Abstract
PURPOSE:To save the transmission line and eliminate a frequency characteristic compensating circuit at the receiving terminal, by multiplying in time division both a timing pulse and control data on a coaxial transmission line in the camera cable. CONSTITUTION:A camera control horizontal driving signal HD201 applied to an input terminal 11 of a camera control unit CCU1 is compared in phase with the HD transmitted from a camera head 2 in the form of a timing pulse by a phase comparator 101. A voltage control oscillating circuit 107 is controlled by an errorsignal 202 which is converted into a DC. The output of the circuit 107 is supplied to a synchronous synthesizer 109. An even field pulse 203 transmitted to the head 2 from the CCU1 is mixed with a data 204 through a NAND circuit 203 and supplied toward the head 2 through transmitting/receiving circuits 102 and 108. At the head 2 side, the even field pulse is separated by an even field separating circuit 111 to be applied to a V reset terminal of the synthesizer 109. The data sent to the head 2 side is supplied to an output terminal 16 after converted 113 into a parallel data.
