Description

TV on timer control method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to TV (hereinafter referred to as TV), and more particularly to a method for controlling an on timer of a TV for improving the efficiency of an on timer reservation function.

In modern society, as the early commute system expands, it is not uncommon for people to go to work early in the morning. Therefore, in most cases, a user wakes up in the morning by using an alarm clock for early weather or by using an on-time reservation function of a TV to which the function is added according to the development of TV technology.

In addition, the on timer function of the TV may be used not only to wake up the user to wake up as described above, but also to obtain information provided from a TV broadcast or to forget an appointment time. . Therefore, a function for notifying the user when the scheduled time comes is the on timer function.

The on timer control method of the TV using the on timer reservation function of the TV according to the related art will be described with reference to the accompanying drawings.

1 is a flowchart for performing on timer setting and playback of a TV according to the prior art.

First, when the user wants to set the on timer function, the on time reservation function is set by selecting the on timer reservation key using a remote controller while the image display device (TV) is on (S100). (S101).

When the on timer reservation is set, the channel of the broadcast displayed on the on timer operation, the on time time and the intensity of the volume are set again using the remote controller (S102).

The channel, on-time time, and volume intensity set in this way are stored in a predetermined memory (not shown) in the controller (not shown) (S103), and the user turns off the display screen of the image display apparatus (TV) (S104). ).

After the image display apparatus is turned off, the controller determines whether the set on time time has elapsed (S105). If the on time has not been set, the video display device continues to turn off the screen. If the on time has elapsed, it is determined whether the broadcast channel being received is the same channel as the on time channel set in step S102. It is determined again (S106).

If the currently received broadcast channel is not the same as the set channel, the channel is switched to the preset channel according to the channel switching control signal of the controller (S107).

On the contrary, if the broadcast channel currently being received and the preset broadcast channel are the same broadcast channel, the screen of the video display device is turned on and at the same time the audio / video data of the preset broadcast channel is set to the intensity of the preset volume. Display on (S108).

In this case, the volume intensity and the channel do not need to be set by the user. Because when the on-time time is set, the strength of the channel and volume when the video display device is turned off is memorized, and the audio / video data of the channel is stored at the on-time setting time according to the strength of the stored channel and volume. Because it is displayed.

In addition, referring to another method of setting and reproducing on-time of a conventional TV, as described above, a user sets on-time time and intensity of a channel and a volume by using an on-time reservation key.

Subsequently, when the preset on time is reached, the broadcast audio / video data being received is displayed according to the strength of the preset channel and volume.

At this time, if the stop key is not input within a predetermined time period, the strength of the preset volume is increased according to the volume up (UP) control signal of the controller.

This method is for the case that the user cannot wake up because the user cannot hear the audio data played during the on time due to the low intensity of the preset volume during the on time.

In the conventional method of controlling the on-timer of a TV, when the on-time function is reserved, the on-time function cannot be properly performed when the TV is turned on at the reserved time, that is, when the user is watching the TV at the reserved time. There is a problem in that the user cannot determine whether the scheduled time is reached because the timer cannot be informed even if the time is on time.

Accordingly, the present invention has been made to solve various problems according to the prior art, and when the on time time reserved by the user is reached, the on / off state of the TV power is determined and the on timer operation is informed accordingly. The present invention provides a method for controlling a timer.

In the on-timer control method of the TV according to the present invention, the on-timer control method of a TV with a monitor, comprising the steps of setting the on time time and channel, detecting the screen state of the monitor when the set on time time is reached; It is characterized by including the step of adjusting the screen output of the set channel by using the PIP function according to the detected monitor screen state.

Hereinafter, a preferred embodiment of a method for controlling an on timer of a TV according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram illustrating an apparatus for controlling an on timer of a TV according to the present invention, and FIG. 3 is a flowchart for performing an on timer control according to the present invention.

Referring to FIG. 2, the configuration thereof includes: a tuner 20 for tuning the broadcast signal received through the antenna ANT to match a set channel, a detector 21 for demodulating the tuned broadcast signal, and demodulation. A video signal processor 21 for image-processing a video signal among the broadcast signals, a reproduction amplifier 23 for amplifying the image-processed video signal to a predetermined level, and outputting the video signal to the monitor 22; Control unit 24 for determining an on / off state of the control unit and outputting a control signal according to the control signal, and processing and outputting a broadcast signal tuned by the tuner 20 by PIP (Picture In Picture) processing by the control signal of the control unit 24. PIP signal processing section 25, and a mixer 26 for mixing the image processing broadcast signal and the PIP signal to output to the reproduction amplifier 23.

Referring to the operation of the on-timer control device according to the present invention configured as described above are as follows.

First, the strength of the on time channel and the volume is set using the on time reservation function key.

When the set time is reached, the controller 24 determines whether the monitor 22 of the current TV is on or off and outputs a control signal accordingly.

The PIP signal processor 25 processes the video signal of the channel set by the control signal of the controller 24, and the mixer 26 mixes the currently received video signal with the PIP signal to the reproduction amplifier 23. Output

The reproduction amplifier 23 amplifies the mixed video signal and the PIP signal to a predetermined level and simultaneously outputs them on the monitor 22.

That is, the PIP signal is displayed in a predetermined region of the broadcast video signal currently received.

When described in more detail with reference to Figure 3 on timer control of the TV according to the present invention configured and operated as follows.

First, when the user wants to set the on timer reservation function, the on timer reservation is selected by selecting an on timer reservation key using a remote controller while the video display device is turned on (S200). The function is set (S201).

When the on timer reservation is set, the on time time and the channel are selected and set again by using the remote controller (S202).

The channel and the on-time time set as described above are stored in a predetermined memory (not shown) in the control unit (not shown) and the time is counted simultaneously (S203). The user may then turn off or leave the screen of the image display apparatus TV.

After the image display apparatus TV is turned on or off, the controller continuously determines whether the set on time time has elapsed (S204).

If the on time time set in step S204 is not reached, the scheduled on time time and the current time are continuously checked, and when the on time time is reached, the TV screen state is determined (S205).

If the TV screen is not in the ON state, by turning on the TV screen and switching the TV broadcast channel to the reserved channel (S206), the on timer control of the TV is completed.

On the other hand, when the current TV screen is on in the above step (S205), the video signal of the channel set by the PIP signal processor 25 is PIP signal processing and displayed on a portion of the current TV screen (S207).

In other words, the PIP (Picture In Picture) function is used to show the screen of a channel set to a small size in a certain area of the current screen.

Subsequently, when the video signal of the channel set by the PIP function is being displayed, the user detects whether a channel switching signal for switching channels is input because the reserved channel is not the same as the TV broadcast channel currently being played (S208). ).

If a channel change signal is input according to the channel change key of the remote controller by the user (S209), if the channel change signal is not input, the display screen of the reserved channel by the PIP function is turned off after a certain time ( S210) Complete the on timer control while maintaining the current channel.
