Abstract

Enforcing rendering of advertisements and other predetermined media content in connection with playback of download selected media content. Playback of selected media content is made conditional on acquistion of a locally cached playback token in response to playback of the predetermined content. The playback token may be implemented as a digital rights management (DRM) license acquired from a local cache in response to playback of the predetermined content. Another aspect involves a downloading ads or other predetermined content with associated playback tokens in a local cache.

Claims

1. A method of enforcing rendering of predetermined media content in connection with rendering selected media content, said method comprising:

receiving a request for selected media content to be rendered to a user via a computing device coupled to a network;

downloading the selected media content to the computing device via the network in response to the request;

rendering predetermined media content to the user via the computing device;

receiving at least one token associated with the predetermined media content in response to the rendering of the predetermined media content, said token being stored in a cache at the computing device;

permitting the selected media content to be rendered to the user via the computing device in response to receiving the token from the cache.

2. The method of claim 1, further comprising downloading the predetermined media content to the computing device via the network and storing the downloaded predetermined media content and the token associated therewith in the cache.

3. The method of claim 1, further comprising encrypting the selected media content before downloading the selected media content.

4. The method of claim 3, wherein permitting the selected media content to be rendered comprises decrypting the encrypted selected media in response to receiving the token from the cache.

5. The method of claim 1, further comprising specifying, by a content insertion engine, the predetermined media content to be rendered in connection with the selected media content.

6. The method of claim 5, further comprising raising an event to the content insertion engine in response to receiving the request for the selected media content, said event triggering the rendering of the predetermined media content from the cache.

7. The method of claim 1, wherein the selected media content comprises a video program and the predetermined media content comprises targeted advertising associated with the video program.

8. The method of claim 1, further comprising:

rendering the selected media content to the user via the computing device;

interrupting the rendering of the selected media content;

rendering additional predetermined media content to the user via the computing device;

receiving another token from the cache in response to the rendering of the additional predetermined media content, said other token being associated with the additional predetermined media content; and

permitting the selected media content to resume rendering to the user via the computing device in response to receiving the other token from the cache.

9. The method of claim 1, wherein the token comprises a DRM license.

10. A method of enforcing rendering of predetermined media content in connection with rendering selected media content to a user, said method comprising:

downloading predetermined media content to a computing device via a network coupled therewith;

storing the downloaded predetermined media content in a cache at the computing device;

downloading selected media content to the computing device via the network in response to a request from the user for the selected media content to be rendered via the computing device, said selected media content being encrypted;

rendering the predetermined media content to the user via the computing device;

acquiring a token in response to the rendering of the predetermined media content; and

decrypting the selected media content with the token to permit the selected media content to be rendered to the user via the computing device.

11. The method of claim 10, further comprising storing the token associated with the downloaded predetermined media content in the cache.

12. The method of claim 10, further comprising raising an event to the content insertion engine in response to receiving the request for the selected media content, said event triggering the rendering of the predetermined media content from the cache.

13. The method of claim 10, wherein the selected media content comprises a video program and the predetermined media content comprises targeted advertising associated with the video program.

14. The method of claim 10, further comprising:

rendering the selected media content to the user via the computing device;

interrupting the rendering of the selected media content;

rendering additional predetermined media content to the user via the computing device;

acquiring another token in response to the rendering of the additional predetermined media content, said other token being associated with the additional predetermined media content; and

permitting the selected media content to resume rendering to the user via the computing device in response to the other token.

15. The method of claim 10, wherein the token comprises a DRM license.

16. A media player system for rendering encrypted media content to a user, said system comprising:

a playback engine for rendering media content to a user;

a cache associated with the playback engine, said cache storing predetermined media content and at least one token associated therewith;

a content insertion engine for specifying predetermined media content to be rendered to the user via the playback engine, said content insertion engine acquiring the token associated with the predetermined media content in response to the playback engine rendering the predetermined media content;

a playback enforcer, receiving and responsive to the token acquired by the content insertion engine, for decrypting the encrypted media content and permitting the playback engine to render the encrypted media content to the user.

17. The media player system of claim 16, further comprising a local computing device for executing the playback engine, said local computing device being coupled to a network, and wherein the encrypted media content, the predetermined media content, and the token are downloaded to the local computing device via the network.

18. The media player system of claim 16, wherein the encrypted media content comprises a video program and the predetermined media content comprises targeted advertising associated with the video program.

19. The media player system of claim 16, wherein the playback engine is responsive to the content insertion engine for interrupting the rendering of the encrypted media content to render additional predetermined media content to the user, said content insertion engine acquiring another token from the cache in response to the rendering of the additional predetermined media content, and wherein the playback enforcer is responsive to the other token to permit the playback engine to resume rendering the encrypted media content.

20. The media player system of claim 16, wherein the playback enforcer comprises a DRM system and wherein the token comprises a DRM license.
