Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.
