Abstract

Performance evaluation of a storage device, for example a storage device connected to a Set Top Box, for evaluating its suitability for supporting DVR/PVR functions such as recording a broadcast audio/video stream or time shifting a broadcast audio/video stream.

Claims

1. A method for evaluating performance of a storage device connected to a host device, wherein the method is implemented by said host device, the method comprising:

executing read-write tests on said storage device;

obtaining a performance profile of said storage device through measuring a read-write transfer bit rate of said storage device according to a result of said read-write tests, said performance profile indicating that said storage device has sufficient performance capabilities to be used as a device for storing and retrieving video data with a video resolution corresponding to said performance profile.

2. The method according to claim 1, wherein said read-write tests are binary read-write operations on a memory segment in said storage device.

3. The method according to claim 2, wherein contents of said memory segment are saved in said host device before executing said read-write tests and said saved contents are restored to said storage device after having executed said read-write tests.

4. The method according to claim 1, wherein said obtaining of said performance profile further comprises obtaining a maximum number of supported simultaneous read-write operations.

5. The method according to claim 1, wherein said video resolution is one of a standard definition video resolution, a high definition video resolution, or an ultra-high definition video resolution.

6. The method according to claim 4, wherein said performance profile further indicates a personal video recording type class, obtained from said maximum number of supported simultaneous read-write operations, said personal video recording type class being one of:

a recording or time shift class;

a recording and time shift class.

7. The method according to claim 1, wherein said performance profile is saved in said host device.

8. The method according to claim 1, wherein said performance profile is saved in a network storage area.

9. A host device for evaluating performance of a storage device connected to said host device, comprising a processor and memory configured to:

execute read-write tests on said storage device;

obtain a performance profile of said storage device through measuring a read-write transfer bit rate of said storage device according to a result of said binary read-write tests, said performance profile indicating that said storage device has sufficient performance capabilities to be used as a device for storing and retrieving video data with a video resolution corresponding to said performance profile.

10. The host device according to claim 9, wherein said processor and said memory are further configured to execute said read-write tests as binary read-write operations on a memory segment in said storage device.

11. The method according to claim 10, wherein said processor and said memory are further configured to save contents of said memory segment in said host device before executing said read-write tests and to restore said saved contents to said storage device after having executed said read-write tests.

12. The host device according to claim 9, wherein said processor and said memory are further configured to obtain a maximum number of supported simultaneous read-write operations in order to obtain said performance profile.

13. The host device according to claim 9, wherein said processor and said memory are further configured to save said performance profile in said host device.

14. The host device according to claim 9, wherein said processor and said memory are further configured to save said performance profile in a network storage area.

15. A non-transitory computer readable medium storing instructions configured to evaluate a performance of a storage device connected to a host device, and configured to perform at least the following:

executing read-write tests on said storage device;

obtaining a performance profile of said storage device through measuring a read-write transfer bit rate of said storage device according to a result of said read-write tests, said performance profile indicating that said storage device has sufficient performance capabilities to be used as a device for storing and retrieving video data with a video resolution corresponding to said performance profile.

16. The non-transitory computer readable medium according to claim 15, wherein said instructions are further configured to perform saving of contents of said memory segment in said host device before executing said read-write tests and restoring said saved contents to said storage device after having executed said read-write tests.

17. The non-transitory computer readable medium according to claim 15, wherein said instructions are further configured to perform obtaining of a maximum number of supported simultaneous read-write operations.

18. The non-transitory computer readable medium according to claim 17, wherein said instructions are further configured to perform indicating in said performance profile a personal video recording type class, obtained from said maximum number of supported simultaneous read-write operations, said personal video recording type class being one of:

a recording or time shift class;

a recording and time shift class.

19. The non-transitory computer readable medium according to claim 15, wherein said instructions are further configured to perform saving of said performance profile in said host device.

20. The non-transitory computer readable medium according to claim 15, wherein said instructions are further configured to perform saving of said performance profile in a network storage area.
