Abstract

The present invention relates to a method of turning on the reservation of a television. In particular, a television having a PIP function displays a reserved on-channel on a sub-screen by operating the PIP function if it is not in the PIP operation state at the time of the reservation-on time. If the screen displays a message indicating that the reservation is on, the main or sub-screen is switched to the reservation channel, and when the reservation on time is reached on the television without the PIP function, a message indicating that the reservation is on is displayed. After that, by switching the viewing screen to the reserved channel, the viewing screen is suddenly switched to the reserved channel to prevent the viewer from being embarrassed. In addition, when the scheduled on operation is performed while the power of the television is off, the key signal inputted to the television for a specified time is not checked and the television is automatically turned off if no television is present. It prevents unnecessary power waste by preventing the operating state by itself.

Description

How to control reservation on of television

The present invention relates to a reservation on control method of a television which reserves a time for turning on a television and a channel in advance and automatically turns on the television to a reserved channel when the reserved time comes.

As the spread of television becomes more common, services for viewers are also diversifying. One of them is the reservation on method for convenience to the viewer. That is, a service that automatically reserves the TV on time and a channel, and then automatically turns on the television to the reserved channel when the scheduled time comes, which also serves as a wake-up call in the morning, and also enables viewers to select specific channels in a specific time zone. It also prevents you from forgetting when you want to watch it. At this time, the television must be at least stand-by for the microcomputer to operate. When the off time is reserved, the television is automatically turned off when the off time is reserved.

Fig. 1 is a flowchart of this conventional reservation on method, which checks whether the reservation on time is set by the viewer (step 101). If it is determined in step 101 that the reservation is on, it is checked whether the television is turned on (step 102).

If the television is turned on in step 102, the power remains on and the screen is switched to the reserved channel (step 103). The state is maintained until the scheduled off time or until the channel is manually switched or turned off by the viewer (step 105).

If the television is turned off in step 102, the power is turned on to display the screen with the reserved channel (step 104). The state is maintained until the scheduled off time or until the channel is manually switched or turned off by the viewer (step 105).

However, in the conventional reservation on method, reservation on is operated while a television is being watched, and thus a sudden change of a channel may cause a viewer to be confused. This may happen if another person in the family is watching reservations and the viewing is actually performed at that time by someone who has not set the reservations on, or if the user forgets to turn on the reservations on.

In addition, if the reservation on is operated in the absence of forgetting or not knowing that the reservation is turned on, the television alone operates to cause a waste of power.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a picture on picture (PIP) function capable of simultaneously displaying a main / sub picture and to perform a reservation on on a sub picture. To provide a method of controlling the reservation on.

Another object of the present invention is to provide a reservation on control method of a television that displays a guide message informing of reservation on when the reservation on time comes.

Still another object of the present invention is to provide a method of controlling a reservation on of a television which automatically turns off the television when there is no response key input for a designated time when the television is powered on and the reservation on is operated.

A feature of the reservation on control method of a television according to the present invention for achieving the above object is to display a reservation channel by operating the PIP function when the PIP function is not in the PIP operation state at the reservation on time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram illustrating a general circuit of a television for performing the reservation on control method of the television according to the present invention.

Referring to FIG. 2, the microcomputer 20 performs reservation on, PIP, power, and image signal processing by controlling a series of operations for each functional block. The key matrix 21 notifies the microcomputer 20 when the reservation on / off, channel switching, PIP operation, etc. are selected by the viewer. The power supply unit 22 supplies power to each signal processing unit under the control of the microcomputer 20. In addition, the power supply unit 22 automatically turns on / off the power of the television under the control of the microcomputer 20 even when the scheduled on / off function is performed.

The first tuner 23 tunes the first image signal to convert it to an intermediate frequency (IF), and the first image signal processor 24 outputs the intermediate frequency signal output from the first tuner 23. After amplification, the signal is separated into a luminance signal and a color signal. The second tuner 25 tunes the second image signal and converts the second image signal to an intermediate frequency. The second image signal processor 26 amplifies the intermediate frequency signal output from the second tuner 25 and then outputs a luminance signal and a color. Separate by signal. Both the first and second video signals may be broadcast signals transmitted from broadcasting stations, and one broadcast signal may be a signal input through an external terminal such as a video cassette recorder (VCR). In addition, the first and second video signals may be signals of the same channel or signals of different channels.

At this time, the main / sub picture signal processor 27 synthesizes the signals output from the first and second video signal processors 24 and 26 into a main picture signal and a sub picture signal to deflect the color demodulator 28. The signal is output to the signal processor 29. The color demodulator 28 demodulates the output of the main / sub picture signal processor 27 into R, G, and B color signals under the control of the microcomputer 20, and outputs the demodulated signal to the CRT 30, and outputs a deflection signal processor ( 29 processes the output of the main / sub picture signal processing unit 27 into a deflection signal under the control of the microcomputer 20 and then outputs the deflection yoke (DY) of the CRT 30. The CRT 30 luminance modulates the R, G, and B color signals output from the color demodulator 28 to form a picture element, and the deflection signal processor 29 assembles the pixels just like the transmitting side. The original image sent from the sender is reproduced on the screen.

At this time, if the PIP function is selected and the first video signal is a signal of the main screen, and the second video signal is a signal of the sub-screen, the first video signal is displayed on the main screen and the second video signal is displayed on the sub-screen by signal processing. Is displayed.

For example, when the viewer selects KBS1 as the main picture signal and MBC as the sub picture signal, the microcomputer 20 outputs a channel selection signal for selecting KBS1 as the first tuner 23 and the second tuner. At 25, a channel selection signal for selecting MBC is output. Accordingly, the first tuner 23 tunes a frequency corresponding to KBS1 to an intermediate frequency, and the second tuner 25 tunes a frequency corresponding to MBC to an intermediate frequency. When the outputs of the first and second tuners 23 and 25 pass through the first and second image signal processing units 24 and 26 and the main / sub picture signal processing unit 27, respectively, the main screen of the television is displayed. KBS1 is displayed and MBC is displayed on the sub-screen.

At this time, whether the main screen and the sub-screen switching and the sub-screen is received to send the relevant data from the microcomputer 20 to the main / sub-screen signal processing unit 27 to select.

3 is a flowchart of a reservation on control method according to the present invention for performing a reservation on by using the control of the microcomputer 20 and the PIP function.

That is, it is checked whether or not the reservation on time set by the viewer (step 301). If it is determined in step 301 that the reservation is on, it is checked whether the television is on (step 302).

If the television is turned on in step 302, it is determined whether the PIP screen is in operation (step 303). If the PIP screen is operating in step 303, that is, the main screen and the sub-screen are being viewed simultaneously, a message indicating reservation ON is displayed on the screen so that the viewer recognizes this and does not panic even if the channel is switched (step 304). ). If the main (or sub) screen set to the reserved on screen is the same as the reserved channel, it is kept as it is, and if it is wrong, it is switched to the reserved channel (step 305). Here, the viewer may set one of the main screen and the sub screen as the reserved on channel screen through the microcomputer 20, and may switch the main screen and the sub screen. The reserved channel state is then maintained until a scheduled off time or manually switched by the viewer or powered off (step 306).

On the other hand, if it is determined in step 303 that the PIP screen is not in the operating state, it is checked whether the current television is a television having a PIP function (step 307). If it is determined in step 307 that the television does not have a PIP function, a guide message indicating that reservation ON is operated is displayed on the screen currently being viewed (step 304). Switch to step 305. The state is then maintained until the scheduled off time or manually switched by the viewer or powered off (step 306).

If it is determined in step 307 that the television has a PIP function, the PIP is operated to display the reserved on channel on the sub-screen (step 308). The reserved channel state is maintained on the sub-screen until the reserved off time is reached or until the channel is manually switched or turned off by the viewer (step 306). At this time, main / sub picture switching is possible by the selection of the viewer.

If the television is turned off in step 302, power is supplied through the power supply unit 22 to turn on the television and display the screen on the reserved channel (step 309). Then, it is checked whether an arbitrary key signal is input until the predetermined time passes by the microcomputer 20 (step 310). That is, it is determined whether or not the viewer is watching the television by using the key signal input until the designated time. In this case, a guide message for inputting an arbitrary key may be displayed on the screen so that the viewer recognizes it. Therefore, if there is any key response before the time specified in step 310 has elapsed, it is determined that there is a person watching television and the channel is switched or powered off manually until the scheduled off time or by the viewer. The reserved channel state is maintained until (step 306).

On the other hand, if it is determined that there is no key response until the time specified in step 310 has elapsed, it is determined that there is no person watching the television or is absent, and returns to the state before the reservation is turned on (step 311). That is, since the reservation on operation was performed while the television was turned off, the television was turned off via the power supply unit 22.

As described above, according to the method of controlling the reservation on time of the television according to the present invention, if the television having the PIP function is not in the PIP operation state at the reservation on time, the PIP screen is operated to display the reservation on channel and simultaneously view the main / sub picture. In the PIP mode, the display shows the reservation message on the screen and then displays the reservation channel on the main or sub-screen set as the reservation on screen to prevent the viewer from being embarrassed. do.

In addition, when a scheduled on time is reached on a television without a PIP function, a screen message is displayed on the screen that is being watched and then the watch screen is switched to the reserved channel so that the screen is suddenly switched to the reserved channel. To prevent embarrassment.

If the scheduled on operation is performed while the power of the television is turned off, a key signal input to the television for a specified time is checked and the television is automatically turned off if no television signal is present. It prevents unnecessary power waste by preventing the operating state by itself.
