摘要： Methods and systems for distributed infrastructure for streaming data via multiple access points. Aspects of one method may include apportioning multimedia information among a plurality of transmitting devices based on feedback channel information received from a destination receiving device by, for example, a transmission controller device. The transmitting devices may transmit the multimedia information to the destination receiving device. A transmitting device that may not be apportioned multimedia information may transmit a probing signal. The destination receiving device may generate feedback channel information for a transmitting device, for example, based on the multimedia information or the probing signal received from the respective transmitting device. The apportioning of the multimedia information may be dynamically adjusted based on updated feedback channel information received from the destination receiving device.

摘要： Enhanced performance is achieved by combining channel coding with the space-time coding principles. With K synchronized terminal units transmitting on N antennas to a base station having M≧K receive antennas, increased system capacity and improved performance are attained by using a concatenated coding scheme where the inner code is a space-time block code and the outer code is a conventional channel error correcting code. Information symbols are first encoded using a conventional channel code, and the resulting signals are encoded using a space-time block code. At the receiver, the inner space-time block code is used to suppress interference from the other co-channel terminals and soft decisions are made about the transmitted symbols. The channel decoding that follows makes the hard decisions about the transmitted symbols. Increased data rate is achieved by, effectively, splitting the incoming data rate into multiple channels, and each channel is transmitted over its own terminal.

摘要： A monoscopic video camera may capture, via at least one image sensor, two-dimensional video, and may capture, via at least one depth sensor, corresponding depth information for the captured two-dimensional video. The monoscopic video camera may then detect and/or track objects in the captured two-dimensional video based on the captured corresponding depth information; and processing of image related information corresponding to the objects may be configured based on the detecting and/or tracking of the objects. Type and/or characteristics of each of the objects may be determined during the detecting and/or tracking. Identification of the type and/or characteristics of the objects may be performed based on one or more object recognition algorithms programmed into the monoscopic video camera. Configuration of processing of object image related information may be performed based on preset criteria and/or parameters associated with identified types and/or characteristics of the objects.
