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： A sink device in a Wireless Display (WD) system may send performance information feedback to a source device to adjust media data processing at the source device. The performance information feedback may include performance indicators of the WD system that are capable of being measured or calculated at the sink device based on received media data or request to adjust the transmission of media data. For example, the performance information feedback may include one or more of round trip delay, delay jitter, packet loss ratio, error distribution, and received signal strength indication (RSSI). The feedback channel may be piggybacked on a reverse channel architecture referred to as the User Input Back Channel (UIBC) implemented between the source device and the sink device.

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： An end-to-end multimedia streaming system can include a streaming server and a destination. The streaming server includes a content source, which sends multiple description coding-encoded content over a plurality of paths to the destination. The destination includes an aggregator for aggregating the descriptions from the multiple paths, decoding and recombining them to recover the content. A feedback sender at the destination generates traffic performance variables based on the channel conditions of the multiple paths, and sends these variables to a feedback receiver at the streaming server. The feedback receiver utilizes the feedback information to make adjustments to the transmissions of the content, and to synchronize the transmissions over the multiple paths.

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.
