Description

Multi-channel schedule recording method of video cassette recorder

The present invention relates to a scheduled recording method of a video cassette recorder, and more particularly, to a multi-channel scheduled recording method of a video cassette recorder for recording programs having different broadcasting time zones and broadcasting channels on the same tape.

In general, a video cassette recorder has a recording function for recording a composite video signal applied from a tuner tuned into a desired channel to a broadcast signal received through an antenna, and a composite video signal recorded on the magnetic tape to reproduce a television. It has a playback function to display on the monitor.

In addition, the video cassette recorder has a reserved recording function, which is a very advantageous function of automatically recording a broadcast program desired by the user in the absence of the user, so that the user can play and watch it at a desired time. These types of scheduled recording include scheduled recording once to perform scheduled recording at a specific time desired, daily scheduled recording to perform daily recording if you set a schedule for a program that is broadcasted at the same time every day. There are weekly scheduled recordings that perform scheduled recording on the day of the week.

The scheduled recording function records the broadcast program in advance by recording the reservation information input by the user (for example, the broadcast date, start time, end time, broadcast channel of the desired program, recording speed, etc.) of the desired program. As a function that can be performed, a normal scheduled recording procedure is to first press the function selection button, the scheduled recording button in sequence, enter the number of channels to be recorded, and then set the recording date and recording start time and recording end time, After setting the recording speed, a tape to be recorded was inserted into the deck, and then scheduled recording was performed by turning off the power.

At this time, the recording speed is classified into SP (Standard Play) mode, LP (Long Play) mode, and EP (Extended Play) mode. The SP mode is a standard mode, the LP mode is a double mode, and the EP mode is a triple mode. As an example, when the same amount of tape is used, the EP mode can record three times more information than the SP mode, and the LP mode can record two times more information than the SP mode.

In the reservation recording method performed by such a process, it has conventionally been impossible to simultaneously record programs that are broadcast on different channels in the same time zone.

That is, for example, there is a program that is broadcast from 9 pm to 11 pm on the first channel, and a program that is broadcast from 10 pm to 10:30 pm on the second channel can be recorded simultaneously with the conventional reservation recording method. Could not.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to perform scheduled recording by switching to a channel where a corresponding program is aired according to the airing time of each program in each of the multi-channel programs that are aired at the same time. Therefore, the present invention provides a multi-channel reservation recording method of a video cassette recorder for recording a multi-channel program that is broadcast at the same time zone on the same tape.

In order to achieve the above object, the present invention provides a video cassette recorder which reserves and records a program of a first channel and a program of a second channel that is broadcasted later than a program of the first channel and belongs to a broadcast time zone of the program of the first channel. A multi-channel reservation recording method comprising: a first process of storing reservation recording information about a program to be recorded in the first channel and the second channel when the recording is performed; A second process of recording a program of the first channel if a scheduled recording start time for recording the program of the first channel is performed from the reserved recording information of the first process; A third step of pausing recording if the current time during recording of the program of the first channel is a scheduled recording start time for recording the program of the second channel; A fourth process of pausing program recording of the first channel and switching to the second channel to record the second channel program until a reserved recording end time of the reserved recording information; A fifth step of determining whether the time when the recording of the program of the second channel has ended has passed the total recording time of the program of the first channel and the second channel; A sixth step of stopping the recording and switching to the stop mode when the time when the recording of the program of the second channel has ended has elapsed the total recording time; A seventh process of pausing the recording and switching to the first channel if the recording time of the program of the second channel does not pass the total recording time; And an eighth process of recording a program of the first channel until the total recording time after switching to the first channel.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

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

1 is a block diagram showing the configuration of a reservation recording apparatus of a video cassette recorder according to the present invention.

The key input unit 10 is configured by a key matrix and provides a predetermined key signal pressed by a user to the control unit 20, and has a plurality of keys for controlling the operation of the video cassette recorder.

That is, the signal according to the multi-channel reserved recording key for performing the present invention from the key input unit 10 and the key signal according to the reserved recording information setting for the reserved recording of the multi-channel program, that is, each channel data to be recorded, each When a key signal for reserved recording information such as a reserved recording start time, a reserved recording end time, a recording speed, and the like of a program of a channel is provided, the control unit 20 stores it in an internal memory (not shown).

The controller 20 counts the current time, and if the current time is the scheduled recording start time of the program of the corresponding channel among the multi-channel programs provided by the key input unit 10, the tuner performs a channel tuning control signal for recording the corresponding channel. 30).

Accordingly, the tuner 30 tunes a channel corresponding to the channel tuning control signal provided by the controller 20 to receive a broadcast signal of the tuned channel and provides it to the integral frequency (IF) signal processor 40. In addition, the IF signal processor 40 demodulates the broadcast signal provided by the tuner 30 to provide an audio signal to the audio signal processor 50 and a video signal to the video signal processor 60.

At this time, the audio signal processor 50 processes the audio signal provided from the IF signal processor 40 to the head amplifier 70 under the control of the controller 20, and the video signal processor 60 supplies the IF signal. The video signal provided from the processor 40 is processed under the control of the controller 20 and provided to the head amplifier 70.

The head amplifier 70 amplifies the audio signal provided from the audio signal processor 50 and the video signal provided from the video signal processor 60 to the deck unit 80 under the control of the controller 20. The deck unit 80 records the audio signal and the video signal provided from the head amplifier 70 on the magnetic tape.

At this time, the control unit 20 switches the channel when the start time for recording the program of another channel is reached from the reserved recording information stored in the internal memory while recording the program of one channel among the multiple channels as described above. The tuner 30 is controlled, and accordingly, the tuner 30 switches channels and receives a broadcast signal of a corresponding program and provides the IF signal to the IF signal processor 40 to repeat the above-described recording process.

Meanwhile, the controller 20 controls the deck unit 80 to switch to the stop mode when the recording execution time is the total recording time, that is, the total recording time of each program of the multi-channel set by the reserved recording information has elapsed. Turn off the power supply to the recorder.

FIG. 2 is a flowchart illustrating a process of storing reserved recording information for a program to be recorded in each channel during multi-channel reserved recording of a video cassette recorder according to the present invention, and FIG. 3 is reserved recording information set by FIG. FIG. 1 is a flowchart illustrating a process of performing reservation recording of multiple channels by using the block diagram shown in FIG. 1.

Here, in the reserved recording of programs of multiple channels, that is, the first channel and the second channel, the program airing time of the first channel is longer than the program airing time of the second channel, and the program of the first channel is higher than the program of the second channel. It airs quickly.

First, as can be seen in the flowchart shown in FIG. 2, a process for reserved recording of programs of multiple channels, that is, a first channel and a second channel, is as follows.

That is, the controller 20 determines whether a key signal for reserved recording of a multi-channel program is provided from the key input unit 10 in step 200. The process proceeds to the step of displaying a menu screen for inputting reservation recording information according to multi-channel recording.

That is, a menu screen is displayed so that reserved recording information such as recording start time and recording end time, recording channel, and the like of the first channel data and the second channel data, and the program to be scheduled recording among programs of each channel can be input.

At this time, if the reserved recording information displayed on the menu screen is input by the user through the key input unit 10, the control unit 20 stores in the internal memory (not shown) (step 220).

When the reserved recording information for each channel is input as described above, the controller 20 performs reserved recording for each of the programs of the multi-channel as described below.

First, the controller 20 detects the reserved recording start time stored in the internal memory in step 300 and proceeds to step 301 when the reserved recording start time is stored.

That is, if the current time is the time for starting the scheduled recording of the program of the first channel (as can be seen above, the program of the first channel has a faster airing time than the program of the second channel). In operation 301, the deck unit 80 is controlled to record the program of the first channel according to the recording speed of the preset reservation recording information.

Therefore, the deck unit 80 records the audio signal and the video signal provided from the head amplifier 70 on the magnetic tape.

At this time, the control unit 20 detects the current time (step 302), and determines whether the current time is the start time zone for recording the program of the second channel (step 303). As a result of the determination, if the current time is the start time for recording the program of the second channel, the process proceeds to step 304 to control the deck unit 80 to pause recording and proceeds to step 305 to perform the first channel. Switch the channel to the second channel.

Accordingly, the tuner 30 tunes the second channel under the control of the control unit 20 and tunes the broadcast signal to the IF signal processor 40, the audio signal processor 50, the video signal processor 60, and the head amplifier. 70 is provided to the deck unit 80 to be recorded (step 306).

As described above, while recording the program of the second channel, the control unit 20 continuously detects the current time (step 307) so that the current time is the recording time of the reserved recording information stored in the internal memory, that is, the program of the second channel. If the recording time (recording end time-recording start time) has elapsed (step 308), the flow proceeds to step 309.

The controller 20 proceeds to step 309. If the time after the recording of the program of the second channel ends, the total recording time elapses, that is, the sum of the recording times of the programs of the first channel and the second channel, elapses. If the total recording time has not elapsed, the process proceeds to step 310.

That is, the control unit 20 converts the deck unit 80 to the stop mode in step 314, and proceeds to step 310, converts the deck unit 80 to the pause mode, and then proceeds to step 311. The tuner 30 is controlled to switch, that is, switch from the second channel to the first channel.

Accordingly, the tuner 30 is switched to the first channel to tune the corresponding program and tune the broadcast signal to the IF signal processor 40, the audio signal processor 50, the video signal processor 60, and the head amplifier 70. It is provided to the deck unit 80 to be recorded (step 312).

At this time, the controller 20 proceeds to step 313 and if the program recording time of the first channel has passed the total recording time, proceeds to step 314 and the program recording time of the first channel has not passed the total recording time. If so, the process returns to step 312 to continue recording until the total recording time is reached.

As described above, the multi-channel scheduled recording method of the video cassette recorder according to the present invention includes a program of the second channel which is broadcasted later than the program of the first channel and the first channel and belongs to the broadcast time zone of the program of the first channel. After recording and recording the reserved recording information for the programs of the first channel and the second channel for reserved recording on the same tape, if the time for recording the program of the second channel is being recorded while recording the program of the first channel, the first After the program recording of the channel is paused, if the recording time is switched to the second channel and the recording end time has passed the total recording time of the program of the first channel and the second channel, the recording mode is changed to the stop mode. If the end time of recording a program has not passed the total recording time, switch to the first channel until the total recording time is reached. By so as to perform the recording, there is an effect that it is possible to record a program of a multi-channel are shown on the same time zone on the same tape.

While the invention has been shown and described with respect to certain preferred embodiments, it will be apparent to those skilled in the art that various modifications, changes and omissions can be made without departing from the spirit and scope of the invention.
