摘要： Television white space devices are operable to communicate information over television white space and, more specifically, to quiet a transmitter for sensing signals in the television white space. A method for inconspicuous quieting of the transmitter in a television white space device inserts, from an application layer, information into a transport stream for transmission by the transmitter of the television white space device to produce a null window of time within the transport stream at a predetermined time. The method also transmits the transport stream by the transmitter of the television white space device and quiets the transmitter during the null window of time. The method senses, by a white space sensor of the television white space device, existing signals in the white space during the null window of time.

摘要： Mobile media server (MMS) includes MMS hosts and an MMS clients utilized for ubiquitous sharing of media content. An MMS host, which may be deployed on a mobile terminal such as a cellular telephone, can establish a logical link with an MMS client over an IP interface and initiate a streaming session with the MMS client. The MMS host may further retrieve media content from any source, such as a network source, locally stored content, or a camera and/or microphone on the MMS host, and serve the media content to the MMS client over the logical link.

摘要： In general, this disclosure describes techniques for encoding and decoding sequences of video frames using fragmentary reference pictures. The disclosure presents video encoding and decoding techniques for modified temporal compression based on fragmented references rather than complete reference pictures. In a typical sequence of video frames, only a portion (i.e., a tile) of each frame includes moving objects. Moreover, in each frame, the moving objects tend to be confined to specific areas that are common among each frame in the sequence of video frames. As described herein, such common areas of motion are identified. Pictures are then extracted from the identified areas of the video frames. Because these pictures may represent only portions of the frames, this disclosure refers to these pictures as “fragments.” It is then these fragments that are used as reference pictures for generating predicted frames during a motion compensation process, rather than the entire frame.
摘要翻译： 通常，本公开描述了使用片段参考图片对视频帧的序列进行编码和解码的技术。 本公开提供了基于分段参考而不是完整参考图片的用于修改的时间压缩的视频编码和解码技术。 在典型的视频帧序列中，每个帧的仅一部分（即瓦片）包括运动对象。 此外，在每个帧中，移动对象倾向于被限制在视频帧序列中的每个帧中共同的特定区域。 如本文所述，识别这样的公共运动区域。 然后从视频帧的识别区域中提取图像。 因为这些图片可以仅表示帧的一部分，所以本公开将这些图片称为“片段”。 那么这些片段被用作用于在运动补偿过程期间生成预测帧而不是整个帧的参考图像。

摘要： This disclosure describes adaptive video encoding and decoding techniques for encoder-assisted frame rate up-conversion (EA-FRUC). An encoder selectively encodes at least a portion of a video frame, such as a block, using an interpolated FRUC frame as a reference. The encoder interpolates at least a portion of the FRUC frame at the same time instance as the yet to be encoded video frame, and selects one of a plurality of FRUC encoding modes for that portion, e.g., based on rate distortion (RD). The encoder encodes the frame using the selected FRUC encoding mode, the FRUC reference frame, and any additional reference frames that may be indicated. A decoder interpolates the FRUC frame and uses it or decoding with knowledge of the particular FRUC mode that was used by the encoder. The encoder communicates the FRUC mode for a block via one or more existing parameters in the encoded video frame.

摘要： In one example, this disclosure describes a method that includes, in an example, determining, by a source device, that display data rendered by the source device comprises one or more displayable graphical objects. The method also includes in response to determining an event, selecting, by the source device, a set of the one or more graphical objects for rendering at a sink device. The method also includes generating, by the source device, configuration data based at least in part on the set of the one or more graphical objects, wherein the configuration data is usable by the sink device to render representations of graphical objects in the set of one or more graphical objects based at least in part on one or more display parameters associated with the sink device. The method also includes sending, by the source device, the configuration data to the sink device.
