Abstract

Methods and devices for end-user generation of content previews including selecting digital content stored on a communications device, and 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 with other mobile wireless communications devices, 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, the content preview generated based upon content transcoding information associated with content from which the content preview is generated,

the content transcoding information enabling generation of the content preview,

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 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.

3. 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.

4. The method of claim 3, 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.

5. The method of claim 3, transmitting the plurality of at least two different content previews from the first peer communications device to at least one other peer communications devices.

6. 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.

7. A mobile wireless communications device, comprising:

digital content and corresponding content transcoding information stored in memory,

the content transcoding information permitting and 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.

8. The mobile wireless communications device of claim 7, 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.
