Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device having various setting functions, and more particularly, to the operation of the setting program even after the setting program is started up so that the state before the setting can be returned by one touch. Operation of the video display device
The present invention relates to a video display device having a manufacturing method and an operation function .

2. Description of the Related Art In some large television receivers, BS broadcasts transmitted from satellites are transmitted as high definition video signals (HD
In addition to being equipped with a device for receiving as a TV, it is possible to monitor normal television broadcasts, UHF broadcasts, and video signals supplied from the outside.

In such a high-end type television receiver, all kinds of operations are performed under the control of a microcomputer. For example, the color of the video image screen, the sharpness control, the sound quality adjustment, the operating time and the ending time are performed. There are many built-in setting programs such as the settings, channel settings, BS antenna sensitivity adjustment, etc. Therefore, if you start up such a setting program according to the instruction manual and set various operations and characteristics of the TV receiver in advance, the optimum screen is automatically formed and broadcast at any time. Will be able to receive. Further, the AI function of the television receiver can automatically set or reserve a program desired by the user.

[0004]

However, in such a television receiver, when the desired data (numerical value) is input by various operation keys after the setting program is started, the operation is performed according to a certain procedure. There is a need. However, if the procedure is lost during the setting operation, or if the setting operation becomes troublesome, the operation is interrupted. In this case, the procedure for returning to the state before the original setting is lost, and in the end, there is no choice but to turn off the power supply once to reset it.

[0005]

In order to solve such a problem, the present invention allows a microcomputer having a built-in setting program to operate a release key, and when the release key is pressed. Is for exiting the setting mode and transiting to the state before the first setting.

[0006]

When any of the setting operations is performed, the state before the setting can be restored by pressing the release key, so that the user can try various setting operations with peace of mind.

1 is a block diagram of a TV receiver of the present invention, in which 1 is a tuner for selecting a broadcasting station, 2 is an intermediate frequency amplifier, and 3 is a demodulated video signal processing circuit. As shown, various kinds of processing such as color signal separation, color difference signal formation, and synchronization signal extraction are performed, and RGB signals are supplied to a CRT (CRT) 4 for visualization. Reference numeral 5 denotes a control unit that outputs a control signal to each of the functional circuits, and this control unit 5 broadcasts based on an operation signal of the remote controller 8 input from the input key switch (operation button) 6 or the light receiver 7. Performs station selection, volume up / down, and various image quality controls. The input key switch 6 or the remote controller 8 is provided with a setting cancel key so that various setting operations can be cleared by the setting cancel key as described later. Reference numeral 9 indicates a character (graphic) generator for superimposing and outputting various information on the display screen.
Has a function of displaying the content of the operation when the control data is output from the control unit 5 in characters.

Further, it is also possible to insert an image for displaying an external video signal, a BS video signal, etc. input to the video signal processing circuit 3 on a parent-child screen. Inside the control unit 5 of the present invention, a CPU and a RAM,
In addition to a semiconductor memory such as a ROM, a clock circuit TC, a setting program memory M, and the like are provided so that various settings of the TV receiver can be performed. 1
Reference numeral 0 is a voice generator, 11 is an amplifier, and 12 is a speaker, which are used when outputting the advice information by voice. The TV receiver of the present invention is equipped with the above-mentioned circuit blocks so that, for example, the remote controller 8 turns on / off the power supply, selects the broadcasting station, adjusts the volume, and the like, similarly to a normal TV receiver.

When a particular input key switch (operation button) is turned on, this TV receiver turns on the power switch at a certain time and turns off the power after a predetermined time. Settings for registering UHF broadcast channel selection for channel, image quality (picture, Hue, colo)
r)), etc., and if a BS broadcast tuner is provided, a setting mode for displaying the antenna level (AGC level) on the screen to adjust the receiving antenna can be obtained. There is.

FIG. 2 shows a flow chart which operates when the control unit 5 enters the various setting modes as described above. When the setting mode is entered by operating the input keys (F11), the CPU first The various data before this setting is stored in the memory (F12), that is, the state before the setting data which changes from now on is stored. Then, it is always determined whether or not the setting release key is pressed (F1
3) The data set by the user is stored in the RAM while the setting release key is not pressed. Then, when the setting end key is finally pressed (F15), this setting operation is ended and the next setting mode is waited for. Further, if the setting order is wrong at the stage of inputting the setting data in step (F13) or the setting is canceled midway, the setting cancel key can be pressed. Then, in the case of the present invention, all the setting data that have been input halfway are cleared (F16), and then the data before the setting (F1) stored in the previous step (F12) is cleared.
2) is read and the state before setting is returned (F18). Therefore, it is possible to return to the original setting state only by pressing the setting release key, and the user can operate with peace of mind. In addition, there is no fear that various data that have already been set will be changed.

Although the above embodiment has been described with respect to the TV receiver, it can be applied to all electronic devices for which setting operation is performed. For example, when a complicated operation such as a VTR (Video Tape Recorder) recording time setting operation is performed, erroneous data input or a lot of steps before and after the procedure occur. If you can do this, you will feel safe in operation, and the practical effect will be great.

[0012]

As described above, the electronic device having the setting function of the present invention has the function of resetting the setting input and returning to the state before the setting after entering the setting mode. Even when a person who is unfamiliar with the electronic device performs a difficult setting operation, there is a practical effect that the input operation can be performed with confidence and the user can easily handle the input operation.
