Abstract

Directing a content player to a content source is disclosed. A first manifest request from a client requesting content is received at a server. The manifest request includes information generated as a result of the client contacting a content management system and in response, receiving from the content management system information associated with the client and a direction to the server. Based at least in part on the received information, at least one of a bitrate and a content source is determined. Instructions are sent to the client based at least in part on the determination. The client is configured to obtain the requested content according to the instructions.

First claim

What is claimed is:

1. A system, comprising:
one or more processors configured to:
receive, at a content distribution coordinator, a manifest request from a client requesting content, wherein the client is configured to access the content distribution coordinator via a virtual resource locator provided to the client by a content management system, wherein the content management system provided the virtual resource locator to the client in response to the client having made a request to the content management system for content, and wherein the virtual resource locator provided to the client by the content management system encodes information including a plurality of content delivery networks at which the requested content is stored;
in response to the content distribution coordinator being accessed via the virtual resource locator provided to the client by the content management system, dynamically generate a manifest file based at least in part on: playback quality experienced by one or more clients determined to be correlated with the client, and the plurality of content delivery networks encoded in the virtual resource locator; and
send, to the client, the manifest file dynamically generated based at least in part on: the playback quality experienced by the one or more clients determined to be correlated with the client, and the plurality of content delivery networks encoded in the virtual resource locator, wherein the client is configured to obtain the requested content according to the dynamically generated manifest file; and

a memory coupled to the one or more processors and configured to provide the one or more processors with instructions.

2. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of a protocol type associated with the requested content.

3. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an identifier associated with the content management system.

4. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of one or more bitrates at which the content is stored.

5. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes a name of the content being requested by the client.

6. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes a type of the content being requested by the client.

7. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of a type of a device associated with the client.

8. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of an access connection associated with a device associated with the client.

9. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of a digital rights management technology used for the requested content.

10. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of an operating system of a device associated with the client.

11. The system recited in claim 10 , wherein the information encoded in the virtual resource locator includes an indication of a version of the operating system.

12. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of a location of the content distribution coordinator.

13. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes a security token that was previously generated by the content distribution coordinator and passed to the content management system.

14. The system recited in claim 13 , wherein the one or more processors are further configured to validate the security token.

15. The system recited in claim 1 , wherein the information encoded in the virtual resource locator includes an indication of a firmware version of a device associated with the client.

16. A method, comprising:
receiving, at a content distribution coordinator, a manifest request from a client requesting content, wherein the client is configured to access the content distribution coordinator via a virtual resource locator provided to the client by a content management system, wherein the content management system provided the virtual resource locator to the client in response to the client having made a request to the content management system for content, and wherein the virtual resource locator provided to the client by the content management system encodes information including a plurality of content delivery networks at which the requested content is stored;
in response to the content distribution coordinator being accessed via the virtual resource locator provided to the client by the content management system, dynamically generating, using one or more processors, a manifest file based at least in part on: playback quality experienced by one or more clients determined to be correlated with the client, and the plurality of content delivery networks encoded in the virtual resource locator; and
sending, to the client, the manifest file dynamically generated based at least in part on: the playback quality experienced by the one or more clients determined to be correlated with the client, and the plurality of content delivery networks encoded in the virtual resource locator, wherein the client is configured to obtain the requested content according to the dynamically generated manifest file.

17. A computer program product embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
receiving, at a content distribution coordinator, a manifest request from a client requesting content, wherein the client is configured to access the content distribution coordinator via a virtual resource locator provided to the client by a content management system, wherein the content management system provided the virtual resource locator to the client in response to the client having made a request to the content management system for content, and wherein the virtual resource locator provided to the client by the content management system encodes information including a plurality of content delivery networks at which the requested content is stored;
in response to the content distribution coordinator being accessed via the virtual resource locator provided to the client by the content management system, dynamically generating a manifest file based at least in part on: playback quality experienced by one or more clients determined to be correlated with the client, and the plurality of content delivery networks encoded in the virtual resource locator; and
sending, to the client, the manifest file dynamically generated based at least in part on: the playback quality experienced by the one or more clients determined to be correlated with the client, and the plurality of content delivery networks encoded in the virtual resource locator, wherein the client is configured to obtain the requested content according to the dynamically generated manifest file.
