Description

  The present invention relates to a recorder that includes a memory and records data by writing data until the storage capacity of the memory is reached.

2. Description of the Related Art In recent years, recording machines that include a memory and perform recording by storing sound data representing a waveform of a sound to be recorded until the storage capacity of the memory is reached have been widely used (for example, Patent Document 1).
JP 2002-118662 A

However, since the technique disclosed in Patent Document 1 cannot perform recording of a data amount exceeding the storage capacity of a memory provided in the recording device, when performing high-quality recording, the unit per unit time There is a problem that the recording time is shortened because the amount of audio data increases compared to the case of recording with low quality. In addition, when recording for a long time, there is a problem that the amount of audio data per unit time must be reduced and the recording quality must be lowered. That is, the technique disclosed in Patent Document 1 has a problem in that the recording quality and the recording time are in a trade-off relationship, and both cannot be made compatible. Such problems can be solved by increasing the storage capacity of the memory provided in the recorder (for example, replacing the memory provided in the recorder with a larger memory). However, it is difficult to mount a large-capacity memory in a portable recording device due to the limited memory installation space. Also, increasing the storage capacity of the memory increases the product cost of the recorder, which is not preferable from this point.
An object of the present invention is to provide a technique that enables high-quality recording for a long time without increasing the storage capacity of a memory provided in a recording device.

  In order to solve the above-described problems, the present invention provides a recording apparatus that includes a memory and records the data by writing the data to the memory until the storage capacity of the memory is reached. Dividing and writing to the memory in units of the data blocks, while transmitting the data blocks to a predetermined destination via a communication network, and to each of the data blocks transmitted by the transmitting means to the predetermined destination A recording apparatus comprising: confirmation means for confirming whether or not the data has been reached; and erasing means for erasing the data block confirmed by the confirmation means to reach the predetermined destination from the memory. provide.

In order to solve the above-mentioned problem, the present invention provides a recording apparatus that includes a memory and performs recording by writing sound data representing a waveform of a sound to be recorded into the memory until reaching the storage capacity of the memory. The audio data is divided into data blocks of a predetermined size and written to the memory in units of the data blocks, while the data blocks are transmitted to a predetermined destination via a communication network, and transmitted by the transmission means Confirmation means for confirming whether or not the predetermined destination has been reached for each of the data blocks; erasure means for erasing the data block confirmed by the confirmation means to reach the predetermined destination; The recording device is characterized by comprising:
According to such a recorder, the voice data representing the voice to be recorded is divided into data blocks of a predetermined size and stored in the memory in units of the data block until the storage capacity of the memory provided in the recorder is reached. On the other hand, the data block is transmitted to a predetermined destination via the communication network, and the data block whose arrival at the destination is confirmed is deleted from the memory. Therefore, if the destination is a communication device that stores data blocks sequentially transmitted from the recorder and has a function of restoring the audio data by connecting the data blocks, the audio to be recorded Even when the data size of the audio data representing is larger than the storage capacity of the memory, each of the data blocks corresponding to the audio data is stored in either the recorder or the communication device (ie, , The voice represented by the voice data is recorded).

  In a more preferred aspect, the apparatus further comprises a re-transmission unit that re-transmits the data block that has been confirmed by the confirmation unit to have not reached the predetermined destination by the transmission unit at a predetermined timing. According to such an aspect, the data block that has been confirmed by the confirmation unit and has not reached the predetermined destination is retransmitted to the predetermined destination by the retransmission unit, If the retransmission is successful (that is, when the confirmation means confirms that the retransmitted data block has reached the predetermined destination), the data block is deleted from the memory.

  In another preferred embodiment, the data block confirmed by the confirmation means that the predetermined destination is not reached is written to a computer-readable recording medium, and the data block is written by the erasure means. It has a recording medium writing means for erasing from the memory. According to such an aspect, the data block that has been confirmed by the confirmation means to have not reached the predetermined destination and remains in the memory is, for example, a CD-ROM (Compact Disk-Read Only Memory). It becomes possible to input to the predetermined destination via a computer-readable recording medium.

  In another preferred aspect, the generating means for generating the second sound data representing the sound to be recorded, the sound data having lower sound quality than the sound data, and the recording It has a reproduction means for reproducing sound according to the second sound data when an instruction to reproduce the target sound is given. In such an aspect, immediately after the recording of the sound to be recorded is completed, the recording result can be roughly confirmed using the recording device.

  Moreover, in another preferable aspect, the second sound data representing the sound to be recorded, the second sound data representing sound having a lower sound quality than the sound data, and generating means for generating, When the data amount of the data block stored in the memory reaches a predetermined threshold value that is equal to or less than the storage capacity of the memory, the transmission means replaces the audio data with the second audio data. The data block is divided into the predetermined size, the data block is written to the memory, and the data block is transmitted to the predetermined destination via the communication network. According to such an aspect, after the amount of data stored in the memory reaches the threshold value, the sound quality is reduced (that is, the amount of data per unit time is reduced) and recording can be continued. It becomes possible, and it becomes possible to record for a longer time.

Further, in order to solve the above-mentioned problems, the present invention records a sound by causing the computer device to store sound data representing a waveform of the sound to be recorded in the memory until the memory capacity of the computer device is reached. In the program to be transmitted, the computer device divides the audio data into data blocks of a predetermined size and writes the data blocks to the memory in units of data blocks, while transmitting the data blocks to a predetermined destination via a communication network Means for confirming whether or not each of the data blocks transmitted by the transmitting means has reached the predetermined destination, and a data block for which the confirmation means has confirmed that the predetermined destination has been reached Functioning as erasing means for erasing from the memory Lamb, to provide. According to such a program, it is possible to provide a general computer apparatus with the same function as that of the recorder according to the present invention.

The best mode for carrying out the present invention will be described below with reference to the drawings.
(A. Configuration)
(A-1: Configuration of the communication system 10)
FIG. 1 is a diagram illustrating a configuration example of a communication system 10 including a recording device 100 according to an embodiment of the present invention. As shown in FIG. 1, the communication system 10 includes a communication network 200, a recorder 100 connected to the communication network 200, and a voice data storage server 300 that is also connected to the communication network 200. include. In the communication system 10 illustrated in FIG. 1, the case where one recorder is connected to the communication network 200 is illustrated, but it is needless to say that a plurality of recorders may be connected to the communication network 200. It is. Similarly, in the communication system 10 shown in FIG. 1, the case where one voice data storage server is connected to the communication network 200 is illustrated, but a plurality of voice data storage servers are connected to the communication network 200. Is of course good.

  The recorder 100 includes a memory for storing data in a nonvolatile manner, and records the sound by storing the sound data representing the waveform of the sound to be recorded in the memory. As will be described in detail later, the recorder 100 divides the audio data into data blocks of a predetermined data size (for example, 128 bytes or 256 bytes) when writing the audio data into the memory, and A unique identifier (in this embodiment, a sequence number indicating the number of the data block from the beginning) is assigned and written to the memory, and the data block with the identifier is communicated according to a predetermined communication protocol. It is configured to transmit to a predetermined destination (in this embodiment, the voice data storage server 300) via the network 200. In the present embodiment, the case where the identifier assigned to each data block is the sequence number will be described. However, the number of bits in the audio data is the first bit of the data block. Of course, the data shown may be used as the identifier.

  The communication network 200 is, for example, the Internet, and has a function of mediating communication performed between the recorder 100 and the voice data storage server 300 in accordance with the predetermined communication protocol. In the present embodiment, a case where the communication network 200 is the Internet will be described, but it is needless to say that it may be a LAN (Local Area Network). The point is that the recording network 100 and the audio data storage server 300 may be connected to each other by wire, and any communication network having a function of mediating data communication performed in accordance with a predetermined communication protocol between them may be used. In this embodiment, the case where the recording device 100 and the audio data storage server 300 are connected to the communication network 200 by wire is described. However, the communication network 200 is, for example, a mobile packet communication network or a wireless LAN. Of course, it may be a wireless communication network that accommodates the recorder 100 and the voice data storage server 300 and mediates communication performed between them according to a predetermined communication protocol.

  The voice data storage server 300, when receiving a data block transmitted via the communication network 200, similarly to a general communication device that communicates according to TCP, for example, indicates that the data block has been received. A message (hereinafter referred to as an acknowledgment message) is returned to notify the transmission source that the data block has been received. More specifically, the audio data storage server 300 writes the sequence number given to the received data block in the confirmation response message and sends it back to indicate that the data block has been received. Notify the original. The voice data storage server 300 stores the received data blocks, and when all the data blocks corresponding to the voice data representing the voice to be recorded are collected, the data blocks are connected in the order of their sequence numbers. It also has a function to restore the audio data. The voice data storage server 300 only notifies the sender that the data block has been received by sending back an acknowledgment message in which the sequence number assigned to the received data block is written. Therefore, since it differs from the general communication apparatus which communicates, this is abbreviate | omitted about the detailed description of the structure and operation | movement. In this embodiment, by sending back an acknowledgment message in which the sequence number assigned to the received data block is written back to the sender of the data block, the sender is notified that the data block has been correctly received. In the same way as a general communication device that operates in accordance with TCP, the sequence number assigned to the data block subsequent to the received data block (for example, the sequence number assigned to the received data block) If “1” is “1”, it is of course possible to notify that the data block has been correctly received by returning an acknowledgment message in which “2”) is written to the transmission source of the data block. .

  In the communication system 10 shown in FIG. 1, when the recording response is returned from the voice data storage server 300, the recorder 100 recognizes the data identified by the sequence number written in the confirmation response message. The block is erased from its own memory. That is, in the communication system 10 shown in FIG. 1, each data block corresponding to the sound data representing the waveform of the sound to be recorded is transmitted from the recorder 100 to the sound data storage server 300, and these data blocks are transmitted to the sound data. By storing the data in the storage server 300, voice recording is performed. Since the data block confirmed to reach the voice data storage server 300 is deleted from the memory of the recorder 100, the data size of the voice data representing the waveform of the voice to be recorded is the recorder 100. Even if it is larger than the storage capacity of the memory provided in, the voice represented by the voice data can be recorded. That is, high-quality sound recording can be performed for a long time without increasing the storage capacity of the memory provided in the recorder 100. Hereinafter, the configuration and operation of the recorder 100 will be mainly described.

(A-2: Configuration of the recorder 100)
FIG. 2 is a block diagram illustrating an example of a hardware configuration of the recording device 100.
As shown in FIG. 2, the recorder 100 includes a storage unit 110, an audio processing unit 120, a control unit 130, a communication interface (hereinafter “IF”) unit 140, and a bus that mediates data exchange between these units. 150.

  As shown in FIG. 2, the storage unit 110 includes a nonvolatile memory 110a and a volatile memory 110b. The non-volatile memory 110a is, for example, an EEPROM (Electronically Erasable and Programmable Read Only Memory), and a control program for causing the control unit 130 to execute processing characteristic of the recorder according to the present invention and the transmission destination of the data block described above. A communication address (in this embodiment, an IP address assigned to the voice data storage server 300: hereinafter referred to as “destination address”) is written in advance. The non-volatile memory 110a is also used as a memory for storing sound data representing sound to be recorded. On the other hand, the volatile memory 110b is, for example, a RAM (Random Access Memory), and is used as a work area by the control unit 130 operating according to the control program. In the present embodiment, the case where the nonvolatile memory 110a has the function of storing the control program and the function of storing audio data has been described. However, the storage location of the control program and the storage location of the audio data are described. Of course, each may be a separate nonvolatile memory. Further, in the present embodiment, it is needless to say that the nonvolatile memory 110a may be configured by an HDD (Hard Disk Drive) described in the case where the nonvolatile memory 110a is configured by an EEPROM.

  The sound processing unit 120 is connected to a microphone 120a that collects sound to be recorded and outputs a sound signal corresponding to the sound. The audio processing unit 120 includes an A / D conversion circuit (not shown) that performs A / D conversion on the audio signal to generate audio data that is a digital audio signal, and the audio data is transmitted via the bus 150. To the control unit 130. In the present embodiment, the case where the microphone 120a is included in the recorder 100 has been described. However, even if an input terminal is provided to the audio processing unit 120 and an external microphone is connected to the input terminal via an audio cable. good. In the present embodiment, the case where the audio signal input from the microphone 120a to the audio processing unit 120 is an analog audio signal has been described. However, it is of course possible to input a digital audio signal. In such a case, it goes without saying that the audio processing unit 120 does not need to perform A / D conversion.

  The control unit 130 is, for example, a CPU (Central Processing Unit), and when the recording device 100 is powered on (not shown), the control program is read from the nonvolatile memory 110a and executed, and the control program is executed according to the control program. The processing characteristic of the recorder according to the invention is executed. More specifically, the control unit 130 operating in accordance with this control program divides the audio data delivered from the audio processing unit 120 into a predetermined data size to generate the above-described data block, and the non-volatile memory 110a. These data blocks are written to the nonvolatile memory 110a until the storage capacity reaches the predetermined storage capacity, while the communication IF unit 140 writes the data blocks to a predetermined destination identified by the transmission destination address (the voice data storage server 300 in this embodiment). Execute the process to send to. In addition, when the control unit 130 operating according to the control program receives the above-described confirmation response message by the communication IF unit 140, the data block identified by the sequence number written in the confirmation response message Is deleted from the nonvolatile memory 110a. In the present embodiment, the case where the control unit 130 starts executing the control program when the recording device 100 is turned on has been described. However, when the power is turned on, First, it is of course possible to cause the control unit 130 to start executing an OS (Operating System) and cause the control unit 130 to execute the control program under the control of the OS.

  The communication IF unit 140 is, for example, a NIC (Network Interface Card), and is wired to the communication network 200. The communication IF unit 140 receives data (for example, the above-described confirmation response message) sent from the communication network 200 and delivers it to the control unit 130, while the data delivered from the control unit 130 (for example, the transmission destination address). The data block transmitted to the destination identified by (1) is transmitted to the communication network 200.

  The above is the hardware configuration of the recorder 100 according to the present embodiment. Thus, the hardware configuration of the recorder 100 according to the present embodiment is the same as the hardware configuration of a general computer apparatus except that the audio processing unit 120 and the communication IF unit 140 are provided. The characteristic functions of the recorder 100 according to the above are realized by operating the control unit 130 according to the control software (that is, with a software module).

(B. Operation)
Next, voice recording processing performed by the control unit 130 of the recording device 100 according to the control program described above will be described with reference to the drawings. In the operation example described below, it is assumed that the power of the recorder 100 has been turned on, and the control unit 130 of the recorder 100 is operating according to the control software. In addition, it is assumed that none of the above-described data blocks is stored in the nonvolatile memory 110a before the start of the operation example described below.

  When the control unit 130 operates in accordance with the control software and the user operates the operation unit (not shown) of the recorder 100 to instruct the start of recording, the sound to be recorded is collected by the microphone 120a. The voice data representing the voice is delivered from the voice processing unit 120 to the control unit 130. In this way, the control unit 130 to which the audio data has been delivered executes the recording process shown in FIG. 3 in accordance with the control program described above.

  As shown in FIG. 3, the control unit 130 first determines whether the data amount of the data block stored in the nonvolatile memory 110a has reached the storage capacity of the nonvolatile memory 110a (step SA100). ), When the determination result is “Yes”, the recording process is terminated. On the other hand, when the determination result in step SA100 is “No”, the control unit 130 executes the processes after step SA110 shown in FIG. As described above, since none of the data blocks described above is stored in the nonvolatile memory 110a before the start of this operation example, immediately after the start of this operation example, the determination result in step SA100 is “ No "and processing after step SA110 is executed.

  In step SA110, which is subsequently executed when the determination result in step SA100 is “No”, the control unit 130 divides the audio data delivered from the audio processing unit 120 into data blocks of a predetermined size, and A unique sequence number is assigned to each and written and stored in the nonvolatile memory 110a.

  Next, the control unit 130 reads the data blocks stored in the nonvolatile memory 110a in step SA110 to the volatile memory 110b in ascending order of the sequence numbers (creates a copy of the data block in the volatile memory 110b). Then, a header in which the above-mentioned destination address is written is added to the read data block, delivered to the communication IF unit 140, and sent to the communication network 200 (step SA120). The data block transmitted from the recorder 100 in this way basically reaches the voice data storage server 300 via the communication network 200 and is stored in the voice data storage server 300. Depending on the usage status of the communication network 200, the voice data storage server 300 may not be reached. As described above, when the voice data storage server 300 receives a data block transmitted via the communication network 200, the voice data storage server 300 transmits an acknowledgment message in which the sequence number assigned to the data block is written. Since the response is returned to the original, the control unit 130 determines whether or not the data block transmitted in step SA120 has reached its destination by determining whether or not the confirmation response message has been returned. can do.

  In step SA130 executed after step SA120, control unit 130 determines whether or not each data block transmitted in step SA120 has reached its destination. For the data block whose determination result in step SA130 is “Yes” (that is, the data block confirmed to reach the audio data storage server 300), the control unit 130 removes the data block from the nonvolatile memory 110a. Erasing (step SA140), conversely, for the data block whose determination result in step SA130 is “No”, the data block is retransmitted when a predetermined time has elapsed from the time when the data block was transmitted (step SA150). The processes after SA100 are repeatedly executed. As a result, the control unit 130 cannot confirm the arrival at the audio data storage server 300, so that the data amount of the data block that has not been erased from the nonvolatile memory 110a reaches the storage capacity of the nonvolatile memory 110a. Recording will continue. In the present embodiment, the case where data blocks that have not been confirmed to arrive at the voice data storage server 300 are retransmitted when a predetermined time has elapsed from the time of transmission has been described. Of course, all the data blocks stored in the non-volatile memory 110a may be retransmitted when the instruction is issued. In addition, the degree of load applied to the communication network 200 is detected by, for example, ping, and the data block is retransmitted when the detection result (that is, the degree of load) is equal to or less than a predetermined threshold. Also good. In short, any mode may be used as long as the data block is retransmitted at a predetermined timing.

  As a result of the operations described above being performed, according to the present embodiment, each data block corresponding to audio data representing the waveform of the audio to be recorded is transmitted from the recorder 100 to the audio data storage server 300, and Recording is performed by storing the data block in the voice data storage server 300, and the data block confirmed to reach the voice data storage server is deleted from the memory of the recorder 100. Therefore, in the communication system 10, it is possible to record a voice represented by voice data having a data size larger than the storage capacity of the memory provided in the recorder 100, and provided in the recorder 100. There is an effect that high-quality sound recording can be performed for a long time without increasing the storage capacity of the existing memory.

  In addition, according to the present embodiment, the following effects can be obtained as compared with the case where the data block is transmitted from the recording device to the audio data storage server using an existing communication protocol such as TCP or UDP. That is, when TCP is used for the transfer of the data block, basically, it is confirmed by the ACK returned from the destination that the transmitted data block has reached the destination, and then the subsequent data Block transmission is performed, thereby ensuring the reliability of data communication. On the other hand, in the present embodiment, since the data block subsequent to the data block is transmitted without waiting for the reception of the confirmation response message for the preceding data block, the data is compared with the case where TCP is used. It becomes possible to improve the transfer efficiency. In addition, when UDP is used to transfer the data block, it is possible to perform high-speed data communication because it does not check whether the transmitted data block has reached its destination. It becomes impossible to ensure reliability. On the other hand, according to the present embodiment, since it is possible to confirm that the transmitted data block has reached its destination depending on whether or not an acknowledgment message has been received, it is more reliable than UDP. High data communication can be performed.

(C. deformation)
Although one embodiment of the present invention has been described above, it goes without saying that the following modifications may be added to the above-described embodiment.
(1) In the above-described embodiment, the case where the data block that has not been erased from the nonvolatile memory 110a because the arrival at the voice data storage server 300 has not been confirmed has been retransmitted at a predetermined timing has been described. However, the data block as described above may be written to a computer-readable recording medium such as a CD-ROM and input to the audio data storage server 300 using the recording medium. This is because the recording medium writing means for erasing the data block from the nonvolatile memory 110a while writing the data block that has been confirmed not to reach the audio data storage server 300 to the recording medium 100 is provided. Should be provided.

(2) In the embodiment described above, the audio data representing the audio to be recorded is divided into data blocks of a predetermined size, and these data blocks are transmitted to the audio data storage server 300 via the communication network 200 and stored. The case where only the data block whose arrival at the voice data storage server 300 has not been confirmed is left in the nonvolatile memory 110a of the recorder 100 has been described. However, in such an aspect, since the entire audio data representing the audio to be recorded is not stored in the recorder 100, the recorded audio is played back and the recording result is confirmed after the recording is completed. It can happen that you can't.

  Therefore, in order to solve such a problem, the second audio data representing the sound to be recorded is more than the sound represented by the audio data divided into a plurality of data blocks and transferred to the audio data storage server 300. Generating means for generating second sound data representing sound with low sound quality (for example, sound data generated by A / D conversion sampled at a wider sampling interval than the transferred sound data), and sound to be recorded Reproduction means for reproducing sound according to the second sound data (for example, a D / A converter that performs D / A conversion on the second sound data, and the D / A The recording device 100 may be provided with a speaker that outputs sound in accordance with the sound signal converted by the converter. In this way, it becomes possible to reproduce the sound according to the second sound data, and roughly check the recording result after the recording is completed (the second sound data is divided into the plurality of data blocks. In order to represent lower quality speech).

(3) In the above-described embodiment, the case where recording is continued until the data amount of the data block stored in the nonvolatile memory 110a reaches the storage capacity of the nonvolatile memory 110a has been described. However, after the data amount of the data block stored in the non-volatile memory 110a reaches a predetermined threshold value smaller than the storage capacity, the sound to be recorded is converted into sound data with lower sound quality and stored. Of course it is good. Specifically, the second voice data representing the voice to be recorded represents voice having lower sound quality than the voice represented by the voice data divided into a plurality of data blocks and transferred to the voice data storage server 300. The recording device 100 is provided with generating means for generating second audio data, and when the data amount of the data block stored in the nonvolatile memory 110a reaches the threshold value, the second audio data is converted to the second audio data. It is only necessary to divide the data block into a predetermined size, write the data block to the nonvolatile memory 110a, and transmit the data block to a predetermined destination via the communication network 200. In this way, after the data amount of the data block stored in the non-volatile memory 110a reaches the threshold value, the sound data whose sound quality has been reduced (that is, the sound data whose data amount per unit time has decreased). By storing, there is an effect that it is possible to extend the recordable time.

(4) In the above-described embodiment, the present invention is applied to a recorder that records sound by writing sound data representing sound to be recorded into the nonvolatile memory until the storage capacity of the nonvolatile memory is reached. In the above, the case where recording is performed exceeding the storage capacity of the nonvolatile memory has been described. However, the scope of application of the present invention is not limited to a recorder, but to a recorder (for example, a hard disk recorder or a digital camera) that performs recording by storing moving image data or still image data in a memory, or to a memory. The present invention can also be applied to a document recorder that stores text data and records a document represented by the text data. In short, the present invention can be applied to any recording device that includes a memory and records the data by writing the data in the memory. Specifically, in such a recorder, data is divided into data blocks of a predetermined size and written to the memory of the recorder in units of the data blocks, while the data blocks are sent to a predetermined destination via a communication network. Transmitting means for transmitting, confirmation means for confirming whether or not each of the data blocks transmitted by the transmitting means has reached the predetermined destination, and data for which the confirmation means has confirmed that the predetermined destination has been reached By providing an erasing unit for erasing the block from the memory, data can be recorded more than the storage capacity of the memory. In addition, when the present invention is applied to a recorder that records moving images and still images, the image quality is lower than the image data transferred to a predetermined destination, as in the case of the modification (2) described above. By generating the second image data representing an image (for example, a low resolution image), it is possible to roughly check the recording result after the recording is completed. In addition, when the present invention is applied to a document recorder, in addition to text data that is divided into data blocks of a predetermined size and transferred to a predetermined destination, a second text that represents a summary of the document represented by the text data By generating the data, it is possible to roughly check the recording result after the recording is completed, as in the case of the modified example (2) described above.
