Abstract

PURPOSE: To attain agreeable channel selection by providing a skip signal generator which generates a signal for skips over channels where no broadcast signal arrives during sequential channel-selecting operation and a skip controller which inhibits the generation of the skip signal at a channel of a modulated video signal during individual channel selection.
CONSTITUTION: Tuning voltage generators VR1 and VR12, stored with turning voltages and code signals for tuing voltage generation, generte selectively a tuning voltage or code signals equivalent to a channel selection signal. A memory unit is stored with channel information of a modulated video signal. For individual channel selection, encoder 6 generates the channel selection signal through operations of channel selection switches S1∼S12 to make individual channel selection. For sequential channel selection, the channel selection signal is sequentially changed until reception of a desired channel is made. Skip signal generating circuit 11 generates one skip signal in a fixed period when skip control pulse Pg is held at a high level and monostable multivibrator M3 inhibits the generation of the skip signal by holding Q3' at a low level for fixed period from a channel change-over point during the individual channel selection.
