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. An apparatus for moving content from a first user device to a second user device, comprising:
a first device interface configured to communicate with the first user device;
a second device interface configured to communicate with the second user device over a home network;
a transcoder;
a storage unit;
a device manager that is configured to:
identify content on the first user device in a first format as candidate content to be moved to the second user device;
receive, via the first device interface, the candidate content in a first format from the first user device;
identify characteristics of the first format of the candidate content to be transcoded;
transcode, via the transcoder, 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;
store the transcoded content in the storage unit;
receive a request from the second user device to provide the transcoded content to the second user device; and
in response to the request for the transcoded content, providing the transcoded content from the storage unit to a memory of the second user device as a file by using the second device interface to transfer the file over the home network.

2. The apparatus of claim 1 , wherein the device manager is further configured to review content at the first user device at predetermined intervals.

3. The apparatus of claim 1 , wherein the device manager is further configured to:
determine that the first user device has started recorded new content; and
in response to determining that the first user device has started recording new content, request the new content from the first user device during recording of the new content at the first user device.

4. The apparatus of claim 1 , wherein the device manager is further configured to receive a notification from the first user device of an event at the first user device, wherein the candidate content is received based on the event.

5. The apparatus of claim 1 , wherein the device manager is further configured to determine a format and resolution of at least one of the first format and the second format.

6. The apparatus of claim 1 , wherein the device manager is further configured to determine if the candidate content is protected.

7. The apparatus of claim 6 , wherein the device manager is further configured to:
determine a protection scheme of the candidate, content; and
provide information related to the protection scheme to the second user device, enabling the second user device to access the content.

8. The apparatus of claim 1 , wherein the device manager is further configured to:
provide a list of available transcoded content to the second user device; and
receive the request to provide the transcoded content to the second user device based on selection from the list of available transcoded content.

9. A method for moving content from a first user device to a second user device using a content moving device, comprising the steps of:
using a device manager to identify content on the first user device in a first format as candidate content to be moved to the second user device;
receiving the candidate content from the first user device via a first device interface controlled by the device manager;
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 received from the first user device and transcoded independent of a request for the candidate content by the second user device;
storing the transcoded content in a storage associated with the content moving device;
receiving a request from the second user device to provide the transcoded content to the second user device;
in response to the request for the transcoded content, providing the transcoded content from the storage to a memory of the second user device as a file over a home network via a second different device interface controlled by the device manager.

10. The method of claim 9 , wherein the step of identifying the content on the first user device comprises reviewing content contained on the first user device at predetermined intervals.

11. The method of claim 9 , wherein the step of identifying the content on the first user device comprises:
determining that the first user device has started recoding new content; and
in response to determining that the first user device has started recording new content, requesting the new content from the first user device during recording of the new content at the first user device.

12. The method of claim 9 , wherein the step of identifying the content on the first user device comprises receiving a notification from the first user device of an event at the first user device, wherein the candidate content is received based on the event.

13. The method of claim 9 , further comprising determining a format and resolution of at least one of the first format and the second format.

14. The method of claim 9 further comprising determining if the candidate content is protected.

15. The method of claim 14 , further comprising:
determining a protection scheme of the candidate content; and
providing information related to the protection scheme to the second user device, enabling the second user device to access the content.

16. The method of claim 9 , further comprising:
providing a list of available transcoded content to the second user device; and
receiving the request to provide the transcoded content to the second user device based on selection from the list of available transcoded content.

17. A non-transitory computer readable medium containing a computer implementable instructions for moving content from a first user device to a second user device using a content moving device, comprising the steps of:
using a device manager to identify content on the first user device in a first format as candidate content to be moved to the second user device;
receiving the candidate content from the first user device via a first device interface controlled by the device manager;
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 received from the first user device and transcoded independent of a request for the candidate content by the second user device;
storing the transcoded content in a storage associated with the content moving device;
receiving a request from the second device to provide the transcoded content to the second user device;
in response to the request for the transcoded content, providing the transcoded content from the storage to the second user device as a file over a home network via a second different device interface controlled by the device manager.

18. The computer readable medium of claim 17 , wherein the step of identifying the content on the first user device comprises reviewing content contained on the first user device at predetermined intervals.

19. The computer readable medium of claim 17 , wherein the step of identifying the content on the first user
