Abstract: An array of audio transducers includes an optical emitter, for example, and without limitation, a light emitting diode (LED), associated with each transducer. Simultaneous stimulation of all transducers illuminates all LED's. An imager then creates a map of the transducer array. Stimulation of a single transducer, illuminating the associated LED, creates an optical signature that imaging software uses to determine the position of the transducer within the array. The system then verifies the correspondence between each transducer and the associated driver amplifier by sequential stimulation of each transducer within the array. The system may vary the frequency of the stimulation applied to transducers that include filtering networks, known as crossovers, to validate performance. Further, the system may compute the angles between transducer assemblies that may be deployed in non-planar configurations, thus ensuring that the installation is constructed to specifications.

Abstract: Video blocks of stereo or non-stereo video sequences are coded using a parameterized motion model. For example, encoding a current block of a stereo video sequence can include determining a block-level disparity between first and second frames and identifying plane normal candidates within the current block of the first frame based on the block-level disparity. One of the plane normal candidates is selected based on rate-distortion values, and warping parameters are determined for predicting motion within the current block using the selected plane normal candidate. The current block is then encoded using a reference block generated by applying the warping parameters. Decoding that encoded block can include receiving a bitstream representing an encoded stereo video sequence, determining warping parameters for predicting motion within the encoded block based on syntax elements encoded to the bitstream, and decoding encoded block using a reference block generated by applying the warping parameters.
