Description

Multi-Time Scheduling Method on Television Receiver

The present invention relates to a time reservation function of a television receiver (hereinafter referred to as a TV), and more particularly, allows a user to set a plurality of reservation times for automatic on / off operation of a TV screen and automatically A method of causing an on / off operation to be performed several times in accordance with the scheduled time.

In general, a TV is for receiving and watching a broadcast signal transmitted from a broadcasting station, and a main component thereof is illustrated in FIG. 1.

Referring to FIG. 1, the microcomputer 200 generally controls the operation of the TV by the key input unit 220, and the memory unit 240 stores the data to be processed by the microcomputer 200. And a tuner 100 that receives and tunes a broadcast signal of a channel selected by the tuner voltage output from the microcomputer 200, and processes a video signal of the broadcast signal tuned by the tuner 100. There is an image processor 300 and an image amplifier 320 for amplifying the image signal output from the image processor 300.

In addition, the vertical / horizontally deflecting the vertical synchronizing signal and the horizontal synchronizing signal of the image signal displayed on the screen (ie, the screen of the TV) of the CRT 400 by the vertical / horizontal synchronizing signal processed by the image processor 300. There is a synchronization processor 340 and a CRT 400 for receiving an image signal output from the image amplifier 320 and displaying it on a screen.

A voice processor 500 for processing a voice signal of the broadcast signal received by the tuner 100, a voice amplifier 520 for amplifying the voice signal processed by the voice processor 500 to a predetermined level; The speaker 600 and 620 are configured to receive and output a voice signal amplified by the voice amplifier 520 to allow a viewer to listen to the voice.

Referring to the operation relationship of the general TV configured as described above, when the viewer operates the key input unit 220 to select the broadcast channel to be watched, the microcomputer 200 recognizes the tuner to generate a tuner voltage corresponding thereto. 100). Accordingly, the tuner 100 tunes the broadcast signal of the broadcast channel selected by the tuner voltage generated by the microcomputer 200 through the antenna ANT to tune the broadcast signal received from the free space to the image processor 300 and the audio processor 500. ) Inputs a broadcast signal.

Thus, the image processor 300 processes the image signal from the broadcast signal tuned by the tuner 100 and processes the image signal by the control signal of the microcomputer 200 and inputs the image signal to the image amplifier 320. That is, the image amplifier 320 amplifies the video signal to a level that can be displayed on the screen of the CRT 400, is supplied to the CRT 400, and eventually the video signal transmitted from the broadcasting station to the free space is displayed on the screen of the CRT 400. As it is displayed, the viewer watches the video.

Here, the vertical / horizontal synchronization processor 340 deflects the image displayed on the screen of the CRT 400 in the vertical direction and the horizontal direction based on the vertical synchronization signal and the horizontal synchronization signal processed by the image processor 300.

In addition, the voice processor 500 processes the voice signal from the broadcast signal tuned from the tuner 100 and inputs the processed voice signal into the voice amplifier 520. Accordingly, the voice amplifier 520 amplifies the voice signal processed by the voice processor 500 to a predetermined level and outputs the same to the speakers 600 and 620 so that the viewer can listen to the voice.

Even in a conventional TV having the above operation, there is a time reservation function for the automatic on / off operation of the screen of the CRT 400. The microcomputer 200 normally checks whether the current time has reached the reservation time using a built-in timer (not shown), and controls the screen to be turned on (if it is turned on if it is turned on) when the check time reaches the reservation time. .

If only the process of controlling the microcomputer 200 to turn off the screen CRT (400) is as follows. The vertical / horizontal synchronization processor 340 has a horizontal output circuit which serves to flow a suitable sawtooth current to the horizontal deflection coil. In addition, the high voltage circuit, which is not shown, increases the rectified voltage generated in the horizontal return period in the horizontal output circuit and rectifies the rectified voltage to supply the DC high voltage required by the anode of the CRT. Therefore, the microcomputer 200 controls the horizontal output circuit in the vertical / horizontal synchronization processor 340 not to generate a pulse voltage so that the high voltage circuit does not supply the DC high voltage to the CRT.

The conventional TV has a function of automatically turning on or off the screen when the reservation time is reached as described above. The time reservation for the operation may be made only one time. That is, for example, only the number of times when the off reservation is made at 1 am and the number of times when the off reservation is made at 6:30 am is possible. So, when one of the family sleeps, change the auto-on reservation time to 3:00 am to watch satellite broadcast at 3 am, watch the satellite broadcast at 3 am, When turned off, the time reservation of 6:30 is canceled and only the time of 3 am is reserved instead.

In the conventional TV time reservation function, the automatic power-on operation is not performed at 6:30 as expected in the family in the above case. That is, since the conventional TV time reservation function can set only one reservation time for the same operation, there is a remarkable drawback in that several people in the family use the time reservation function with one TV.

The present invention to solve the above-described drawbacks, the object of the present invention is to enable the user to set a plurality of reservation time for the automatic on / off operation of the TV screen, and automatically turn on / off operation of the TV screen It is to provide a function that can be performed several times according to the scheduled time.

A feature of the present invention for achieving the above object includes a predetermined key input means, storage means for storing time reservation data for an operation mode, a CRT for displaying an image signal, and control means for controlling various operation matters. In the time reservation method in a television receiver, when the user inputs a plurality of time reservation items for each operation mode for a predetermined number of operation modes through the key input means, the control means is displayed on the screen of the CRT. A first process of displaying reservation details and storing all of them in the storage means, a second process of accessing the reservation time data set in the first process from the storage means when the user turns on the time reservation function; And a third process of executing a reserved operation mode when the reserved time accessed in the second process is reached. It features.

An additional feature of the present invention for achieving the above object is that, in the first process, the reservation details data further includes data on the name of the user who makes the reservation. In another aspect of the present invention, the second process is to set the earliest time after the current time of access among the reserved time data to be accessed as the scheduled time for the scheduled operation mode to be performed.

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

First, since the apparatus configuration for the multi-time reservation method of the TV used in the present invention is not significantly different from that shown in FIG. 1, the configuration of FIG. 1 and the operation sequence shown in FIG. An embodiment is described.

2 is an operation flowchart for multiple time reservation of the automatic on / off operation of the TV screen according to an embodiment of the present invention.

If the initial state (S10) is a state that the screen of the TV receiver 400 is turned on, the microcomputer 200 determines whether the user turned on the multi-time reservation function key (S20), if the determination result is not turned on ( No) perform a basic (single) time scheduling function (S30). If the multi-time reservation function key is turned on (Yes), the microcomputer 200 accesses the reservation time data for the auto-off operation in the memory unit 240 (S21). The earliest reserved time after the current time of access among the plurality of accessed data is set as the reserved time for performing the auto-off operation.

For example, suppose the time reservation data is 06:40, 8:10, and 23 o'clock as the off reservation time, and 06:30, 08 and 19 o'clock as the on reservation time. When the time at which the auto off reservation time is accessed is 06:31, the reservation time for the auto off operation is set to 06:40. If the time of data access is, for example, 08:50, the scheduled time for the auto-off operation is 23:00. Automatic reservation time data may be compared including the date.

Subsequent to the setting process (S21), the microcomputer 200 determines whether the current time has reached the set reservation time (S22), and if so, turns off the reserved operation mode, that is, the water pipe 400 screen. . The method of turning off the screen is the same as that of the related art, which does not transfer the pulse voltage from the vertical / horizontal synchronization processor 340 to a high voltage circuit (not shown) that supplies a high voltage current to the water pipe 400. This is done by controlling.

Although the above description has been made only for the auto-off operation, the application can be easily applied to an operation mode in which the initial state is turned on according to the auto-on reservation time when the screen is turned off. As described above, the reservation operation mode is sequentially performed according to the plurality of reservation times, so that in the case of the above reservation time, the TV is automatically turned on at 6:30 am and automatically turned off at 6:40 am. Then, the TV turns on automatically at 8:00 am. Therefore, when there is a person who gets up and goes out at 6:30 in the family and a person who gets up and goes out at 8:00, the plurality of time reservation functions of the present invention are very effective.

If the reservation time has not been reached in the determination step S22 (No), after performing another programmed operation mode (S40), the process returns to step S22 to determine whether the reservation time has been reached. As described above, when the user wants to change the time schedule while another operation mode is executed in the loop.

That is, the microcomputer 200 determines whether there is a reservation time change signal (S50), and if there is a signal (Yes), existing reservation data is accessed from the memory unit 240 and is displayed on the screen of the water pipe 400. It is displayed (S51). The user changes the on / off reservation time and the name of the reservation through the key input unit 220 as desired (S52).

In the above-described reservation details change step (S52), the user may set a plurality of times for one operation mode as a reservation time for changing and setting. In addition, the user may input a user's name (or a symbol for a name) to be reserved in the reservation data, and the data is displayed on the screen of the receiving hall 400 (S51). You can check whether you have set.

After the reservation change step (S52), the microcomputer 200 returns to step (S20) to determine whether the multi-time reservation function key is on, so that the microcomputer 200 operates according to the reservation item just changed.

As described above, the present invention provides a function of allowing a viewer to make a plurality of time reservations for an automatic on / off operation of a TV screen through a key input unit and thereby automatically turn the screen on or off several times. It is effective to let multiple people receive information as the screen is turned on / off at a desired time.

In addition, in the above description, only the automatic on / off operation of the screen has been described. However, the present invention is not limited thereto, and for example, the automatic recording operation mode can be applied, so that the scheduled recording is automatically performed as many times as the recording capacity allows. Various applications are possible for those skilled in the art.
