ABSTRACT:
A system and method for optically, serially transmitting data to a remote device using an interlaced display device. The data bits to be transmitted are ordered so that the bits are received in proper temporal order by the remote device. At least one of the data bits can be transmitted using the even-numbered horizontal scan lines of the interlaced display device. If all of the data bits can not be transmitted using the even-numbered horizontal scan lines of a usable transmission area, then at least one of the data bits can be transmitted using the odd-numbered horizontal scan lines of the interlaced display device. The binary data bits can be represented by illuminated and non-illuminated horizontal scan lines. An optical detector in the remote device can be used to receive the pulses of light, representing the data bits to be transmitted, from the horizontal scan lines.
