ヤンネル番号の「10」がCRT２上に表示される。 For example, when channel "10" is newly selected [a-1] by preset channel selection or direct channel selection, the microcomputer 9 selects "10".
The reception channel information D is transferred to the CRT character display signal generator 8 [a-2] so as to generate the character display signal C necessary for displaying the characters on the CRT 2. Further, the microcomputer 9 checks [a-3] whether the selected channel "10" is registered in the nonvolatile memory 10 or not, and if it is registered, the output lines 7 R , 7 G , Output line 7 B of 7 B is first inverted to logic level “H” [a-4]
Then, the output line 7G is inverted to logic level "H" [a-5]. If not registered, [a-
Execute [a-6] without executing [4] and output line 7.
R is inverted to logic level "H", and then [a-
5]. When output lines 7 B and 7 G are inverted to logic level "H", AND gates 5 and 6
A character display signal C of "10" is generated at each output, and the G cathode and B cathode of the CRT 2 are driven by the character display signal C via drive circuits 3 G and 3 B , respectively. Therefore, if registered, the receiving channel number "10" will be displayed in cyan, a mixture of green and blue.
is displayed on the CRT2. Furthermore, if it is not registered, the reception channel number "10" is similarly displayed on the CRT 2 in yellow, which is a mixture of red and green.

るだけで登録済か否かを識別できる。 The channel numbers received in this way are displayed on the CRT 2 in cyan and yellow depending on whether they are registered in the nonvolatile memory 10 or not, respectively.
You can tell whether a channel has been registered or not just by checking the color of the channel number display on the CRT2.

のである。Effects of the Invention As explained above, according to the present invention, when a channel is directly selected and switched by key-in on the keyboard, the new channel that has been switched is already registered so that it can be preset tuned. In order to determine whether or not the received channel number is displayed on the CRT and change the color of the received channel number between registered channels and unregistered channels,
It is possible to identify registered and unregistered CRTs at a glance.
