Description

Televideo device with key button common function

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a televideo apparatus, and more particularly, to a televideo apparatus having a key button common function, which is provided with a plurality of key buttons and can be shared as a function button of each mode state according to a selected mode.

In general, televideo (hereinafter referred to as TVCR) is a home appliance having both a TV and a VCR function. ) Is a device in which video signals and audio signals reproduced on a video tape are reproduced through the television.

Therefore, in the television, the TV mode for reproducing the video signal and the audio signal transmitted from the broadcasting station and the VCR mode for reproducing the video signal and the audio signal of the videotape are selectively set through the key input unit. The playback signal is switched.

However, the key input unit for selecting the TV mode or the VCR mode is provided with a function button for operating the mode, respectively, and a plurality of function buttons for operating the TV mode and a plurality of function buttons for operating the VCR mode. Occupies a number of buttons.

Therefore, when a function key is operated in accordance with the mode selected through the key input unit, a large number of key buttons are not recognized at a glance, and thus, a different key button is often entered rather than a desired key input.

In addition, due to the large number of key buttons, not only it looks complicated in aesthetic appearance, but also the circuit configuration according to the key button is increased, so that the number of parts increases, and the circuit for processing a large number of key button inputs becomes complicated. There is a limit in designing the external appearance of the televideo device.

Accordingly, the present invention has been made in view of the above-described circumstances, and has a key video sharing function having a key button sharing function that allows a key button to be shared by using a corresponding function button according to a selected mode with a few key buttons. The purpose is to provide.

Tele video device having a key button common function according to the present invention for realizing the above object is a tuner for reservation recording, a deck for recording a broadcast signal tuned by the tuner, and reproduced from the tuned broadcast signal and deck A televideo apparatus comprising a signal processor for processing a reproduction signal and outputting video and audio signals, and a CRT driver for driving a CRT based on the video signal output from the signal processor; A key input unit having a select key for selecting a desired mode, a key input unit having a few key buttons, a mode state storage unit for storing the mode selected by the key input unit, and a function corresponding to the key button according to the selected mode Key data storage unit, OSD pattern data storage unit for storing the OSD pattern data for the function guide corresponding to each key button, OSD generation for outputting a predetermined OSD guide subtitle for the function of each key button according to a predetermined control signal When a predetermined mode is selected through the key input unit, the selected mode is set to a mode state storage unit and the OSD generator is controlled based on the OSD pattern data stored in the OSD pattern data storage unit to correspond to each key button. And a control unit for controlling a function of outputting the function to a predetermined OSD guide subtitle and then performing a function corresponding to the input key button. Characterized in that comprised over.

According to the present invention having the above-described configuration, it is possible to use a function button of the corresponding key button according to the selected mode of TV or VCR with a few key buttons, thereby realizing a key button that can be shared in both modes.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 is a block diagram showing an internal configuration of a televideo device having a key button sharing function according to an embodiment of the present invention.

In the drawing, reference numeral 1 denotes a key input unit provided with a selection key 1a and a few function keys for selecting a desired mode, and 2 denotes a mode state storage unit for storing the mode selected by the key input unit 1; , 3 is a key data storage unit for storing a function corresponding to a key button according to the selected mode.

In addition, reference numeral 4 is an antenna for receiving an over-the-air signal, 5 is a first tuner for tuning a broadcast channel selected by a user according to a predetermined control signal, and 6 is a second tuner for tuning a broadcast channel for which reservation recording is set. , 7 is a deck for performing recording and playback operations according to predetermined control.

In addition, reference numeral 8 is a signal processor for processing a broadcast signal tuned by the first tuner 5 and a reproduction signal reproduced in the deck 7 to output a video and sound signal, 9 is a CRT driver for driving the CRT 10 based on the video signal output from the signal processor 8, and 11 is a speaker 12 connected to the rear end by amplifying the audio signal output from the signal processor 8; It is a voice amplifier output through.

In the drawing, reference numeral 13 denotes an OSD pattern data storage unit for storing OSD pattern data relating to a function guide corresponding to each key button, and reference numeral 14 denotes a predetermined OSD guide subtitle for a function of each key button according to a predetermined control signal. The OSD generator 15 for outputting the R, G, B and blanking signals Y 'outputted from the OSD generator 14 and the video signal outputted from the signal processor 8 are connected to the rear stage. The mixer outputs to the CRT driving unit 9.

In addition, reference numeral 16 denotes OSD pattern data stored in the OSD pattern data storage unit 13 in addition to setting the selected mode to the mode state storage unit 2 when a predetermined mode is selected through the key input unit 1. The control unit controls the OSD generator 14 to output a function corresponding to each key button as a predetermined OSD guide subtitle, and to perform a function corresponding to the input key button.

Next, the operation of the device having the above configuration will be described with reference to the operation flowchart shown in FIG. 3.

First, when the power of the tele video device is turned on (step ST1), the controller 16 controls the function based on the mode preset in the mode state storage unit 2, for example, the preset mode. If is in the TV mode to control the function related to the TV is performed.

On the other hand, if the user presses the selection key 1a to select the desired mode through the key input unit 1 (step ST2), the controller 16 newly sets the selected mode in the mode state storage unit 2. (ST3 stage).

Then, the OSD generating unit 14 is controlled based on the OSD pattern data for function guidance corresponding to each key button stored in the OSD pattern data storage unit 13, as shown in FIG. The function corresponding to the button is output as a predetermined OSD guide subtitle (ST4 step).

For example, if the preset mode is in the TV mode, when the selection key 1a of the key input unit 1 is input, the mode is converted into the VCR mode, and the VCR is displayed on the bottom of the screen as shown in FIG. 2 on the CRT 10 screen. OSD guided subtitles are displayed to guide key button functions according to the mode status.

On the other hand, if the selected mode is a TV mode, as shown in Figure 2 on the screen of the CRT (10) OSD guided subtitles for guiding the key button function according to the TV mode state is output.

Subsequently, when there is a predetermined key input after the function guide subtitle of the key input unit 1 is output (step ST5), the control unit 16 functions data corresponding to the key button stored in the key data storage unit 3. Based on this, the function according to the key input is controlled to be executed (step ST6).

That is, according to the above embodiment, it is possible to realize a televideo apparatus which can be shared in both modes with a few key buttons.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, it is possible to realize a televideo device which can be shared in both modes with a few key buttons.
