Abstract: Systems and methods for providing optical communication between a vehicle and an external actor include a system provider device that establishes, through communication over a network with at least one vehicle, the at least one vehicle as a communication proxy. Establishing the at least one vehicle as a communication proxy may include pairing the at least one vehicle with a user device. In various embodiments, the system provider also receives a communication trigger. In response to the communication trigger, the system provider may transmit a modulated optical signal via an illumination source of one of the at least one vehicle and an external actor, to the other of the at least one vehicle and the external actor. The system provider detects, at the other of the at least one vehicle and the external actor, the modulated optical signal and demodulates the transmitted optical signal.

Abstract: Method, system and computer program product for replacing a portion of a digital signal by applying a first difference correction that, after range limiting, converts the samples in the replacement portion to extremum values; then applying a second difference correction based on the difference between the extremum values and the desired replacement values. The first and second sets of correction values are thus independent of the original values in the first digital signal.
