Abstract: A lighting system for a motor vehicle includes at least one lighting module capable of projecting lighting functions from image data, a control unit connected to the at least one lighting module by a data transmission channel and configured to generate a control image intended for the lighting module as a function of the optical features of the lighting module and of a setpoint datum. The lighting system also includes compression and decompression units to compress and decompress the image data while the data image travels between the control unit and the at least one lighting module.
