A storage and display method of using infomation for television.

The television receives the radio wave transmitted from the broadcasting station, demodulates the color composite signal, separates the luminance signal from the color signal, displays them on the CRT, demodulates and reproduces the audio, and outputs them to the speaker. If you select the frequency of the desired channel in the tuner and make the same intermediate frequency in the next intermediate frequency amplifier, the image detection results in the color composite signal. The color composite signal is separated by Y and C using a comb filter, and the Y signal is amplified by the delay circuit by the time delay when demodulating the C signal, and then applied to the cathode of the CRT and the RY and GY of the C signal. , BY controls the C, R, G, and B electron beams to reproduce a wide range of colors in each pixel unit. CRT's high-pressure 22KV accurately guides the electron beam to the screen. The audio is separated from the video intermediate frequency and amplified by the audio intermediate frequency, then FM detected by the demodulator, separated into the main signal and the sub signal, and subtracted or added through the matrix circuit to obtain the L and R of the stereo and the main signal in two languages. Alternatively, the negative signal is output to the L and R speakers as they are.

Such a television has recently been developed to be used in a multi-environment by being connected to a video player such as a VCR, an AV device, a personal computer, etc. in a simple function of receiving and watching a broadcast signal transmitted from a broadcasting station. In particular, the use of MICOM and EEPROM, which enables to record and reproduce brief information on a TV, and the development of OSD (On Screen Display) implementation technology are becoming more diverse.

However, the conventional OSD television as described above can display only the information on the function of the television itself recorded at the time of shipment by the manufacturer of the television, so there is a problem in that the utilization of the user cannot be increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the conventional television, and an object of the present invention is to provide information on the usage environment of various televisions so that the user can check the usage status of the television on an OSD screen. It is to provide a method of storing and confirming the usage environment of a television which can be stored by the control and storage function of YPIROM and later displayed by the storage information on the OSD screen when the user wants to check the stored usage environment of the television. .
