In a television receiver that uses a remote control, it is possible to visually check the adjustment target, that is, the function corresponding to the adjustment mode and the amount of adjustment, improving operability for the user.
This is an attempt to propose something that can reduce the number of erroneous operations.

The present application provides a television receiver in which a control signal representing an adjustment mode and an adjustment amount is supplied, and an adjustment circuit for the adjustment mode adjusts the adjustment amount by switching the adjustment mode and making adjustments using an up button and a down button. A remote control is used to carry out the volume adjustment, and has a first signal generator 2, 3, which is supplied with a control signal representing an adjustment mode and generates a character information signal indicating a function corresponding to the adjustment mode. The information includes characters to represent the adjustment mode and marks to represent the adjustment amount corresponding to the adjustment mode, and
is configured to generate an information signal of the color of the mark corresponding to the adjustment mode, a control signal representing the amount of adjustment is supplied, and a switching signal for moving the change point of the mark in accordance with the magnitude of the adjustment amount. The second signal generator 7 generates the first signal generator 2,
Based on the character information signal and color information signal uttered from 3, a display means is provided for simultaneously displaying characters to represent the adjustment mode and a mark to represent the adjustment amount on the screen, and a second signal is generated. Vessel 7
The adjustment amount and adjustment mode can be confirmed by moving the change point of a mark displayed simultaneously with the characters according to the adjustment amount based on a switching signal that is uttered by the user.

An embodiment of the television receiver according to the present invention will be described below with reference to FIG.

In FIG. 1, 1A and 1B are terminals to which analog data DATA1 representing the magnitude of the adjustment amount and mode data DATA2 representing the adjustment mode are supplied, respectively. In this case, for example, when adjusting the volume, color, and hue, these terminals 1
Adjustment mode analog data DATA1 and mode data DATA2 corresponding to A and 1B are supplied.

Mode data DATA2 supplied to terminal 1B
is supplied to the memory 2 as a control signal.

This memory 2 contains a character information generation signal Sch for generating character information to display a function corresponding to the adjustment mode, and a character information generation signal Sch corresponding to the adjustment mode.
A color information signal Scl having color information before and after the fall of the color switching signal Ssw as shown in FIG. 2E, which is generated by analog data DATA1 to be described later, is written in advance. Then, at the output terminals 2A and 2B of this memory 2, a character information generation signal Sch and a color information signal Scl of the adjustment mode corresponding to the mode data DATA2 supplied as a control signal are obtained.

Wind pulse as shown in
P _W is formed. This wind pulse _PW is supplied to the character information generator 3 as a timing signal. Therefore, in the character information generator 3, the second
As shown in Figure F, the horizontal period t _H within the vertical period t _V
, the character information Ich according to the character information generation signal Sch
is generated. In this case, the character information generation signal Sch
For example, when the text corresponds to color adjustment, the generated character information Ich is “｜｜｜｜｜｜｜
A display such as "COLOR|||||||" is displayed on the screen. This character information Ich is sequentially supplied to the color setting logic circuit 4.

Further, the window pulse P _W from the window pulse generator 6 is supplied to the color switching signal generator 7 as a timing signal. This color switching signal generator 7
is supplied with analog data DATA1 from terminal 1A, and in the end, in this color switching signal generator 7, it rises at the same time as the wind pulse _PW rises,
A color switching signal Ssw as shown in FIG. 2E, which falls after a delay time τ _A corresponding to the analog data DATA1, is formed. In this case, the larger the analog data DATA1, that is, the larger the adjustment amount, the larger the delay time τ _A becomes.

As described above, the color setting logic circuit 4 receives the color information signal Scl from the terminal 2B of the memory 2, the character information Ich as shown in FIG. A color switching signal Ssw as shown in FIG. E is supplied. In the color setting logic circuit 4, the character information Ich is expressed as a color signal whose color is different before and after the fall of the color switching signal Ssw, and the output terminal 4
The signals are output as red, green, and blue color signals to R, 4G, and 4B, respectively. In this case, the colors before and after the fall of the color switching signal Ssw are determined by the color information signal Scl, and for example, in the case of color adjustment, the before and after are red and the after are white. In this case, in the front, a red signal corresponding to the character information Ich is output only to the output terminal 4R, and in the rear, red, green, and blue signals corresponding to the character information Ich are output to the output terminals 4R, 4G, and 4B, respectively. A color signal is output.
