Abstract

PURPOSE:To evade a state in which channel selection is impossible and a sweep will not stop, by forcing channel selection on the TV side to advance to a following channel when channel search for the tuner part of a VTR channel selector can not be done even after channel selection of a TV receiver circuit is made by a channel selector. CONSTITUTION:A TV broadcast signal inputted from antenna 1 is divided into two by distributor 19; one signal is inputted to tuner part 2a of a channel selector for a TV receiver circuit, and the other to tuner part 2b of a channel selector for VTR. Next, VIF signals frequency-converted by tuner parts 2a and 2b are amplified and detected 3a and 3b and then video-amplified 4a and 4b before being outputted. Here, while tuner part 2a is stopping channel-selecting the TV broadcast signal of either channel, the channel search of tuner part 2a is advanced to a following channel forcibly if tuner part 2b can not search the TV broadcast station of this channel. Consequently, a state in which even if channel selection on the TV receiver side is done, it is impossible at the VTR side and a sweep will not stop can be avoided.
