2. Description of the Related Art Conventionally, control information is written in a recording medium such as a magnetic tape (for example, a video tape or an audio tape) or an optical disk (for example, a video CD) by using a signal in an audible frequency band, and a voice or It has been considered to control the controlled device by reading the control information at the same time when the video is reproduced (Japanese Patent Laid-Open No. 6-231573).
issue). For example, the massage device is controlled by using the control information written in the audio recording area of the video tape, and at the same time, the video information written in the video recording area of the video tape is reproduced and displayed on the display device, and the audio recording area is displayed. It is considered that the effect of relaxation (transition from tension to relaxation) or refresh (transition from relaxation to tension) is enhanced by reproducing the written audio information and outputting it from the audio device. As the video information displayed on the display device and the sound output from the audio device, a video suitable for the purpose of relaxing or refreshing is selected.

As described above, when recording control information using a signal in the audio frequency band, a DTMF (dual tone multi-
The current situation is to use frequency) signals (hereinafter referred to as tone signals).

[0004]

By the way, since the tone signal is usually a signal of one unit by combining two kinds of frequencies, both frequencies are detected in order to extract the control information by the tone signal. , It is necessary to detect the combination of frequencies. Therefore, in order to detect a signal of one unit, at least one cycle of each frequency is required. On the other hand, since the minimum frequency of the tone signal is regulated to 697 Hz, the amount of data that can be transmitted in one second is regulated by this frequency. That is, the amount of data that can be transmitted per second is relatively small.

Since the transmission rate (that is, the recording density) of the control information is low as described above, there is a problem that the ratio of the control information in the audio area of the recording medium is large and the area for storing the audio information is small. Occurs. That is, when the necessary control information is recorded in the audio area of the recording medium,
There arises a problem that the audio information cannot be converted into stereo, or a sufficient amount of audio information cannot be recorded.

The present invention has been made in view of the above circumstances, and an object thereof is to increase the recording density of control information while writing the control information in a recording medium using a signal in an audible frequency band. Accordingly, it is an object of the present invention to provide a device control device in which the storage area for voice information is not pressed.

[0007]

According to a first aspect of the present invention, there is provided a recording medium having a recording area in which control information is written by using a signal in an audible frequency band, and a controlled device which reads the control information from the recording medium. And a control device body for controlling the control signal, and the signal written in the recording medium is a modem signal obtained by modulating the control information into an analog signal in an audible frequency band.

According to this structure, since the control information is written in the recording medium by using the modem signal obtained by modulating the control information so as to be an analog signal in the audible frequency band, the modem signal is demodulated to decode the control information. The recording density of the control information can be increased while writing the signal in the audible frequency band to the recording medium. That is, the control information can be written in the recording area without occupying a large storage area of the audio information having a limited capacity.

According to a second aspect of the invention, the control device body is

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of the main part, and FIG. 2 shows the specific structure. The present invention controls the controlled device 2 using the control information stored in the recording medium 1. In the present embodiment, as shown in FIG. 2, the recording medium 1 is a video CD 1a and the controlled device 2 is a controlled device 2. The massage machine 2a is illustrated. The video CD 1a has a recording area for recording video information and a recording area for recording 2-channel (that is, stereo) audio information, and the recording area can be divided into up to 99 tracks. The massage machine 2a is a well-known one that loosens muscles by giving various stimuli such as kneading, hitting and pushing to the human body. However, this massage machine 2a is capable of controlling the type and strength of the stimulus, the start time of the stimulus, the end time of the stimulus, etc. by an external signal.

In this embodiment, the control information for controlling the massage machine 2a is written in a part of the recording area for recording the audio information of the video CD 1a.
The type of stimulation and the intensity of stimulation by the massage machine 2a are controlled in synchronization with the reproduction of the image information and the audio information. Specifically, in the recording area of the audio information, for example, the control information is written in the left channel of the second track by using the modem signal.

The modem signal is a signal obtained by modulating digital information into an analog signal in order to transmit the digital information using a telephone line, and various standards are set. In the present embodiment, CCITT V. The modem signal according to the standard of 23 is used. That is, the digital value "0" is modulated into a sine wave of 2100 Hz, and "1" is 1
It is modulated into a 300 Hz sine wave,
Data can be transmitted in the range of 00 bps (bits / sec). Here, modulation is performed so that data is transmitted at 1200 bps, and as is clear from the above frequency range, an analog signal in the audible frequency band is obtained. That is, in the present embodiment, the control information of the massage machine 2a is written in the audio information recording area of the video CD 1a in the form of a modem signal.

Thus, the video CD 1 which is the recording medium 1
massage machine 2a using the control information written in a
In order to control the video CD 1a, a video CD player 3a as a reading device 3 for reading out control information by a modem signal from the recording area of the video CD 1a is required. The modem signal read by the video CD player 3a is input to the signal reproducing unit 4, demodulated, and reproduced as control information which is digital information. Next, in the signal decoding unit 5, the control information is the massage machine 2
The massager 2a which is the controlled device 2 is controlled by decoding what kind of control a is instructed and controlling the control output unit 6 based on the content of the decoded control information. Here, the signal processing unit 8 including the signal reproducing unit 4, the signal decoding unit 5, and the control output unit 6 is provided in the system controller 10 mainly including the microcomputer 7 as shown in FIG.

The system controller 10 is a video CD.
It also has a function of separating the video information and audio information read by the player 3a into a form that can be reproduced by a display device or an audio device. Further, when the user M of the massage machine 2a is equipped with a device for detecting a pulse, a pulse signal processing unit 11 for capturing the physiological information (pulse) as a pulse signal and feeding it back to the control of the massage machine 2a is provided. Prepare Further, a video CD for controlling the video CD 1a and reading the status of the video CD 1a.
The communication processing unit 12 is provided.

0 is stored in the microcomputer 7. When the reading of the modem signal is completed, the system controller 10 controls the video CD 1a to read the information from the recording area (track) in which the video information and the audio information are recorded, and start the reproduction of the video and the audio. At the same time when the reproduction of video and audio is started, the massage machine 2a is controlled according to the control information (control program) of the massage machine 2a obtained by reproducing / decoding the modem signal. In other words, it is possible to synchronize the reproduction of video and audio and the operation of the massage machine 2a. Further, since the control information for controlling the massage machine 2a is the one read before the reproduction of the image or the sound, it is not necessary to read the control information during the reproduction of the image or the sound, and the image is not interrupted without interrupting the image or the sound. And audio can be played. In other words, the audio can be reproduced in stereo. Further, since the transmission rate can be set higher than that of the DTMF signal by using the modem signal, the time required for reading the control information is short, and the time from turning on the power to starting the massage machine 2a is relatively short.

By using the modem signal as described above, the recording density can be increased as compared with the case of writing the control information by using the DTMF signal, and as a result, the voice information becomes monaural or the voice information is written. The amount does not decrease significantly. Moreover, since the modem signal is standardized, when converting the control information into the modem signal or reproducing the control information from the modem signal, the circuit components which are generally popular as standard products can be used, It can be realized at low cost.

In the above-described embodiment, the video CD 1a is illustrated as the recording medium 1. However, it is possible to use the recording medium 1 of another format, and if the random access is not necessary, the video tape is used as the recording medium. Good.
