Description

Function setting control method according to the menu method of TV

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a function setting control method according to a menu method of a television. More specifically, the menu item is simply designated by menuizing a function setting item for execution of a plurality of function operations assigned to the television. The present invention relates to a function setting control method according to a menu method of a television, which makes execution of a function operation simple.

[0003] In general, in a television that performs video playback and audio playback by tuning a video broadcast signal of a predetermined channel among video broadcast signals of multiple channels transmitted from a plurality of television broadcast stations, and processing video and audio signals, the multiple broadcast channels are used. In addition to the channel switching function for the video signal, the video signal contrast, brightness and color level of the video signal, such as the analogue level adjustment function and the volume of the audio signal is also provided.

In addition to the analog level adjustment function of the video / audio signal, an on-timer reservation function for turning on the operation power in the off state according to the elapse of the reservation time by using the on / off function of the operation power and the elapse of the reservation time The off-timer reservation function for turning off the operating power in the on state is employed. In the on / off-timer reservation function, the key operation of the matrix key of the remote control or the control panel is performed while the current time is set correctly. In the case of inputting the bedtime reservation time by means of inputting the desired bedtime time, the power of the on-state television is automatically turned off according to the elapsed time of the bedtime to notify the elapsed bedtime time. In case of input, input the desired wake up time and predetermined channel number. As a result, the power of the television in the off state is automatically turned on so that a television broadcast signal of a predetermined channel is outputted.

In addition, in a conventional general television, a single channel television broadcast signal is tuned through a single tuner, and the image is reproduced as a single screen through a CRT (Cathode Ray Tube) device which reproduces a single screen by processing video signals and audio signals. In order to solve the inconvenience of not being able to watch the television broadcast of the channel currently being viewed, when one is watching the television broadcasting of another channel as the audio signal is reproduced through the speaker which reproduces the audio of the single channel, one CRT apparatus A PIP (Picture In Picture) function (hereinafter referred to as a multi-screen playback function) is adopted to allow a sub-screen consisting of multiple screens to be inserted on the main screen (main screen) reproduced in the following.

In multi-screen TVs with such PIP functions, multiple channels of TV broadcast signals are tuned and signal-processed to output images through each designated screen, allowing simultaneous viewing of multiple channels of broadcast programs. Doing.

In addition, in addition to the stereo system, a voice system for a voice signal of a television broadcast is provided with a voice multiple system. A voice multiple system is a stereo broadcast system or a bilingual system that transmits another audio signal simultaneously to a voice carrier of a television broadcast. A method for adding a second voice carrier in addition to the existing voice carrier as a method of broadcasting a multi-carrier, and multi-modulation of a subcarrier modulated by a dual carrier system and a negative voice to a conventional voice carrier. The system is classified into a subcarrier system, which is a system, and enables multiplexing of audio according to the audio multiplexing method on the television side.

However, it is possible to set up function execution for a number of functional operations such as channel switching, analog level adjustment of video / audio signals, multiplexing of audio signals, and on / off timer reservation functions employed in such televisions. In order to perform the function setting in detail by manipulating the designated function keys for each function operation, there is a disadvantage in that inconvenience in use is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the function setting items for channel switching, video / audio adjustment, and other functions assigned to televisions are sub-menu items dependent on a plurality of main menu items and respective main menu items. It is an object of the present invention to provide a function setting control method according to a menu method of a television which allows a screen to be displayed in the form of an overlay display signal so that a predetermined function can be easily executed by designating a menu item. .

In order to achieve the above object, according to the function setting control method according to the menu method of the television according to the present invention, a plurality of main menu items designated for a plurality of functions assigned to the television by the mode execution of the function setting mode are integrated. A first step of displaying a screen, and when a predetermined main menu item is selected from the plurality of main menu items, a plurality of sub-items subordinate to the corresponding main menu item among a plurality of sub-menu items dependent on the plurality of main menu items. The second step of overlaying the sub-menu item having a display screen, and if a predetermined sub-item is selected from the overlaid sub-menu item is displayed, the third step of executing a function or setting operation for the corresponding sub-item Provides a function setting control method according to the menu method.

According to the present invention configured as described above, a plurality of channels such as a channel switching function and an analog level adjustment function of a video / audio signal, a stereo / voice multiple / surround processing function of an audio signal, an on / off timer function, etc. A plurality of main menu items corresponding to the function are to be displayed on the integrated screen, but if a predetermined main menu item is selected, the sub menu items dependent on the main menu items are displayed in an overlay form, and the sub menu items are displayed. If a predetermined small item is selected from among the plurality of small items assigned to, the predetermined function operation is executed or the level setting operation is performed.
