1. A method for transmitting control instructions to a plurality of receivers, the method comprising:
modulating a plurality of light sources to generate a plurality of corresponding light beams, each light source being modulated with a corresponding digital data stream for inducing corresponding control instructions in the corresponding light beam; and
applying each of the plurality of light beams to a corresponding pixel shaper element of a pixel shaper assembly to produce a plurality of distinct light pixels, each distinct light pixel emitted by the pixel shaper assembly carrying the corresponding control instructions of the corresponding light beam, each distinct light pixel having a perimeter defined by the corresponding pixel shaper element, the plurality of distinct light pixels being directed toward a projector lens, the projector lens transmitting the plurality of distinct light pixels toward the plurality of receivers, wherein:
each receiver of the plurality of receivers is contained once in a plurality of receiver groups,
each receiver group contains one or more receivers, and
the pixel shaper assembly is configured to direct each of the plurality of distinct light pixels toward a corresponding one of the plurality of receiver groups for carrying the corresponding control instructions to the one or more receivers contained in the corresponding one of the plurality of receiver groups.
