original format decoding cost.

20. The method of claim 17, wherein determining whether the media file should be stored locally is based on a native format decoding cost.

21. The method of claim 17, wherein determining whether the media file should be stored locally is based on a transcoding cost.

22. The method of claim 17, further comprising:

detecting subsequent requests for the media file; and

presenting the media file in the native format when subsequent requests for the media file are detected.

23. The method of claim 17, wherein the media file is saved in local memory on the electronic device.
