摘要:
A method, system, and computer program product for providing feedback over a multiple path network is provided. A first device sends a transmissions to a second device over at least two different paths of the network. Using information collected as a result of receiving the transmissions, the second device aggregates data regarding the performance of each of the paths together into a feedback message. The second device then sends this feedback message to the first device over one path of the network. The first device uses the data in the feedback message in its calculations for determining the relative performance of each path. The amount of traffic sent along each path is adjusted as appropriate, based on these calculations.
摘要:
A method of wireless communication includes aggregating data in a streaming communication session from a source node in a destination aggregator node, wherein data in the streaming session is transported over multiple paths from the source node to the aggregator node via a multipath overlay network discovered by the source node and the aggregator node.

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.

An apparatus, system, and method utilizing multi-description coding (MDC) for multimedia content with a plurality of forms of diversity. A source scene can be fragmented into one or more region of interest (ROI) portions and non-ROI portions, based on motion or any other metric of interest. One or more of these portions can further be fragmented by sub-sampling the respective portions to generate a plurality of lower-resolution versions, e.g., with alternating groups of pixels in respective versions. Still further, one or more of these portions can be further fragmented by image frames, e.g., with alternating frames in respective fragments. At least one ROI portion and lower-resolution versions may then be encoded into a plurality of descriptions and transmitted. Utilizing various combinations of ROI diversity, resolution diversity, and frame rate diversity can improve channel utilization and robustness for streaming multimedia content.

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.
