Abstract: A system reduces noise or other external signals that may affect communication. A device converts sound from two or more microphones into an operational signal. Based on one or both signals, a beamformer generates an intermediate signal. Reflected or other undesired signals may be estimated or measured by an echo canceller. Interference may be measured or estimated by processing the echo-reduced signal or estimate by a blocking matrix. An interference canceller may reduce the interference that may modify or disrupt a signal based on the output of the blocking matrix and the intermediate signal.

Abstract: A system and method for estimating a geolocation of a non-cooperative target using any reasonable target location estimate. Collectors may acquire actual signal measurements including a direction of arrival (DOA), a target range, a time difference of arrival (TDOA), a range rate, a range sum, and/or a frequency difference of arrival (FDOA). A processing device may receive the actual signal measurements and navigational data regarding the collectors. Then, the processing device may calculate an estimated target location as a solution to a nonlinear optimization problem where an objective function to be minimized is a weighted sum-of-squares of differences between the actual signal measurements and calculated values corresponding to signal measurements that theoretically should be produced for a particular target location. The algorithm used to solve this problem may be a globally convergent algorithm, such as a Levenberg-Marquardt algorithm.

Abstract: An audio enhancement refines a short-time spectrum. The refinement may reduce overlap between audio sub-bands. The sub-bands are transformed into sub-band short-time spectra. A portion of the spectra are time-delayed. The sub-band short-time spectrum and the time-delayed portion are filtered to obtain a refined sub-band short-time spectrum. The refined spectrum improves audio processing.

Subsequently, a session may be established between a DLNA device to the media server through the tunnel using a virtual address, where the media server is addressable as a virtual device within the DLNA network so that the virtual address is part of an address space of the DLNA network. The media server may support a plurality of DLNA networks, in which a tunnel is established to the media service for each DLNA network.

Abstract: Methods, systems, and media are provided for rights protection of an instance of media content in a hybrid downloading and streaming media environment. A request from a device to download an instance of media content is communicated. Verification is obtained as to whether or not the device is authorized to receive and execute the instance. The instance of media content is streamed so that portions may be downloaded. The instance of media content also includes interspersed, non-storable authorization information. When subsequent execution of the instance of stored media content is attempted, a subsequent request for the authorization information is communicated. Only the authorization information is streamed for the subsequent request, allowing execution without burdening network resources with data-intensive streams.
