When audio data is handled, living body information is information about a living body of one or a plurality of music performers (a singer, a music performer of an instrument, and so forth) and listeners such as audience of a concert hall. When video information is handled, living body information is information about living bodies of actors and actresses or information of living bodies of audiences who watch video information that is recorded. These audiences are generally referred to as performer. AV information and living body information recorded on a data recording medium are temporally synchronized. In other words, living body information of the performer is different from living body information of a viewer who reproduces AV information from a data recording medium and watches the reproduced AV information.
In addition to the recording mediums shown in
Living body information of the performer is at least one of a body motion, a biochemical reaction, a brain wave, a magnetoencephalography, an electromyogram, a body surface temperature, perspiration of a skin, a skin resistance, a pulsation, breath, a micro vibration, an electrocardiogram, a heartbeat, and a blood pressure.
In
The sensor 1 generates a detection signal whose amplitude varies in accordance with the breathing exercise. The detection signal is supplied to a low pass filter 2. The low pass filter 2 removes an unnecessary signal component such as noise from the detection signal. It is preferred that the signal generated by the sensor 1 is wirelessly transmitted to the low pass filter 12 so as to prevent a cable from disturbing motion of the performer. An output signal of the low pass filter 2 is supplied to a peak detecting circuit 3 and a level detecting circuit 4. The peak detecting circuit 3 detects a plus peak value and a minus side. The detection signal is nearly a sine wave of which a period from the plus peak value to the minus peak value is an inhalation period and a period from the minus peak value to the plus peak value is an exhalation period.
The detection signal is supplied from the peak detecting circuit 3 to the level detecting circuit 4. The level detecting circuit 4 detects the level of the peak value of the detection signal. The signal that represents the detected level is obtained from an output terminal 7a. The signal obtained from the output terminal 7a represents the depth of breathing. The detection signal of the peak detecting circuit 3 is obtained from an output terminal 7b. A pulse signal at timings of a plus peak value and a minus peak value is obtained as a detection output from the output terminal 7b. The detection output of the output terminal 7b is used as a timing signal.
In addition, the output signal of the peak detecting circuit 3 is supplied as a start signal to a timer 5. In addition, the output signal of the peak detecting circuit 3 is input to a counter 6. An output of the counter 6 is supplied as a stop signal to the timer 5. When the counter 6 has counted up n peaks of the signal, the counter 6 outputs a stop signal to the timer 5. Thus, the timer 5 outputs a detection signal every n peak values. The detection signal that the timer 5 outputs is obtained as a breath interval output from an output terminal 7c. In such a manner, a breath depth signal, a breath timing signal, and a breath interval signal are output from the outputs 7a, 7b, and 7c, respectively.
An output signal of the low pass filter 12 is supplied to a differential amplifier 13. The differential amplifier 13 linearly differentiates the detection signal. The differentiated signal is supplied to a maximum value detecting circuit 14 and a level detecting circuit 15. The maximum value detecting circuit 14 generates a pulse signal at a timing of which the level of the differentiated signal becomes the maximum. The pulse signal is supplied to the level detecting circuit 15. The level detecting circuit 15 detects the level of the differentiated signal as a timing of the pulse signal and outputs the pulse signal to an output terminal 18a. An output signal obtained from the output terminal 18a is a detection signal that represents the intensity of the heartbeat of the performer.
The output of the maximum value detecting circuit 14 is supplied as a start signal to a timer 16. A counter 17 counts up the output of the maximum value detecting circuit 14. When the counter 17 has counted up the maximum value n times, the counter 17 outputs a stop signal to the timer 16. An output signal of the timer 16 is obtained from an output terminal 18b. A detection signal that is obtained from the output terminal 18b represents an interval of heartbeat of the performer.
A blood pressure as another living body information is measured with a cuff that has a sensor that detects variation of a cuff pressure. Waves of electrocardiogram and electromyogram, brain wave, and so forth are measured with electrodes that are placed on the surface of the living body. The electrodes detect an electric signal of the living body. Electricity of the living body is a membrane potential that an exciting cell such as a nerve or a muscle cell generates. The membrane potential depends on variation of permeability of a cell membrane against ions. An impedance such as resistance of a skin can be measured with an electric charge.
A flow of ions due to an electric activity of the living body induces a potential on the outer surface of the body and a magnetic field outside the body. For example, a magnetic field takes place in the brain in accordance with an electric activity in the brain. The magnetic field in the brain can be measured with a magnetic flux gauge having a high sensitivity. The surface temperature of the body can be measured with a temperature detecting sensor at a predetermined portion of the body. A micro vibration is a weak vibration that takes place on the outer surface of the skin. The amplitude of the micro vibration varies in accordance with an emotion, excitement, and so forth of a human. The micro vibration can be detected with a pressure sensor.
In addition, pulsation as another living body information can be measured using ultrasonic waves. In addition, motion of the body can be used as living body information. A light emitting device (that blinks at a predetermined period) is disposed at least one position of the body to be measured. The light emitting device is photographed. The position of the light emitting device is detected on a two-dimensional photographic plane. As a result, the motion of the body can be measured. The timing at which the motion of the body becomes the maximum is measured. Timing is controlled so that when the motion of the body becomes the maximum, reproduction is started.
Next, with reference to
Living body information of the performer, for example a breath signal obtained by the structure shown in
The modulating circuits 23 and 33 obtain digital signals that have the same format as a CD. Output signals of these modulating circuits 23 and 33 are supplied to a region controlling portion 24. The region controlling portion 24 is controlled by a controller 30 composed of a CPU. The region controlling portion 24 supplies address information (sub code of Q channel) separated from a record signal to a servo circuit 29. The address information contains an absolute address corresponding to a record position of the disc. While monitoring addresses of data that is recorded, the controller 30 controls the region controlling portion 24 so that output signals of the modulating circuits 23 and 33 are switched at predetermined addresses. An output signal of the region controlling portion 24 is a record signal. The record signal is supplied to an optical pickup 26 through a recording circuit 25.
The optical pickup 26 records data to a recordable optical disc 27 such as a CD-R (Recordable). The optical disc 27 is placed on a turn table and rotated by a spindle motor 28. The spindle motor 28 is driven and rotated at a constant linear velocity (CLV) under the control of the servo circuit 29.
The servo circuit 29 generates various types of servo drive signals of focus, tracking, thread, and spindle servo drives under the control of an operation command received from the controller 30 and outputs these signals to the spindle motor 28 and the optical pickup 26. The controller 30 controls all the recording apparatus. A display, operation switches, and so forth (not shown) are connected to the controller 30. The optical pickup 26 focus a light beam of a semiconductor laser on a signal side of the optical disc 27 and records data on tracks formed in a concentrically circular shape or a spiral shape on the recordable optical disc 27. All the optical pickup 26 is moved by a thread mechanism.
The optical pickup 26 records data to the recordable optical disc 27 such as a CD-R. The recordable optical disc 27 is placed on the turn table and rotated by the spindle motor 28. The spindle motor 28 is driven and rotated at a constant linear speed (CLV) under the control of the servo circuit 29.
Like the optical disc Ma shown in
As shown in
The optical modulator 42 modulates laser light of the laser 41 in accordance with the record signal. The mastering apparatus radiates the modulated laser light to the glass original 44. As a result, a master on which data is recorded is produced. In addition, the mastering apparatus has servo circuits (not shown) that control the distance between the optical pickup 43 and the glass original 44 so that their distance is kept constant, tracking is controlled, and a rotation driving operation of a spindle motor 45. The glass original 44 is driven and rotated by the spindle motor 45.
A record signal is supplied from a master reader 46 to the optical modulator 42. The master reader 46 reproduces data from the optical disc 27 on which a record signal has been recorded by the recording apparatus described with reference to
The switch 53 is controlled in accordance with a control signal supplied from a file controlling portion 56. The file controlling portion 56 is controlled by a controller 57 composed of a CPU. AV information and living body information that are logically divided namely they are converted into different files are selected by the switch 53 and output from an output terminal c thereof.
An output of the switch 53 is supplied to a modulating circuit 59 through an error correction code encoder 58. After an error correction code encoding process is performed for the output data of the switch 53, the encoded data is modulated. The modulated data is supplied to a recording circuit 60. The recording circuit 60 outputs a record signal. The record signal is recorded on an optical disc 61a. In this case, an optical pickup (not shown) is used. When the record signal is recorded to a hard disk drive 61b or an optical card 61c rather than the optical disc 61a, a structure similar to the structure of the signal process for the optical disc 61a can be used.
Next, with reference to
An optical disc 71 is placed on a turn table and rotated by a spindle motor 72. The spindle motor 72 is driven and rotated at a constant linear velocity (CLV) under the control of a servo portion 73. The servo portion 73 generates various types of servo drive signals for focus, tracking, thread, and spindle servo drives in accordance with a focus error signal, a tracking error signal, and an operation command received from a controller 78 and outputs these generated signals to the spindle motor 72 and an optical pickup 74. The controller 78 controls all the reproducing apparatus. A display, operation switches, and so forth are connected to the controller. The optical pickup 74 focuses a light beam of a semiconductor laser on a signal side of the optical disc 71 and traces tracks formed in a concentrically circular shape or spiral shape on the optical disc 71. All the optical pickup 74 is moved by a thread mechanism.
An output of the optical pickup 74 is supplied to a synchronization detector 76 through an RF amplifier 75. An output of the synchronization detector 76 is supplied to a sub code detecting circuit 77. The synchronization detector 76 detects a frame synchronization signal for each EFM frame of a reproduction signal. The sub code detecting circuit 77 detects a Q channel of a sub code and detects an address signal of the Q channel.
A servo signal is supplied from the RF amplifier 75 to the servo portion 73. The sub code detected by the sub code detecting circuit 77 is supplied to the servo portion 73, the controller 78, and a region controlling portion 85 that will be described later.
An output signal of the sub code detecting circuit 77 is supplied to for example an EFM demodulator 79 and a TOC reading circuit 83. An output of the demodulator 79 is supplied to an error correcting circuit 80. The error correcting circuit 80 corrects an error of the output of the demodulator 79. When necessary, the error correcting circuit 80 interpolates an error that cannot be corrected. The error correcting circuit 80 outputs reproduction data to an input terminal of a switch 81. The switch 81 outputs a PCM audio signal as reproduced AV information and reproduced living body information to output terminals 82a and 82b, respectively.
TOC recorded in a lead-in area of the optical disc 71 contains the same information as the TOC of a CD and address information of a boundary position of a recording region of living body information and a recording region of AV information. When the optical disc 71 is loaded into the reproducing apparatus, the lead-in area is read as a reading position. As a result, the TOC is read. Like the conventional CD, the TOC reading circuit 83 causes the total number of music programs, the total play time, and so forth to be displayed in accordance with the TOC that has been read. When living body information and AV information have been recorded on the optical disc, a region information detecting circuit 84 detects the address information of the boundary thereof.
The address information of the boundary of the two regions detected by the region information detecting circuit 84 is supplied to the region controlling portion 85. A reproduction address is supplied from the sub code detecting circuit 77 to the region controlling circuit 85. The region controlling portion 85 is connected to the controller 78. The region controlling portion 85 compares the reproduction address corresponding to the reproduction position of the optical disc 71 and the address information of the boundary detected by the region information detecting circuit 84 and outputs a control signal that causes the switch 81 to change the switch position to another switch position when they match. Thus, when data is reproduced from the inner periphery of the optical disc 71, a PCM audio signal is reproduced from a session P1 and output to an output terminal 82a. Thereafter, living body information is reproduced from a session P2 and output to an output terminal 82b.
The foregoing reproducing apparatus successively reads data from the sessions of the optical disc 71 with one optical pickup. Alternatively, living body information may be pre-read and stored in a memory. Alternatively, AV information and living body information may be simultaneously reproduced with two pickups.
Video information and audio information of reproduction AV information obtained from the output terminal 82a are reproduced by a display, a projector, or the like and a speaker, respectively. Living body information of the performer obtained from the output terminal 82b is reproduced as at least one of a sound, a picture, and a vibration that vary. For example, when a chair on which the listener sits vibrates in accordance with an input signal, the chair is vibrated in accordance with living body information.
Alternatively, reproduction AV information may be affected in accordance with living body information of the performer.
The breath depth signal is input to a comparator 93. A reference signal is supplied from a controller 94 to the comparator 93. The comparator 93 compares the breath depth signal with the reference signal. The breath interval signal is input to a comparator 96. A reference signal is supplied from the controller 94 to the comparator 96. The comparator 96 compares the breath interval signal with the reference signal. The reference signals are stored in a database composed of a RAM 97. The controller 94 selectively reads a reference signal from the RAM 97 and supplies the reference signal to the comparator 93. Likewise, a reference signal supplied to the comparator 96 is read from the RAM 97 by the controller 94.
An example of a reference signal stored in the RAM 97 is standard data about the performer. When AV information is music, a plurality of sets of standard data is pre-stored in accordance with a conductor, singer (male or female), genre of music, and so forth. Standard data is automatically selected in accordance with a switch operation of the viewer/listener or identification information recorded in the TOC.
The comparator 93 generates a binary comparison output that represents whether or not the breath depth signal of the performer is larger than standard data. Likewise, the comparator 96 generates a binary comparison output that represents whether the breath interval signal of the performer is larger than standard data. Instead of the comparators, dividing circuits may be disposed so that a signal of breath information is standardized in accordance with a reference signal. In this case, a normalized output is generated instead of a binary output.
The PCM audio signal that is input from the input terminal 91 to a level adjusting circuit 98. The level adjusting circuit 98 controls the level of the PCM audio signal in accordance with the comparison output of the comparator 93. When the breath depth signal represents that the breathing becomes deep, the level adjusting circuit 98 increases the level of the PCM audio signal. An output signal of the level adjusting circuit 98 is supplied to a tempo adjusting circuit 99.
The tempo adjusting circuit 99 controls the tempo of the PCM audio signal in accordance with the comparison output of the comparator 96. For example, the breath interval signal and the tempo are synchronized. When the breath intervals become short, the tempo adjusting circuit 99 increases the tempo. An output signal of the tempo adjusting circuit 99 is supplied to an effecter 100.
The effecter 100 is controlled in accordance with output signals of the comparators 93 and 96. The effecter 100 controls a frequency component of the PCM audio signal in accordance with the breath depth and the breath intervals. An output signal of the effecter 100 is supplied to a noise adding circuit 101.
The noise adding circuit 101 is controlled by the output signals of the comparators 93 and 96. A level noise and an interval noise of the breath depth and the breath intervals are detected. The noise adding circuit 101 adds noises in accordance with the detected noises. The noises are 1/fn noises (where n is any integer larger than 0). The level of the PCM audio signal is controlled in accordance with the level noise. The tempo of the PCM audio signal is controlled in accordance with the interval noise. An output signal is obtained from the noise adding circuit 101. The structure shown in
Next, another embodiment of the present invention will be described. According to the present embodiment, when the AV information is recorded or transmitted, AV information is frame-segmented, block-segmented, or packetized. Living body information is contained in each transmission unit.
The segmented data extracting circuit 113a extracts AV data for a data amount corresponding to a segmented data unit for example a frame. The segmented data extracting circuit 113b extracts living body data for a data amount in accordance with a segmented data unit for example a frame. Output data of the segmented data extracting circuits 113a and 113b is supplied to a mixing circuit 114. As shown in
An output signal of the mixing circuit 114 is supplied to a modulating circuit 116 through an error correction code encoder 115. Data that has been encoded with an error correction code and modulated is supplied to a recording circuit 117. A record signal of the output of the recording circuit 117 is recorded on an optical disc 118a. In this case, an optical pickup (not shown) is used. A structure similar to that for the signal process for the optical disc 118a can be used to record a record signal to a hard disk drive 118b or an optical card 118c.
Next, with reference to
An optical disc 121 is placed on a turn table and rotated by a spindle motor 122. The spindle motor 122 is driven and rotated at a constant linear velocity (CLV) under the control of a servo portion 123. The servo portion 123 generates various types of servo drive signals for focus, tracking, thread, and spindle servo drives in accordance with a focus error signal, a tracking error signal, and an operation command received from a controller (not shown) and outputs these signals to the spindle motor 122 and an optical pickup 124. The optical pickup 124 focuses a light beam of a semiconductor laser on a signal side of the optical disc 121 and traces tracks formed in a concentrically circular shape or spiral shape on the optical disc 121. All the optical pickup 124 is moved by a thread mechanism.
An output of the optical pickup 124 is supplied to the synchronization detector 126 through an RF amplifier 125. An output of the synchronization detector 126 is supplied to an address detecting circuit 127. The synchronization detector 126 detects a synchronization signal such as a frame synchronization signal of a reproduction signal. The address detecting circuit 127 detects an address signal of the optical disc 121. A servo signal that is output from the RF amplifier 125 is supplied to the servo portion 123. An address signal detected by the address detecting circuit 127 is supplied to the servo portion 123 and a controller (not shown).
An output signal of the address detecting circuit 127 is supplied to a demodulator 128. An output of the demodulator 128 is supplied to an error correcting circuit 129. The error correcting circuit 129 corrects an error of the reproduction data. When necessary, the error correcting circuit 129 interpolates an error that cannot be corrected. The reproduction data that is output from the error correcting circuit 129 is supplied to a frame disassembling circuit 130. The frame disassembling circuit 130 separates one frame into AV information and living body information and outputs them to output terminals 131 and 132, respectively. When the reproduction data is a packet or a block, the frame disassembling circuit 130 separates the packet or block into the output terminals 131 and 132, respectively.
Like the foregoing embodiment, living body information of the performer that is obtained from the output terminal 132 is reproduced as at least one of a sound, a picture, and a vibration that vary. When a chair on which the viewer/listener sits vibrates in accordance with an input signal, the chair is vibrated in accordance with living body information. Alternatively, as described with reference to
The segmented data extracting circuit 143a extracts AV data for a data amount corresponding to a segmented data unit for example a packet.

An output signal of the multiplexer 144 is supplied to a data transmitting circuit 145. The data transmitting circuit 145 performs an error correction code encoding process, a modulating process, and so forth for the output signal of the multiplexer 144. A transmission signal that is output from the data transmitting circuit 145 is supplied to a transmission antenna 146a and transmitted as a radio wave or to a network 146b.
Next, with reference to
Reception data received through the receiving antenna 150a or the network 150b is supplied from an input terminal 151 to a data receiving circuit 152. The data receiving circuit 152 performs a demodulating process, an error correcting process, and so forth for the reception data and obtains reception data of which a packet of AV information and a packet of living body information are multiplexed on time division basis.
The reception data is supplied to a packet separating circuit 153. The packet separating circuit 153 separates data packets from the reception data. The separated data packets are supplied to a packet disassembling circuit 154. The packet disassembling circuit 154 disassembles the data packets into packets of AV information and packets of living body information. AV information is output to one output terminal 155. Living body information is output to another output terminal 156. The reception AV information is reproduced as a stream by for example a personal computer.
Like the foregoing embodiment, living body information of the performer is reproduced as at least one of a sound, a picture, and a vibration that vary. In addition, as described with reference to
Although the present invention has been shown and described with respect to a best mode embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions, and additions in the form and detail thereof may be made therein without departing from the spirit and scope of the present invention. For example, the brightness of lighting may be varied in accordance with living body information of the performer. Alternatively, the level, tempo, and so forth of a very low frequency sound may be controlled in accordance with living body information of the performer. In addition, living body information of an actor in a leading role of a stage or a movie or living body information of a pantomime performer may be detected and recorded or transmitted along with a picture thereof.
