Abstract

Various aspects of the invention provide a system, apparatus, and method of storing data in a storage device for use by one or more data processing devices, such as person video recorders, communicatively coupled to the data storage device. In a representative embodiment, the method comprises receiving data from the one or more personal video recorders, and storing the received data in the storage device, wherein the storage device acts as a centralized facility for storing data provided by the one or more personal video recorders. In a representative embodiment, a system for implementing a centralized storage mechanism used by one or more personal video recorders comprises a storage device comprising one or more storage drives and one or more switching devices that provides communicative coupling between the storage device and the one or more personal video recorders.

Claims

1. A method of implementing data storage for use by one or more personal video recorders comprising:

receiving data by said storage device provided by said one or more personal video recorders; and

storing said received data into one or more data storage drives of said storage device, said storage device acting as a centralized facility for storing, distributing, and sharing said data.

2. The method of claim 1 wherein said one or more personal video recorders comprises one or more data storage drives.

3. The method of claim 2 wherein said data storage drives comprises hard disk drives.

4. The method of claim 1 wherein said one or more personal video recorders lacks a data storage medium.

5. The method of claim 1 further comprising performing data striping of said received data using said storage device.

6. The method of claim 5 wherein said data striping utilizes hard disk drives of different sizes.

7. The method of claim 5 wherein said data striping comprises implementing RAID 0.

8. The method of claim 1 further comprising performing data mirroring of said received data using said storage device.

9. The method of claim 8 wherein said data mirroring utilizes hard disk drives of different sizes.

10. The method of claim 8 wherein said data mirroring comprises implementing RAID 1.

11. The method of claim 1 wherein said data comprises audiovisual or multimedia data.

12. A method of providing data storage for a PVR ready set-top-box, said PVR ready set-top-box implemented without a data storage medium, said method comprising adding a storage device to a network, said storage device communicatively coupled to said PVR ready set-top-box by way of said network, said PVR ready set-top-box capable of storing data into said storage device, said PVR ready set-top-box capable of reading data from said storage device.

13. The method of claim 12 wherein said storage device comprises one or more hard disk drives.

14. The method of claim 12 wherein said storage device implements RAID 0.

15. The method of claim 12 wherein said storage device implements RAID 1.

16. The method of claim 12 wherein said storage device implements RAID 0+1 or RAID 10.

17. A method of expanding data storage capacity to a personal video recorder comprising adding a data storage device to a network, said data storage device communicatively coupled to said personal video recorder by way of said network.

18. The method of claim 17 wherein said data storage device comprises one or more data storage drives.

19. The method of claim 18 wherein said one or more data storage drives comprises one or more hard disk drives.

20. A system for implementing a centralized data storage mechanism for use by one or more personal video recorders comprising:

a storage device comprising one or more data storage drives; and

one or more switching devices, said one or more switching devices providing communicative coupling between said storage device and said one or more personal video recorders.

21. The system of claim 20 wherein said one or more data storage drives comprises one or more hard disk drives.

22. The system of claim 20 wherein a data pool may be implemented over said one or more data storage drives.

23. An apparatus for storing data comprising:

a memory;

a set of software instructions resident within said memory;

one or more data storage drives used to store said data, said data utilized by one or more personal video recorders (PVRs), said apparatus communicatively coupled to said one or more personal video recorders; and

a controller capable of executing said set of instructions resident in said memory, said executing allowing the pooling of data to occur over said one or more data storage drives.

24. The apparatus of claim 23 wherein said one or more personal video recorders comprises one or more data storage drives.

25. The apparatus of claim 23 wherein said one or more personal video recorders lacks a data storage drive.

26. The apparatus of claim 23 wherein said one or more data storage drives comprises one or more hard disk drives.
