Abstract

A system manages the allocation and storage of media content instance files in a storage device of a media client device. In one embodiment among others, the system includes logic for processing successive portions of received media content instances and storing received media content instances in the storage device as respective media content instance files; and a processor configured with the logic to track the size of media content instance files to provide an indication of available free space, such that the indication is independent of a first buffer space in the storage device.

Claims

1. A system for managing the storage of media content instances stored in a media client device, comprising:

at least one component including logic for receiving and processing successive portions of media content instances;

a storage device for storing received media content instances as media content instance files, each said respective media content instance file corresponding to a received media content instance comprising a single program, said storage device including a first buffer and a second buffer storing said received media content instances as media content instance files; and

a processor configured with logic for;

determining available storage space in the storage device for storing media content instances independent of space allocated for the first buffer; and

providing information indicating the available storage space, such that an indication in the provided information is independent of the size of the first buffer, and wherein the information is calculated based on a combination of a default bitrate value and an estimated value based on monitoring disk space consumed for downloaded media content.

2. The system of claim 1, wherein determining available storage space for storing media content corresponds to determining available storage space in the second buffer.

3. The system of claim 1, wherein the provided information is a visual indication of available storage space.

4. The system of claim 1, wherein the processor is further configured with logic to configure the respective sizes of the first buffer and second buffer.

5. The system of claim 1 wherein the first and second buffers correspond respectively for storage of first and second designations of media content instances.

6. The system of claim 5, wherein the processor is further configured with logic for designating the second designation to a first storage media instance file designated with the first designation, wherein the storage device includes the first storage media instance file.

7. The system of claim 6, wherein the designating of the second designation to the first storage media instance file is responsive to input from a user of the client media device.

8. The system of claim 5, wherein the second designation of media content instances correspond to a permanent recording operation.

9. A method for managing storage of media content instances in a media device, comprising the steps of:

storing received media content instances in the media device, wherein the media device includes a first buffer and a second buffer for storing received media content instances each comprising a single program;

determining available storage space in the media device for storing media content instances, wherein the determined available storage space is independent of space allocated for the first buffer; and

providing visual information corresponding to the available storage space independent of space allocated for the first buffer, and wherein the visual information is calculated based on a combination of a default bitrate value and an estimated value based on monitoring disk space consumed for downloaded media content.

10. The method of claim 9, wherein the first buffer corresponds to a time shift buffer.

11. The method of claim 10, wherein the second buffer corresponds to the storage of media content instances designated as permanent recordings.

12. The method of claim 11, wherein the determined available storage space for storing media content corresponds to available storage space in the second buffer.

13. The method of claim 11, wherein the first buffer corresponds to the storage of media content instances designated as buffered media content instances.

14. The method of claim 13, further comprising the steps of:

providing a first visual information corresponding to the available storage space after changing the designation of a first media content instance in the first buffer to a permanent designation, where the available storage space corresponding to the provided first visual information equal the available storage space corresponding to visual information prior to the designation of the first media content.

15. The method of claim 14, wherein the provided visual information corresponds to available storage space in the second buffer.

16. The method of claim 9, further comprising the steps of:

deleting a first media content instances in the first buffer, and providing a second visual information corresponding to the available storage space after the deletion of the first media content instance, wherein the available storage space corresponding to the second visual information also corresponds to the available storage space prior to the deletion of the first media content instance.

17. The method of claim 16, wherein the determined available storage space for storing media content corresponds to available storage space in the second buffer.

18. A method for managing storage of media content instances in a media device, comprising:

receiving media content instances each comprising a single program in the media device, said media device including a first buffer and a second buffer for storing received media content instances, wherein the first buffer is designated for storing buffered media content instances and the second buffer is designated for storing permanent media content instances; and

providing visual information corresponding to available storage space in the media device for storing media content instances, wherein the provided visual information comprises space allocated for the first buffer, and wherein the visual information further includes storage space calculated based on a combination of a default bitrate value and an estimated value based on monitoring disk space consumed for downloaded media content.

19. The method of claim 18, wherein the storage of successive portions of received media content instances in first or second buffers is structured according to storage units, wherein each storage unit respectively comprises the same number of plural basic storage units that are physically contiguous.

20. The method of claim 18, further comprising the step of storing and transferring in a third buffer of the media device the successive portions of each respective media content instance being received in the media device, said third buffer different than the first and second buffers.
