Abstract

Methods for preventing ad stripping from ad-supported digital content include removing part of the content, and using a digital rights management (DRM) proxy server to provide links to any removed content part and to ads to be inserted in the content to a player who plays the content with the ads. The DRM proxy server ensures that the player cannot distinguish between removed content parts and the ads. A system enabling the method includes in addition to the DRM server and player an encoder used to remove at least one part from the content, encode the remaining content and the removed part and supplying links to each removed part to the DRM proxy server. The system further includes an ad server used to provide links to ads to the DRM proxy server.

Claims

1. A method for preventing ad stripping from ad-supported digital content comprising the steps of:

at a digital rights management (DRM) proxy server;

a) receiving a link to each missing part related to a given content;

b) receiving, from a player, a call for a link to each missing part related to the given content and a call for a link to each ad that needs to be shown in the given content;

c) receiving the link to each ad; and

d) passing the link to each ad and the link to each missing part to the player, thereby enabling the player to play the given content in a complete form including missing parts and ads.

2. The method of claim 1, wherein the step of passing the link to each ad and the link to each missing part to the player includes masking any difference between each ad and each missing part.

3. The method of claim 1, wherein the step of receiving a call for a link to each missing part includes receiving a call for each missing part itself and wherein the step of passing the link to each missing part includes passing each missing part to the player.

4. The method of claim 1, wherein the step of receiving a call for a link to ad includes receiving a call for ad itself and wherein the step of passing the link to each ad includes passing each ad to the player.

5. The method of claim 1, wherein the player is selected from the group consisting of a video player, an audio player, a Web browser, a multimedia player, a dedicated software application which includes ads and a computer game which includes ads.

6. The method of claim 1, wherein the step of receiving the link to each ad includes receiving the link to each ad from an ad server.

7. The method of claim 1, wherein the given content is streamed.

8. A method for preventing ad stripping from ad-supported digital content, wherein a given content is divided and encoded into a main part and at least one missing part in a given format to a player, the method comprising the steps of:

a) providing a digital rights management (DRM) proxy server; and

b) in response to calls from the player for ads and missing parts, using the DRM proxy server to provide the player a respective link to each ad and each missing part such that the links to the ads and the missing parts are indistinguishable to the player;

whereby the player receives the main part and the links to ads and missing parts and plays the given content in a complete form including missing parts and ads.

9. The method of claim 8, wherein the step of using the DRM proxy server to provide the player a respective link to each ad and each missing part such that the links to the ads and the missing parts are indistinguishable to the player includes using the DRM proxy server to provide the player each ad and each missing part such that the ads and the missing parts are indistinguishable to the player.

10. The method of claim 8, wherein the step of using the DRM proxy server to provide the player a respective link to each ad and each missing part such that the links to the ads and the missing parts are indistinguishable to the player is preceded by the step of, by the DRM proxy server, receiving a link to each missing part of the given content.

11. The method of claim 9, wherein using the DRM proxy server to provide the player each ad and each missing part such that the ads and the missing parts are indistinguishable to the player is preceded by the step of, by the DRM proxy server, receiving the respective missing parts of the given content.

12. The method of claim 10, wherein the receiving a link to each missing part of the given content includes receiving a meta-file related to the given content, which meta-file includes a link to each missing parts.

13. The method of claim 9, wherein the using the DRM proxy server to provide the player each ad and each missing part such that the ads and the missing parts are indistinguishable to the player includes providing an ad received from an ad server.

14. The method of claim 8, wherein the player is selected from the group consisting of a video player, an audio player, a Web browser, a multimedia player, a dedicated software application which includes ads and a computer game which includes ads.

15. The method of claim 8, wherein the given content is streamed.

16. A system for preventing ad stripping from ad-supported digital content played by a player, comprising:

a) an encoder used to split a given content into a main part and at least one missing part and to provide the main part and each missing part in a given format to the player; and

b) a digital rights management (DRM) proxy server in operative communication with the player, with the encoder and with an ad server and used for rendering calls for ads and missing parts indistinguishable to the player.

17. The system of claim 16, further comprising a content server for storing the main part and each missing part.

18. The system of claim 16, wherein the DRM proxy server is used for rendering ads and missing parts indistinguishable to the player.
