KR970009238A - Automatic time setting method of video equipment - Google Patents

Abstract

According to the present invention, a user can set a channel or time adjustment amount for automatic time setting so that an ATS operation error can be reduced in two or more channel adjacent areas or astigmatism areas having different time zones. It relates to a time setting method, characterized in that the first step of checking whether a condition for performing the ATS function is selected, and if the ATS execution condition is selected in the first step is selected by selecting the corresponding channel A second step of reading an image signal and determining whether the clock data exists in the VBI section of the video signal, and displaying a message according to the presence of the clock data on the screen by the OSD; and the clock data displayed in the second step. If the user sets the difference with the current time, the clock data is corrected by the difference and matched with the current time. In the third step, and if the ATS execution condition is not selected in the first step, the fourth step is performed by sequentially tuning the lower channel to the channel where the clock data exists and reading the clock data of the corresponding channel and storing it in the memory.

Automatic time setting method of video equipment

Since this is an open matter, no full text was included.

2 is a block diagram of a high frequency reception circuit for implementing the automatic time setting method according to the present invention.

Claims (3)

A first step of checking whether a condition for performing the ATS function is selected; and if an ATS execution condition is selected in the first step, the selected channel is tuned to read a video signal, and clock data is stored in the VBI section of the video signal. In the second step of determining whether there is a clock data and displaying the message according to the presence or absence of the clock data on the screen, and when the user sets the difference value between the clock data displayed in the second step and the current time, The third step of correcting the clock data to match the current time and storing it in the memory, and if the ATS execution condition is not selected in the first step, selects a channel from the lower channel to the channel in which the clock data exists, and then clocks the corresponding channel. And a fourth step of reading data and storing the data in a memory. The method of claim 1, wherein the first step includes checking whether the ATS execution key is selected from the outside (S10) and checking whether a channel for performing the ATS function is selected within a predetermined time after the ATS execution key is input. The automatic time setting method of the video device, characterized in that the step (S11 ~ S13). The method of claim 1, wherein the second step includes tuning the channel set by the ATS channel input key (S14), reading the clock data on the VBI section of the video signal of the tuned channel (S15); Determining whether the clock data exists in the tuned channel (S16); and if the clock data does not exist in the tuned channel, displaying a message indicating that there is no clock data on the screen and then checking the ATS channel input key. Returning to step S17, and if the clock data exists in the tuned channel, displaying the read clock data in OSD on the screen together with the tuned channel number (S18), and the clock data displayed on the screen and the current time. The step of waiting for the user to set the difference value (S19) characterized in that the automatic time setting method of the video device. ※ Note: The disclosure is based on the initial application.
