The present invention relates to a video cassette recorder capable of scheduled recording of a telephone (hereinafter referred to as V-seal), and more particularly, to a tape amount corresponding to the remaining amount of tape and a scheduled recording time input during telephone reservation recording. The present invention relates to a reservation recording method of V-Cal for performing scheduled recording by using the recorded recording part.

Home automation is rapidly progressing as the nuclear information family in the modern information society and the dualization of husband and wife are becoming more common. In addition, as a member of a society, long-distance travel and travel of individuals are increasing, so that information is frequently acquired far from home. One of the pieces of information thus obtained is information about a television broadcast program, and a user often feels the necessity of recording these programs with V-Cal.

However, in the conventional RT-reserved recording method, reservation recording is performed by inputting reservation recording input information using a panel key on the front panel or a remote controller made of V-SR key metrics.

Therefore, there is a problem that reservation recording using V-CAL cannot be performed at a distance away from V-C-AL.

In order to solve this problem, the applicant of the present invention has applied for a telephone reservation VLC system (Patent Application No. 93-4526) that can perform reservation recording of VSR using a telephone. In the reservation VRC system proposed by the applicant, it is possible to perform the reservation recording of the VRC from the outside by using a telephone connected to the VRC performing the reservation recording.

In the scheduled recording method, when a user makes a phone call, a predetermined ringing tone is output and a message for inputting reserved recording information is output when the recording tape is inserted in the VRT. If you hang up the phone after pressing the corresponding button, call schedule recording is performed.

However, since the remaining amount of the remaining tape is not known when performing the scheduled recording as described above, if the remaining amount of the remaining tape is less than the amount of the tape corresponding to the reserved recording time, the recording is not performed until the end. There was a problem in that it was impossible to record a program that must be recorded.

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 use a reserved recording portion recorded by comparing the remaining amount of tape with a tape amount corresponding to an input recording time of recording during telephone reservation recording. By performing the scheduled recording, the user provides a reservation recording method of V-SI for enabling the user to selectively perform the scheduled recording.

The remaining amount notification method of the recording tape according to the present invention for achieving the above object is characterized in that the remaining tape detection step of detecting the remaining amount of the tape inserted in the tape deck when the hooking switch is turned off and driving in the reserved recording mode; ; And performing reservation recording by using the reserved recording portion recorded by comparing the recording time of the detected tape remaining amount with the input reserved recording time.

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

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

1 is a configuration diagram of hardware to which the present invention is applied and includes a digital to analog converter (D / A) converter 10, a voice storage unit 11, a microcomputer 12, and a dual tone multi frequency (DTMF) signal detector. (13), the hooking switch 14, the tape remaining amount detection unit 15, the deck unit 16, and the audio signal processing unit 17.

At this time, the telephone ring detection unit (not shown) detects a predetermined number of telephone rings from the telephone 2 connected to the VAL and outputs the telephone ring signal to the microcomputer 12, and the microcomputer 12 applies the hooking signal to the hooking switch 14. The hooking switch 14 is configured to be hooked off according to the hooking signal applied from the microcomputer 12 to apply the DTMF signal applied from the telephone line to the DTMF detecting unit 13, and the DTMF detection is performed. The unit 13 decodes the DTMF signal to be applied to the microcomputer 12.

That is, the microcomputer 12 outputs a control signal corresponding to the DTMF signal decoded from the DTMF sensing unit 13, and the microcomputer 12 outputs, for example, a DTMF input from the DTMF signal sensing unit 13. If the signal is a DTMF signal for the reserved recording information, the deck unit 16 is controlled to be driven in the reserved recording mode, and the recording time and input for the remaining tape amount input from the tape remaining amount detection unit 15 are input. If the recording time for the remaining tape amount input from the tape remaining amount detection unit 15 is less than the reserved recording time by comparing the reserved recording time in the reserved recording information, check the result and the audio of the recorded contents recorded on the tape. The voice storage unit 11 is controlled to output a voice message for inputting a predetermined key for recording.

At this time, the remaining tape detection unit 15 detects the remaining amount of the recording tape inserted into the deck unit 16 and outputs the remaining tape amount to the microcomputer 12, as described above. The tape reel area is calculated and detected from the reel rotation speed output from the bar, and those skilled in the art can easily understand the detailed description thereof.

In addition, if the DTMF signal input from the DTMF signal detection unit 13 is a signal for confirming the audio of the recorded contents, the microcomputer 12 performs the rewind mode up to the beginning of the recorded contents, and records the recorded contents. The audio signal processor 17 controls the audio signal processor 17 to reproduce and output a voice of the audio signal. The audio signal processor 17 reproduces and processes the audio of the recorded contents according to the control signal output from the microcomputer 12. When the user is notified through the telephone line, the microcomputer 12 controls the voice storage unit 11 to output a voice message for inputting a predetermined key input for selecting a reserved recording mode for recording in the recorded recording part. .

At this time, the microcomputer 12 controls the voice storage unit 11 to output a reserved recording completion message if a predetermined key signal input, that is, a signal output from the DTMF signal detection unit 13 is a reserved recording selection signal. If the signal output from the DTMF signal detection unit 13 is not the reserved recording selection signal, the fast forward mode to the end of the recorded recording is performed and then converted to the stop mode, and the voice recording is performed to output the reserved recording completion message. By controlling the unit 11, the reservation recording can be selected.

At this time, the D / A converter 10 connected to the voice storage unit 10 is configured to convert the voice signal output from the voice storage unit 11 into a digital signal to notify the user remotely over the telephone line. .

4 is a flowchart for performing a reservation recording method of a VRC according to the present invention.

First, the microcomputer 12 applies the hooking signal to the hooking switch 14 to make the hooking off state (200). If the hooking off state is ready, the ready recording mode is completed. In operation 201, it is determined whether a reservation date, a reservation recording start time, a reservation recording end time, and input of a channel are completed.

As a result of determination, when the input of the reserved recording information is completed, the remaining amount of the recording tape inserted in the deck unit 16 is detected (202), and the time for the detected remaining tape amount is compared with the input reserved recording time ( 203) If the detected time remaining on the tape is less than the scheduled recording time, a voice message for confirming the data of the insufficient scheduled recording time and the recorded recording contents and inputting a predetermined key for performing the scheduled recording is provided. If the time for the detected tape remaining amount is greater than the reserved recording time, the reserved recording completion message is output (212).

At this time, when a predetermined key signal is input, the microcomputer 12 performs a rewind mode (REW: Rewind) to the front of the recorded recording content (205), reproduces and outputs the audio of the recorded recording content, and reserves it. A voice message for making a predetermined key input for catering to the recording is output (208, 209).

At this time, if a predetermined key signal is not input, the microcomputer 12 outputs a reserved recording completion message (212).

The microcomputer 12 outputs a reserved recording completion message when the key signal for the reservation recording selection is input, and fast-forwards to the end of the recorded recording mode when the key signal for the reservation recording selection is not input. After performing Fast Foward (210), the mode changes to the stop mode (211), and outputs a reserved recording completion message (212).

As described above, the V-DA reservation recording method according to the present invention compares the amount of the tape corresponding to the reserved recording time input with the remaining amount of the recording tape inserted in the deck when the telephone reservation recording is performed. If the remaining amount of recording tape inserted in the camera is less than the tape corresponding to the scheduled recording time, the user is informed that the remaining tape is insufficient and the voice of the last recorded tape is output. By outputting a message indicating whether to perform a scheduled recording using, i.e., a message to select the reservation recording catering, there is an effect that the user can selectively perform the reservation recording.

While the invention has been shown and described with respect to certain preferred embodiments, those skilled in the art will recognize that various modifications and changes can occur without departing from the spirit and scope of the invention as set forth in the claims below.
