Description

VRT with reservation telephone function and its control method

The present invention relates to a VRL equipped with a reservation telephone function and a control method thereof. In particular, the time and number to call the VRL system are inputted, and when the set time of the scheduled telephone reservation is elapsed while the VRL is being viewed, By temporarily suspending and making a call through an external telephone, there is no need to completely stop the VRC viewing function due to a telephone call. It's about.

In general, a VRC system is a device that records video and audio signals (black and white and color) on a magnetic tape, and reproduces them by reproducing the video.

In addition, such a VR system is in principle the same as a tape recorder, but since the frequency band of the video signal is wider than that of the audio signal, the relative speed of the tape head needs to be high.

For this reason, a video signal is recorded by rotating a head drum having four or two heads at a speed of several hundred times per second perpendicular to the tape travel direction. Then, referring to FIG. 1, an example of such a V-AL system will be described. A head drum 72 provided with a plurality of heads 71 for reproducing or recording an information signal recorded in the video tape 70 and the video tape A capstan motor 75 for driving the supply reel 73 and the winding reel 74 to rotate the tape 70 according to a set mode signal when the 70 is loaded, and driving of the capstan motor 75. A microcomputer 76 for controlling the overall function of the system, a loading motor driver 78 for rotating the loading motor 77 according to the setting mode control signal of the microcomputer 76, and the loading motor 77 A mode switch 79 for switching the mode signal set by the rotational driving of the display device, and a predetermined signal processing of the video and audio signals input from the head 71 according to the operation control signal of the microcomputer 76; And the image output to the speaker 81 and It consists of a voice signal processor 82.

In addition, a key input unit 83 for inputting a function setting signal of a user is connected to one end of the microcomputer 76.

On the other hand, referring to the operation of the conventional V-Cal system configured as described above, if the user wants to play the video tape 70, the video tape 70 is inserted into the deck by the front door and the key input unit 83 When the regeneration function is set through the microcomputer 76, the microcomputer 76 recognizes this and applies a driving voltage through the loading motor driver 78 to drive the loading motor 77. Then, the mode switch 79 is set to the mode in which the loading motor 77 is driven, for example, the regeneration mode is performed. Accordingly, as the mode switch 79 is switched to the regeneration mode position, the pole base 84 quickly guides the video tape 70 to contact the head drum 72.

At the same time as the above operation, the microcomputer 76 drives the capstan motor 75 and the drum motor 85 according to the set playback mode, wherein the video tape 70 is connected to the head drum 72 from the supply reel 73. ) Will move around the winding reel (74).

At this time, the head 71 provided on the head drum 72 detects the information contained in the video tape 70 and inputs it to the video and audio signal processor 82. Therefore, the video and audio signal processor 82 processes the video and audio signals of the input video tape 70 by a predetermined signal and displays them on the display 80 and the speaker 81.

However, the conventional VRC system as described above is versatile to meet the needs of the user. For example, since the telephone reservation time message function is not provided, the user often forgets to make a call due to the VRL viewing. As a result, the functionality of the VRT system is considerably deteriorated. In addition, if the user needs to make a phone call while watching the videotape 70, the function of the VRT is completely stopped or the videotape 70 after the telephone call is completed. ) To rewind back to the position they were watching, so there was a disadvantage in that it was quite inconvenient to use.

Accordingly, the present invention has been invented to solve the above-mentioned shortcomings, by entering the time and number to call the V-CAL system, and suspends the function mode of the V-CAL when the set call reservation time elapses while watching the V-Cal. By making a call through an external telephone, it is not necessary to completely stop the viewing function of V-Cal due to a telephone call, thereby providing V-Cal equipped with a reservation telephone function and its control method which improves the convenience of use. The purpose is.

Another object of the present invention is to display the reservation time of the telephone during the viewing of the V-Cal through the display so that the user does not forget the urgent telephone call time, according to which the functionality of the system is also significantly improved It is to provide VRC and its control method.

The present invention for achieving the above object is a capstan motor for rotating the tape according to the set mode signal by driving the supply reel and winding reel when loading the video tape, and controlling the reservation telephone function including the drive of the capstan motor A phone number code signal reserved by a microcomputer, a memory unit connected to one end of the microcomputer to store a user's reserved telephone time and telephone number, and a microcomputer of a telephone connected to an external line according to the telephone number code transmission control signal of the microcomputer; Characterized in that consisting of a telephone signal processing unit for inputting.

The VR of the present invention includes a head drum 3 provided with a plurality of heads 2 for reproducing or recording an information signal recorded in the video tape 1, and the video tape 1 being loaded as shown in FIG. The capstan motor 6 for driving the supply reel 4 and the take-up reel 5 to rotate the tape 1 according to the set mode signal, and the function of the system including the driving of the capstan motor 6. A microcomputer 7 for controlling overall reserved phone functions, a memory unit 8 connected to one end of the microcomputer 7, and storing a user's reserved phone time and phone number; The telephone signal processing unit 11 inputs a telephone number code signal reserved to the microcomputer 10 of the telephone 9 connected to the external line according to the telephone number code transmission control signal.

Then, one end of the microcomputer 7 is connected with a timer 12 for checking a set telephone reservation time, and another end of the microcomputer 7 is a loading motor driver 14 for rotationally driving the loading motor 13. ) Is connected, and a mode switch 15 for switching the set mode signal on the power transmission path of the loading motor 13 is installed.

In addition, at one end of the microcomputer 7, a video signal processor 16 for processing video signals to be reproduced or recorded by the head 2 and audio signals reproduced or recorded from the head 2 are voiced. The audio signal processor 17 for signal processing is connected, and the other end of the microcomputer 7 is connected with a key input unit 18 for inputting a function setting signal of the user, and the other end of the microcomputer 7 has a character. An OS 19 that generates a signal is connected.

A display 20 is connected to the video signal processor 16, and a speaker 21 is connected to the audio signal processor 17.

Here, the telephone 9 is generally provided with a telephone circuit 22 for transmitting and receiving a call signal through a telephone line and a dial 23 for transmitting a telephone number.

Next will be described the method of the present invention applied to the VRC system having the above configuration.

In the method of the present invention, as shown in FIG. 3, the microcomputer proceeds from the initial step (S1) to the telephone reservation function setting determination step (S2) to determine whether the telephone reservation function is currently set in the VRC system. When the telephone reservation function is not set, as a result of the determination in the telephone reservation function setting determination step (S2), the method proceeds to the mode setting determination step (S3) to determine whether a setting signal for setting the function mode is input from the current user. .

As a result of the determination during the mode setting determination step (S3), if the setting signal for setting the function mode is not set by the current user, the process proceeds to the end step. However, if the function mode is set by the user as a result of the determination during the mode setting determination step (S3), the process proceeds to the setting function mode execution step (S4) to execute the set mode function, for example, the play function (PLAY).

That is, when the user wants to execute the setting mode, for example, the playback mode function, the video tape 1 is inserted into the front door and the playback mode function is set through the key input unit 18. Then, the microcomputer 7 recognizes this. By driving a driving voltage through the loading motor driver 14 to drive the loading motor (13).

Then, the mode switch 15 is switched to the mode in which the mode switch 15 is set by the driving of the loading motor 13, for example, switching to the regeneration mode. Accordingly, as the mode switch 15 switches to the reproduction mode, the pole base 24 quickly guides the video tape 1 to come into contact with the head drum 3.

At the same time as the above operation, the microcomputer 7 drives the capstan motor 6 and the drum motor 25 according to the set mode, wherein the video tape 1 is supplied from the supply reel 4 to the head drum 3. It will move around the winding reel (5). Therefore, the head 2 provided on the head drum 3 detects the information contained in the video tape 1 and inputs it to the video signal processor 16 and the audio signal processor 17, respectively. Then, the video signal processor 16 and the audio signal processor 17 process video and audio signals of the input video tape 1 through the display 20 and the speaker 21, respectively. Done. Therefore, the user can watch the information content of the video tape 1 output through the display 20 and the speaker 21.

On the other hand, when the telephone reservation function is set during the telephone reservation function setting determination step (S2), if the telephone reservation is set, the procedure proceeds to the telephone reservation data input display step (S5) to input the telephone reservation time and the telephone number by a text signal on the display. It is displayed. After the telephone reservation data input display step (S5), it proceeds to the reservation data input completion determination step (S6) to determine whether the telephone reservation time and telephone number data is set from the current user. Further, when the reservation data input completion determination step (S6) is determined as a result, if the telephone reservation time and telephone number data is not set, the process returns to the previous step (S5) and repeats the loop. However, as a result of the determination during the reservation data input completion determination step (S6), if the telephone reservation time and the telephone number data are input from the user, the procedure proceeds to the reservation telephone checking execution step (S7) to check the set telephone reservation time.

After the reservation telephone checking execution step (S7), the process proceeds to the setting function mode execution step (S4) to execute the set mode function. In addition, after the setting function mode execution step (S4), the process proceeds to the telephone reservation time period determination step (S8) to determine whether the current time has reached the set telephone reservation time. If the current time does not reach the preset telephone reservation time as a result of the determination in the telephone reservation time lapse determination step (S8), the process returns to the previous step (S4) and continues to execute the function mode of the VRC.

However, as a result of the determination during the telephone reservation time elapse determination step (S8), if the current time reaches the preset telephone reservation time, the procedure is performed to execute the VRC telephone call function execution step (S9) to temporarily stop the function of the VRL currently being executed. It stops and displays text signal on the display that the current time is the reservation time set by the user. At the same time, the set telephone number code signal is inputted to an external telephone connected to V-Cal to execute a telephone call.

Then, after the VRC telephone call function execution step (S9) to proceed to the telephone call end determination step (S10) to determine whether the telephone call is terminated. If the telephone call is not terminated as a result of the determination during this telephone call end determination step (S10), the process returns to the previous step (S9) and repeats the loop. However, as a result of the determination during the telephone call termination determination step (S10), if the telephone call is terminated, the procedure proceeds to the execution of the V-CAL function again (S11) to execute the function mode that was paused due to the telephone call.

In other words, when the telephone reservation function is set in the VRC system, the microcomputer 7 displays a menu screen for inputting the telephone reservation time and the telephone number signal on the display 20 through the OS. Then, when the user inputs the time to call and the telephone number signal using the key input unit 18, the microcomputer 7 inputs it to the memory unit 8 and drives the timer 12 to check the reserved telephone time. do. Then, the microcomputer 7 executes this playback mode if the function mode is set at the same time as the telephone reservation time checking operation.

Then, if the current time reaches the telephone reservation time while executing the V-CAL function, the microcomputer 7 displays a text signal indicating that the current time is the telephone reservation time on the display 20 through the OS part 19 and is currently executing. Pauses V-AL's function. At the same time, the microcomputer 7 inputs the reserved telephone number signal stored in the memory unit 8 to the telephone signal processing unit 11, whereby the telephone signal processing unit 11 constantly inputs the input telephone number signal. Signal processing, that is, converted into a telephone number code signal and then transmitted to the microcomputer 10 of the external telephone 9. Then, the microcomputer 10 of the external telephone 9 operates the dial 23 in accordance with the input telephone number code signal to transmit the telephone number signal to the telephone line. When the call partner and the telephone line are connected, the telephone call is made through the call circuit unit 22 of the external telephone 9. At this time, when the telephone call is terminated, the microcomputer 10 of the telephone 9 inputs a call end signal to the microcomputer 7 of the VRC. Accordingly, the VRC microcomputer 7 functions as a function of the VRC currently suspended. Run it again. Therefore, the user can continue to watch the information contents of the video tape 1 which he was watching before the telephone call without any key operation.

As described above, the present invention inputs a time and a number to call the BC-AL system and pauses the function mode of the BC-AL when the set time of the scheduled telephone call elapses while watching the VR, thereby making a call through the external telephone. In addition, it is not necessary to completely stop the VRC viewing function due to the phone call, thereby improving the convenience of use, and also displaying the reservation time of the phone through the display while watching the VLC. Therefore, the function of the system is also improved accordingly.
