word as illustrated in fig1 the preferred embodiment does not actually use redundant control words but envisions using start of line sol 1 sol 2 control words having different bit patterns other embodiments sending identical bit patterns are also envisioned as are embodiments using separate handshaking lines the preferred embodiment employs start of line control words having different bit patterns because the synchronous nature of the preferred embodiment is enhanced by the individual decoding at the receiver of each of the control words the preferred embodiment has data and control words transmitted across the same bus and timing considerations are crucial in such a synchronous design separately decoding each of the control words allows timing configurations with respect to data that is transferred across the same bus to be established the timing between the reception of the start of line sol 1 sol 2 control words to the beginning of a line of image data is a predetermined number that is known to the receiver the technique of sending multiple control words could be extended by sending a different number call it u2018 n u2019 of control words wherein the probability of at least one control words being correctly identified by the receiver improves as u2018 n u2019 increases the system shown in fig3 is very much like fig2 but illustrates an implementation of the preferred embodiment to solve the aforementioned problems as shown in fig3 the transmitter receives a start of frame sof control word as an indication.
