摘要： A sequence of content keys are shared between a receiver of pieces of digital content and a computing device upon which the content is to be rendered. The receiver encrypts each piece of content according to a corresponding content key in the sequence and forwards the encrypted content to the computing device and the computing device decrypts the encrypted content according to the corresponding content key. The receiver initially transmits to the computing device an initialization digital license with an initial content key (CK0) therein. Each of the receiver and the computing device derive a new content key (CKx) in the sequence from the initial content key (CK(0)) in the sequence on an as-needed basis and in a coordinated fashion. The initialization license is required only once for the sequence of content keys, and the receiver need not explicitly communicate (CKx) to the computing device for each piece of content.

摘要： A media server in a home entertainment network coordinates with a media player connected with the network to provide a media presentation with a combined user interface (UI) on an attached display device. Media content is sourced locally on a networked media player. The media player extracts metadata related to the media content and transmits the metadata to the media server. The media server creates the UI to include components related to the media content rendered by the media player. The media server then transmits the UI to the media player for combination with the rendered media content for a composite output to a presentation device. The media server may further develop and transmit compositing instructions and additional media content to the media player for inclusion in the composite output.

摘要： The scaling of a user interface according to network or device limitations is disclosed. One embodiment provides a method of scaling a user interface, comprising sending a user interface over a network to a networked device, detecting a performance limitation of the user interface in at least one of the network or the networked device, and scaling a parameter of the user interface in response to the detected limitation to improve the performance of the user interface. In this manner, a user interface may be scaled in response to limitations on performance and end-user experience can be improved.

摘要： A host computer manages and processes multiple requests for transmission of media content to other devices within a network. Hardware or software-driven media processing units format media content for streaming to the network devices. A policy engine manages processing constraints of the media processing units to determine the best combination of transrate/transcode processes to provide the highest quality transmissions without overloading the processing capacity of the host computer. The policy engine also considers available network bandwidth when determining transformation instructions for the media processing units. The policy engine identifies target formats, bit rates, and image resolutions for output for each media stream or for storage for later transmission and instructs the media processing units to transrate and/or transcode the media content appropriately to meet the demand.

摘要： A media server in the home entertainment network allows a media rendering devices to act as a digital media receiver. The media server enables trick mode functions such as scan forward or reverse, slow motion, pause, and seek on rendering devices with capabilities limited to 1× playback. The media server receives commands from user input at the rendering device transmitted over the network to the media server. The media server manipulates the media stream before the transmission over the network by deleting or adding frames to the media stream as necessary to emulate the desired playback functions and replacing frame timestamps to create a media stream that appears to the media rendering device as a sequential 1× stream. The transmitted media stream may not contain all of the media content stored in the corresponding media file on the media server, thus avoiding limitations on the download bandwidth and local client storage.

摘要： A media server in a home entertainment network coordinates with a media receiver connected with the network to provide a media representation with a combined user interface on an attached display device. The media server receives compositing information from the media receiver over the network regarding the placemement of UI components generated by the media receiver. In response, the media server may adjust the positioning of graphics, media control information, metadata, media presentation windows, and other UI components for presentation by the media receiver such that the UI components generated by the media server do not interfere with the UI generated by the media receiver when rendered to the display device. Alternately, the media receiver may adjust the position of UI components such that the UI components generated by the media receiver do not interfere with the UI generated by the media server upon presentation.

摘要： Transrate/transcode functionality of media processing units in devices distributed within a networked media system are harnessed to enable media streaming to devices across networks while overcoming insufficient bandwidth to transmit the source content or while providing reformatted media to devices that do not support the source format. A policy engine may reallocate media processing resources for greater efficiency. The policy engine may further schedule time-slicing of media segments in available hardware and software-based codecs. Time-slicing may be used to transformatively process one or more media streams across potentially multiple media processing units connected within a network. The media streams are divided into independently processable segments based upon knowledge of underlying media formats. Processing requirements and a priority processing order may be determined for and assigned to each independently processable segment. The segments may be scheduled for delivery to the media processing units based upon the assigned priority and processing requirements.
