In step S1 of FIG. 2, it is determined whether the main power supply of the television is on. In step S1, when the main power supply of the television is on, it is determined whether the television is in the off state. If the television is in the off state in step S2, it is determined in step S3 whether the on-time reservation mode is on.

That is, when the main power of the television is on and the television is in the off state, the viewer selects the main menu from the control unit and selects the on time reservation mode of the submenu, or sets the on time reservation mode of the remote controller. It is determined whether the on-time reservation mode is set by operating the key for setting, that is, whether the on-time reservation mode is on.

In step S3, if the on-time reservation mode is on, it is determined whether the current time counted in step S4 is the reserved on-time, and if the counted current time is not the reserved on-time, step S4 is performed. Repeat it.

That is, when the on-time reservation mode is on, the controller determines whether the current time counted by the timer is the on-time reserved by the viewer stored in the memory. The determination of whether the current time counted through the reserved on-time stored in the memory is repeated.

If the current time counted in step S4 is the reserved on time, the television is turned on in the reserved on channel in step S5.

That is, when the counted current time is the reserved on-time, the control unit outputs a control signal for turning on the television to the on-channel reserved by the viewer stored in the memory, and the tuner outputs the control signal by the viewer by the control signal of the control unit. By tuning the reserved on-channel, the reserved on-channel is displayed on the CRT through the image processing unit so that the television is turned on.

When the television is turned on with the reserved on-channel in step S5, when the main power source of the television is not turned on in step S1, when the television is not turned off in step S2, and step S3. If the on-time reservation mode is not in the on state, then in step S6, it is determined whether the main power of the television is in the off state, and when the main power of the television is not in the off state, the process returns to step S2. When the main power source is in the off state, the operation of the television is terminated.

That is, when the television is turned on with the reserved on-channel, when the main power of the television is not turned on, when the television is not turned off, and when the on-time reservation mode is not turned on, the control unit then turns on the main power of the television. If the main power source of the television is not in the off state by determining whether it is in the off state, it is determined whether the television is in the off state and performs the operation accordingly, and when the main power source of the television is in the off state, the operation of the television is terminated by the controller. Will be.

However, in the conventional television configured and performed as described above, in the on-time reservation mode, the television is turned on to the on-channel reserved by the viewer at the on-time reserved by the viewer so that the reserved on-channel does not have a broadcast signal. If the volume is low, there is a problem in that there is no broadcast signal or the television is turned on with a low volume channel.

Therefore, the present invention is to solve this problem, in the on-time reservation mode in the initial channel of the pre-stored channel on the reserved on-time, after switching on the TV to the last channel of the pre-stored channel by a predetermined time by a predetermined channel It is an object of the present invention to provide a method for controlling the on-time reservation mode of a television to prevent the television from being turned on by a channel having no broadcast signal or a low volume in the on-time reservation mode.

In step S11 of FIG. 4, it is determined whether the main power supply of the television is on. In step S11, if the main power supply of the television is on, it is determined whether the television is in the off state in step S12. If the television is in the off state in step S12, it is determined in step S13 whether the on-time reservation mode is on.

That is, when the main power of the television is on and the television is in the off state, the viewer selects the main menu from the control unit and selects the on time reservation mode of the submenu, or sets the on time reservation mode of the remote controller. It is determined whether the on-time reservation mode is set by operating the key for setting, that is, whether the on-time reservation mode is on.

In step S13, if the on-time reservation mode is on, it is determined whether the current time counted in step S14 is the reserved on-time, and if the current time counted is not the reserved on-time, step S14 is performed. Repeat it.

That is, when the on-time reservation mode is on, the controller determines whether the current time counted by the timer is the on-time reserved by the viewer stored in the memory. The determination of whether the current time counted through the reserved on-time stored in the memory is repeated.

If the current time counted in step S14 is the reserved on time, the television is turned on to the initial channel of the pre-stored channel in step S15.

That is, when the counted current time is the reserved on time, the controller outputs a control signal for turning on the television to the initial channel of the channel pre-stored in the memory, and the tuner initializes the channel pre-stored in the memory by the control signal of the controller. By tuning the channel, the initial channel of the channel pre-stored in the CRT is displayed through the image processing unit so that the television is turned on.

After the TV is turned on as the initial channel of the pre-stored channel in the step S15, the pre-stored channel is displayed in the step S16 for a predetermined time, and in the step S16 after the pre-stored channel is displayed for the predetermined time in the step S17. It is determined whether the displayed pre-stored channel is the last channel of the pre-stored channel.

That is, after the television is turned on as the initial channel of the pre-stored channel, the control unit displays the pre-stored channel for a predetermined time and determines whether the pre-stored channel displayed on the CRT is the last channel of the pre-stored channel in the memory.

If the previously stored channel displayed in step S17 is not the last channel of the previously stored channel, the process returns to step S16 after switching to the next previously stored channel in step S18.

That is, when the displayed pre-stored channel is not the last channel of the pre-stored channel, the control unit switches to the next pre-stored channel of the memory, and then outputs a control signal for displaying the next stored channel after switching, and the tuner The next pre-stored channel of the memory is tuned to the next pre-stored channel by the control signal, and the next pre-stored channel is displayed on the CRT by the image processor for a predetermined time.

When the pre-stored channel displayed in the step S17 is the last channel of the pre-stored channel, when the main power of the television is not turned on in step S11, when the television is not turned off in step S12, and If the on-time reservation mode is not on in step S13, it is subsequently determined whether the main power of the television is off in step S19, and when the main power of the television is not off, the process returns to step S12. On the other hand, when the main power source of the television is in the off state, the operation of the television is terminated.

That is, if the displayed pre-stored channel is the last channel of the pre-stored channel, the main power of the television is not on, the television is not off, and the on-time reservation mode is not on, It is determined whether the main power of the television is in the off state, and when the main power of the television is not in the off state, it is determined whether the television is in the off state and the operation is performed accordingly. Will be terminated.

According to the configuration and operation of the method for controlling the on-time reservation mode of the television according to the embodiment of the present invention described above, in the on-time reservation mode, the pre-stored channel after turning on the television to the initial channel of the channel previously stored in the reserved on-time By switching to the last channel of the channel by a predetermined time and displaying the pre-stored channel, it is possible to prevent the television from being turned on by a channel having no broadcast signal or a low volume in the on-time reservation mode.
