Abstract

This disclosure describes systems and methods related to a cloud-enabled network-based digital video recorder. In some embodiments, a request to record an asset may be received from a client device. An asset record associated with the request may be created. A first record event for generation of a manifest file may be created. A second record event for entitlement validation of an asset may be created. A third record event for quality control for the asset may be created based at least in part on the asset record. A manifest file associated with the asset may be generated based at least in part on the asset record.

Claims

1. A computer-implemented method, comprising:

generating, by a network-based digital video recording (nDVR) system comprising one or more computers, a first time-shift buffer and a second time-shift buffer;

receiving, by the nDVR system from a user via a client device, a first group of content segments associated with a first live content in the first time-shift buffer;

receiving, by the nDVR system, a first request to record the first live content;

transforming, by the nDVR system, the first live content to a first recorded content asset based at least in part on the first group of content segments;

receiving, by the nDVR system, a second group of content segments associated with second live content in the second time-shift buffer;

receiving, by the nDVR system, while continuing to receive the first group of content segments, a second request to record the second live content; and

transforming, by the nDVR system, the second live content to a second recorded content asset based at let in part on the second group of content segments.

2. The computer-implemented method of claim 1, further comprising:

generating, by the nDVR system, a first manifest file associated with the first recorded content asset;

generating, by the nDVR system, a second manifest file associated with the second recorded content asset;

storing, by the nDVR system, the first manifest file in a directory associated with the user; and

storing, by the nDVR system, the second manifest file in the directory associated with the user.

3. The computer-implemented method of claim 1, wherein the first time-shift buffer is a user-based rolling recording for a predetermined duration.

4. The computer-implemented method of claim 1, wherein the second time-shift buffer is a user-based rolling recording for a predetermined duration.

5. The computer-implemented method of claim 1, wherein a duration associated with the first time-shift buffer is set as a subscription option selected by the user.

6. The computer-implemented method of claim 1, wherein a duration associated with the second time-shift buffer is set as a subscription option selected by the user.

7. The computer-implemented method of claim 1, wherein the first content segments are retrieved from the first time-shift buffer and stored in a directory associated with the user.

8. The computer-implemented method of claim 1, wherein the second content segments are retrieved from the second time-shift buffer and stored in a directory associated with the user.

9. A system comprising:

at least one memory storing computer-executable instructions; and

at least one processor, wherein the at least one processor is configured to access the at least one memory and to execute the computer-executable instructions to;

generate a first time-shift buffer and a second time-shift buffer;

receive, from a client device on behalf of a user, a first group of content segments associated with a first live content in the first time-shift buffer;

receive a first request to record the first live content;

transform the first live content to a first recorded content asset based at least in part on the first group of content segments;

receive, from the client device on behalf of the user, a second group of content segments associated with second live content in the second time-shift buffer;

receive, while continuing to receive the first group of content segments, a second request to record the second live content; and
