摘要： A system transmits human interface data (HID) as ancillary data to a television receiver over white space. Content on a user mobile device may be wirelessly displayed on an external display device. It may be desirable to have user interactions with the mobile device (such as controls for video games) displayed on the external display device in a manner that does not suffer from the latency of standard video being set to the display device. The HID may be captured and processed separately from the video data. The HID may be formed into a transport stream for transmission over white space. The HID may be included as ancillary data in the transport stream. Timestamps may be used to coordinate the transmission of the HID as well as its processing when received by a television receiver.

摘要： An apparatus, system, method, and computer program product for streaming 3D content from a wireless device to a remote 3D display for the viewing of the 3D content on a larger screen. In some aspects, a wireless streaming server may encode 3D motion picture content in a certain format, where each image frame includes a 2D view concatenated side-by-side with a complementary frame of depth information. The combination of the 2D view and the depth information are capable of being processed by a client display to generate a stereoscopic image representing a 3D view.

摘要： White space devices are operable to communicate information over white space and, more specifically, to quiet a transmitter to enable sensing signals in the white space. A method for inconspicuous quieting of a transmitter in a white space communication device modifies a transport stream for transmission by the transmitter of the white space device to provide a null window of time. The null window does not contain essential information. At least a portion of the modified transport stream is transmitted by the transmitter of the white space device. The transmitter is quieted during the null window, and white space sensing is performed during the null window.

摘要： In general, techniques are described for transforming video data in accordance with a three dimensional (3D) input format. As one example, an apparatus, such as a mobile or portable device, that includes a transformation module, a parameter discovery module and at least one interface implements the techniques. The parameter discovery module determines an input format supported by a 3D display device. The parameter discover module then configures the transformation module to transform two-dimensional (2D) video data into 3D video data so as to generate the 3D video data in accordance with the determined input format. The at least one interface receives 2D video data. The transformation module transforms the 2D video data to 3D video data so that the 3D video data complies with the determined input format. In this manner, the apparatus implements the techniques to transform video data in accordance with a determined 3D input format.

摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

摘要： Techniques for video encoding and decoding a common guide media logic channel (MLC) to enable fast acquisition and re/synchronization of the video stream while preserving compression efficiency are provided. Systems and methods to process multimedia data using channel switch frames are presented. The system comprises an encoder operative to generate a common guide media logical channel (MLC) of a plurality of channel switch frames (CSFs), each respective active channel having one or more CSFs in the guide MLC. The decoder in the system is operative to decode a set of the plurality of CSFs from the guide MLC. The decoder simultaneously displays programming content of the decoded set of the plurality of CSFs on a display and automatically switches to a primary bitstream of an active channel associated with a selected one displayed CSF.
