Abstract

The method is for display data necessary to operating an appliance at power on a screen. The method comprises the steps of: (A) checking a power on key signal; (B) reading data concerned to time, schedule, channel, volume, and operating mode prior to power off and displaying the data on a screen; (C) setting an OSD timer; (D) checking end of OSD timer; and (E) removing on screen data when a preset OSD time is over.

The present invention relates to a method for displaying information on a power 'on' time for displaying a predetermined time for various information items necessary for operation of the power 'on' in a video reproducing apparatus having an OSD (ON SCREEN DISPLAY) function.

In video playback devices such as TVs and video tape recorders with OSD functions that display information on the screen, when the power is turned on, only the selected channel number is displayed on the screen. The current volume was unknown.

In other words, only the channel number is displayed on the screen when the power is turned on, so the user has to select a display function key of the transmitter in order to know various information required for the set operation.

Therefore, to know various information items from the power 'on', it was necessary to operate another function key of the transmitter, so it was inconvenient to operate the set.

In view of the above, the present invention displays various information items for a predetermined time when the powder is 'on', and then disappears after displaying various information items for a certain time when the 'powder' is turned on. Mute

When described in detail based on the accompanying drawings, the present invention for the purpose of displaying a certain amount of information with the power 'on' as follows.

1 is an implementation circuit diagram of the present invention, in a microcomputer 10 of a television or video tape recorder which receives a key input of a key matrix 5 or a transmitter, the program and data of an internal ROM and a RAM are used to transmit a PLL IC 15 to the PLL IC 15. FIG. The tuning data is sent to allow the tuner 20 to tune the selected channel while the OSD circuitry is used to display the necessary information on the CRT 25.

Such a microcomputer 10 is a microcomputer applied to a television or a video tape recorder, and the peripheral functional blocks of the microcomputer 10 are also general technical contents.

The present invention changes the internal program of the microcomputer 10 as shown in FIG. 3 to display a screen on which information items such as FIG. It is.

Hereinafter, the present invention will be described in detail with reference to the flowchart of FIG.

The microcomputer 10 determines whether the key matrix 5 or the power key is input from the transmitter. If the power key is not input, the microcomputer 10 exits from the program. If the power key is input, the set date (DATE) and time (TIME) , Check the schedule (SCHEDULE).

Here, the date or time is changed by the internal timer if the user has set it before, and the schedule is preset by the user to indicate an appointment or an anniversary on a specific date. .

For example, if the data of Father's birthday is set in advance on the date of birth of the father, the above-described schedule data is displayed on the date of birth so as not to be forgotten.

On the other hand, when the power key is input, the microcomputer 10 recognizes this and performs the flowchart of FIG. 3 while driving a power supply circuit (not shown) to operate the set normally.

When the power key is input, the microcomputer 10 checks the set date, time, and schedule, and determines whether the date is set, and displays the set date when the date is set. After displaying the date, it is judged whether the time is set. If there is no time set, it simply displays the time title. After the time is displayed, it is judged whether the schedule is set. Display the schedule and simply display the schedule title if no schedule is set.

The schedule will not appear here if the date is not set.

After displaying the data set by checking the date, time and schedule when the powder is 'on', the memorized channel checks the volume and operation mode. Is displayed and the above-mentioned contents are not memorized in memory (i.e., when the power code is removed and inserted, and the power key is pressed), the channel, volume, and operation mode are initially displayed (channel = 3. volume = 0. operation mode = TV).

That is, when the power is 'on', the volume, channel, and operation mode before the power 'off' is displayed. When the power is initially on, the channel, the volume, and the operation mode are displayed as the initial state.

When the display of the volume, channel, and operation mode described above is finished, the OSD timer is set and the audio signal is muted, and then the OSD timer is checked for 6 seconds.

When 6 seconds have elapsed by the OSD timer, the OSD text disappears and the audio signal is muted and the program ends.

Here, an example of OSD characters displayed on the CRT 25 based on the flowchart of FIG. 3 is as shown in FIG. 2.

That is, when the power is turned on, the OSD screen as shown in FIG. 2 appears, and the audio signal is muted. When the screen is displayed for a predetermined time (6 seconds), the OSD text disappears while the audio signal mutes. By releasing, it is possible to perform normal operation.

As described above, according to the present invention, in a video playback device having an OSD function, when the power is 'on', various information items necessary for the set operation are displayed with a voice signal mute for a predetermined time, and then OSD character is passed after a predetermined time. In addition to disabling the voice signal mute and allowing normal operation to be performed, the information is turned on with the power 'on' without the need for any other key operation to know the information after the power is turned on. Easy to use set.

Claims (2)

A video reproducing apparatus which recognizes a key input from a microcomputer to control a set drive and displays OSD characters according to the key input, the method comprising: checking a power key input, and if the power key input is checked, the date, time, schedule data, and the last time. Reading the channel, volume, and operation mode status from the memory of the microcomputer and displaying them as OSD characters, setting the OSD timer, checking if the set time of the OSD timer has elapsed, and when the OSD timer has elapsed. A method for displaying information on a power 'on' characterized in that the step of making the OSD characters disappear. According to claim 1, When the power key is pressed, the audio signal is muted together with the OSD text display, and when the timer setting time elapses, the OSD text disappears and the voice signal mute is released. Display 'method.
