Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recording apparatus, a reproducing apparatus, and a recording / reproducing apparatus for recording or reproducing an input signal as digital data, and to divide digital data at an arbitrary timing according to the timing, and obtain a file obtained therefrom. The present invention relates to a recording device, a reproducing device, and a recording / reproducing device for recording or reproducing as recording.
[0002]
[Prior art]
There are known a recording device for recording an input audio signal as digital data, a reproducing device for reproducing the recorded digital data, and a recording / reproducing device for recording / reproducing the audio signal as digital data.
In such a recording apparatus, a reproducing apparatus, and a recording / reproducing apparatus, for example, as in the case of using a voice recorder or the like, there is a demand for an operator to easily find a specific timing during reproduction.
A number of techniques relating to cueing of recorded digital data have been known in the past. For example, there is a technique described in Patent Document 1 below.
[0003]
[Patent Document 1]
JP-A-6-203538 (page 1, FIG. 1)
[0004]
[Problems to be solved by the invention]
Here, in the recording device, the reproducing device, and the recording / reproducing device disclosed in the patent document, in order to facilitate cueing at the time of reproduction, cueing at an arbitrary timing desired by an operator is performed. Mark information is added (index mark file method).
Then, in this case, an index file recording the mark information is separately created.
The index file includes a file number (file name) of digital data, position information of mark information included in the file (time information from a reproduction start position to mark information), and other attributes. .
[0005]
However, the method using the index mark file method has a problem that cueing using this mark information can be executed only between compatible models.
In addition, in the index mark file method, since a limit is imposed by setting mark information indicating a cue position, that is, the number of indices, there is a problem that a cue position exceeding the set number cannot be provided.
[0006]
On the other hand, to ensure that cueing can be performed even between incompatible models, temporarily stop recording at the position where cueing is to be performed during recording and manually divide the file. There is a known method (manual file division method).
By using such a method, the position to be searched becomes the head position of each file, so that there is an advantage that no compatibility problem occurs between any models.
[0007]
However, in such a manual file division method, a certain period of time is required for closing a file and opening a file, such as stopping recording of the immediately preceding file and starting recording of the corresponding file, at the cueing position. The problem that it becomes impossible to do so arises.
That is, when a continuous signal is input or the like, there is a problem that a missing portion occurs in recording.
Further, when a plurality of files are continuously reproduced, there is a problem that the reproduction is interrupted at the moment of moving to the next file.
[0008]
Therefore, the present invention has been made in view of the above circumstances, and it is possible to ensure compatibility between the respective models, perform continuous recording, and furthermore, perform recording at an arbitrary timing. It is an object of the present invention to realize a recording device that enables the recording to be performed.
Further, the present invention provides a reproducing apparatus which can ensure compatibility between models, can search for a file at an arbitrary timing, and can reproduce a plurality of files continuously. The purpose is to realize.
[0009]
In addition, according to the present invention, compatibility between the respective models can be ensured, and continuous recording can be performed. An object of the present invention is to realize a recording / reproducing device capable of continuously reproducing files.
[0010]
[Means for Solving the Problems]
The above-mentioned problem is solved by each of the solutions described below.
(1) An invention according to claim 1 is a recording apparatus for recording an input signal as digital data in a file format, comprising: a buffer memory for temporarily storing the input signal as digital data; Storage means for accumulating as a file, control means for performing control for accumulating digital data temporarily stored in the buffer memory as a file in the storage means, and division for dividing the digital data at an arbitrary timing. Operation input means for inputting, wherein the control means is configured to divide the digital data stored in the buffer memory, which is continuously input, according to the timing of the division operation from the operation input means. Write faster than input to the buffer memory to be a file Degrees performs control so as to accumulate in the storage means by, it is a recording apparatus according to claim.
[0011]
In the recording apparatus having such a configuration according to the present invention, the control for storing the continuously input digital data stored in the buffer memory in the storage unit at a higher writing speed than that input to the buffer memory is performed. While performing, control is performed such that the file is divided according to the timing of the division operation from the operation input unit.
[0012]
Therefore, control is performed to accumulate data in the storage unit at a writing speed higher than that input to the buffer memory, and the file is divided according to the timing of the division operation, so that a continuous signal is input. However, there is no missing portion in the record.
In other words, at the cue position, a certain time is required for closing and opening the file, such as stopping recording of the immediately preceding file and starting recording of the corresponding file. And the time required to write digital data can be shorter than the time required to input digital data, so that there is no problem with continuous recording.
[0013]
Further, in the recording apparatus having such a configuration, a file division method is employed instead of an index mark file method in order to search for desired digital data from among recorded digital data. Compatibility is ensured.
Also, for example, in the index mark file method, the number of cueing is consequently limited by the set number of indexes, and cueing cannot be performed beyond that number. However, in the file division method, the limit by the number of mark information is limited. Since there is no cue, it is possible to provide as many cue as necessary.
As a result, it is possible to realize a recording apparatus which can ensure the compatibility between the respective models, and can perform an arbitrary number of cueing at an arbitrary timing while performing continuous recording.
[0014]
(2) A reproducing apparatus for reproducing and outputting digital data in a file format recorded in a storage means, comprising: a storage means for storing digital data as a plurality of files; A buffer memory for temporarily storing the output digital data, and a buffer memory for temporarily storing a plurality of file format digital data stored in the storage means and outputting the digital data to the outside at a predetermined speed. Control means for performing control, wherein the control means externally outputs from the buffer memory so that digital data of a plurality of files stored in the storage means is output to the outside as continuous digital data. Digital data from the storage means to the buffer memory at a higher read speed than output. Performs control to read, it is a recording apparatus according to claim.
[0015]
In the reproducing apparatus having such a configuration of the present invention, control is performed to read digital data from the storage means to the buffer memory at a higher read speed than is output from the buffer memory to the outside, and a plurality of data stored in the storage means are controlled. The digital data of the file is output to the outside as continuous digital data.
[0016]
Therefore, since digital data is read from the storage means to the buffer memory at a higher read speed than is output from the buffer memory to the outside, even when a plurality of files are continuously played, the next file is read. Playback will not be interrupted at the moment of transition.
In other words, at the cueing position, a certain time is required for the process of closing and opening the file such as stopping the reproduction of the immediately preceding file and starting the reproduction of the corresponding file, but the time required for closing and opening the file and the reading time are Since the sum of the required time is shorter than the time required for outputting digital data, that is, the time required for reproduction output, there is no problem with continuous reproduction.
[0017]
Further, in the reproducing apparatus having such a configuration, a file division method is adopted instead of an index mark file method in order to search for desired digital data among recorded digital data. Compatibility is ensured.
Also, for example, in the index mark file method, the number of cueing is consequently limited by the set number of indexes, and cueing cannot be performed beyond that number. However, in the file division method, the limit by the number of mark information is limited. Since there is no cue, it is possible to provide as many cue as necessary.
As a result, it is possible to achieve compatibility between the respective models, to realize a playback apparatus capable of searching for an arbitrary number of files at an arbitrary timing and reproducing a plurality of files continuously. Become.
[0018]
(3) An invention according to claim 3 is a recording and reproducing apparatus for recording an input signal as digital data in a file format and reproducing and outputting the file format digital data recorded in the storage means. A plurality of files, a buffer memory for temporarily storing an input signal as digital data during recording, and temporarily storing digital data read from the storage means during reproduction. Operation input means for inputting division for dividing digital data at an arbitrary timing during recording, and control for storing digital data temporarily stored in the buffer memory as a file in the storage means at the time of recording. And data of a plurality of file formats stored in the storage means. Control means for temporarily controlling digital data to be temporarily stored in the buffer memory and outputting the digital data to the outside at a predetermined speed during reproduction, the control means comprising: Digital data to be input is stored in the storage unit at a higher writing speed than that input to the buffer memory so that the file is divided according to the timing of the division operation from the operation input unit. At the time of recording, so that the digital data of the plurality of files stored in the storage means is output to the outside as continuous digital data, so that the data is output at a higher speed than the output from the buffer memory to the outside. The digital data is read from the storage means to the buffer memory at a read speed. Performing control at the time of reproduction, it is a recording and reproducing apparatus according to claim.
[0019]
In the recording / reproducing apparatus having such a configuration of the present invention, the control for storing the continuously input digital data stored in the buffer memory in the storage unit at a higher writing speed than that input to the buffer memory is performed. While performing, control is performed such that the file is divided according to the timing of the division operation from the operation input unit.
[0020]
Further, in the recording / reproducing apparatus having such a configuration, control is performed to read digital data from the storage means to the buffer memory at a read speed higher than that output from the buffer memory to the outside, and a plurality of data stored in the storage means are controlled. The digital data of the file is output to the outside as continuous digital data.
[0021]
Therefore, control is performed to accumulate data in the storage unit at a writing speed higher than that input to the buffer memory, and the file is divided according to the timing of the division operation, so that a continuous signal is input. Even in this case, there is no missing portion in the record.
In other words, at the cueing position, although a certain time is required for the process of closing and opening the file such as stopping recording of the immediately preceding file and starting recording of the corresponding file, the time required for closing and opening the file is Since the sum of the time required for writing digital data is shorter than the time required for inputting digital data, there is no problem with continuous recording.
[0022]
On the other hand, since the digital data is read from the storage means to the buffer memory at a higher read speed than is output from the buffer memory to the outside, even when a plurality of files are continuously reproduced, the digital data is read at the moment of moving to the next file. Playback is not interrupted.
That is, at the cueing position, although a certain period of time is required for processing such as stopping reproduction of the immediately preceding file and starting reproduction of the corresponding file, the time required for closing and opening the file and the time required for reading digital data are reduced. Since the sum is shorter than the time required to output the digital data, there is no problem with continuous reproduction.
[0023]
Further, the recording / reproducing apparatus having such a configuration employs a file division method instead of an index mark file method in order to search for desired digital data among recorded digital data. Compatibility is ensured.
Also, for example, in the index mark file method, the number of cueing is consequently limited by the set number of indexes, and cueing cannot be performed beyond that number. However, in the file division method, the limit by the number of mark information is limited. Since there is no cueing position, a required number of cue positions can be provided.
As a result, it is possible to ensure compatibility between each model, to search for any number of tracks at any time while recording continuously, and to play back multiple files continuously. It is possible to realize a simple recording and reproducing apparatus.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a recording device, a reproducing device, and a recording and reproducing device according to an embodiment of the present invention will be described in detail with reference to the drawings.
[0025]
<Configuration of recording device and reproducing device and recording and reproducing device>
FIG. 1 is a block diagram showing a configuration of a recording / reproducing apparatus 100 capable of performing both recording and reproduction.
In FIG. 1, reference numeral 101 denotes control means as a system controller for controlling the operation of the entire recording / reproducing apparatus 100.
During recording, the control means 101 performs control for storing continuously input digital data stored in the buffer memory in the storage means at a higher writing speed than input to the buffer memory. The control is performed so that the file is divided according to the timing of the division operation from the operation input unit.
[0026]
Further, during reproduction, the control means 101 controls the digital data to be read from the storage means to the buffer memory at a higher read speed than that outputted from the buffer memory to the outside, and the data stored in the storage means is stored. Control is performed so that digital data of a plurality of files is output to the outside as continuous digital data.
[0027]
Reference numeral 110 denotes operation input means for performing various operation inputs.
In the operation input unit 110, in addition to recording and reproduction instructions, division input for dividing digital data at an arbitrary timing is performed.
Reference numeral 120 denotes a display unit for displaying various states of the apparatus, and displays various states required when inputting by the operation input unit 110.
[0028]
Reference numeral 130 denotes a memory controller which performs various controls in recording / reproducing in a buffer memory and a storage unit described later.
Reference numeral 140 denotes an A / D converter for converting an input analog audio signal into digital data.
Reference numeral 150 denotes a buffer memory for temporarily storing digital data at the time of input or output.
The buffer memory 150 is used for temporary storage when recording to a storage unit described later or when reproducing from the storage unit.
[0029]
Reference numeral 160 denotes a storage unit that stores digital data in a file format.
The storage means 160 may be built in the recording / reproducing apparatus 100 in a fixed state, or may be detachably mounted on the recording / reproducing apparatus 100.
The storage means 160 may be any of a semiconductor memory, a hard disk device, and a magneto-optical disk device.
[0030]
In the storage unit 160, control is performed by the memory controller 130 for accumulation at a higher writing speed than that input to the buffer memory 150.
Similarly, in the storage unit 160, the memory controller 130 performs control for reproducing data at a reading speed higher than that output from the buffer memory 150.
[0031]
Reference numeral 170 denotes a DA converter for converting digital data to be output into an analog audio signal and outputting the signal.
In the above description of FIG. 1, a specific example of a recording / reproducing apparatus capable of performing recording and reproduction has been described. However, a recording apparatus that does not include the DA converter 150 but only records, or an AD converter 140 A playback device that does not include a playback device only and constitutes a part of the embodiment of the present invention.
[0032]
<Recording operation of recording / reproducing device or recording device>
First, when there is a recording start instruction from the operation input unit 110, the control unit 101 gives a recording operation instruction to each unit.
When an audio signal such as a microphone input or a line input is input from an input terminal (not shown), the A / D converter 140 converts the audio signal into digital data according to a predetermined sampling frequency and the number of quantization bits.
For example, a sampling frequency of 44.1 kHz, 16-bit quantization, and two-channel digital data are generated. This digital data is stored in the buffer memory 150 (see FIGS. 2A and 2B).
[0033]
The digital data is temporarily stored in the buffer memory 150 and written to the storage unit 160 in a file format in accordance with the operation timing of the storage unit 160.
At this time, the memory controller 130 reads the digital data stored in the buffer memory 150 at a higher speed than at the time of storage and writes the digital data into the storage means 160 in order to increase the time for opening and closing the file. Control is performed (see FIGS. 2B, 2C, and 2D).
[0034]
When there is a division operation input from the operation input unit 110 while the voice signal is being input, the control unit 101 detects this fact and gives an instruction for division recording to the memory controller 130.
Here, the memory controller 130 interrupts the writing of the file N from the buffer memory 150 to the storage means 160 when the writing of the digital data at the timing of the division operation is completed, and writes the data to the storage means 160. The file N is closed (see FIG. 2D).
[0035]
Next, when the memory controller 130 completes the closing of the file N, the memory controller 160 opens the file N + 1.
Then, writing of digital data immediately after the instruction of division recording by the operation input means 110 is started as a file N + 1.
Similarly, when there is a division operation input from the operation input unit 110 again while the audio signal is being input, the control unit 101 detects this and gives an instruction for division recording to the memory controller 130.
[0036]
Here, the memory controller 130 interrupts the writing of the file N + 1 from the buffer memory 150 to the storage means 160 when the writing of the digital data at the timing of the division operation is completed, and writes the data to the storage means 160. The file N + 1 is closed (see FIG. 2D).
Next, when the memory controller 130 completes closing the file N + 1, the file N + 2 is opened in the storage unit 160.
Then, the writing of the digital data immediately after the instruction of the division recording by the operation input means 110 is started as the file N + 2.
[0037]
In this way, under the control of the control means 101 and the memory controller 130, each time a division operation is input, a new file starting from the division operation timing is generated and digital data is written. To
In this case, under the control of the control means 101 and the memory controller 130, a plurality of files in which continuous audio signals are divided and recorded are generated into files having file names having serial numbers in one directory and stored in the storage means 160. Accumulation is preferable from the viewpoint of file management.
[0038]
At this time, under the control of the control means 101 and the controller 130, information such as a file name and a file size is written in an area called a directory entry.
This kind of work is also executed in parallel with the above-described file closing and the like. In this case as well, the digital data stored in the buffer memory 150 is read out faster than at the time of storage and written into the storage means 160, so that it can be performed during idle time.
[0039]
On the other hand, in the example shown in FIG. 3, 10001. wav-10020. wav are accumulated in a directory called 20030410_02 and 200001. The example in which a plurality of files wav ~ are accumulated is illustrated.
In addition, wav is
Here, it is preferable to use a name (year, month, day), time, or the like for the directory, and it is desirable from the viewpoint of management that the file name be a serial number in the directory.
However, it is not limited to this.
[0040]
Therefore, control is performed to accumulate the data in the storage unit 160 at a writing speed higher than that input to the buffer memory 150, and the file is divided according to the timing of the division operation. Even if the recording is performed, there is no missing portion in the record.
In other words, at the cueing position, a certain time is required for the process of closing and opening the file, such as stopping recording of the immediately preceding file, starting recording of the corresponding file, and the time required for closing and opening the file. There is no problem with the time required for reading and the continuous input of signals.
[0041]
Further, in this recording apparatus, a file division method is adopted for cueing instead of the index mark file method, so that compatibility between the respective models is ensured.
Also, since the number of marks for cueing is set in advance as in the index mark file method, the number of cueing is limited as a result. However, this recording apparatus employs a file division method. Therefore, a desired number of cue positions can be provided.
As a result, it is possible to realize a recording apparatus that can ensure the compatibility between the respective models, and can perform an arbitrary number of cueing at an arbitrary timing while performing continuous recording.
[0042]
<Playback operation of recording / playback device or playback device>
Here, a continuous operation of a plurality of files will be described first as a reproducing operation.
When a file of digital data is already stored in the storage unit 160 and an instruction to start reproduction (start of continuous reproduction) is given from the operation input unit 110, the control unit 101 gives an instruction of a recording operation to each unit.
[0043]
In this case, if a specific file name is input to the operation input unit 110, a file with the input file name is input. If no file name is input, a file with a lower number (earlier recording time) is input. It is opened from the storage means 160, read out, copied to the buffer memory 150, and then closed (see FIG. 4A).
In addition, in order to allow continuous playback operation while opening and closing the file, the memory controller 130 converts the digital data stored in the storage unit 160 to a speed higher than the required speed at the time of normal speed audio output. The control is performed such that the data is read at high speed and copied to the buffer memory 150 (see FIGS. 4A, 4B, and 4C).
[0044]
Here, the memory controller 130 opens the file M in the storage unit 160, reads out the file M, copies it to the buffer memory 150, and then closes it.
Then, the memory controller 130 causes the DA converter 170 to output the file M in the buffer memory 150 at a normal speed. As a result, an audio signal is output from the DA converter 170 at the same normal speed as during recording.
[0045]
On the other hand, while the file M is being output from the buffer memory 150, the memory controller 130 starts opening the file M + 1 next to the file M, reads out the file M + 1, and starts copying the file M + 1 to the buffer memory 150.
Further, the memory controller 130 causes the DA converter 170 to output the file M + 1 in the buffer memory 150 at a normal speed at the same time when the output of the file M from the buffer memory 150 ends.
[0046]
By doing so, a plurality of files stored in the storage means 160 are reproduced in a continuous state without missing.
Therefore, since the digital data is read from the storage means 160 to the buffer memory 150 at a higher reading speed than the output from the buffer memory 150 to the outside, even when a plurality of files are continuously reproduced, the next file is read. There will be no interruption of playback at the moment of transition to.
[0047]
That is, at the cue position, a certain time is required for file close and open processing such as stop of reproduction of the immediately preceding file and start of reproduction of the corresponding file. Since the sum of the required times is shorter than the time required for the reproduction output, there is no problem with continuous reproduction.
Furthermore, in this reproducing apparatus, a file division method is adopted instead of an index mark file method for cueing, so that compatibility between respective models is ensured.
Also, regardless of the limitation of the number of mark information as in the index mark file system, it is possible to reproduce the necessary number of cue positions.
[0048]
As a result, it is possible to realize a reproducing apparatus that can search for an arbitrary timing while ensuring compatibility between the models and that can continuously reproduce a plurality of files.
In the above case, if a specific file name is first specified on the operation input unit 110, the specified file is located at the beginning of the file, and thereafter, the file is reproduced continuously.
[0049]
On the other hand, if a specific file name is specified on the operation input unit 110 and a single reproduction instruction is given, only that file is reproduced with the specified file located at the beginning. Become.
In the above-described embodiment, an example is described in which the audio signal is stored in the storage unit 160 as digital data in the wave format, but the data format is not limited to this.
That is, there may be digital data of another format or compressed digital data.
[0050]
Further, the recording device, the reproducing device, and the recording / reproducing device according to the above-described embodiment can be applied not only to audio signals but also to video signals, and similar effects can be obtained.
[0051]

The digital data of the plurality of files is output to the outside as continuous digital data.
Therefore, since digital data is read from the storage means to the buffer memory at a reading speed higher than that output from the buffer memory to the outside, even when a plurality of files are continuously reproduced, the moment when the next file is transferred is returned. There will be no interruption in playback. That is, there is no problem even if a certain time is required at the cueing position for processing such as stopping reproduction of the immediately preceding file and starting reproduction of the file.
[0054]

[0056]
Therefore, control is performed to accumulate data in the storage unit at a writing speed higher than that input to the buffer memory, and the file is divided according to the timing of the division operation, so that a continuous signal is input. Even in this case, there is no missing portion in the record. That is, there is no problem even if a certain period of time is required for closing the file and opening the file such as stopping recording of the immediately preceding file and starting recording of the file at the cueing position.
Also, since digital data is read from the storage means to the buffer memory at a higher read speed than is output from the buffer memory to the outside, even when a plurality of files are continuously reproduced, the moment when the next file is moved to the next file. There will be no interruption in playback. That is, there is no problem even if a certain time is required at the cueing position for processing such as stopping reproduction of the immediately preceding file and starting reproduction of the file.
