Abstract

A portable media enhancement device for use with a mobile device for processing one or more media files is provided. The mobile device is located separately from the portable media enhancement device. The portable media enhancement device comprises a docking connection input used to communicate with the mobile device and at least one control module. The control module is configured to establish a connection with the mobile device via the docking connection input and to receive one or more media files from the mobile device. The control module is further configured to decode the one or more media files and post process the one or more media files. The control module is further configured to transmit the decoded and processed media files to the mobile device.

Claims

1. A portable media enhancement device for use with a mobile device, where the mobile device is located separately from the portable media enhancement device, the portable media enhancement device comprising:

a docking connection input;

at least one processor and a memory, wherein the memory contains instructions for causing the processor to;

establish a connection with a mobile device via the docking connection input;

receive one or more media files from the mobile device, the one or more media files are not compatible for playback on the mobile device;

decode the one or more media files to generate one or more decoded files;

process the one or more decoded files to generate one or more post-processed media files; and

transmit the one or more post-processed media files to the mobile device such that the mobile device plays back the one or more processed media files; and

a microphone to sense ambient sound for use by the processor when generating the post-processed media files.

2. The portable media enhancement device of claim 1, further comprising at least one of a display output and an audio output.

3. The portable media enhancement device of claim 2, wherein the at least one processor is further configured to transmit the post-processed media files to an alternate device for output based on the at least one of the display output and the audio output.

4. The portable media enhancement device of claim 2, wherein the display output is at least one of High-Definition Multimedia Interface connector, optical connector, DisplayPort connector, Digital connector, and a coaxial connector.

5. The portable media enhancement device of claim 2, wherein the audio output is at least one of coaxial, optical and digital interconnect format.

6. The portable media enhancement device of claim 1, wherein the process of the one or more media files is at least one of stereo widening, acoustic equalization, automatic loudness and volume control, low bit rate enhancement, and audio upmixing, which use the ambient sound from the microphone.

7. The portable media enhancement device of claim 1, wherein the process of the one or more media files is at least one of denoising, deinterlacing, upscaling, and stabilization.

8. The portable media enhancement device of claim 1, wherein the docking connection input includes at least one of wireless communication and wired communication, the wireless is at least one of WiFi, Near Field Communication, BLUETOOTH, and the wired communication is at least one of Serial Peripheral Interface Bus, Inter-Integrated circuit, and Universal Asynchronous Receiver/Transmitter.

21. The portable media enhancement device of claim 1, wherein the at least one processor is configured to use the ambient sound sensed by the microphone to develop a virtual room simulation and to process audio using the virtual room simulation.

22. The portable media enhancement device of claim 1, wherein the at least one processor is configured to receive processing control signals from the mobile device.

23. The portable media enhancement device of claim 1, wherein the at least one processor is upload a control application to the mobile device and receive control instructions for processing the media file from the control application on the mobile device.

9. A non-transitory computer medium that is encoded with instructions, when executed by a device, cause the device to:

establish a connection with a portable media enhancement device and a mobile device via a docking connection port;

receive at the portable media enhancement device, from the mobile device one or more media files that are non-compatible with the mobile device;

sense ambient sound with a microphone;

process the one or more media files and the sensed ambient sound to generate one or more processed media files to be compatible with the mobile device; and

output the one or more processed media files to the mobile device.

10. The computer media of claim 9, further comprising instructions for receiving an editing command for the one or more media files, to edit the one or more processed media files;

and outputting the edited media files.

11. The computer media of claim 10, wherein the editing command includes at least one of image cropping, resizing, and brightness changes.

12. The computer media of claim 11, wherein the editing command is received at a user interface on the mobile device.

13. The computer media of claim 9, further comprising instructions for enabling wireless communication or wired communication with the portable media enhancement device via the docking connection port.

14. The computer media of claim 9, wherein the instructions for processing of the one or more media files further includes instructions for performing at least one of denoising, deinterlacing, upscaling, stabilization, stereo widening, acoustic equalization, and audio upmixing of the one or more media files.

15. A mobile device comprising:

a transceiver in communication with an portable media enhancement device; and

a processor positioned in the mobile device in communication with the transceiver, the processor being configured to;

establish a connection with the portable media enhancement device via the transceiver;

transmit one or more media files that are non-compatible with the mobile device to the portable media enhancement device; and

receive compatible media files, which have been audio processed to account for ambient sound sensed by the portable media enhancement device, from the portable media enhancement device for output at the mobile device.

16. The mobile device of claim 15, wherein the processor is further configured to output the media files to at least one of a display output and an audio output.

17. The mobile device of claim 16, wherein the processor is further configured to transmit the media files to an alternate device for output based on the at least one of the display output and the audio output.

18. The mobile device of claim 16, wherein the display output is at least one of High-Definition Multimedia Interface connector, optical connector, DisplayPort connector, Digital connector, and a coaxial connector.

19. The mobile device of claim 16, wherein the audio output is at least one of coaxial, optical and digital interconnect format.

20. The mobile device of claim 15, wherein the transceiver is at least one of wireless communication and wired communication.

24. A portable media enhancement device for use with a mobile device, where the mobile device is located separately from the portable media enhancement device, the portable media enhancement device comprising:
