Abstract

PURPOSE:To ensure a high-contrast display in the remote control of a TV set, a VTR, etc., by providing a liquid crystal display matter with correspondence to a function key and switching the operation of the function key and the display of the liquid crystal display matter with interlocking to the switch of a changeover key. CONSTITUTION:A housing 1 contains changeover keys 2a-2c which switch the control of a TV set, a VTR and a multiplex character receiver, ten-keys 3a- 3j which are used in common with changeover of channels, designation of programs, etc., function changeover keys 4a and 4b, and liquid crystal display matters 5a and 5b which are opposite to the keys 4a and 4b respectively. In case the key 2a is pushed to obtain a TV mode, the keys 4a and 4b function to control the sound volume. Thus ''sound increment'' and ''sound decrement'' are displayed at the matters 5a and 5b. When the keys 2b and 2c are pushed, the corresponding displays are given to the matters 5a and 5b.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control oscillator for remotely controlling a television and other equipment such as a VTR1 teletext receiver.
If the TV is being controlled, the TV function display (H,
When controlling other equipment such as a VTR,
It is an object of the present invention to provide a remote control oscillator that can display all functions using the same display body.

When teletext is put into practical use, VTR, TV, text 2 -
7. Broadcasting - A case can be considered where operation is performed using one remote control oscillator. To specify TV channels, teletext programs, etc., use a common numeric keypad with a common display (0°1.2...
...9), but when using common function keys, the display must be changed. In other words, on a TV, power/volume high, volume low,
Function keys are required for main/sub switching of audio multiplexing, audio mute, etc., and for VTR, function keys are required for rewind, fast forward, play, & i-picture, fast forward, play 2 rewind, play, pause, etc. So stop, resume, conceal, reveal.

Requires function keys such as copy.

The present invention aims to use these function keys as a type of function key when remotely controlling other devices such as an iTV and a VTR, and to enable good display. Examples will be described with reference to the drawings.

As shown in Fig. 1, a switch key 2 for switching the control of a television, VTR, and text multiplex receiver is placed on a housing 1 of a remote control oscillator.
&, 2b, 2o, and a numeric keypad 3a commonly used for the above three, such as switching channels and specifying 9 alternate programs.

+31.3j to 3 and function switch key 4! L, sb, and a liquid crystal display 515 corresponding to the function switching keys 4a, 4b.
b. This function switching key 4a.

4b is a fast forward and rewind key when the key 2bl is pressed to turn on a VTR; in this case, the liquid crystal display 5 is displayed as shown in FIG.
1L, 5bK "Fast forward" and "Rewind" are displayed.If you press key 21L all the way to switch to TV, press function switch key 41.
L and 4b are keys for adjusting the volume, and as shown in FIG. 3, the liquid crystal display 61.degree. 6b displays 1 tone dog" and 6 tone small. When pressing the key 20f to control the teletext receiver, the keys 4a and 4bl-i are used for reveal and conceal, and the LCD display 5a+sb displays "repeat".
and 1 Conceal” will be displayed. Although not shown,
Another pair of function keys and a liquid crystal display are provided for ε NEET and main/sub switching in case of TV, stop and play in case of VTR, and stop and restart in case of teletext. You can provide as many others as necessary.

JP-A-58-156290 (2) It is sufficient to configure the liquid crystal display 51L and 5BLD dot matrix and control it with the MPU as shown in FIG. That is, when the TV input terminal 7a of the input port is set to 1, data to be displayed as shown in FIG. 2 is read from the ROM 9, and the data is supplied from the 1jAM 9 to the liquid crystal drive unit 1o to display characters.

The case where the VTR terminal 7b and teletext terminal 7c are 1 can be considered in the same way.

As mentioned above, since one function key can have multiple functions and the corresponding display can be displayed on the same liquid crystal display, it is useful when remotely controlling many things such as TVs, VTRs, text broadcasts, etc. It allows for clear display.
