1. A television on-channel selecting apparatus comprising:
- (a) first signal input means for receiving signals from a first broadcasting system;
(b) second signal input means for receiving signals from a second broadcasting system;
(c) first tuner means for tuning a plurality of channels of said first broadcasting system and an auxiliary channel;
(d) second tuner means for tuning a plurality of channels of said second broadcasting system and for outputting a signal on said auxiliary channel;
(e) switching means connected to receive an output of said first signal input means and an output of said second tuner means and for providing an output to said first tuner means;
(f) key means for controlling said first tuner means to sequentially select said plurality of channel of said first broadcasting system and said auxiliary channel;
(g) indicating means responsive to said first tuner means for indicating a selected one of said plurality of channels of said first broadcasting system as numerals, and said auxiliary channel, when selected, as a non-numeral character;
(h) control signal generating means connected to said key means and to said first tuner means for supplying channel selection signals to said first tuner means and switching signals to said switching means, said control signal generating means causing said first tuner means to sequentially select channels of said first broadcasting system by keys corresponding to said numerals and said non-numeral character, and said control signal generating means supplying a switching signal for automatically selecting the output of said second tuner for connection to said first tuner only when said auxiliary channel is selected.

14. A television on channel selecting apparatus comprising:
-
(a) first signal input means; (b) second signal input means; (c) switching means for switching an output of said first signal input means and an output of said second signal input means; (d) selecting means for selecting a signal on a desired channel from one of the outputs of said first and second signal input means switched by said switching means; and (e) control signal generating means for supplying a channel selection signal to said selecting means, wherein said control signal generating means includes a routine for sequentially selecting channels from said first signal input means and said routine includes a switching mode for supplying a switching signal to said switching means, wherein the operation of said switching means is carried out continuously and sequentially, and said selecting is made at a slower speed in the vicinity of a predetermined switching mode.
