Abstract

Methods and devices for end-user generation of content previews by selecting digital content stored on a communications device, generating a content preview on the communications device from the digital content selected based on content transcoding information. In one embodiment, a mobile wireless communications device (300) includes a content preview generator (340) for generating content previews from content stored in memory based on content transcoding information, and a transmitter (380) for sharing the content previews from the mobile wireless communications device, for example in peer-to-peer communications.

Claims

1. A method for transferring digital content in peer-to-peer communications between a first peer communications device and a second peer communications device, comprising:

selecting digital content stored on the first peer communications device,

generating a content preview, at the first peer communications device, from the digital content selected,

transmitting the content preview from the first peer communications device to the second peer communications device.

2. The method of claim 1,

generating the content preview based upon corresponding content transcoding information,

the content transcoding information specifying limitations on content preview generation.

3. The method of claim 1, generating the content preview by selecting a portion of the digital content selected for inclusion in the content preview from a user interface of the first peer communications device.

4. The method of claim 1, generating a plurality of at least two different content previews, at the first peer communications device, from the same digital content selected.

5. The method of claim 4, generating a plurality of at least two different content previews, at the first peer communications device, by selecting different portions of the selected digital content for inclusion in the corresponding content previews.

6. The method of claim 4, transmitting the plurality of at least two different content previews from the first peer communications device to at least one other peer communications devices.

7. The method of claim 1,

the first peer communications device possessing a right to the digital content and a right to distribute the content preview generated,

transmitting the content preview from the first peer communications device to the second peer communications device without relinquishing the right to the digital content.

8. A method in a mobile wireless communications device, comprising:

selecting digital content stored on the mobile wireless communications device,

the mobile wireless communications device possessing a right to generate a content preview from the digital content selected;

generating a content preview, on the mobile wireless communications device, from the digital content selected.

9. The method of claim 8, generating the content preview within content preview generation limitations specified for the digital content selected.

10. The method of claim 9, receiving the digital content and the content transcoding information at a receiver of the wireless communications device.

11. The method of claim 8, generating the content preview by selecting a portion of the selected digital content for inclusion in the content preview from a user interface of the mobile wireless communications device.

12. The method of claim 8, generating a plurality of at least two different content previews, on the mobile wireless communications device, from the same digital content selected.

13. The method of claim 12, generating the plurality of at least two different content previews based on content transcoding information stored on the mobile wireless communications device, the content transcoding information specifying content preview generation limitations for the digital content selected.

14. The method of claim 13, generating the plurality of content previews by selecting different portions of the selected digital content for inclusion in different content previews from a user interface of the mobile wireless communications device.

15. The method of claim 8,

generating a plurality of at least two different content previews, on the mobile wireless communications device, for the same digital content selected,

at least two of the plurality of different content previews including different portions of the same digital content selected.

16. The method of claim 10,

the mobile wireless communications device possessing a right to the digital content and a right to distribute the content preview generated,

transmitting the content preview from the mobile wireless communications device without relinquishing the right to the digital content.

17. A method in a mobile wireless communications device, comprising:

selecting digital content stored on the mobile wireless communications device,

generating a plurality of different content previews, on the mobile wireless communications device, from the same digital content selected.

18. A mobile wireless communications device, comprising:

digital content and corresponding content transcoding information stored in memory,

the content transcoding information specifying parameters for generating content previews from corresponding digital content;

a content preview generator,

the content preview generator generating content previews from content stored in memory based on the content transcoding information;

a transmitter for sharing the content previews from the mobile wireless communications device.

19. The mobile wireless communications device of claim 18,

the content transcoding information specifying whether content previews may be generated,

the content preview generator generating content previews for the digital content selected only if the content transcoding information specifies that content previews may be generated.

20. A digital content transcoding data structure enabling content previews to be generated from digital content at mobile wireless communications devices, comprising:

digital content identification associating the digital content transcoding data structure with corresponding digital content;

digital content preview generation information specifying limitations on user generated content previews for the corresponding digital content with which the digital content transcoding data structure is associated.

21. The digital content transcoding data structure of claim 20,

at least one of the digital content preview generation limitations specifying portions of the digital content which may be selected by content preview creators for inclusion in content previews generated for the corresponding digital content with which the digital content transcoding data structure is associated.
