Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      This invention relates to an image-recording system that records images and sound as well as attributes related to images or sound.  
      2. Related Art  
      In recent years, digital-broadcast systems have been put into use in which digitized television signals are transmitted by way of artificial satellites such as broadcast satellites or communications satellites, and then those signals are received in private homes in order to view television programs. In this kind of system, it is possible to maintain a plurality of broadcast channels, so it is possible to broadcast a very large number of programs.  
      In this kind of system, program information that indicates the broadcast contents of a plurality of programs, for example data (hereafter referred to as meta data) in which specified information is included for that broadcast-contents data such as program arrangement information (hereafter referred to as SI (Service Information)) in a BS (Broadcast Satellite) digital broadcast or CS (Communication Satellite) digital broadcast, is transmitted together with the video or audio information (hereafter referred to as video and audio data) of the TV programs from the satellite to the television-broadcast-receiving apparatus in each home.  
      Also, each television-broadcast-receiving apparatus that receives broadcast-contents data broadcast by this system outputs the video and audio data to the TV display and extracts the meta data, then uses that meta data to provide various services to the user.  
      On the other hand, with the development of imaging apparatuses such as compact digital cameras or digital video cameras and the like, it has become common for users to take digital moving or still images of objects such as scenery or people.  
      For this kind of imaging apparatus, there is technology in which together with filming and recording image data that includes audio, a transmitter is attached to the object being filmed, and the imaging apparatus correlates the Identification information (hereinafter, referred to as ID information) of the object that is transmitted by this transmitter (meta data) with the video data and records its. More specifically, this imaging apparatus is such that it reads the blinking pattern of a data tag that blinks and is attached to the object being filmed, then multiplexes that blinking pattern with the video data as ID information and records it. (For example, refer to Japanese Unexamined Patent Application Publication No. 2001-320702)  
      However, in the broadcast system described above, the meta data indicates only attributes for the entire contents data such as the genre or broadcast date of the contents data to which that meta data is attached. Also, in the imaging apparatus described above, the ID information is simply correlated with the video data, and attribute information for the object being filmed is not particularly linked to and recorded with the video data.  
      Also, in this broadcast system or with this imaging apparatus, in the case of video data having a story such as broadcast contents data, it is not possible to indicate attributes for each frame or each scene, so the contents of video data having a story cannot be analyzed based on attributes for each frame or each scene.

      The process for verification by the data-sending/receiving unit  112  (hereafter referred to as the verification process) and its operation will be explained in detail later.  
      The beam-receiving unit  113  is such that it receives the filming-range-setting beam (described later) that is sent from the imaging-camera apparatus  120 , and when this filming-range-setting beam is received, outputs a notification to the control unit  116  for the data-transmission apparatus that the filming-range-setting beam has been received.  
      The object microphone  114  is such that it is used when determining whether or not there is speech by the object to which the data-transmission apparatus  110  is attached, and it picks up the speech from that object and outputs the picked up sound to the speech-judgment unit  115  as an audio signal.  
      The audio signal that is output from the object microphone  114  is input to the speech-judgment unit  115 , and this speech-judgment unit  115  determines whether or not there is speech from the object to which the data-transmission apparatus  110  is attached based on whether or not there is an input audio signal, and then outputs the judgment results to the control unit  116  for the data-transmission apparatus.  
      The control unit  116  for the data-transmission apparatus mainly comprises a central processing unit (CPU) and a memory, and when sending or receiving various data, it performs overall control of the general functions.  
      Particularly, in this embodiment, the control unit  116  for the data-transmission apparatus receives the image-range-setting beam that is input from the beam-receiving unit  113  described above, and generates object data based on the judgment result by the speech-judgment unit  115  and attribute data that is stored in the data-memory unit  111 , and then outputs that generated object data  22  to the imaging-camera apparatus  120  by way of the data-sending/receiving unit  112 .  
      More specifically, when a notification is input that an filming-range-setting beam has been received by the beam-receiving unit  113 , the control unit  116  for the data-transmission apparatus determines that the object is in the filming range, and when a notification that a filming-range-setting beam has been received by the beam-receiving unit  113  is not input, it determines that the object is not in the filming range, and then generates filming-range information indicating whether or not the object is in the filming range. Also, based on the judgment results input from the speech-judgment unit  115 , the control unit  116  for the data-transmission apparatus generates speech information indicating whether or not there is current speech from the object.  
      Also, as shown in  FIG. 3 , the control unit  116  for the data-transmission apparatus generates object data based on filming-range information and speech information generated as described above, as well as based on attribute data acquired from the data-memory unit  111  and comprising object ID, name information, age information, occupation information, gender information and personality information, and outputs that generated object data  22  to the imaging-camera apparatus  120 .  
      On the other hand, according to an instruction from the imaging-camera apparatus  120 , the control unit  116  for the data-transmission apparatus sends specified data to the data-sending/receiving unit  112  for verifying that the data-transmission apparatus  110  is able to access the imaging-camera apparatus  120 .  
      Next,  FIG. 5  will be used to explain the construction of the imaging-camera apparatus of the editing system of this embodiment.  FIG. 5  is a block diagram showing the construction of the imaging-camera apparatus of this embodiment.  
      As shown in  FIG. 5 , the imaging-camera apparatus  120  of this embodiment comprises: a camera unit  121  having a camera lens and that acquires an image by way of that camera lens using an electronic signal; a camera-control unit  122  that controls the camera unit  121 ; a beam-projection unit  123  that projects a filming-range-setting beam in a preset range; an operation unit  124  that is used for filming in the field of view of the camera lens; a video-data-conversion unit  125  that converts the electronic signal of the images acquired by the camera unit  121  (hereafter referred to as the image signal) to video data having a preset format; a pick-up microphone  126  that picks up sound such as speech from the object being filmed; an audio-data-conversion unit  127  that converts the audio signal acquired by the pick-up microphone  126  to audio data having a preset format; a data-communication unit  128  that receives object data  22  that contains the attribute data that is sent from the data-transmission apparatus  110 , and sends or receives various data related to receiving of that object data  22 ; a data-generation unit  129  that generates a video stream based on the audio data and object data  22 ; a data-recording unit  130  in which the generated video stream  1  is recorded; a system-control unit  131  that controls each unit, and ROM/RAM  132  that is used when performing each process, and where each of the units is connected via a bus  132 .  
      Here, for example, the camera unit  121  of this embodiment forms the filming means of this invention, and the beam-projection unit  123  forms the projection means of the invention. Moreover, for example, the video-data-conversion unit  125  and audio-data-conversion unit  127  of this embodiment form the acquisition means and data-acquisition means of this invention, and the pick-up microphone  126  forms the pick-up microphone  126  of the invention. Furthermore, for example, the data-communication unit  128  forms the receiving means of this invention, and the data-recording unit  130  of this embodiment forms the recording means of the invention.  
      The camera unit  121  comprises an imaging element (hereafter referred to as a CCD (Charge Coupled Device)) that performs photoelectric conversion for each picture element of the image formed by the camera lens, and a buffer for temporarily storing the signal for each picture element for which photoelectric conversion was performed, and it forms an image of the field of view formed by focusing light by the camera lens and performs photoelectric conversion of the formed image of the field of view, then stores it temporarily in the buffer, and outputs a video signal having a specified format for each frame (described later) to the video-data-conversion unit  125 .  
      This camera unit  121  is mechanically connected to the finder F shown in  FIG. 1 , and when the user looks through the finder F, it is possible to check the image of the field of view formed by the camera lens.  
      During the imaging process, or in other words, when recording video data and corresponding audio data in the data-recording unit  130 , the beam-projection unit  123  projects a filming-range-setting beam on the range that corresponds to the filming range for which filming is performed by the camera unit  121  according to control by the camera-control unit  122 .  
      More specifically, this beam-projection unit  123  is such that it projects a laser beam that opens up in a conical shape along the filming range of the image formed by the camera lens.  
      In order for the imaging-camera apparatus  120  to take precise images of the field of view desired by the user, the camera-control unit  122  performs control of the camera lens and all other parts of the camera unit that are not shown in the figures based on instructions from the user that were input by way of the operation unit  124 , and together with controlling the camera unit  121 , it controls the beam-projection unit  123  such that it projects the filming-range-setting beam on the range for which an image is to be formed by the camera lens.  
      The operation unit  124  comprises: a plurality of keys such as control buttons for controlling the camera unit  121 , a confirmation button for confirming and selecting arbitrary settings, selection buttons and number keys, and when buttons or keys are pressed, it outputs the signal corresponding to that button or key to the camera-control unit  122  or system-control unit  131 .  
      In this embodiment, when this operation unit  124  is used to perform settings and controls, the control contents or setting contents by the operation unit  124  are displayed on the screen of the finder F.  
      The video signal output from the camera unit  121  is input to the video-data-conversion unit  125 , and this video-data-conversion unit  125  converts the input video signal to a digital signal for each frame, and converts it to video data having a specified format, then outputs the converted video data to the data-generation unit  129 .  
      The pick-up microphone  126  is such that it picks up speech spoken by the object and the sound surrounding the imaging-camera apparatus  120 , and converts the picked up sound to an electronic signal (hereafter referred to as the audio signal) and outputs it to the audio-data-conversion unit  127 .  
      The audio signal output from the pick-up microphone  126  is input to the audio-data-conversion unit  127 , and this audio-data-conversion unit  127  converts the input audio signal to audio data corresponding to the video data for each frame having a specified format, and then outputs the converted audio data to the data-generation unit  129 .  
      The data-communication unit  128  is connected to the antenna AT, and by performing data communication with the data-transmission apparatus  110  using a specified communications format such as wireless tag, Bluetooth (registered trademark) or the like, sends or receives object data  22  containing attribute data similar to the data-transmission apparatus  110 .  
      Particularly, the data-communication unit  128  is such that it receives encoded object data  22  and decodes that received object data, then outputs specified object data  22  to the data-generation unit  129 .  
      More specifically, the data-communication unit  128  determines whether or not the object ID for each of the encoded object codes  22  is different than the object ID registered for the previous frame, and when there is object code  22  that has an object ID that is different than the object ID registered for the previous frame, it outputs that object code  22  to the data-generation unit  129 .  
      At this time, when there is no object ID for any of the object data  22  that is different than the object ID registered for the previous frame, the data-communication unit  128  does not output any object data  22  to the data-generation unit  129 , and outputs a notification that the object code  22  is the same as that of the previous frame.  
      Also, when sending or receiving object data  22  to or from the data-transmission apparatus  110 , as in the case of the control-unit  116  for the data-transmission apparatus  110 , the data-communication unit  128  is such that it sends or receives specified data for verification of the data communication with the data-transmission apparatus  110 .  
      The process for verifying communication with the data-sending/receiving unit  112  of this embodiment (hereafter referred to as the verification process) and its operation will be explained in detail later.  
      Video data, audio data and object data are input to the data-generation unit  129 , and based on the input video data, audio data and object data  22 , this data-generation unit  129  generates a video stream  1  having a specified format such as MPEG (Motion Picture Experts Group) or DV (Digital Video), and outputs the generated video stream  1  in order to the data-recording unit  130 .  
      More particularly, as mentioned above, this data-generation unit  129  multiplexes the video data and audio data for each frame (hereafter this multiplexing will be referred to as the multiplexing process), and together with generating preset frame-group data  10  of about 1 to 15 frames, it generates a video stream  1  based on the generated frame-group data  30 .  
      For example, as described above, the data-generation unit  129  of this embodiment is such that it generates frame-group data  10  for a frame group of about 1 to 15 frames that comprises: a header section  11  in which specified data is recorded that is related to the contents data recorded in the frame-group data  10 ; a contents-data section  12  that contains video data and audio data for each frame; and a meta-data section  13  that contains the object data  22 .  
      The data-recording unit  130 , for example, comprises a hard disc (hereafter referred to as HD), and the video stream  1  that was generated by the data-generation unit  129  is input into this data-recording unit  130 .  
      The system-control unit  131  mainly comprises a central processing unit (CPU), and when sending or receiving various data, or when recording video data and audio data, it performs overall control of general functions.  
      Particularly, when receiving object data  22 , the system-control unit  131  controls the data-communication unit  128 , and performs control of receiving the object data  22  and control of the verification process, and when recording video data and audio data, it performs control of recording the data, or in other words, performs control of generating and recording the video stream  1 .  
      The verification process by the system-control unit  131  of this embodiment, and the process of recording video data and audio data (hereafter referred to as the recording process) will be explained in detail later.  
      Next,  FIG. 6  will be used to explain the control by the system-control unit in the verification process of the imaging-camera apparatus of this embodiment, and the operation of each part.  
       FIG. 6  is a flowchart showing the control by the system-control unit in the verification process of the imaging-camera apparatus of this embodiment, and the operation of each part.  
      First, after the system-control unit  131  turns ON the power to the imaging-camera apparatus  120  by way of the operation unit  124 , or after an operation is performed using the operation unit  124  to notify that the data-transmission apparatus  110  has been recognized, and after that notification that the data-transmission apparatus  110  has been input to the system-control unit  131  (step S 11 ), the system-control unit  131  detects by way of the data-communication unit  128  whether or not there is power to each data-transmission apparatus  110  (step S 12 ).  
      That is, after the power has been turned ON, the data-transmission apparatus  110  sends a signal notifying that the power to the data-transmission apparatus  110  has been turned ON (hereafter this is referred to as the power-ON signal), and sends ID information to identify it from other data-transmission apparatuses  110 ; so by receiving the power-ON signal and the ID information, the system-control unit  131  detects whether or not the sent ID information is from a data-transmission apparatus  110  that is not a data-transmission apparatus  110  that has already been verified.  
      At this time, when the system-control unit  131  detects a data-transmission apparatus  110  having ID information for which verification has not yet been performed, it goes to the process of step S 13 , and when it detects a data-transmission apparatus  110  having ID information for which verification has already been performed, or when it does not receive any ID information from any data-transmission apparatus  110 , it stops the verification process and ends this operation.  
      When the system-control unit  131  detects only data-transmission apparatuses  110  having ID information for which verification has already been performed, or when it does not receive ID information from any data-transmission apparatus  110 , it displays a notification of that on the monitor in the finder F.  
      Next, when the system-control unit  131  detects an unverified data-transmission apparatus  110 , that system-control unit  131  performs the following operation for each data-transmission apparatus  110 . When the system-control unit  131  detects a plurality of data-transmission apparatuses  110 , it performs the following verification process of the data-transmission apparatuses  110  in the order of the most recent ID information.  
      First, the system-control unit  131  sends an instruction to the data-transmission apparatus  110  via the data-communication unit  128  to send various data for performing the verification process to the system-control unit  131  (step S 13 ).  
      At this time, based on the sent instruction, the data-transmission apparatus  110  that received that instruction to send data for performing the verification process encodes the various internally stored data for performing the verification process, and sends it to the imaging-camera apparatus  120 .  
      Next, after the system-control unit  131  receives data from the data-transmission unit  110  by way of the data-communication unit  128  in order to perform the verification process, it decodes that data, and as described above, performs the verification process to check whether or not this data-transmission apparatus  110  can be verified (step S 14 ), and when it is determined that this data-transmission apparatus  110  cannot be verified, the system-control unit  131  stops the verification process for verifying that data-transmission apparatus  110  and goes to the process of step S 15 .  
      When the system-control unit  131  determines that verification is not possible, it displays a notification of that on the monitor located in the finder F.  
      On the other hand, when the system-control unit  131  determines that this data-transmission apparatus  110  can be verified, the system-control unit  131  encodes a notification that the data-transmission apparatus  110  can be notified, and encodes various internally stored data for performing the verification process, then sends that data to the data-transmission apparatus  110 , and waits for data to be sent from the data-transmission apparatus  110  (step S 15 ).  
      At this time, after the data-transmission apparatus  110  receives the data from the imaging-camera apparatus  120  for performing the verification process, it decodes that data, and as described above, performs the verification process of whether or not that imaging-camera apparatus  120  can be verified, and when the data-transmission apparatus  110  determines that the imaging-camera apparatus  120  cannot be verified, it stops the verification process and sends a notification to that imaging-camera apparatus  120  that that imaging-camera apparatus  120  cannot be verified. On the other hand, when the data-transmission apparatus  120  determines that that imaging-camera apparatus  120  can be verified, it sends a notification that verification is possible.  
      Next, the system-control unit  131  determines whether or not the data received by the system control unit  131  by way of the data-communication unit  128  is a notification that verification is not possible, or a notification that verification is possible (step S 16 ), and when a notification that verification is not possible is received, the system-control unit  11  stops the verification process for that data-transmission apparatus  110  and goes to the process of step S 15 .  
      When the system-control unit  131  receives a notification that verification is not possible, it displays that notification on the monitor located in the finder F.  
      On the other hand, when the system-control unit  131  receives a notification that verification is possible, it sends an instruction to that data-transmission apparatus  110  to send the object data  22  generated by the data-transmission apparatus  110  (step S 17 ).  
      Finally, the system-control unit  131  determines whether or not there are still data-transmission apparatuses  110  for which verification has not yet been performed (step S 18 ), and when there are data-transmission apparatuses  110  for which verification has not yet been performed, it goes to the process of step S 12 , and when there are no data-transmission apparatuses  110  for which verification has not yet been performed, it ends this operation.  
      Next,  FIG. 7  will be used to explain the control by the system-control unit in the recording process of the imaging-camera apparatus of this embodiment, and the operation of each part.  
       FIG. 7  is a flowchart showing the control by the system-control unit in the recording process of the imaging-camera apparatus of this embodiment, and the operation of each part.  
      Here it will be presumed that all of the attribute data is already stored in the data-transmission apparatus  110 , that the data-transmission apparatus  110  has already been verified by the verification process described above, and that the object data  22  has been sent to the imaging-camera apparatus  120 .  
      First, when the user controls the operation unit  124  to give an instruction to the system-control unit  131  to start filming, the system-control unit  131 , based on an internally generated reference clock, determines whether or not the time amount for one frame has elapsed (step S 21 ), and when it determines that the time amount for one frame has not yet elapsed, it repeats that process, and when it determines that the time amount of for one frame has elapsed, then it executes the following process for each frame.  
      At this time, the camera unit  121  performs photoelectric conversion of the image of the field of view formed by the CCD and lens for each picture element, and stores the signal of the photo-electrically converted picture elements in the internal buffer.  
      Next, when the system-control unit  131  determines, based on the reference clock, that the amount of time of one frame has elapsed, it has the camera unit  121  output the signal for each of the pixels to the video-data-conversion unit  125 , and has the video-data-conversion unit  125  and the audio-data-conversion unit  127  execute video-data processing and audio-data processing, respectively, and to output both the processed video data and audio data to the data-generation unit  129  (steps S 22  to S 26 ).  
      More specifically, the video-data-conversion unit  125  samples the input video signal using a specified period and converts it to a digital signal (step S 22 ), and then encodes the converted digital signal into a specified format and outputs it to the data-generation unit  129  (step S 23 ). Also, the audio-data-conversion unit  127  samples the input audio signal using a specified period and converts it to a digital signal (step S 24 ), and then encodes the converted digital signal into a specified format and outputs it to the data-generation unit  129  (step S 25 ). Furthermore, as described above, the system-control unit  131  has the data-generation unit  129  multiplex the video data and audio data for that frame (multiplexing process (step S 26 )).  
      On the other hand, the system-control unit  131  has the data-communication unit  128  receive each object data  22  (step S 27 ) and determine whether or not the object ID in each received object data  22  is different than the object ID registered for the previous frame (step S 28 ) and when the object data  22  has an object ID that is different than the object ID registered for the previous frame, it has the data-communication unit  128  output that object data  22  to the data-generation unit  129  (step S 29 ).  
      At this time, when the data-communication unit  128  determines that there is no object data having an object ID that is different than the object ID registered for the previous frame, the data-communication unit  128  does not output any object data  22  to the data-generation unit  129 , and outputs a notification to the data-generation unit  129  that the object data is the same as that of the previous frame. Also, the system-control unit  131  performs the video-data processing and audio-data processing at the same time, and performs the video processing and audio processing, including the process of generating the video stream  1 , at the same time as the process of acquiring object data  22 .  
      Next, the system-control unit  131  uses that frame of the generated video stream  1  to determine whether or not that frame has reached the specified number of frames of the frame group to which the frame belongs (step S 30 ).  
      When it is determined using the frame of contents data generated by the data-generation unit  129  that the frame has not reached the specified number of frames for the frame group, the system-control unit  131  goes to the process of step S 21 , and has the data-generation unit  129  generate contents data for the next frame.  
      On the other hand, when it is determined using the frame of the contents data generated by the data-generation unit that that frame has reached the specified number of frames of the frame group, the system-control unit  131  has the data-generation unit  129  generate a header section  11  from data other than the object data  22  as described above, and based on each object data  22 , generate a meta-data section  13 , and then based on the contents data for each frame and that meta-data section  13  and header section  11 , generate frame-group data  10  (step S 31 ).  
      When there is no object data in any of the object data  22  that is different than the object data registered for the previous frame, and a notification is input to the data-generation unit  129  that the object data  22  is the same as that of the previous frame, the data-generation unit  129  generates the meta-data section  13  for that frame based on the object data  22  of the previous frame.  
      Next, the system-control unit  131  has the data-generation unit  129  output the generated frame-group data  10  to the data-recording unit  130 , and records that frame-group data  10  in the data-recording unit  130  (step S 32 ).  
      Finally, based on other control from the operation unit  124 , the system-control unit  131  determines whether the filming process has ended (step S 33 ), and when it determines that the filming process is continuing, it goes to the process of step S 21 , and when it determines that the filming process has ended, it ends this operation.  
      In the embodiment described above, the image-recording system  100  is an image-recording system  100  that records at least the sound generated from a sound source or video acquired by filming a target object as contents data, and comprises: a data-transmission apparatus  110  that is attached to at least the sound source or the object, and sends object data  22  that indicates the attributes of at least that sound source or that object; and an imaging-camera apparatus  120  that correlates and records at least the sound generated from the sound source or acquired video of the object to which the data-transmission apparatus  110  is attached.  
      With this construction, the image-recording system  100  of this embodiment correlates the object data  22 , which is sent from the data-transmission apparatus  110  that is attached to the sound source or object, with the sound generated from the sound source or the video taken of the object, and records it.  
      Also, when recording the sound source or object, the object data  22  of that sound source or object can be correlated with the sound source or object and recorded, so when editing the recorded sound source or video of the object, such as when analyzing the recorded video story, or when reproducing a summary that accurately provides the contents while at the same time shortens the reproduction time of the recorded video, it is possible to perform recording or reproduction based on that object data  22 .  
      The image-recording system  100  of this embodiment is constructed such the imaging-camera apparatus  120  comprises: a camera unit  121  that films an object; a video-data-conversion unit  125  that acquires images of the field of view of the filmed object as contents data; a data-communication unit  128  that receives object data  22  that is sent from the data-transmission apparatus  110 ; and a data-recording unit  130  that records the acquired video data, and correlates and records the received object data  22  with the recorded video data.  
      With this construction, the image-recording system  100  of this embodiment together with acquiring the image of the field of view of the object as contents data, receives object data  22  sent from the data-transmission apparatus  110 , and when recording the acquired video data, correlates and records the received object data  22  with that video data to be recorded.  
      Also, when recording the object, it is possible to correlate and record the object data  22  for that object with speech that is made by the object, so when editing the recorded sound source or the video of the object, such as when analyzing the recorded video story, or when reproducing a summary that accurately provides the contents while at the same time shortens the reproduction time of the recorded video, it is possible to perform recording or reproduction based on that object data  22 .  
      Moreover, the image-recording system  100  of this embodiment is constructed such that when the video-data-conversion unit  125  of the imaging-camera apparatus  120  acquires the images of the field of view of the object as video data comprising a plurality of frames, the object data  22  is correlated with the video data for each frame and recorded in the data-recording unit  130 .  
      With the image-recording system  100  of this embodiment having this construction, object data  22  is correlated and recorded with the video data, so when editing the recorded sound source or the video of the object, such as when analyzing the recorded video story, or when reproducing a summary that accurately provides the contents while at the same time shortens the reproduction time of the recorded video, it is possible to perform recording or reproduction based on that object data  22 .  
      Furthermore, the image-recording system  100  of this embodiment is constructed such that the imaging-camera apparatus  120  comprises: a pick-up microphone  126  that picks up the sound generated from the sound source; an audio-data-conversion unit  127  that acquires the sound picked up by the microphone as contents data; a data-communication unit  128  that receives the object data  22  sent from the data-transmission apparatus  110 ; and a data-recording unit  130  that together with recording the acquired audio data, correlates and records the received object data  22  with that audio data to be recorded.

      Also, as in the first embodiment, the meta-data section  33  comprises frame-meta data  40  for each frame that contains information  41  of the number of object data in each frame of the frame group and that object data  42 .  
      On the other hand, as shown in  FIG. 9 , each object data  22  contains attribute information such as rumbling information that indicates whether or not rumbling or sound is output from the instrument to which the data-transmission apparatus is attached, performer ID that identifies the performer from other performers, performer name information the indicates that performer&#39;s name, age information that indicates the performer&#39;s age, and instrument name information that indicates the instrument name.  
      Next,  FIG. 10  will be used to explain the construction of the data-transmission apparatus of this embodiment.  FIG. 10  is a block diagram showing the construction of the data-transmission apparatus of this embodiment.  
      The data-transmission apparatus  210  of this embodiment comprises: a data-memory unit  111  that stores the attribute data mentioned above; a data-sending/receiving unit  112  that is connected to an antenna AT and sends or receives object data  42 , as well as sends or receives various data related to the sending or receiving of that object data  42 ; an instrument microphone  211  that acquires sound from the instrument to which the data-transmission apparatus  210  is attached; an output-judgment unit  212  that, based on the sound input to the instrument microphone  211 , determines whether or not there is rumbling of the instrument or sound output from the instrument; and a data-transmission-apparatus-control unit  116  that controls each unit.  
      The instrument microphone  211  and output-judgment unit  212  of this embodiment have the same construction as the object microphone  114  and speech-judgment unit  115  of the first embodiment.  
      Also, the data-memory unit  111  of this embodiment forms the memory means of the invention, and the data-sending/receiving unit  112  forms the transmission means of the invention. Moreover, the instrument microphone  211  of this embodiment, for example, forms the sound-source microphone of this invention, and the output-judgment unit  212  forms the judgment means of the invention.  
      Similar to as in the first embodiment, the transmission-apparatus-control unit of this embodiment mainly comprises a central processing unit (CPU) and a memory, and when sending or receiving data, it performs overall control of general functions.  
      Particularly, in this embodiment, based on the judgment result from the output-judgment unit  212  and the attribute data stored in the data-memory unit  111 , the data-transmission apparatus  210  control unit generates object data  42  and outputs that generated object data  42  to the data-recording apparatus  220  by way of the data-sending/receiving unit  112 .  
      More specifically, based on the judgment results input from the output-judgment unit  212 , the data-transmission-apparatus  210  control unit generates instrument information that indicates whether or not there is rumbling or sound output from the instrument.  
      The data-transmission-apparatus  210  control unit generates object data  22  based on attribute data comprising instrument information that is generated as described above, performer ID, performer-name information, age information and instrument name information, and outputs the generated object data  22  to the data-recording apparatus  220 .  
      On the other hand, in order to conform with the first embodiment, the data-transmission apparatus  210  control unit, based on an instruction from the data-recording apparatus  220 , sends specified data to the data-sending/receiving unit  112  for verifying that the data-transmission apparatus  210  is an apparatus capable of accessing the data-recording apparatus  220 .  
      Next,  FIG. 11  will be used to explain the construction of the data-recording apparatus of this embodiment.  FIG. 11  is a block diagram showing the construction of the data-recording apparatus of this embodiment.  
      As shown in  FIG. 10 , the data-recording apparatus  220  of this embodiment comprises: a operation unit  124 ; a pick-up microphone  126  that picks up sound from an instrument; an audio-data-conversion unit  127  that converts the audio signal acquired by the pick-up microphone  126  to audio data having a specified format; a data-transmission unit  128  that is connected to an antenna AT and that receives the object data  42  that contains attribute data and that was sent from the data-transmission apparatus  210 , as well as sends or receives various data related to that object data  42 ; a data-generation unit  129  that generates an audio stream  3  based on the audio data and object data  42 ; a data-recording unit  130  that records the generated audio stream  3 ; a system-control unit  131  that controls each part, and ROM/RAM  132 .  
      The audio-data-conversion unit  127  of this invention, for example, forms the acquisition means and data-acquisition means of this invention, and the pick-up microphone  126  forms the forms the pick-up microphone of the invention. Moreover, the data-communication unit  128 , for example, forms the receiving means of this invention, and the data-recording unit  130  of this embodiment forms the recording means of this invention.  
      The audio data and object data  42  are input to the data-generation unit  129  of this embodiment, and based on the input audio data and object data  42 , this data-generation unit  129  generates an audio stream  3  having a specified format, and outputs the generated audio streams  3  in order to the data-recording unit  130 .  
      More specifically, this data-generation unit  129  generates the frame-group data  30  that contains the object data for each frame, and generates an audio stream  3  containing a plurality of this generated frame-group data  30 .  
      For example, as described above, the data-generation unit  129  of this embodiment generates frame-group data  30  for each frame group of about 1 to 15 frames that comprises a header section  31 , a contents-data section  32  that contains audio data for each frame, and a meta-data section  33  that contains object data  42 .  
      Next,  FIG. 12  will be used to explain the control by the system-control unit in the recording process by the data-recording apparatus of this embodiment, and the operation by each part.  
       FIG. 12  is a flowchart that shows the control by the system-control unit in the recording process by the data-recording apparatus of this embodiment, and the operation by each part.  
      Also, it is presumed that all of the attribute data is already stored in the data-transmission apparatus  210 , that the data-transmission apparatus  210  has already been verified by the verification process described above, and that it sends object data  22  to the data-recording apparatus  220 .  
      First, when the user controls the control unit  24  and sends an instruction to the system-control unit  131  to start recording audio data, the system-control unit  131  determines whether or not the amount of time for one frame has elapsed based on the internally generated reference clock (step S 41 ), and when it determines that the amount of time of one frame has not yet elapsed, it repeats this process, and when it determines that the amount of time of one frame has elapsed, it executes the following process for each frame.  
      Next, when the system-control unit  131  determines that the amount of time of one frame has elapsed based on the reference clock, it has the audio-data-conversion unit  127  execute the audio-data process for the audio signal output from the pick-up microphone  126 , and output the processed audio data to the data-generation unit  129  (steps S 42  and S 43 ).  
      More specifically, the audio-data-conversion unit  127  samples the input audio signal using a specified period, and converts it to a digital signal (step S 42 ), and then encodes the converted digital signal into a specified format and outputs it to the data-generation unit  129  (step S 43 ).  
      On the other hand, the system-control unit  131  has the data-communication unit  128  receive each object data  42  (step S 44 ) and determine whether or not each object data  42  contains a performer ID that is different than the performer ID that was registered for the previous frame (step S 45 ), and when there is object data having a performer ID that is different than the performer ID that was registered for the previous frame, output that object data  42  to the data-generation unit  129  (step S 46 ).  
      At this time, when it is determined by the data-communication unit  128  that there is no performer ID in some object data that is different than the performer ID that was registered for the previous frame, the data-communication unit  128  does not output that object data  42  to the data-generation unit  129 . Also, the system-control unit  131  performs the audio-data process and judgment process at the same time.  
      Next, as described above, the system control unit  131  has the data-generation unit  129  generate contents data based on the audio data for each frame, and then determine based on the frames of the generated contents data whether or not the specified number of frames of the frame group to which the frame belongs to has been reached (step S 47 ).  
      At this time, when the system-control unit  131  determines based on the frame of the contents data generated by the data-generation unit  129  that the specified number of frames for the frame group has not been reached, then the system-control unit  131  goes to the process of step S 41  and has the data-generation unit  129  generate the next frame of contents data.  
      On the other hand, when the system-control unit  131  determines based on the frame of contents data generated by the data-generation unit  129  that the specified number of frames for the frame group has been reached, then as described above, the system-control unit  131  has the data-generation unit  129  generate a header section using data other than the object data  42 , and then generate frame-group data  10  based on the contents data for each frame, the object data  42  and that header (step S 48 ).  
      As in the first embodiment, when there is no performer ID in any of the object data  42  that is different than the performer ID that was registered for the previous frame-group data  10 , and that object data  42  is not input to the data-generation unit  129 , the data-generation unit  129  generates object data  42  for that frame based on the object data of the previous frame.  
      Next, the system-control unit  131  has the frame-group data  30  generated by the data-generation unit  129  output to the data-recording unit  130  and records that frame-group data  30  in the data-recording unit  130  (step S 49 ).  
      Finally, the system-control unit  131  determines based on other control by the operation unit  124  whether or not data recording has ended (step S 50 ), and when it determines that data recording is continuing, it goes to the process of step S 41 , and when it determines that data recording has ended, it ends this operation.  
      The data-recording system  200  of this embodiment described above is a data-recording system  200  that records sound generated from a sound source as contents data, and is constructed such that it comprises: a data-transmission apparatus  210  that is attached to the sound source and sends object data  42  that indicates the attributes of the sound source; and a data-recording apparatus  220  that correlates and records the object data  42  sent from the data-transmission apparatus  210  with the sound generated from the sound source to which that data-transmission apparatus  210  is attached.  
      The data-recording system  200  of this embodiment having this construction correlates and records the object data  42  sent from the data-transmission apparatus  210  attached to the sound source with the sound generated from the sound source.  
      Therefore, when recording the sound source, it is possible to correlate and record the object data  42  of the source with the sound source, so when editing the recorded sound source, such as when analyzing music such as recorded songs, or when accurately reproducing just the sound of an instrument in music such as a recorded song, it is possible to perform recording and reproduction based on that object data  42 .  
      Moreover, the data-recording system  200  of this embodiment is constructed such that the data-recording apparatus  220  comprises: a pick-up microphone  126  that picks up sound generated from a sound source; an audio-data-conversion unit  127  that acquires the sound picked up by the microphone as contents data; a data-communication unit  128  that receives object data  42  sent from the data-transmission apparatus  210 ; and a data-recording unit  130  that records the acquired audio data and correlates the received object data  42  with the audio data to be recorded and records them.  
      The data-recording system  200  of this embodiment having this construction acquires sound generated from a sound source as contents data, and receives object data  42  sent from the data-transmission apparatus  210 , and when recording the acquired audio data, correlates the received object data  42  with the audio data to be recorded and records them.  
      Therefore, when recording sound generated from a sound source, it is possible to correlate and record it with sound generated from a sound source such as music, so when editing the recorded sound source, such as analyzing music such as recorded songs, or when accurately reproducing just the sound of an instrument in music such as a recorded song, it is possible to perform recording and reproduction based on that object data  42 .  
      Also, the data-recording apparatus  220  of this embodiment is constructed such that when the audio-conversion unit  127  acquires picked up sound as audio data containing a plurality of frames, the data-recording unit  130  correlates and correlates the object data  42  with the audio data to be recorded for each frame and records them.  
      With the data-recording apparatus  220  of this embodiment having this construction, object data  42  is correlated with the audio data for each frame and recorded, so when editing the recorded sound source, or when performing reproduction, it is possible to perform recording and reproduction based on that object data  42  for each frame.  
      Also, the data-recording apparatus  220  of this embodiment is constructed such that the data-communication unit  128  receives ID information for identifying the sound source from which sound is acquired from other sound sources, name information that indicates the name of the sound source, or operator information related to the operator, who operates the sound source in order to output sound from the sound source, as attribute information.  
      In this embodiment having this construction, attribute information such as ID information can be recorded in the data-recording unit  130  together with audio data, so when editing the recorded sound source, such as when analyzing music such as recorded songs, or when accurately reproducing just the sound of an instrument in music such as a recorded song, it is possible to perform recording and reproduction based on that object data  42 .  
      Also, when the audio-data-conversion unit  127  acquires sound generated from a sound source as contents data, the data-recording apparatus  220  of this embodiment has a pick-up microphone  126  that picks up sound generated from the sound source, and acquires the sound picked up by the microphone as contents data.  
      The data-recording apparatus  220  of this embodiment having this construction acquires sound generated from a sound source as contents data, as well as receives object data  42  sent from a data-transmission apparatus  210 , and when recording the acquired audio data, correlates the received object data with the audio data to be recorded and records them.  
      Therefore, when recording sound generated from a sound source, it is possible to correlate and record it with sound such as music generated from a sound source, so when editing the recorded sound source, such as when analyzing music such as recorded songs, or when accurately reproducing just the sound of an instrument in music such as a recorded song, it is possible to perform recording and reproduction based on that object data  42 .  
      Furthermore, the data-recording apparatus  220  of this embodiment is constructed such that the data-communication unit  128  receives rumbling information together with the attribute information, and records that rumbling information in the data-recording unit  130  together with the attribute information.  
      In this embodiment having this construction, this rumbling information is recorded in the data-recording unit  130  together with the audio data, so when editing the recorded sound source, such as when analyzing music such as recorded songs, or when accurately reproducing just the sound of an instrument in music such as a recorded song, it is possible to perform recording and reproduction based on that object data  42 .  
      Also, the data-recording apparatus  220  of this embodiment is constructed such that when the data-communication unit  128  sends or receives contents data to or from the data-transmission apparatus  210 , it determines whether or not the data-transmission apparatus is able to send or receive that contents data.  
      With the data-recording apparatus  220  of this embodiment having this construction, whether or not the  15  data-transmission apparatus  210  is able to send or receive contents data is determined when sending or receiving contents data to or from the data-transmission apparatus  210 , so it is possible to prevent object data  42  sent from the data-transmission apparatus from unintentionally flowing to the outside.  
      The data-transmission apparatus  210  of this embodiment is constructed such that it comprises: an instrument microphone that picks up sound generated from a sound source  211 , and an output-judgment unit  212  that, based on the sound picked up using the instrument microphone, determines whether or not there is sound output from the sound source, and the data-sending/receiving unit  112  sends speech information that indicates the judgment result determined by the output-judgment unit  212 .  
      With the data-transmission apparatus  210  of this embodiment constructed as described above, speech information that indicates the judgment result determined by the speech-judgment unit can be sent to the data-recording apparatus  220 , so by recording this speech information in the data-recording unit  130  together with audio data or video data when editing the recorded sound source, such as when analyzing music such as recorded songs, or when accurately reproducing just the sound of an instrument in music such as a recorded song, it is possible to perform recording and reproduction based on that object data  42 .  
      This embodiment is used when recording a song that is performed at a concert or in a studio for example, however, of course it is not limited to a song that is performed at a concert or in a studio, and could also be used for conversation, a singing contest, or as a consumer device. In this case, characteristic information such as the age and name of the object being recorded is stored in the object data  42 .  
      Moreover, in this embodiment, object data  42  is recorded in the data-transmission apparatus  210  using a communication terminal from the outside, however, it is also possible to have a control-input unit in the data-transmission apparatus  210  that comprises a plurality of keys such as confirmation buttons, selection buttons, number keys and the like, and record object data  42  in the data-memory unit  111  by controlling this control-input unit.  
      In this case, there is also a display unit used for displaying the control input of the control-input unit in order to assist in the control input, and for checking the attribute information to be stored.  
      Also, in this embodiment, the system-control unit  131  executes control of each unit in the verification process, and controls of each unit in the recording process by the system-control unit  131 , however, by having a recording medium on which a program is recorded that regulates the operation of the recording process, and a computer that can read it, it is possible to perform the operation of the same recording process described above by having the computer read this program.
