Abstract

Provided are methods and systems for reducing content storage space and network resources. A device, such as a network storage device, can receive a plurality of requests to record a content item with varying start times and end times. The network device can map the start time and end time of each request to a subscriber, premises, and/or device. The network device can determine the earliest of the start times associated with the content item and the latest of the end times associated with the content item. In an aspect, the network device can make a recording, starting at the earliest start time and ending at the latest end time.

First claim

What is claimed is:

1. An apparatus, comprising:
one or more processors; and
a memory storing processor executable instructions that, when executed by the one or more processors, cause the apparatus to:
receive, based on a plurality of start offset options associated with a content item, a plurality of requests to store the content item, wherein the plurality of requests comprises a plurality of start times associated with one or more of the plurality of start offset options and further comprises a plurality of end times associated with the content item;
determine an earliest start time of the plurality of start times, and a latest end time of the plurality of end times;
store, for each of the plurality of requests, an instance of the content item starting at the determined earliest start time and ending at the determined latest end time;
receive a play request for the content item comprising a start time later than the determined earliest start time and an end time earlier than the determined latest end time; and
send, based on the play request, the content item, wherein a portion of the content item earlier than the requested start time is not sent, and wherein a portion of the content item later than the requested end time is not sent.

2. The apparatus of claim 1 , wherein the processor executable instructions, when executed by the one or more processors, further cause the apparatus to delete all instances of the content item except the stored instance of the content item.

3. The apparatus of claim 1 , wherein the plurality of start offset options comprises a plurality of times occurring before a start time associated with the content item and a plurality of times occurring after the start time associated with the content item.

4. The apparatus of claim 1 , wherein the content item is a live program.

5. The apparatus of claim 1 , wherein each of the plurality of start offset options is an offset of time before the content item is scheduled to start.

6. The apparatus of claim 1 , wherein each of the plurality of end times is one of a plurality of selectable options from a list, wherein each selectable option of the plurality of selectable options is an offset of time after the content item is scheduled to end.

7. The apparatus of claim 1 , wherein the plurality of requests to store the content item comprises a plurality of requests to store the content item at one or more of the following intervals: daily or weekly.

8. The apparatus of claim 1 , wherein the processor executable instructions, when executed by the one or more processors, further cause the apparatus to crop each instance of the stored content item, wherein each instance represents an instance of a program, wherein each cropped instance begins at the start of the program, and wherein each cropped instance ends at the end of the program.

9. An apparatus, comprising:
one or more processors; and
a memory storing processor executable instructions that, when executed by the one or more processors, cause the apparatus to:
receive, based on a plurality of start offset options associated with a content item, a first request to store an instance of the content item, wherein the first request comprises a first start offset associated with the plurality of start offset options and a first end offset;
store a first version of the content item in a first content file, wherein the first content file represents a portion of the content item occurring between and including the first start offset and the first end offset;
receive a second request to store another instance of the content item, wherein the second request comprises a second start offset and a second end offset, wherein the second start offset is less than the first start offset, wherein the second end offset is less than the first end offset;
determine that the first version of the content item has already been stored, that the second start offset is less than the first start offset, and that the second end offset is less than the first end offset;
store a second version of the content item in a second content file, wherein the second content file represents a portion of the content item occurring between and including the second start offset and the second end offset;
receive a request for the content item, wherein the request comprises a start offset greater than the first start offset and an end offset greater than the first end offset; and
send, based on the request for the content item, the first content file, wherein a portion of the content item between the requested start offset and the first start offset is not sent, and wherein a portion of the content item between the requested end offset and the first end offset is not sent.

10. The apparatus of claim 9 , wherein one or more of the first start offset, the first end offset, the second start offset, or the second end offset are determined by one or more users.

11. The apparatus of claim 9 , wherein the apparatus comprises a cloud digital video recorder.

12. The apparatus of claim 9 , wherein the processor executable instructions that, when executed by the one or more processors, cause the apparatus to determine that the first version of the content item has already been stored further cause the apparatus to match an identifier associated with the content item to stored information.

13. The apparatus of claim 9 , wherein the processor executable instructions, when executed by the one or more processors, further cause the apparatus to delete the second content file.

14. The apparatus of claim 9 , wherein the processor executable instructions, when executed by the one or more processors, further cause the apparatus to move the first content file to an archival storage.

15. The apparatus of claim 9 , wherein the content item is a live program.

16. The apparatus of claim 9 , wherein the processor executable instructions, when executed by the one or more processors, further cause the apparatus to crop the first version of the content item in the first content file, wherein the cropped first version of the content item is associated with a program, wherein the cropped first version of the content item begins at a start of the program, and wherein the cropped first version of the content item ends at an end of the program.

17. The apparatus of claim 9 , wherein the processor executable instructions, when executed by the one or more processors, further cause the apparatus to crop the second version of the content item in the second content file, wherein the cropped second version of the content item is associated with a program, wherein the cropped second version of the content item begins at a start of the program, and wherein the cropped second version of the content item ends at an end of the program.

18. An apparatus, comprising:
one or more processors; and
a memory storing processor executable instructions that, when executed by the one or more processors, cause the apparatus to:
receive, based on a plurality of start offset options associated with a stored content item, a request for the stored content item, wherein the request comprises a first start time associated with the plurality of start offset options and a first end time;
determine, based on the request, a second start time that is offset to a time after the first start time and a second end time that is offset to a time before the first end time;
determine a version of the stored content item that comprises the second start time and the second end time; and
send the version of the stored content item, wherein a
