A method, apparatus, and manufacture for instantiating a browser plugin is provided. A client web browser of a client is employed to instantiate a browser plugin for the client web browser. Next, the client web browser is employed to obtain a reference to the browser plugin. Then, a command is given to the browser plugin via the reference to the browser plugin. The browser plugin is used by the client web browser rather than the web page.
대표청구항▼
1. A method, comprising: employing a client web browser of a client to instantiate, responsive to an action initiated by a web page received by the web browser, a browser plugin for the client web browser, the browser plugin being instantiated by the client web browser based on one or more elements
1. A method, comprising: employing a client web browser of a client to instantiate, responsive to an action initiated by a web page received by the web browser, a browser plugin for the client web browser, the browser plugin being instantiated by the client web browser based on one or more elements in a local resource other than from within the web page;employing the client web browser to obtain a reference to the browser plugin the reference to the browser plugin being inaccessible from the web page; andproviding a command to the browser plugin via the reference to the browser plugin. 2. The method of claim 1, wherein the reference to the browser plugin includes at least one of a pointer to the browser plugin, a name of the browser plugin, or an identification to find access the browser plugin. 3. The method of claim 1, wherein the command to the browser plugin is a command associated with obtaining a key for decrypting encrypted media content. 4. The method of claim 1, further comprising: registering the browser plugin with the client web browser. 5. The method of claim 1, wherein the browser plugin is sandboxed. 6. The method of claim 1, wherein the browser plugin is an in-page plugin that is invoked by Hypertext Markup Language Protocol. 7. The method of claim 1, further comprising: giving another command to the browser plugin via the reference to the browser plugin. 8. The method of claim 1, wherein instantiating the browser plugin is accomplished by injecting, based on the action initiated from within the web page, the one or more elements into a shadow document object model. 9. The method of claim 1, wherein instantiating the browser plugin is accomplished by injecting elements into the web page. 10. The method of claim 1, wherein instantiating the browser plugin is accomplished by injecting, based on the action initiated from within the web page, the one or more elements into a hidden web page that is separate from the web page. 11. The method of claim 1, wherein instantiating the browser plugin is accomplished by injecting, based on the action initiated from within the web page, the one or more elements into a hidden frame that is separate from the web page. 12. The method of claim 1, wherein the browser plugin is a content decryption module. 13. The method of claim A, further comprising: employing the client web browser to load a web application;employing the web application to get a license for encrypted media content;employing the web application to instruct a media stack of the client web browser to play the encrypted media content;sending the license from the web application to the media stack;sending the license from the media stack to the content decryption module, wherein the media stack and the content decryption module are distinct binaries from each other; andsending encrypted data from the media stack to the content decryption module, wherein the encrypted data includes at least a portion of the encrypted media content, and wherein the command to the browser plugin is a command to provide decrypted data by decrypting the encrypted data. 14. The method of claim 1, wherein instantiating the browser plugin includes creating a sub-tree of a main document object model, and wherein the sub-tree is inaccessible from the document object model. 15. The method of claim 14, further comprising destroying the sub-tree. 16. The method of claim 14, wherein the sub-tree includes a markup tag such that, when rendered, causes the browser plugin to be instantiated. 17. The method of claim 16, wherein instantiating the browser plugin further includes rendering the sub-tree. 18. A client device, comprising: a memory component for storing data; anda processing component that is configured to execute data that enables actions, including: employing a client web browser of the client device to instantiate, responsive to an action initiated by a web rage received by the web browser, a browser plugin for the client web browser, the browser plugin being instantiated by the client web browser based on one or more elements in a local resource other than from within the web page;employing the client web browser to obtain a reference to the browser plugin, the reference to the browser plugin being inaccessible from the web page; andproviding a command to the browser plugin via the reference to the browser plugin. 19. A manufacture, including a tangible processor-readable storage medium having processor-executable code encoded therein, which when executed by one or more processors, enables actions, comprising: employing a client web browser of a client to instantiate, responsive to an action initiated by a web page received by the web browser, a browser plugin for the client web browser, the browser plugin being instantiated by the client web browser, not the web page, based on one or more elements in a local resource that is hidden from the web page;employing the client web browser to obtain a reference to the browser plugin the reference to the browser plugin being inaccessible from the web page; andproviding a command to the browser plugin via the reference to the browser plugin.
