CONTROL SIGNAL GENERATING CIRCUIT, VIDEO DECK HAVING THE SAME, AND METHOD FOR GENERATING CONTROL SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a control signal generating circuit which can reduce complications in the design of a signal pattern, a video deck using the circuit, and a method for generating control signals. ;SOLUTION: A control signal generating circuit enables a system controller 40 to output control signals with three levels which consist a lower level (L), a middle level (M), and a high level (H) and, at the same time, receives the control signals by means of an output changeover switch 80 and controls switching operation by recognizing a VCR 1ch output mode, a VCR 2ch output mode, and TV mode according to the signal levels of the control signals. Thus, complications in the design of a signal pattern can be reduced, because it is not required to individually design the control signals which are used for switching the output channels and TV/VCR modes.;COPYRIGHT: (C)1999,JPO
