Abstract: Systems and methods are provided in which eyewear with time shared viewing is capable of supporting delivery of differing content to multiple viewers/users. The content that is delivered to each viewer includes a respective frame sequence that is displayed on a screen. The frame sequences are mixed when they are displayed on the screen. A lens assembly may be used by each viewer to view the frame sequence that is delivered to that viewer. For instance, a first lens assembly may pass a first frame sequence but not frame sequences other than the first frame sequence. A second lens assembly may pass a second frame sequence but not frame sequences other than the second frame sequence, and so on. The content that is delivered to a viewer may depend on a maturity of the viewer (e.g., whether the viewer's maturity is less than a maturity threshold).

Abstract: A clock frequency is controlled by determining a cumulative duty cycle according to a ratio of a cumulative time, during an interval, that the clock frequency has a frequency greater than or equal to a design frequency threshold value to a duration of the interval. A frequency of the clock frequency is controlled to be a first frequency value when the cumulative duty cycle is less than a first duty cycle threshold; and controlled to be a second frequency value substantially less than the first frequency value when the cumulative duty cycle is greater than a second duty cycle threshold. The second duty cycle threshold is greater than or equal to the first duty cycle threshold.

Abstract: A media playback device may be operable to determine whether replacement media content corresponding to at least a portion of a received broadcast media stream is available during reception of the broadcast media stream from one or more broadcast sources. At least some of the replacement media content may then be retrieved when personal video recording (PVR) operations are requested during play of the received broadcast media stream, to enable seamless performance of the requested PVR operations using at least a portion of the retrieved replacement media content. Exemplary PVR operations may comprise pausing, fast forwarding, and/or rewinding. The replacement media content may be retrieved from a plurality of local and/or remote replacement servers. Availability of replacement media content, from remote replacement servers, may be determined based on programming data in said broadcast media stream, routing information provided by a broadcast source, and/or by inquiry via one or more cataloguing servers.

Abstract: Systems and methods for providing capture functionality according to a security policy are provided. A request to capture content is received from a requesting application at a capture controller. The request is evaluated based on the security policy of the capture controller. Based on the evaluation, a determination is made as to whether the request is to be granted completely, denied, or granted subject to a constraint. Capture of the requested content is initiated via capture hardware or software if the request is granted completely or granted subject to the constraint.

Abstract: A method and system are provided in which a processor may perform fast source switching and/or automatic source switching by keeping active the signals from multiple sources. The processor may determine which received video signals are locked-in within a front-end portion of the processor. A video signal may be locked-in when a demodulator is locked to a carrier in the video signal or when a decoder is programmed to decode the video signal. During operation, the processor may switch from processing a current video signal to processing a video signal selected from those determined to be locked-in. The processor may maintain active a portion of a back-end portion of the processor to handle the switch from the current video signal to the selected video signal. The processor may switch to process between video signals when a predetermined content and/or metadata is detected within one of the video signals.

Abstract: A method and system are provided in which a video channel is selected from multiple video channels in a video processor. A picture quality profile associated with a content of the selected video channel is received by the video processor to modify a value of one or more picture quality control parameters utilized by the video processor that are mapped to a user level setting. Metadata associated with the content of the selected video channel may be determined and communicated to a server. The server may utilize the metadata to determine a picture quality profile for the video processor. In some instances, environmental conditions associated with a television or display device may be measured and communicated to the server to determine the picture quality profile. For example, the measured environmental conditions may comprise one or more of an ambient light, a sound, a motion, and a temperature measurement.

Abstract: A method and system are provided in which a video image may be scaled from a first to a second video format. The scaling may be a non-uniform scaling such as an anamorphic scaling. When panning associated with the scaled video image is detected, one or more end portions of a current frame of the scaled video image may be adjusted, the adjustment being based on one or more frames of the scaled video image that are previous to the current frame. The adjustment may result from combining information from the corresponding end portion of previous frames with the information of the current frame. One or more end portions that are opposite to the ones adjusted may also be adjusted based on one or more frames of the scaled video image that are subsequent to the current frame. The panning detected may be horizontal, vertical, or a combination thereof.

Abstract: Embodiments of the present invention significantly decrease the processing requirements as well as the cost of digital television receivers. In an embodiment, processing requirements of both hardware and software components in digital television receivers are lowered by generating the channel map without regard to channel map information present in a Virtual Channel Table (VCT). In another embodiment, significant recurring portions of an ATSC signal can be neglected with no processing power, cost, and time spent thereon. In another embodiment, processing typically used to process channel map information contained in the VCT portion of the ATSC signal is freed and may instead be used to process other information, thereby enabling further enhancements and features in digital television services.

Abstract: A three-dimensional (3D) video device may provide an interactive 3D user interface (UI). This may be achieved by generating 3D video data representative of the 3D user interface; displaying the 3D user interface using the generated 3D video data such that the displayed 3D user interface may create a 3D perception within the proximity of a user; tracking spatial and/or temporal movement of the user relative to the displayed 3D user interface to determine user input and/or feedback; and controlling operation of the 3D video processing device based on the tracking. The generated 3D video data may comprise stereoscopic left view and right view sequences, and it may be generated based on determination of a location and/or orientation of the user relative to the 3D video device. One or more auxiliary devices communicatively coupled to the 3D video device may be utilized to enable viewer perception and/or interaction with the 3D user interface.
