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： 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： An apparatus, system, and method utilizing multi-description coding (MDC) and one or more cooperative helper nodes to send streaming content on an uplink to a client over multiple paths. The client receives the multiple descriptions and aggregates them together to ideally obtain the original content at its original quality; however, if one or more of the descriptions is lost in the transmission, then the entire content can be generated from the remaining one or more descriptions that did arrive successfully.

摘要： 3D image data can be modified based on user preference data received from a user. The user preference data may be received at a first device and used to adjust 3D image data generated by the first device for presentation by a display device, or the first device may receive the user preference data and transmit it to a display device such that the display device may adjust the 3D image data based on the user preference data. The 3D image data may be adjusted based on user preference data to support presentation of 3D imagery on the display device in a manner desired by a user. 3D user viewing preferences may include an amount of pop-out effect in images, a stereo baseline of images, a depth range of images, a spatial distribution of images, a degree of depth sharpness in images, or specification of a user's dominant eye.

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： A wireless communication method includes an aggregator requesting a first description substream of a multimedia service from a source over a first path, receiving confirmation that the source is available, and receiving a first substream of the service. The method includes determining if a quality of the first substream is satisfactory, and requesting to receive the multimedia service over at least one additional path from the same source. A wireless method of communication by a source device includes receiving a multimedia service request from an end device aggregator over a first path, sending an confirmation that the source is available and sending a first substream over the first path in response to the request. The method includes receiving a request to send the multimedia service over at least one additional path to the end device aggregator from the same source.
