Abstract: A system for encoding a sequence of frames (171) of a data signal. The system comprises: a first encoding system (120) comprising at least: a first encoder (130) configured to encode the sequence of frames (171) according to a first encoding algorithm; and a first rate control unit (135) configured to control a first bit rate at which the first encoder (130) encodes said sequence of frames (171); a second encoding system (100) comprising at least: a second encoder (116) configured to encode a second sequence of frames (175) associated with the sequence of frames (171) according to a second encoding algorithm; and a second rate control unit (135) configured to control a second bit rate at which the second encoder (130) encodes said second sequence of frames (175) associated with the sequence of frames (171).

Abstract: A vehicular warning system includes a plurality of input devices. A computing unit is electrically coupled to the input system. An input preprocessing classifies signals received from the plurality of input devices into Vehicle information, Roadway information, Traffic information, and eXogenous information (“VRT-X”) data structure. The early warning processing unit observes the VRT-X signal provided by the input preprocessing unit corresponding to an environment surrounding a vehicle, predicts future changes in the environment over a dynamically-configured range, and determines signal properties in both time and frequency domain over a moving window. Based on defined early warning classification rules, the computing unit assigns a threat level to the VRT-X signal corresponding to the environment surrounding the vehicle.

Abstract: First and second pluralities of residual elements useable to reconstruct first and second respective parts of a representation of a signal are obtained. A transformation operation is performed to generate at least one correlation element. The transformation operation involves at least one residual element in the first plurality and at least one residual element in the second plurality. The at least one correlation element is dependent on an extent of correlation between the at least one residual element in the first plurality and the at least one residual element in the second plurality. The transformation operation is performed prior to the at least one correlation element being encoded.

Abstract: A set of reconstruction elements useable to reconstruct a representation of a signal at a relatively high level of quality using data based on a representation of the signal at a relatively low level of quality is obtained. The representation at the relatively high level of quality is arranged as an array comprising at least first and second rows of signal elements. A reconstruction element is associated with a respective signal element in the set. A set of data elements is derived based on the set of reconstruction elements. At least one of the data elements is derived from at least two reconstruction elements associated with signal elements from the first row and a different number of reconstruction elements associated with signal elements from the second row.
