The present invention relates to a TV. More specifically, a memory element storing a meaning of a Korean word or an English word is attached, and when an unknown word appears while watching TV, a word is input by using a remote controller. It is about a TV with a built-in dictionary function.

In order to acquire a foreign language, especially English, various methods of learning are used, such as attending a school, listening to a tape, or watching a VCR tape, and it is well known that watching English-language TV programs helps learning. Conventionally, when a foreign word, especially English words, whose meaning is unknown while watching an English broadcast, comes out, a dictionary is searched to grasp their meaning.

However, since the broadcasting continues without time delay, a large amount of contents are missed while the time is spent searching the dictionary to determine the meaning of an unknown word and the learning efficiency is reduced. Conventionally, electronic dictionaries are sometimes used, but these are expensive and have not yet been popularized.

The present invention was devised to solve such a problem, and an object of the present invention is to display the meaning of a word by simply entering a word with a remote controller when an unknown word appears while watching TV broadcast in English. It is to provide a dictionary function.

Another object of the present invention is to provide a TV having an efficient function for language learning.

In order to achieve the above object, a TV having a built-in dictionary function of the present invention includes a remote control device for controlling a function of a TV at a remote location, a receiver for receiving a signal radiated from the remote control device, and a control signal output from the receiver.

In addition, reference numeral 8 is a remote control device for generating a variety of commands, such as selecting a channel desired by the viewer or switching the TV / VTR and external AV device (not shown), and 9 is an infrared signal generated from the remote control device (8) Is a receiving unit for converting into an electric code signal, and 11 is a microprocessor for controlling the entire circuit in accordance with the remote control signal generated from the remote control device 8.

Reference numeral 13 denotes a PWM signal generator for generating a predetermined pulse width modulation (PWM) signal in accordance with a control signal output from the microprocessor 11, and reference numeral 14 denotes a predetermined level signal by integrating the generated PWM signal. It is an integrated circuit to generate.

Reference numeral 16 is an adder for adding a voltage signal applied from the integrating circuit 14 and a voltage signal applied from an AFT (Auto Fine Tuning) circuit 15, which will be described later, and 17 is the adder 16 as a local oscillating circuit. By generating a predetermined frequency corresponding to the voltage level signal applied through the) and outputs it to the mixer (3) to tune to the broadcasting station.

On the other hand, the AFT circuit 15 is an automatic microcircuit circuit, which is provided for accurate tuning operation. In the TV, the magnitude of the input signal received through the antenna 1 varies due to the strength or fluctuation of the received signal, and reference numeral 18 is based on the level of the video signal detected by the image detector 7. By controlling the amplification degree of the above-described RF amplifier and IF amplifier, it is an AGC (Auto Gain Control) which controls the video signal output level output from the image detector 7 constantly.

Reference numeral 21 denotes a voice processing unit such as bass, treble and volume according to a control signal from the microprocessor 11 for the voice signal output from the voice detector 6, and 22 denotes a voice processing unit 21. An audio amplifier amplifies the processed audio signal and outputs it to the speaker.

Reference numeral 23 denotes a color, tint, brightness, etc. according to a control signal from the microprocessor 11 with respect to an image signal output from the image detector 7.

According to the present invention, as shown in FIG. 2, a ROM 26 having dictionary data embedded therein is connected to the microprocessor 11. The ROM may include an English word meaning, a Korean word meaning, or another language (for example, French, Spanish, etc.). In particular, it will be readily appreciated that the pre-capacity can be greatly expanded according to the storage capacity of the ROM 26.

When a word for which you want to know the meaning is input in the dictionary mode, the microprocessor 11 reads the same word as the input word from the memory stored in the ROM 10 and displays it on the screen.

3 is a plan view of the remote control device 8 in which specific characters are assigned to function keys for inputting words into the microprocessor 11 embedded in the TV. As shown, a pre-mode changeover switch 32 is provided adjacent to the power switch 31.

The dictionary mode changeover switch 32 may use a slide switch type switch, and depending on the switching state, the function key of the remote control device 8 is operated as a function key for TV control or a character input key for dictionary search, which is an original function. .

If an unknown word appears while watching a TV broadcast, the dictionary mode switching switch 32 installed in the remote control device 8 is immediately switched to enter the dictionary mode.

In such a state, when the letters constituting the word are pressed in order, the microprocessor 11 outputs a signal to the OSD generator 12 to correspond to the input letters. The OSD generator 12 generates a character generated by the control signal. The generated text signal passes through the mixer 24 and the CRT driver 25 to be displayed on the CRT.

If a typo is generated during character entry, you can correct it using the arrow keys or other assigned function keys. When the character is completely input, press the completion key installed in the remote control device (8).

When a signal is input that the character input is completed, the microprocessor 11 searches for the word stored in the ROM 26 based on the entered word. When the word is found, the microprocessor 11 reads the meaning of the stored word and outputs a control signal to the OSD generator 12 to generate a character corresponding to the word.

The OSD generator 12 generates and outputs a character corresponding to the control signal, and the output signal is displayed on the CRT through the mixer 24 and the CRT driver 25. The meaning of the words displayed on the screen for a certain period of time disappears and the TV performs normal broadcast operation.
