The system and method of the present invention optically transmits redundant
packets of data using infrared signals at pseudo-random intervals to allow a receiver
to distinguish between multiple simultaneous sources. The emitters repeatedly transmit
a short packet at randomized intervals much shorter than the frame rate. Statistical
analysis shows that the probability of collision of the desired packet with a packet
from some other source is sufficiently low such that timely reception of at least
one uncorrupted packet in the required time frame is assured.
