Abstract

Electronic devices such as media players are configured for participation in activities relating to local, peer-to-peer distribution of digital content. In an exemplary distribution transaction, digital content items such as audio files, video files, text files, multimedia files, data files, playlists, and metadata are distributable between a source device and a sink device based on the acts of: identifying digital content item(s); determining the proximity of the source device to the sink device; and if the potential source and sink communication devices are deemed to be in proximity, establishing a peer-to-peer communication session (using a predetermined communication protocol such as Wireless Fidelity (“WiFi”), Bluetooth, or HiperLAN) between the source and sink devices. The digital content item(s) can be asynchronously distributed, via the peer-to-peer communication session, from a computer-readable medium accessible by the source communication device to a computer-readable medium associated with the sink communication device.

Claims

1. A system for distributing digital content, the system comprising:

a device discovery engine configured to determine if a source communication device operable by a source entity is proximate a sink communication device operable by a sink entity, independent of whether the source entity and the sink entity have a common predetermined affiliation;

a network communication interface responsive to the device discovery engine, the network communication interface configured to use a predetermined communication protocol to establish a peer-to-peer connection between the source communication device and the sink communication device if the source communication device is proximate the sink communication device; and

a digital content distribution engine responsive to the device discovery engine and the network communication interface, the digital content distribution engine configured to identify a digital content item stored on a computer-readable memory, and to manage asynchronous distribution of the digital content item via the peer-to-peer connection.

2. The system according to claim 1, wherein if the source communication device is proximate the sink communication device, the digital content distribution engine arranges for automatic distribution of the digital content item via the peer-to-peer connection.

3. The system according to claim 1, wherein if the source communication is proximate the sink communication device, the digital content distribution engine arranges for distribution of the digital content item via the peer-to-peer connection based on a request initiated by the sink entity.

4. The system according to claim 3, wherein the request initiated by the sink entity is for a one-time download of the digital content item.

5. The system according to claim 3, wherein the request initiated by the sink entity is for a subscription to the digital content item.

6. The system according to claim 1, further comprising:

a user interface responsive to the digital content distribution engine, the user interface configured to facilitate identification of the digital content item by the sink entity.

7. The system according to claim 6, wherein the user interface comprises:

a display area for displaying information associated with the source entity; and

at least one control selectable by the sink entity for selecting the information associated with the source entity.

8. The system according to claim 7, wherein the information associated with the source entity comprises a digital content item stored on the computer-readable memory, and wherein the at least one control is usable to request receipt of the digital content item.

9. The system according to claim 7, wherein the information associated with the source entity comprises an identity of the source entity.

10. The system according to claim 1, wherein the electronic device is selected from the group consisting of:

a digital media player;

a personal computer, a personal digital assistant, and a mobile phone.

11. The system according to claim 1, further comprising:

a user interface responsive to the digital content distribution engine, the user interface configured to facilitate identification of the digital content item by the source entity.

12. The system according to claim 11, wherein the user interface comprises:

a first display area for displaying information associated with a plurality of digital content items stored on the computer-readable memory; and

at least one control selectable by the source entity for selecting at least one digital media information item from the plurality of digital content items, the at least one digital media information item available for distribution by the source entity.

13. An electronic device, comprising:

a device discovery engine configured to detect a proximate electronic device;

a network communication interface responsive to the device discovery engine and configured to use a predetermined communication protocol to establish a peer-to-peer connection with a detected proximate electronic device;

a computer-readable medium having a digital content item stored thereon; and

a processor responsive to the computer-readable storage medium and to computer-executable instructions, the computer-executable instructions executable by the processor to;

ascertain whether a proximate electronic device has been detected by the device discovery engine;

if a proximate electronic device has been detected, cause the network communication interface to establish a peer-to-peer connection with the detected proximate electronic device, independent of whether the proximate electronic device has a predetermined affiliation;

indicate to the detected proximate electronic device that the digital content item is available for distribution;

receive a request for transfer of the digital content item from the proximate electronic device; and

based on the received request, arrange for asynchronous transfer of the digital content item from the computer-readable medium to the proximate electronic device via the peer-to-peer connection.

14. The electronic device according to claim 13, wherein the request for transfer is initiated by an entity operating the proximate electronic device.

15. The electronic device according to claim 13, wherein the request for transfer is automatically initiated by the proximate electronic device without action from an entity operating the proximate electronic device.

16. The system according to claim 13, further comprising:

a user interface configured to facilitate identification of the digital content item by an entity operating the electronic device.

17. An electronic device, comprising:

a device discovery engine configured to detect a proximate electronic device;

a network communication interface configured to use a predetermined communication protocol to establish a peer-to-peer connection with a detected proximate electronic device;

a computer-readable medium; and

a processor responsive to the computer-readable medium and to computer-executable instructions, the computer-executable instructions executable by the processor to;

ascertain whether a proximate electronic device has been detected by the device discovery engine;

if a proximate electronic device has been detected, cause the network communication interface to establish a peer-to-peer connection with the detected proximate electronic device, independent of whether the proximate electronic device has a predetermined affiliation;

determine whether a digital content item is available for transfer from the proximate electronic device;

based on the determination, request transfer of the digital content item from the proximate communication device;

asynchronously receive the digital content item from the proximate communication device via the established peer-to-peer connection; and

store the digital content item on the computer-readable medium.

18. The electronic device according to claim 17, wherein the request for transfer is initiated by an entity operating the electronic device.

19. The electronic device according to claim 17, wherein the request for transfer is automatically initiated by the electronic device without action from an entity operating the electronic device.

20. The system according to claim 17, further comprising:

a user interface configured to facilitate a determination by an entity operating the electronic device whether the digital content item is available for transfer from the proximate electronic device.
