The present invention relates to a channel reservation tuning method according to time slots in which a TV and a VCR capable of reserved reception of a TV broadcast can reserve a broadcast channel for each time zone of a broadcast program to watch a predetermined channel for a predetermined time at a predetermined time.

Since the TV broadcast is performed by a broadcast program prepared in advance on a daily or weekly basis for each broadcasting station, the user has to remember the channel and time to watch or watch the program guide and switch channels each time.

In other words, since the channel to be watched is different according to the broadcast time zone, the channel is changed according to time.

In the case of forcibly receiving a certain channel for a certain time and watching it to a specific target, that is, in order to watch an educational broadcast to a student, in the past, the channel and time had to be memorized and tuned in. In view of the above, the present invention reserves channel selection for each time zone of a broadcast program so as to watch a broadcast of a predetermined channel at a predetermined time for a predetermined time.

As described above, the present invention will be described in detail with reference to the accompanying drawings for the purpose of automatically tuning a predetermined channel to watch a program of a broadcast determined by a time zone among various programs by broadcasting stations without error or forced.

1 is a block diagram of the present invention, a key input unit 1 for applying a function key or a key input of a remote controller to the microcomputer 2, and a microcomputer performing a function of the present invention according to the key input of the key input unit 1 ( 2) and the OSD block 7 for recognizing the OSD signal data of the microcomputer 2 and displaying them as OSD characters on the monitor 8 and the channel tuning data of the microcomputer 2 to tune the channel. A tuner 3 for outputting a signal and a demodulator 4 for demodulating the IF signal and supplying video and audio signals to a video board 5 and an audio board 6 are provided. It is a general channel tuning configuration of the used TV and VCR.

The present invention aims to provide a method for enabling reserved viewing of a broadcast program at predetermined time intervals using such a known system block diagram.

Initially, the set time is set to the current time by inputting a key to the timer of the microcomputer 2 in the key input unit 1 by using a function key external to the set or a key of the remote controller.

At this time, the current time setting method of the set is to view the OSD characters of the OSD block 7 displayed by the monitor 8 and set the current time in the order of hour, minute, month, and day by using the numeric keys for channel selection. This time setting method is generally known publicly known technology.

After the current time setting of the set is completed, the reserved channel sequence (PROGRAM SEQUENCE NO) is set for each time zone.

The reserved channel sequence setting can be set by selecting the number indicating the channel (Timer Channel) for the reservation by calling the menu screen of the OSD block (7) from the microcomputer (2). ) Can be varied according to the memory capacity, but when the weekly time of watching TV during the day is about 10 hours, it is suitable for about 10 times.

In addition, the start time and end time and the time zone range and channel setting for each reserved channel sequence by time zone are set while viewing the OSD screen using the function keys and the numeric keys of the remote controller. When the desired time zone and the desired channel are all determined, the user calls up the menu screen and checks whether there is an incorrect setting of the reserved channel.

After accurately setting the desired time zone and channel as described above, the first tuned channel is watched and it is checked whether the current time matches the start time of the reserved channel.

That is, if the current time coincides with the start time of the reserved channel for each time zone while receiving the first tuned channel, the microcomputer 2 detects this and changes the data to enable tuning of the channel predetermined by the tuner 3. The tuner 3 converts the RF signal into the IF signal of the determined channel according to the data change, and applies the demodulator 4 to the demodulator 4. The demodulator 4 demodulates the video signal and the audio signal to the video board. ) And the audio board 6, the monitor 8 displays the changed channel.

If the current time coincides with the off time while automatically watching and broadcasting the set channel from the set start time as described above, the microcomputer 2 detects this and enables the first channel tuning before the channel set to the tuner 3 again. By sending the data, the toner 3 selects the first channel again.

At this time, when the end time of the set channel coincides with the start time of the next channel of the reserved channel sequence for each time zone, the channel is changed by the same method as described above in which the microcomputer 2 sends data to the tuner 3.

In this way, after all the reserved channels are performed according to the reserved channel order according to the time slots, the normal mode is returned. The flowchart of Micom which performs all such operations is as shown in FIG. 2 and the flowchart is as follows.

First, check whether the current time is set. If the current time is not set, use the function keys or the remote control keys to set the OSD screen.

After the current time is set, check if the program reserve channel order is set for the first time. If the program reserve channel order is not set for the first time, use the function keys or remote control keys to view the OSD screen.

When the program reservation channel sequence is set for the first time, check whether the start time, end time, and channel are set for each program reservation.If it is not set, the external function key or the remote control key can be used to view the menu screen of the OSD screen. Will let you.

In this way, after the start time, the end time according to the current time and the program reserved channel sequence, and the channel are set, it is checked whether the start time and the current time of the reserved channel coincide with each other. If the current time does not match the start time of the scheduled time, increase the time and compare whether the start time matches the current time + 1 second.

In other words, if the current time coincides with the start time of the reserved channel, broadcasting of the reserved channel can transmit the data to the tuner 3 so that the broadcast set at the set time can be viewed. In this way, while watching the broadcasting of the set channel, the current time and the end time are compared and the data is sent to the tuner 3 to return to the reception of the initial channel when the current time matches the end time of the reserved time. If the current time does not match the end time of the scheduled time, the end time is compared with the increasing time to see if the end time matches the current time + 1 second.

That is, when the current time matches the end time of the reserved time, the data is sent to the tuner 3 again so that the initial channel can be received. If the reservation program viewing order remains, compare the program with increasing time to see if the start time of the program matches the current time.

Therefore, the above process can be repeated until the reserved program viewing order remains, and the channel can be automatically watched in the set time zone up to the maximum program order. When the channel of the set program is tuned.

As described above, the present invention allows users to watch various broadcast programs on a desired time zone at a desired time period, so that the user can automatically watch a desired channel at a desired time for a desired time, so that they can watch more conveniently and freely.
