Abstract: Techniques are described for reducing time to decrypt a next encrypted frame in a content stream by optimizing a license/key acquisition process. When requesting content, a key identifier and/or license identifier may be included within a webpage using a link, script, or similar access point. When a client device sends a request for content, the loading of the webpage within the client device includes the embedded key identifier. Access to the key/license identifier at the client device then may initiate a key/license acquisition process by the client device. The key/license may be obtained from a key management device in parallel with, or prior to, downloading of at least a portion of the content stream.

Abstract: A method, apparatus, and manufacture for content protection for protecting some objects is provided. A content protection operation or license operation is performed for at least one media object of a web application. Some or all of the objects are then marked as protected. When an operation is performed that accesses a protected object, a user agent determines whether to deny the operation, to allow the operation and mark data exported by the operation and objects storing the exported data as protected objects, or to allow the operation and not mark data exported by the operation and objects storing the exported data as protected objects.

Abstract: 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.
