Abstract

Improved techniques to restrict sharing of media assets over a network are disclosed. A server computer having media assets can permit one or more clients to receive access to such media assets over a computer network. However, the access to such media assets can be restricted based on numerical limits as well as temporal limits. The media assets are digital media assets, such as audio items (e.g., audio files, including music or songs), videos (e.g., movies) or images (e.g., photos).

Claims

1. A method of managing sharing of media content from a server computer to one or more client computers across a computer network, said method comprising:

(a) receiving a connection request from a particular one of the client computers to receive media content from the server computer;

(b) determining whether at least one of a limited number of client slots is available for use by the particular client computer;

(c) assigning an available one of the client slots for use by the particular client computer when said determining (b) determines that at least one of a limited number of client slots is available for use by the particular client computer;

(d) establishing a connection for the particular client computer using the assigned client slot;

(e) determining when the connection for the particular client computer has ended or is to be ended; and

(f) reserving the assigned client slot for the particular client computer for at least a predetermined period of time after the connection for the particular client computer has ended.

2. A method as recited in claim 1, wherein, while connected using the assigned client slot, the particular client computer can receive media content being shared by the server computer over the computer network.

3. A method as recited in claim 2, wherein the computer network is a local area network.

4. A method as recited in claim 2, wherein the media content is being shared over the computer network by streaming the media content.

5. A method as recited in claim 1, wherein the client slots that are assigned or reserved are associated with particular client computers.

6. A method as recited in claim 1, wherein the particular client computer is distinguished from other client computers using a unique client identifier.

7. A method as recited in claim 1, wherein each of the clients slots are deemed available for use by the particular client computer when open or when reserved for the particular client computer.

8. A method as recited in claim 1, wherein said determining (b) making available a client slot that was previously reserved if the client slot has been reserved for more that the predetermined period of time.

9. A method as recited in claim 1, wherein the server computer is a personal computer operating as a music server, and wherein the one or more client computers are music clients.

10. A method for restricted sharing of media content from a server computer to one or more client computers across a computer network, said method comprising:

(a) receiving, from a particular one of the client computers, a login request to the server computer;

(b) obtaining a unique identifier associated with the particular client computer;

(c) determining whether any of a plurality of limited client slots are reserved for use by particular client computers;

(d) assigning the client slot to the particular client computer when said determining (c) determines that at least one of the limited client slots is reserved for the particular client computers; and

(e) granting the login request when the particular client device has been assigned one of the limited client slots.

11. A method as recited in claim 10, wherein said method further comprises:

(f) determining whether any of the limited client slots are unassigned to any of the client computers; and

(g) assigning the client slot to the particular client computer when said determining (f) determines that at least one of the limited client slots is unassigned to any of the client computers.

12. A method as recited in claim 11, wherein said assigning (g) operates to assign the client slot only if said assigning (d) does not assign the client slot.

13. A method as recited in claim 11, wherein said method further comprises:

(h) determining whether any of the limited client slots that are reserved for the particular client computers have been reserved for more than a predetermined reservation period; and

(i) assigning a client slot that has been reserved for more that the predetermined reservation period to the particular client computer when said determining (h) determines that at least one of the limited client slots has been reserved for more than the predetermined reservation period.

14. A method as recited in claim 13, wherein said assigning (i) operates to assign the client slot only if said assigning (d) and (g) do not assign the client slot.

15. A method as recited in claim 11, wherein said method further comprises:

(f) determining whether any of the limited client slots that are reserved for the particular client computers have been reserved for more than a predetermined reservation period; and

(g) assigning a client slot that has been reserved for more that the predetermined reservation period to the particular client computer when said determining (f) determines that at least one of the limited client slots has been reserved for more than the predetermined reservation period.

16. A method as recited in claim 15, wherein said assigning (g) operates to assign the client slot only if said assigning (d) does not assign the client slot.

17. A method as recited in claim 10, wherein said method further comprises:

(f) determining when the particular client computer is logged out, has logged out or is about to be logged out; and

(g) reserving the assigned client slot for the particular client computer for at least a predetermined reservation period after the logout of the particular client computer.

18. A method as recited in claim 17, wherein said reserving (g) includes at least storing a reservation indication at the server computer for the assigned client slot, the reservation indication including at least a time indication and a unique identifier for the particular client computer.

19. A method as recited in claim 10, wherein the media content pertains to music, and

wherein the server computer is a personal computer operating as a music server, and wherein the one or more client computers are music clients.

20. A method as recited in claim 19, wherein the computer network is a local area network, wherein the media content is being shared over the computer network by streaming the media content.

21. A method as recited in claim 19, wherein the particular client computer is distinguished from other client computers using a unique client identifier.

22. A computer readable medium including at least computer program code for managing sharing of media content from a server computer to one or more client computers across a computer network, said computer readable medium comprising:

computer program code for receiving a connection request from a particular one of the client computers to receive media content from the server computer;

computer program code for determining whether at least one of a limited number of client slots is available for use by the particular client computer;

computer program code for assigning an available one of the client slots for use by the particular client computer when said computer program code for determining determines that at least one of a limited number of client slots is available for use by the particular client computer;

computer program code for establishing a connection for the particular client computer using the assigned client slot;

computer program code for determining when the connection for the particular client computer has ended or is to be ended; and

computer program code for reserving the assigned client slot for the particular client computer for at least a predetermined period of time after the connection for the particular client computer has ended.

23. A computer readable medium as recited in claim 22,

wherein, while connected using the assigned client slot, the particular client computer can receive media content being shared by the server computer over the computer network,

wherein the media content is being shared over the computer network by streaming the media content, and

wherein the computer network is a local area network.

24. An electronic device, comprising:

a network interface for coupling said electronic device to a computer network;

a memory for storing media content;

a media management module operable to permit limited sharing of at least a portion of the media content stored in said memory to one or more other electronic devices coupled to the computer network,

wherein said media management module limits the sharing of at least a portion of the media content to a limited number of other electronic devices,

wherein when one of the other electronic devices is permitted to participate in the sharing, the one of the other electronic devices is deemed to be sharing, and

wherein when one of the other electronic devices has completed its participation in the sharing, the one of the other electronic devices is deemed to be reserved for sharing for at least a predetermined period of time, thereby restricting the sharing by different ones of the other electronic devices per unit time.
