Abstract

A method for use in providing content that is made up of data includes providing a first portion of the data making up the content to a user, and making available for a limited amount of time an ability to stream a second portion of the data making up the content to a device having the first portion of the data. The second portion of the data includes essential information for reconstructing the content from the first portion of the data. Also disclosed are a storage medium storing a computer program for causing a processor based system to assist with providing content, and a system for use in providing content.

Claims

1. A method comprising:

partitioning content being constituted of a set of data according to a method of partitioning, such that the set of data is partitioned into a first portion of data and a second portion of data;

providing the first portion of the data to a user, wherein the first portion of the data comprises a data identification (ID); and

making available for a limited amount of time an ability to stream the second portion of the data to a device having the first portion of the data;

wherein the second portion of the data includes essential information for reconstructing the content;

wherein the making available the ability to stream the second portion of data is performed by a processor-based machine and comprises receiving the data ID and using the data ID to determine whether streaming the second portion of the data is authorized; and

wherein neither a device ID nor a user ID are used to determine whether streaming the second portion of the data is authorized.

2. A method in accordance with claim 1, wherein the first portion of the data is provided to the user on a physical storage medium.

3. A method in accordance with claim 1, wherein the first portion of the data is provided to the user by downloading.

4. A method in accordance with claim 1, wherein the first portion of the data is provided to the user via a peer-to-peer (P2P) file sharing scheme.

5. A method in accordance with claim 1, wherein the step of making available for a limited amount of time an ability to stream a second portion of the data further comprises making such stream available pursuant to a rental arrangement.

6. A method in accordance with claim 5, wherein the rental arrangement specifies the limited amount of time.

7. A method in accordance with claim 1, wherein the step of making available for a limited amount of time an ability to stream a second portion of the data further comprises making such stream available pursuant to a purchase arrangement.

8. A method in accordance with claim 1, wherein the step of making available for a limited amount of time an ability to stream a second portion of the data further comprises making only one such stream available at a time for the data ID.

9. A method in accordance with claim 1, wherein the first portion of the data is given to the user for free.

10. A method in accordance with claim 1, further comprising:

presenting an offer to the user for receiving the streamed second portion of the data when it is determined that streaming the second portion of the data is not authorized.

11. A non-transitory storage medium storing a computer program executable by a processor based system, the computer program causing the processor based system to execute steps comprising:

receiving from a device having a first portion of data corresponding to a content an indication that the device is attempting to play the content, the content being constituted of a set of data being partitioned into the first portion of data and a second portion of data; and

making available for a limited amount of time an ability to stream the second portion of the data to the device;

wherein the second portion of the data includes essential information for reconstructing the content;

wherein the making available the ability to stream the second portion of the data comprises;

receiving a data identification (ID) that is included in the first portion of the data and determining whether the streaming of the second portion is authorized based on the data ID, and

making available the ability to stream the second portion of the data when it is determined that the streaming the second portion of the data is authorized;

wherein neither a device ID nor a user ID are used to determine whether streaming the second portion of the data is authorized.

12. A non-transitory storage medium in accordance with claim 11, wherein the step of making available for the limited amount of time an ability to stream the second portion of the data further comprises making such stream available pursuant to a rental arrangement.

13. A non-transitory storage medium in accordance with claim 12, wherein the rental arrangement specifies the limited amount of time.

14. A non-transitory storage medium in accordance with claim 11, wherein the determining whether the streaming the second portion of the data is authorized comprises:

using the data ID to determine an allowed number of streams corresponding to the data ID, wherein the allowed number of streams comprises one of a number of streams at a given time and a total number of streams; and

wherein the determining whether the streaming the second portion of data is authorized comprises determining whether the number of streams provided at the time of receiving the indication that the device is attempting to play the content is less than or equal to the allowed number of streams.

15. A non-transitory storage medium in accordance with claim 11, wherein the step of making available for the limited amount of time an ability to stream the second portion of the data further comprises making only one such stream available at a time for the data ID.

16. A non-transitory storage medium in accordance with claim 11, further comprising sending information to the device for presenting an offer to a user for receiving the streamed second portion of the data when it is determined that the streaming the second portion of the data is not authorized.

17. A system comprising:

means for partitioning content being constituted of a set of data according to a method of partitioning, such that the set of data is partitioned into a first portion of data and a second portion of data;

means for providing the first portion of the data to a user, wherein the first portion of the data comprises a data identification (ID); and

a processor based system configured to make available for a limited amount of time an ability to stream the second portion of the data to a device having the first portion of the data;

wherein the second portion of the data includes essential information for reconstructing the content; and

wherein the processor based system configured to make available the ability to stream the second portion of data is configured to execute steps comprising;

receiving the data ID and determining whether streaming the second portion of the data is authorized using the data ID; and

making available the ability to stream the second portion of data when it is determine that the streaming is authorized;

wherein neither a device ID nor a user ID are used to determine whether streaming the second portion of the data is authorized.

18. A system in accordance with claim 17, wherein the means for providing the first portion of the data comprises a system for providing to the user one or more physical storage mediums that include the first portion of the data.

19. A system in accordance with claim 17, wherein the means for providing the first portion of the data comprises a system for allowing the user to download the first portion of the data.

20. A system in accordance with claim 17, wherein the means for providing the first portion of the data comprises a peer-to-peer (P2P) file sharing scheme.

21. A system in accordance with claim 17, wherein the processor based system is further configured to make available the ability to stream the second portion of the data pursuant to a rental arrangement.

22. A system in accordance with claim 21, wherein the rental arrangement specifies the limited amount of time.

23. A system in accordance with claim 17, wherein the processor based system is further configured to make available the ability to stream the second portion of the data pursuant to a purchase arrangement.

24. A system in accordance with claim 17, wherein the processor based system is further configured to make available only one stream of the second portion of the data at a time for the data ID.

25. A system in accordance with claim 17, wherein the processor based system is further configured to present an offer to the user for receiving the streamed second portion of the data when it is determined that streaming the second portion of the data is not authorized.
