Description

TV on timer control method

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

Referring to the accompanying drawings, a method for setting and reproducing an on time of a TV according to the prior art for performing the on time reservation function will be described below.

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

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

When the on time reservation is set, the channel of the broadcast displayed at the on time, the on time time, and the volume are again set 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 screen of the image display apparatus (TV) or remains on. It is maintained (S104).

After the image display apparatus is turned on or off, the controller determines whether the set on time time has elapsed (S105). If the set on time has not elapsed, the video display device maintains the current screen state, and if the on time has elapsed, the video display device detects the screen state of the current video display device (S106).

If the screen of the image display apparatus is turned on in the step S106, the channel is switched so that the currently received broadcast channel is the same as the channel set in the step S102 (S107).

At this time, if the currently received broadcast channel is the same as the preset channel, there is no change in the screen state.

On the other hand, if the screen of the image display device is off, the screen is turned on (S108), the channel is switched so that the current broadcast channel and the preset broadcast channel are the same, and then the audio / video data of the preset broadcast channel is read. The display device displays the image on the image display device at the set intensity (S109).

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 before, 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 the on-time control method of the TV according to the related art, when the on-time function is reserved, when the TV is turned on at the reserved time, that is, when the TV of the same channel as the channel set at the reserved time is being watched, the change of the screen state is changed. Since the on-time function cannot be properly performed, there is a problem in that the user cannot determine whether the scheduled time has come as well as notifying the user even when the time is reserved by the on-timer.

In addition, since the intensity of the volume is constantly set, there is a problem in that the on-timer reservation time cannot be determined by the constant intensity of the volume if the user falls asleep or leaves the room while the TV screen is turned on. .

Accordingly, the present invention has been made to solve the problems of the prior art, and provides an on-timer control method of a TV for adjusting the intensity of the volume depending on the screen state of the image display device and the user's viewing at the time of on-time. The purpose is.

In the on-timer control method of a TV according to the present invention, in the on-timer control method of a TV having an on-timer reservation key, setting the on-time time, channel, and volume intensity by the on-timer reservation key; It is characterized by the step of detecting the screen state of the TV when the time reaches, checking the user's TV viewing according to the screen state, and adjusting the intensity of the volume according to the TV viewing.

Hereinafter, a preferred embodiment of the on-timer control method of the 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 on-timer control of a TV according to the present invention.

Referring to FIG. 2, the configuration thereof includes: a tuner 20 for tuning a broadcast signal received through an antenna ANT to a set channel, a detector 21 for demodulating the tuned broadcast signal, and demodulation. An audio signal processor 22 for acoustically processing the audio signal of the broadcast signal, a first amplifier 24 for a predetermined level amplification to output the audio signal through the speaker 23, and a demodulated broadcast signal. A video signal processor 25 for processing a video signal, a second amplifier 27 for a predetermined level of amplification to output the processed video signal through the monitor 26, and on-time of the monitor 26. A controller 28 for outputting a character generation control signal and a volume control signal according to the on / off state, an OSD character generation unit 29 for generating OSD characters according to the character generation control signal, and the generated OSD character signal and image processing Second amplification by mixing the video signals It consists of a mixer 30, which output (27).

Referring to the operation of the on timer control apparatus of the TV according to the present invention having such a configuration as follows.

First, the on time time, channel, and volume are set using the on time reservation function keys.

When the set on time is reached, the controller 28 detects an on / off state of the monitor 26 and outputs a control signal accordingly.

In addition, the OSD character generator 29 generates an OSD character according to the control signal of the controller 28, and the mixer 30 mixes the broadcast video signal processed by the video signal processor 25 and the generated OSD character. And output to the second amplifier 27.

The second amplifier 27 receives two mixed signals and amplifies a predetermined level to output the same on the monitor 26.

The controller 28 adjusts the volume intensity by outputting a control signal to the speaker 23 according to a user's command input for the OSD character output on the monitor 26.

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 key is selected by an operation of a remote controller while the power of the image display device (TV) is turned on (S200). On timer reservation function is set (S201).

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

The on-time time and the intensity of the channel and the volume set as described above are stored in a predetermined memory (not shown) in the control unit (not shown) and counting time (S203).

In addition, the user may turn off or leave the screen of the image display apparatus TV in operation S204.

Subsequently, the controller continuously detects whether the on time time has been reached (S205). If the on time time has not been reached, the controller continuously maintains the previous on or off screen state of the image display apparatus.

On the other hand, if the time has elapsed and the on time time has been reached, the monitor 26 state of the current video display device is detected (S206). If the monitor 26 is in the ON state, the OSD character generating unit 29 controls the controller ( The OSD character is generated under the control of the control unit 28 and the OSD (On Screen Display) character is output to the predetermined area on the monitor 26, "Please input the response key if you are watching the TV." ).

Detecting whether the response key is input to the OSD characters displayed on the monitor 26 (S208) When the user inputs the response key to the OSD characters (S208) and maintains the strength of the volume set in the above step (S202) ( S209).

On the other hand, if there is no input of the response key for OSD characters, the user determines that the user has fallen asleep or has left the video display device on, so that the controller 28 controls the speaker 0 to set the intensity of the initially set volume. It raises the level to recognize the timer reservation time for the user who has fallen asleep or away (S210).

In addition, if the screen of the image display device is in an OFF state in the above step (S206), turn on the screen of the image display device (S211), and detects whether the currently received channel is an initially set channel and is initially set on. The on timer control is completed by switching to the time channel (S212).

Therefore, when the on-timer control method of the TV according to the present invention is compared with the prior art, when the on-screen time is reached when the on-timer is reserved, that is, the user is watching TV, In the conventional case, when a reserved time arrives, the channel is automatically switched, or when watching the same channel as the reserved channel, there is no change and it is not possible to determine whether the user is on timer time.

In addition, the on timer function not only wakes up to wake up the user, but also performs a function of obtaining information of a certain time or not forgetting an appointment time. In the related art, an on timer function is provided when a TV screen is on. It did not perform properly.

Therefore, the present invention is to turn on the TV in the reserved channel in the same manner as the conventional method when the screen is turned off when the scheduled time is reached to perform this function faithfully, the user when watching TV Detects whether you fall asleep while watching TV or if you are away for a while and adjusts the volume's intensity accordingly to let you know it's scheduled.

The on-timer control method of the TV according to the present invention detects a case in which the user falls asleep or has left the TV screen on while the TV screen is turned on, thereby raising the volume level accordingly, to wake up the user who has fallen asleep. Inform the user of the timer reservation time when he is away.

Therefore, there is an effect that the on timer function can be accurately performed even if the user falls asleep while the screen of the TV is on or the screen is turned on.

In addition, the on-timer control method according to the present invention has the effect of further improving the conventional on-timer function.
