Abstract

Described are methods and apparatuses, including computer program products, for personalizing video content. A server receives a request for a digital video stream from a client device and generates a first set of personalized frames to be inserted into the requested digital video stream. The server combines the first set of personalized frames and the requested digital video stream to generate a personalized video stream and transmits the personalized video stream to a downstream device. The downstream device generates a second set of personalized frames to be inserted into the personalized video stream and combines the second set of personalized frames and the personalized video stream to generate an updated personalized video stream for transmission to the client device.

First claim

What is claimed is:

1. A computerized method for personalizing video content, the method comprising
receiving, by a server computing device, a request for a digital video stream from a client device, the request including authentication data associated with a user of the client device;
generating, by the server computing device, a first set of personalized frames to be inserted into the requested digital video stream, wherein the personalized frames include content data specific to the user and one or more keys corresponding to content data common to a plurality of users;
combining, by the server computing device, the first set of personalized frames and the requested digital video stream by extracting one or more frames from the requested digital video stream and replacing the extracted frames with one or more frames from the first set of personalized frames to generate a personalized video stream;
transmitting, by the server computing device, the personalized video stream to a downstream device;
generating, by the downstream device, a second set of personalized frames to be inserted into the personalized video stream, wherein the second set of personalized frames include content data corresponding to the one or more keys;
combining, by the downstream device, the second set of personalized frames and the personalized video stream by extracting one or more frames from the personalized video stream and replacing the extracted frames with one or more frames from the second set of personalized frames to generate an updated personalized video stream; and
transmitting, by the downstream device, the updated personalized video stream to the client device.

2. The method of claim 1 , further comprising encrypting, by the server computing device, the content data specific to the user using the authentication data.

3. The method of claim 1 , further comprising encrypting, by the downstream device, the content data corresponding to the one or more keys using the authentication data.

4. The method of claim 1 , wherein the downstream device is a cable head-end, a router, a modem, a content cache, or a cell tower.

5. The method of claim 1 , wherein the frames containing the one or more keys are fewer than the frames containing the content data specific to the user.

6. The method of claim 1 , further comprising determining, by the server computing device, the content data common to a plurality of users by analyzing a user profile associated with each of the plurality of users.

7. The method of claim 1 , further comprising determining, by the server computing device, the content data common to a plurality of users by analyzing a history of content data provided to the plurality of users.

8. The method of claim 1 , wherein the step of generating a second set of personalized frames to be inserted into the personalized video stream comprises
extracting, by the downstream device, the one or more keys from the personalized video stream;
retrieving, by the downstream device, content data corresponding to the one or more keys; and
generating, by the downstream device, the second set of personalized frames using the content data corresponding to the one or more keys.

9. The method of claim 8 , wherein the downstream device retrieves the content data corresponding to the one or more keys from a local storage device.

10. The method of claim 1 , wherein the downstream device is logically coupled between the server computing device and the client device so that data transmitted from the server computing device travels through the downstream device before reaching the client device.

11. A system for personalizing video content, the system comprising
a server computing device coupled to a downstream device and a client device, the server computing device configured to
receive a request for a digital video stream from the client device, the request including authentication data associated with a user of the client device;
generate a first set of personalized frames to be inserted into the requested digital video stream, wherein the personalized frames include content data specific to the user and one or more keys corresponding to content data common to a plurality of users;
combine the first set of personalized frames and the requested digital video stream by extracting one or more frames from the requested digital video stream and replacing the extracted frames with one or more frames from the first set of personalized frames to generate a personalized video stream; and
transmit the personalized video stream to the downstream device;

the downstream device configured to
generate a second set of personalized frames to be inserted into the personalized video stream, wherein the second set of personalized frames include content data corresponding to the one or more keys;
combine the second set of personalized frames and the personalized video stream by extracting one or more frames from the personalized video stream and replacing the extracted frames with one or more frames from the second set of personalized frames to generate an updated personalized video stream; and
transmit the updated personalized video stream to the client device.

12. The system of claim 11 , wherein the server computing device is configured to encrypt the content data specific to the user using the authentication data.

13. The system of claim 11 , wherein the downstream device is configured to encrypt the content data corresponding to the one or more keys using the authentication data.

14. The system of claim 11 , wherein the downstream device is a cable head-end, a router, a modem, a content cache, or a cell tower.

15. The system of claim 11 , wherein the frames containing the one or more keys are fewer than the frames containing the content data specific to the user.

16. The system of claim 11 , wherein the server computing device is configured to determine the content data common to a plurality of users by analyzing a user profile associated with each of the plurality of users.

17. The system of claim 11 , wherein the server computing device is configured to determine the content data common to a plurality of users by analyzing a history of content data provided to the plurality of users.

18. The system of claim 11 , wherein generating a second set of personalized frames to be inserted into the personalized video stream comprises
extracting the one or more keys from the personalized video stream;
retrieving content data corresponding to the one or more keys; and
generating the second set of personalized frames using the content data corresponding to the one or more keys.

19. The system of claim 18 , wherein the downstream device retrieves the content data corresponding to the one or more keys from a local storage device.

20. The system of claim 11 , wherein the downstream device is logically coupled between the server computing device and the client device so that data transmitted from the server computing device travels through the downstream device before reaching the client device.

21. A computer program product, tangibly embodied in a non-transitory computer readable storage device, for personalizing video content, the computer program product including instructions operable to cause a server computing device, that is coupled to a downstream device and a client device, to
receive a request for a digital video stream from the client device, the request including authentication data associated with a user of the client device;
