Abstract

The disclosed computer-implemented method may include receiving, from a client device, a request for multimedia content, where the request includes both a manifest request that includes client identification data and a license request that includes a license challenge. The method may further include validating the received request for multimedia content using the client identification data in the manifest request and generating a manifest response that includes an identification of a specified multimedia content stream that is to be provided to the client device. The method may also include acquiring at least one license in response to the license request, where the license includes a response to the license challenge having various content keys, and then providing the specified multimedia content stream, including the generated manifest response and the acquired license, to the client device. Various other methods, systems, and computer-readable media are also disclosed.

First claim

What is claimed is:

1. A computer-implemented method comprising:
receiving, from a client device, a request for a specific flavor of multimedia content that is stored on one or more content delivery nodes, the request comprising both a manifest request having client identification data and a license request that includes a license challenge;
validating the received request for the specified flavor of multimedia content using the client identification data in the manifest request;
generating a manifest response that includes an identification of a specified multimedia content stream that corresponds to the specified flavor of multimedia content;
performing in parallel:
determining which content delivery node has the specified flavor of multimedia content stored thereon; and
acquiring at least one license in response to the license request, the license including a response to the license challenge; and

providing the specified multimedia content stream from the determined content delivery node, including the generated manifest response and the acquired license, to the client device.

2. The computer-implemented method of claim 1 , wherein the specified flavor of multimedia content specifies at least one of: content title, content language, playback device type, playback resolution, encoding type, or audio format.

3. The computer-implemented method of claim 2 , wherein the corresponding multimedia content stream includes at least one of the specified content title, content language, playback device type, playback resolution, encoding type, or audio format.

4. The computer-implemented method of claim 1 , wherein determining which content delivery node has the specified flavor of multimedia content stored thereon includes querying a plurality of content delivery nodes in a content delivery network.

5. The computer-implemented method of claim 1 , wherein the request for the specified flavor of multimedia content received from the client device comprises a prefetch request, and wherein the license acquired in response to the license request comprises a limited duration license.

6. The computer-implemented method of claim 1 , wherein the request for the specified flavor of multimedia content received from the client device comprises a standard request, and wherein the license acquired in response to the license request comprises a standard duration license.

7. The computer-implemented method of claim 1 , wherein the license challenge includes one or more content keys.

8. The computer-implemented method of claim 7 , wherein the content keys provided in the license response to the license challenge are identified based on information received in the manifest request from the client device.

9. The computer-implemented method of claim 1 , wherein the manifest request provided by the client device includes a specified minimum set of information needed to acquire the at least one license for the specified multimedia content stream.

10. The computer-implemented method of claim 9 , wherein the specified minimum set of information needed to acquire the at least one license for the specified multimedia content stream comprises a minimum set of information used by a digital rights management (DRM) application programming interface (API) to access the at least one license.

11. A system comprising:
at least one physical processor; and
physical memory comprising computer-executable instructions that, when executed by the physical processor, cause the physical processor to:
receive, from a client device, a request for a specific flavor of multimedia content that is stored on one or more content delivery nodes, the request comprising both a manifest request having client identification data and a license request that includes a license challenge;
validate the received request for the specified flavor of multimedia content using the client identification data in the manifest request;
generate a manifest response that includes an identification of a specified multimedia content stream that corresponds to the specified flavor of multimedia content;
perform in parallel:
determine which content delivery node has the specified flavor of multimedia content stored thereon; and
acquire at least one license in response to the license request, the license including a response to the license challenge; and

provide the specified multimedia content stream from the determined content delivery node, including the generated manifest response and the acquired license, to the client device.

12. The system of claim 11 , further comprising implementing one or more heuristics to predict which multimedia content a user will select from a set of available multimedia content items.

13. The system of claim 12 , further comprising preemptively acquiring one or more multimedia content licenses based on which multimedia content items the user is predicted to select.

14. The system of claim 11 , further comprising receiving and implementing a previously used license challenge from the client device, allowing the client device to avoid minting at least one license challenge.

15. The system of claim 11 , wherein the specified flavor of multimedia content specifies at least one of: content title, content language, playback device type, playback resolution, encoding type, or audio format.

16. The system of claim 15 , wherein the corresponding multimedia content stream includes at least one of the specified content title, content language, playback device type, playback resolution, encoding type, or audio format.

17. The system of claim 11 , wherein determining which content delivery node has the specified flavor of multimedia content stored thereon includes querying a plurality of content delivery nodes in a content delivery network.

18. The system of claim 11 , wherein the request for the specified flavor of multimedia content received from the client device comprises a prefetch request, and wherein the license acquired in response to the license request comprises a limited duration license.

19. The system of claim 11 , wherein the request for the specified flavor of multimedia content received from the client device comprises a standard request, and wherein the license acquired in response to the license request comprises a standard duration license.

20. A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:
receive, from a client device, a request for a specific flavor of multimedia content that is stored on one or more content delivery nodes, the request comprising both a manifest request having client identification data and a license request that includes a license challenge;
validate the received request for the specified flavor of multimedia content using the client identification data in the manifest request;
generate a manifest response that includes an identification of a specified multimedia content stream that corresponds to the specified flavor of multimedia content;
perform in parallel:
determine which content delivery node has the specified flavor of multimedia content stored thereon; and
acquire at least one license in response to the license request, the license including a response to the license challenge; and

provide the specified multimedia content stream from the determined content delivery node, including the generated manifest response and the acquired license, to the client device.
