METHOD AND APPARATUS FOR DISPLAYING AUDITION-TIME OF A TV

摘要

The present invention relates to a method and a device for displaying a viewing time of a TV, and a key matrix for recognizing a user's option by adding a viewing time key switch and a time display / sound selection key switch to an existing key switch including a power key switch. And a microprocessor for controlling the overall operation while receiving a user's option according to which key switch of the key matrix is on or up, and storing information on the processing order and conditions of the microprocessor. A ROM for outputting according to the request of a microprocessor, a timer for counting the number of pulses generated from the crystal oscillator of the microprocessor and informing the microprocessor of time information, and storing and outputting information data required by the microprocessor. RAM and said microprocessor On Screen Display Intergrated Circuit (OSD) for displaying characters by outputting image control signals to the monitor according to data signals, strobe signals, and click signals from, and speakers through the audio output signals from the microprocessor. The user can watch by configuring a voice IC for outputting the viewing time as a voice and a relay driver for turning on / off a relay for supplying power supplied from the outside to the internal driving power according to a control signal from the microprocessor. If you set the desired viewing time with the time keyswitch, the microprocessor displays the elapsed viewing time as text on the monitor or by voice through the speaker according to the user's time display / sound selection. It was made to be.
