20110276585SYSTEMS AND METHODS FOR ACCESSING CONTENT USING AN INTERNET CONTENT GUIDE - Systems and methods for providing Internet Content Guides (ICG) on playback devices that can be used to access content via the Internet from a plurality of sources using a remote database containing navigation hierarchy definitions for specific device models and/or device instances are described, where content metadata included in the remote database is collected by a remote server from the plurality of sources. One embodiment of the invention includes a metacenter configured to retrieve content metadata from feeds on a plurality of remote servers describing content accessible via the remote servers and to use the content metadata retrieved from the feeds to update a content metadata database, and a plurality of playback devices configured to communicate with the metacenter and access content via the Internet. In addition, the content metadata database defines a plurality of navigation hierarchies for different playback devices, where each navigation hierarchy includes category information and content information, each playback device is configured to obtain a navigation hierarchy appropriate to the playback device from the metacenter, where the navigation hierarchy obtained by the playback device only includes category and content information that the playback device is authorized to access and is capable of playing back, and the playback devices are configured to generate an Internet content guide using the navigation hierarchy obtained from the metacenter.11-10-2011
20110258623REAL TIME FLASH BASED USER INTERFACE FOR MEDIA PLAYBACK DEVICE - Common clients for consumer electronics devices that include natively implemented virtual machines are described. One embodiment of the invention includes audio and video decoders, a natively implemented host process, a natively implemented virtual machine, a common client including natively implemented processes configured to coordinate playback of audio and video using the playback device's audio and video decoders, a VM framework configured to execute within the virtual machine and to enable scripts executing within the virtual machine to initiate playback of audio and video using the natively implemented processes, and a user interface implemented as a script configured to be executed within the virtual machine.10-20-2011
20110135090ELEMENTARY BITSTREAM CRYPTOGRAPHIC MATERIAL TRANSPORT SYSTEMS AND METHODS - Systems and methods for providing multimedia content from one process or component to another process or component over an unsecured connection are provided. One embodiment includes obtaining the cryptographic information, extracting the at least partially encrypted video data from the container file to create an elementary bitstream, enciphering the cryptographic information, inserting the cryptographic information in the elementary bitstream, providing the elementary bitstream to a video decoder, extracting the cryptographic information from the elementary bitstream at the video decoder, deciphering the cryptographic information, decrypting the elementary bitstream with the cryptographic information and decoding the elementary bitstream for rendering on a display device using the video decoder.06-09-2011
20110129202SYSTEM AND METHOD FOR DETERMINING BIT STREAM COMPATIBILITY - Systems and methods for determining whether a decoder can playback compressed video identified as being encoded with an operating profile and/or level unsupported by the decoder are shown. Systems and methods are described for playing back video encoded as an elementary bitstream, where the elementary bitstream has a specified encoding profile and satisfies at least one playback condition. A number of embodiments include a decoder that is incapable of playing back video encoded in accordance with the specified encoding profile. In addition, the decoder is configured to locate the specified encoding profile within the elementary bitstream. The decoder is also configured to determine whether the elementary bitstream satisfies the at least one playback condition in response to the location of the specified encoding profile within the elementary bitstream. Furthermore, the decoder is configured to commence playback of the elementary bitstream based upon the determination that the at least one playback condition is satisfied.06-02-2011
20110099225VIDEO DISTRIBUTION SYSTEM INCLUDING PROGRESSIVE PLAYBACK - A receiver driven approach for playback of remote content is described. One embodiment includes obtaining information concerning the content of the media file from the remote server, identifying a starting location within the media sequence, identifying byte ranges of the media file corresponding to media required to play the media sequence from the starting location, requesting the byte ranges required to play the media sequence from the starting location, buffering received bytes of information pending commencement of playback, playing back the buffered bytes of information, receiving a user instruction, identifying byte ranges of the media file corresponding to media required to play the media sequence in accordance with the user instruction, flushing previous byte range requests, and requesting the byte ranges required to play the media in accordance with the user instruction.04-28-2011
