Abstract

Systems and methods of sharing media content with digital rights management are disclosed that include receiving a media file having media content with a user device, the media content having a first portion and a second portion, when a selection of the provided media content is received by the user device, presenting the first portion of the media content with the user device when the first portion is unencrypted or by decrypting the first portion of the media content with a publically available key with the user device, and presenting the second portion of the media content with the user device when the presentation of the first portion of the media content is complete and when a digital rights management (DRM) key is purchased to decrypt the second portion of the media content.

Claims

1. A method comprising:

receiving a media file having media content with a user device, the media content having a first portion and a second portion;

when a selection of the provided media content is received by the user device, presenting the first portion of the media content with the user device when the first portion is unencrypted or by decrypting the first portion of the media content with a publically available key with the user device; and

presenting the second portion of the media content with the user device when the presentation of the first portion of the media content is complete and when a digital rights management (DRM) key is purchased to decrypt the second portion of the media content.

2. The method of claim 1, wherein the receiving the media file with the user device comprises:

receiving, with the user device, a single file having a first file block including the first portion of the media content and a second file block including the second portion of the media content.

3. The method of claim 2, further comprising:

receiving, with the user device, the DRM key to decrypt the second file when the DRM key is purchased.

4. The method of claim 1, wherein the receiving the media file with the user device comprises:

receiving a first file including the first portion of the media content, and receiving a second file including a second portion of the media content.

5. The method of claim 4, wherein the second file is received when a purchasing selection of the media file has been received with the user device.

6. The method of claim 4, further comprising:

receiving, with the user device, the DRM key to decrypt the second file when the DRM key is purchased.

7. The method of claim 1, further comprising:

receiving, with the user device, the second portion of the media content when the first portion of the media content is presented.

8. The method of claim 7, wherein the retrieving comprises:

receiving, with the user device, the second portion of the media content when the DRM key is purchased.

9. The method of claim 1, further comprising:

displaying an option on the user device to purchase the second portion of the media content when the first media content is being presented or when the presentation of the first media content is completed.

10. The method of claim 1, further comprising:

transmitting, from the user device to a second device via at least one of a wireless and a wired communications link, at least the first portion of the media content.

11. The method of claim 10, wherein the transmitting further comprises:

transmitting, from the user device to the second device via at least one of the wireless and the wired communications link, the publically available key.

12. The method of claim 1, wherein the media content comprises at least one video content, audio content, text content, and game content.

13. The method of claim 12, wherein the presenting comprises at least one of displaying the video content, text content, and game content with a display of the user device and presenting the audio content with at least one speaker of the user device.

14. The method of claim 1, wherein the purchasing of the DRM key for the second portion of the media content comprises:

requesting payment from a user account associated with the user device when decrypting the second portion of the media content with the DRM key.

15. The method of claim 1, further comprising:

refunding a payment to a user account associated with the user device when decrypting the second portion of the media content with the DRM key has not occurred within a predetermined period of time.

16. The method of claim 1, wherein the purchasing of the DRM key for the second portion of the media content comprises:

requesting payment from a user account associated with the user device when decrypting the second portion of the media content with the DRM key.

17. An electronic device comprising:

a first communications interface to receive, via at least one of a wireless and a wired communication link, a media file having media content, the media content having a first portion and a second portion;

a user input device to receive a selection by a user of the received media content; and

a display to present the first portion of the media content when the first portion is unencrypted or to decrypt the first portion of the media content with a processor and a publically available key, and to present the second portion of the media content when the presentation of the first portion of the media content is complete and when a digital rights management (DRM) key is purchased to decrypt the second portion of the media content.

18. The electronic device of claim 17, wherein the media file received via the communications link comprises a single file having a first file block including the first portion of the media content and a second file block including the second portion of the media content.

19. The electronic device of claim 17, wherein the media file received via the communications link comprises a first file including the first portion of the media content, and a second file including a second portion of the media content.

20. The electronic device of claim 17, wherein the display of the electronic device displays a selectable option for a user to purchase the second portion of the media content when the first media content is being presented or when the presentation of the first media content is completed.
