Abstract

A method, performed by a video provisioning system, may include receiving a request for a first digital rights management (DRM) token, associated with a video asset purchased via the video provisioning system, from a browser application associated with a user device and providing the first DRM token to the browser application. The method may further include receiving a license authorization request to issue a DRM license for the video asset, where the license authorization request is received from a license server, where the DRM license is to be used by the user device to decrypt the video asset, and where the license authorization request includes a second DRM token; determining whether the second DRM token matches the first DRM token; and authorizing the license server to issue the DRM license for the video asset, when the second DRM token matches the first DRM token.

Claims

1. A method comprising:

receiving, by a video provisioning system, a request for a first digital rights management token, associated with a video asset purchased via the video provisioning system, from a browser application associated with a user device;

determining, by the video provisioning system, whether the second digital rights management token matches the first digital rights management token; and

authorizing, by the video provisioning system, the license server to issue the digital rights management license for the video asset, when the second digital rights management token matches the first digital rights management token.

2. The method of claim 1, further comprising:

receiving a request for a stream of the video asset;

determining whether the user device is associated with an account that is associated with a quantity of streams of video assets less than a particular quantity; and

authorizing the steam of the video asset, when the quantity of streams of video assets is less than the particular quantity.

3. The method of claim 1, where the video asset is encrypted using a first digital rights management scheme, where the digital rights management license is associated with a second digital rights management scheme, and where the first digital rights management scheme is different from the second digital rights management scheme.

4. The method of claim 1, where the first digital rights management scheme includes a Windows Media Digital Rights Management scheme and where the second digital rights management scheme includes a PlayReady Digital Rights Management scheme.

5. The method of claim 1, further comprising:

receiving a username from the user device;

authenticating the user device using the received username; and

where providing the first digital rights management token to the user device is performed in response to authenticating the user device.

6. The method of claim 1, where the first digital rights management token expires after a particular length of time.

7. The method of claim 1, further comprising:

retrieving a bookmark, associated with the video asset, from a video provisioning system profile associated with the user device;

converting the bookmark to a range header value; and

providing the range header value to the browser application.

8. The method of claim 1, further comprising:

receiving a range header value, associated with the video asset, from the browser application;

converting the range header value to a bookmark; and

storing the bookmark in a video provisioning system profile associated with the user device.

9. A video provisioning system comprising:

one or more server devices to;

receive a request for a first digital rights management token, associated with a video asset purchased via the video provisioning system, from a browser application associated with a user device;

provide the first digital rights management token to the browser application;

receive a license request from the browser application for a digital rights management license to decrypt the video asset, where the license request includes a second digital rights management token;

determine whether the second digital rights management token matches the first digital rights management token;

authorize the digital rights management license for the video asset to be issued, when the second digital rights management token matches the first digital rights management token; and

provide the digital rights management license to the browser application, in response to receiving the authorization.

10. The video provisioning system of claim 9, further comprising:

a catalog server to;

store a key for the video asset, where the key is associated with a first digital rights management scheme used to encrypt the video asset; and

where the one or more server devices are further to;

obtain the key from the catalog server; and

generate the digital rights management license using the obtained key as a license seed, in response to receiving the authorization from the application server, where the digital rights management license is associated with a second digital rights management scheme, and where the first digital rights management scheme is different from the second digital rights management scheme.
