Abstract

PURPOSE: To provide a magnetic recording/reproducing device which is capable of setting the reservation of timer recording indirectly from a remote place by using a telephone line and radio waves. CONSTITUTION: When a transmitting station 12 is called from a remote place and the telephone line becomes online, the code number of a magnetic recording/ reproducing device from which timer recording is demanded and the G-code of the program of which the timer recording is wanted are inputted through the phone 11. When the code number and the G-code sent through the telephone line are received at the receiver circuit 14, a transmitting circuit 15 transmits the radio waves superposed with the codes which waves the magnetic recording and receiving device usually receives for certain period of time. At the time when a receiver circuit 17 receives the radio waves on which the signal is superposed, a decoder circuit 18 decodes the signal. The signal decoded by the decoder 18 is inputted into a controller 19 to make the reservation setting of timer recording based on the above G-code. When the recording start time comes, a recording start command is issued to a recording section 30.

[0002]

2. Description of the Related Art In recent years, the number of newspapers and magazines with a TV program section in which a G code is posted has increased, and in response to this, G
A magnetic recording / reproducing device capable of setting a timer recording reservation by a code is becoming popular. The structure of the conventional magnetic recording / reproducing apparatus will be described below.

FIG. 2 is a block diagram of a conventional magnetic recording / reproducing apparatus having a G code reservation function. In FIG. 2, reference numeral 20 is a remote controller, 21 is an input section for inputting a G code, 22 is a transmission section for transmitting the G code input by the input section 21 to a video tape recorder (hereinafter referred to as VTR) 24, and 25 is a transmission section. The receiving unit for receiving the G code signal transmitted from the unit 22, 26 is a decoding unit for decoding the G code signal received by the receiving unit 26 into the reserved recording information, and 27 is the reserved recording information decoded by the decoding unit 26. The control unit controls the recording unit 28 based on the above.

The operation of the magnetic recording / reproducing apparatus configured as described above will be described. First, the G code of the program to be recorded is input using the input unit 21 of the remote controller 20. The input G code is VT from the transmission unit 22.
It is transmitted to R24 and received by the receiving unit 25 of VTR24. The received G code is decoded by the decoding unit 26 into recording reservation information and input to the control unit 27. The control unit 27 stores the recording unit 28 at the recording start time based on the recording reservation information.
To the recording start command.

[0005]

However, in the above-mentioned conventional configuration, the setting of the recording reservation by the G code input must be made directly to the magnetic recording / reproducing apparatus by using the remote controller, and the user can record the recording. If you forget to make a reservation and go out, there is a problem that you cannot record. The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a magnetic recording / reproducing apparatus capable of indirectly setting a timer recording reservation from a remote location by using a telephone line and radio waves. And

[0006]

In order to solve the above-mentioned problems, a magnetic recording / reproducing apparatus of the present invention is a magnetic recording / reproducing apparatus capable of recording reservation by inputting a code signal relating to recording reservation from a telephone and receiving it via transmitting means. Which receives the code signal transmitted from the telephone through the telephone line
Receiving circuit, a transmitting circuit that superimposes a code signal received by the first receiving circuit on a radio wave of a constant frequency that is being received by the present device, and transmits, and a transmitting means that includes the receiving circuit and the transmitting circuit. , A second receiving circuit for receiving a code signal superimposed on a radio wave of a certain frequency, a decoding section for decoding the code signal received by the second receiving circuit into recording reservation information, and a recording reservation decoded by the decoding section The control unit controls the recording operation based on the information, and the recording unit controls the recording operation of the control unit to perform the recording operation.

[0007]

With this configuration, the code No. of the magnetic recording / reproducing apparatus is connected to the transmitting apparatus via the telephone line. You can set the timer recording reservation for the program you want to record from a remote location simply by sending the G code and.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the magnetic recording / reproducing apparatus of this embodiment. 11 is a telephone, 12
Is a transmitting unit, 13 is a receiving circuit provided in the transmitting unit 12 for receiving information transmitted from the telephone 11 via a telephone line, and 14 is a signal received by the receiving circuit 13 and converted into radio waves which the VTR is constantly receiving. A transmitting circuit that superimposes and transmits for a certain time, 15 is a VTR main body, 17 is a receiving circuit that always receives a radio wave sent from the transmitting unit 12, and 18 is a receiving circuit 17
A decoding unit that decodes the signal superimposed on the radio wave received by the device, 19 is a control unit that sets timer recording reservation based on the decoded signal, and 30 is a recording operation under the control of the control unit 19. It is a recording unit.

The operation of the magnetic recording / reproducing apparatus of this embodiment having the above-described structure will be described below.
First, the transmitter 12 is called from a remote place. When the telephone line is online, the code No. of the magnetic recording and reproducing device you want to make timer recording. Then, the G code of the program to be recorded is input from the telephone 11. Code No. sent through the telephone line When the reception circuit 14 receives the G code and the G code, the transmission circuit 15 superimposes the code on the radio wave that the magnetic recording / reproducing apparatus always receives
Send for a certain period of time. When the receiving circuit 17 receives a signal that is always superimposed on the received radio wave, the decoding unit 18 decodes the signal. The signal decoded by the decoding unit 18 is input to the control unit 19, and the code N corresponding to the VTR 15 is input.
o. And the G code. The decoded signal is
Code No. corresponding to VTR15. And G code, the control unit 19 sets timer recording reservation based on the G code, and when the recording start time comes, the recording unit 30
To the recording start command.

As described above, according to the present embodiment, the timer recording reservation can be indirectly set even from a remote place where the timer recording reservation cannot be directly set in the magnetic recording / reproducing apparatus. Can be done
