Abstract
The present invention relates to televisions (TV) and video tape recorders (VTR) which carry out the tuning operation by using a microcomputer. The microcomputer converts the modes in sequence of conventional air mode, cable TV Standard mode, cable TV Harmonic Relate Carrier mode, and multibroadcasting mode according to the inputted signal from a key matrix to control both the conventional and multibroadcasting modes which have different channels frequencies. Thus, independant systems or additional programs for multimode systems are not necessary.
