Abstract

A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys. The content moving device performs the often computationally intense and time consuming transcoding of user content to enable the user to move content between different user devices in a convenient manner.

First claim

What is claimed is:

1. A system for moving content from a first user device to a second user device, comprising:
a hardware processor that is configured to:
detect that the first user device and the second user device are present on a communications network;
identify content on the first user device in a first format as candidate content to be moved to the second user device, wherein the candidate content is in a first format;
transcode the candidate content by decoding the candidate content in the first format as decoded content and encoding the decoded content into a second format compatible with the second user device as transcoded content, wherein the candidate content is transcoded independent of a request for the candidate content by the second user device;
receive, from the second user device, a request for the transcoded content for storage on the second user device; and
in response to receiving the request for the transcoded content, transmit the transcoded content to the second user device over the communications network.

2. The system of claim 1 , wherein the first format has particular characteristics that include a format and a resolution of the first format.

3. The system of claim 1 , wherein the second format has particular characteristics that include a format and a resolution of the second format.

4. The system of claim 1 , wherein the hardware processor is further configured to:
determine a protection scheme associated with the candidate content; and
obtain at least one key for transcoding the candidate content.

5. The system of claim 4 , wherein the at least one key includes a decryption key from the first user device.

6. The system of claim 1 , wherein the hardware processor is further configured to:
determine a protection scheme associated with the candidate content; and
determine whether to transcode the candidate content based on the protection scheme.

7. A method for moving content from a first user device to a second user device, the method comprising:
detecting that the first user device and the second user device are present on a communications network;
identifying content on the first user device in a first format as candidate content to be moved to the second user device, wherein the candidate content is in a first format;
transcoding the candidate content by decoding the candidate content in the first format as decoded content and encoding the decoded content into a second format compatible with the second user device as transcoded content, wherein the candidate content is transcoded independent of a request for the candidate content by the second user device;
receiving, from the second user device, a request for the transcoded content for storage on the second user device; and
in response to receiving the request for the transcoded content, transmitting the transcoded content to the second user device over the communications network.

8. The method of claim 7 , wherein the first format has particular characteristics that include a format and a resolution of the first format.

9. The method of claim 7 , wherein the second format has particular characteristics that include a format and a resolution of the second format.

10. The method of claim 7 , further comprising:
determining a protection scheme associated with the candidate content; and
obtaining at least one key for transcoding the candidate content.

11. The method of claim 10 , wherein the at least one key includes a decryption key from the first user device.

12. The method of claim 7 , further comprising:
determining a protection scheme associated with the candidate content; and
determining whether to transcode the candidate content based on the protection scheme.

13. A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for moving content from a first user device to a second user device, the method comprising:
detecting that the first user device and the second user device are present on a communications network;
identifying content on the first user device in a first format as candidate content to be moved to the second user device, wherein the candidate content is in a first format;
transcoding the candidate content by decoding the candidate content in the first format as decoded content and encoding the decoded content into a second format compatible with the second user device as transcoded content, wherein the candidate content is transcoded independent of a request for the candidate content by the second user device;
receiving, from the second user device, a request for the transcoded content for storage on the second user device; and
in response to receiving the request for the transcoded content, transmitting the transcoded content to the second user device over the communications network.

14. The non-transitory computer-readable medium of claim 13 , wherein the first format has particular characteristics that include a format and a resolution of the first format.

15. The non-transitory computer-readable medium of claim 13 , wherein the second format has particular characteristics that include a format and a resolution of the second format.

16. The non-transitory computer-readable medium of claim 13 , wherein the method further comprises:
determining a protection scheme associated with the candidate content; and
obtaining at least one key for transcoding the candidate content.

17. The non-transitory computer-readable medium of claim 16 , wherein the at least one key includes a decryption key from the first user device.

18. The non-transitory computer-readable medium of claim 13 , wherein the method further comprises:
determining a protection scheme associated with the candidate content; and
determining whether to transcode the candidate content based on the protection scheme.
