Abstract

The invention relates to the sharing of media clips, such as sound and video, among various computer systems without the sharing of the corresponding media clip files. A media clip may be shared by streaming the media clip within a peer-to-peer group. The users within the peer-to-peer group can be selected to provide a relative amount of privacy and security. A user can select media clip that is streamed remotely such that the user may have control over the content of the streamed media clip.

Claims

1. A media clip sharing system comprising:

a central server adapted to communicate with a plurality of user computers in a network, the central server being adapted to identify a first user through a sign-in process and at least temporarily storing a relationship between the first user and a first machine address in a memory, the central server being configured to provide the first machine address associated with the first user to a user computer operated by a second user, the first user and the second user being associated in a peer list;

a first user computer corresponding to the first machine address, where the first user computer is coupled with the central server and is configured to communicate with the central server as a client, the first user computer maintaining a media clip in local memory and being configured to send a stream of the media clip to another user computer; and

a second user computer coupled with the central server and configured to communicate with the central server as a client, the second user computer being configured to receive the first machine address from the central server such that the second user computer can communicate with the first user computer in a peer-to-peer network, and the second user computer being configured to receive and to play the stream of the media clip from the first user computer.

2. The media clip sharing system of claim 1, where the first user and the second user are the same user.

3. The media clip sharing system of claim 1, where the second user computer is further configured to receive indications of media clips that are available in the first user computer and to allow selection of the media clip that is to be streamed.

4. The media clip sharing system of claim 1, where the machine address is an Internet Protocol (IP) address.

5. The media clip sharing system of claim 1, wherein the first user computer and the second user computer are configured to communicate with each other with a connectionless protocol.

6. A method of receiving a media clip over a network by a first node comprising:

coupling the first node with the network;

communicating with a central node coupled with the computer network;

receiving an indication from the central node that a second node is coupled with the central node;

receiving a machine address of the second node;

using the machine address to communicate with the second node in a peer-to-peer architecture; and

receiving a stream of a media clip from the second node.

7. The method of claim 6, further comprising:

receiving an indication from the central node of a status of users in a peer list, where the status indicates whether a node associated with a user in the peer list is also in communication with the central node; and

selecting a node from the peer list as the second node.

8. The method of claim 6, where the receiving of the machine address of the second node occurs only when the first node and the second node are associated in a peer group.

9. The method of claim 6, further comprising providing a chat function from the first node to the second node at least while the media clip is streamed.

10. The method of claim 6, further comprising:

controlling the streaming at the first node; and

playing the media clip that is streaming at the first node and at the second node at substantially the same time.

11. The method of claim 10, wherein the controlling the streaming comprises at least one of initiating, terminating, pausing, skipping, rewinding, reversing, and fast forwarding of the streaming.

12. The method of claim 6, further comprising:

receiving a plurality of indications of media clips that are available to be streamed; and

selecting the media clip from the plurality of indications of media clips.

13. The method of claim 6, further comprising:

communicating with a plurality of nodes that are in communication with the central node;

receiving a plurality of indications of media clips that are available to be streamed; and

selecting the media clip from the plurality of indications of media clips.

14. The method of claim 6, further comprising streaming the media clip in a predetermined sequence with a plurality of media clips, where the plurality of media clips are stored in at least two different nodes that are coupled with the first node.

15. The method of claim 6, further comprising receiving the stream of the media clip from the second node to the first node only when the first node and the second node are in a peer group.

16. The method of claim 6, further comprising:

prompting the second node for authorization prior to receiving the stream of the media clip from the second node to the first node; and

receiving the stream the media clip in response to authorization from the second node.

17. A method of arranging a plurality of media clips in a playback sequence, the method comprising:

coupling with a first computer;

retrieving a first path and a first filename corresponding to a first media clip that is stored on the first computer;

adding the first path and first filename to the playback sequence;

coupling with a second computer;

retrieving a second path and a second filename corresponding to a second media clip that is stored on the second computer;

adding the second path and the second filename to the playback sequence; and

using the playback sequence to automatically initiate streaming of the first media clip from the first computer and the second media clip from the second computer.

18. The method of claim 17, where the first computer and the second computer area associated in a peer group, and further comprising confining the streaming of the first media clip and the second media clip to a user computer that is also associated in the peer group.

19. The method of claim 17, further comprising automatically detecting an absence of the first computer and automatically reconfiguring the playback sequence to exclude media clips that correspond to the first computer.

20. The method of claim 17, further comprising:

forming peer-to-peer communication paths with the first computer and with the second computer; and

receiving the first media clip and the second media clip via the peer-to-peer communication paths.

21. A method of sharing media over a network comprising:

coupling a first user computer and a second user computer in a peer-to-peer architecture;

allowing a user to select a media clip from the first user computer;

streaming a media clip from the first user computer to the second user computer; and

playing back the media clip while the media clip is streamed from the first user computer to the second user computer, the playing back occurring on both the first user computer and on the second user computer at substantially the same time.

22. The method of claim 21, further comprising providing a chat function between the first user computer and the second user computer while the media clip is played.

23. A method performed by a first node of sending a media clip over a network, the method comprising:

establishing a connection to a computer network with the first node;

communicating with a central node, where the central node is coupled with the computer network;

receiving a request from a second node for the media clip, said media clip being locally available to the first node;

receiving a machine address of the second node;

using the machine address to communicate with the second node in a peer-to-peer architecture; and
