Thursdays the PTO publishes new pending patent applications. Both of today's Spotlight Applications concern aspects of digital rights management. Assigned to Netflix, the first application discloses techniques for the speculative pre-authorization of encrypted data streams. Assigned to Condel International, the second application discloses techniques for protecting program file content using digital rights management (DRM).
20140052873, "Speculative pre-authorization of encrypted data streams," assigned to Netflix.
Techniques are disclosed for improving user experience of multimedia streaming over computer networks. For example, a method for presenting multimedia content may generally include receiving a request to stream a media title. In response to the request, unencrypted content for the media title is streamed to a client. While streaming the unencrypted content, a digital rights management (DRM) license to access encrypted content for the media title is requested. After receiving the DRM license, the client switches from streaming the unencrypted content for the media title to streaming encrypted content for the media title. The switching from streaming the unencrypted content to streaming the encrypted content does not interrupt playback of the media title.
20140059708, "Apparatuses and methods for protecting program file content using digital rights management (DRM)," assigned to Condel International Technologies Inc.
An electronic device for protecting program file content using Digital Rights Management (DRM) is provided with a DRM agent module, a plug-in, and a web browser module. The DRM agent module is configured to process DRM-protected content associated with a program file. The plug-in is configured to enable execution of the program file. The web browser module is installed with the DRM agent module, and is configured to activate the processing of the DRM-protected content of the DRM agent module to obtain the program file portion-by-portion, and use the plug-in to execute the program file with the obtained portions.
