JP5035233B2 - Audio device, program, and delimiter information adding method - Google Patents

Description

  The present invention relates to an audio apparatus having a function of adding delimiter information to recorded data, a program for causing a computer to function as each means in the audio apparatus, and a delimiter information providing method suitable for the audio apparatus.

  In recent years, digitally recordable devices such as digital portable players have become widespread. Also, in the case of a voice recorder or the like, digital recording data may be moved to a personal computer and then edited by a personal computer application. In such editing, a track mark is added or an unnecessary part is deleted while actually reproducing a recorded file and listening to the reproduced sound. Further, in the above-described digital portable player and voice recorder, it is possible to record for a long time by encoding the digital recording data into a predetermined compression format and increasing the capacity of the built-in memory.

  As a technique for providing a track mark, for example, a technique is known in which a track mark is provided so as to prevent data loss at the start of recording (see, for example, Patent Document 1). In this technology, when audio data input from the outside is recorded on an MD (mini disc), recording is always performed cyclically using an unused area before a recording start request is actually given. When a start request is received, a temporary track mark is assigned, the audio data recorded so far is used as the first track, the audio data recorded after the provision of the temporary track mark is used as the second track, and thereafter The position of the track mark is adjusted so that it is possible to select whether or not the second track is a regular track and the first track is a regular track.

  According to the present invention, it is possible to efficiently add separation information to recorded data.

  FIG. 1 is a block diagram showing a configuration of an audio apparatus according to an embodiment of the present invention. As shown in the figure, this apparatus has a CPU 11 that controls each part of the apparatus, a DA converter 12 that converts a digital audio signal from the CPU 11 into an analog audio signal, and reads out data recorded on a CD and outputs an analog audio signal A selector unit 15 that selects and outputs one of the inputs from the CD unit 13, the tuner unit 14 that receives broadcast radio waves and outputs an analog audio signal, the DA converter 12, the CD unit 13, and the tuner unit 14; An amplifying unit 16 that amplifies the analog audio signal from the selector 15, an output unit 17 that outputs the audio signal amplified by the amplifying unit 16 or audio based on the audio signal, and an operating unit 18 for giving an operation instruction to the CPU 11. A display unit 19 for displaying an image based on image data from the CPU 11, a storage unit 20 accessed by the CPU 11, and The rush memory 21, the interface unit 22 for the CPU 11 to access the external device, the microphone terminal 23 for connecting the microphone, and the analog audio signal from the microphone connected to the microphone terminal 23 are converted into a digital audio signal to convert the CPU 11. An AD converter 24 is provided.

  As an audio apparatus, for example, a minicomponent, a PDA (personal digital assistant), a portable recorder, and a voice recorder having a schedule management function that can generate, edit, and browse schedule data in a predetermined format are applicable. . The storage unit 20 is composed of a large-capacity hard disk, a built-in memory, and an external storage medium memory such as a memory card and a USB memory, and stores music files, recording files, image data, schedule data, and the like. The interface unit 22 includes, for example, a USB controller and a USB terminal, and is used to connect a portable recorder or the like. The output unit 17 includes a headphone terminal, a speaker or a speaker terminal, or an external output terminal. The operation unit 18 is used by a user to operate the audio device, and includes a button, an optical operation device, a touch screen, a keyboard, and the like. The display unit 19 visually displays the operation state of the audio device, the file name, and the like. In addition, an image or a moving image reproduced based on the image data or moving image data is displayed.

  The operation unit 18 and the display unit 19 constitute a user interface, and the user can give necessary instructions to the CPU 11 via the operation unit 18 while viewing the display on the display unit 19. The CPU 11 can selectively switch the audio signal from the CD unit 13, the tuner unit 14, or the DAC 12 by the selector 15 according to the given instruction, and supply the audio signal to the amplifier unit 16 for output. The CPU 11 can also read music data and recording data from the storage unit 20 and the flash memory 21, perform necessary signal processing, and supply a digital audio signal to the DA converter 12. When the CPU 11 is further instructed to perform recording using a microphone, the digital audio signal input through the microphone terminal 23 and the AD converter 24 is subjected to processing such as encoding into data of a predetermined format, Recording from the microphone is performed by writing into the storage unit 20 or the flash memory 21.

  FIG. 2 shows an example of a schedule browsing screen displayed on the display unit 19. In the figure, 25 is a date display column for displaying the date of the schedule being displayed, 26 is a time zone display column for displaying the time zone of the schedule every hour, and 27 is the contents of each schedule item together with the start time. The item display field 28 to be displayed is a bar graphic that visually represents the position of the schedule being displayed in all the browseable schedules. In the figure, a schedule in the time zone from 13:00 to 15:00 is displayed. The schedule to be displayed can be changed by scrolling the screen. The surface of the display unit 19 may be a touch panel, and the screen may be scrolled by operating the bar graphic 28.

  This schedule browsing screen is displayed based on the schedule data stored in the storage unit 20. In the schedule data, the contents of each schedule item and the start time are registered for each date.

  When recording from the microphone according to the user's instruction, the audio device refers to the schedule data in the storage unit 20 and records each time the time indicated by the built-in time measuring means matches the start time of each schedule item. A track mark is assigned to the data inside. For example, if the schedule data has the contents shown in FIG. 2 and recording starts at 12:58 and continues until 14:55, 13:00 is set as a schedule item during the recording period. Since there is a “planning meeting” from 00 minutes, a “planning adjustment meeting” from 13:20, a “commercialization meeting” from 14:00, and a “product AA specification decision meeting” from 14:30, FIG. As shown in the figure, track marks are assigned to the locations corresponding to 13:00, 13:20, 14:00, and 14:30 in the recorded data. The track mark may be recorded in the audio signal, such as that provided as a silence signal part, but the track mark may be editable, such as that provided as an elapsed time or address from the recording start point. preferable. Further, it may be a track number and its start address in the UTOC information in the case of MD (mini disk).

  FIG. 4 is a flowchart showing a process for realizing such track mark assignment. This process is performed by the CPU 11 according to a predetermined program. That is, when the process is started, the CPU 11 first waits in step 41 until the user gives an instruction to start recording. When an instruction to start recording is given, the process proceeds to step 42 to determine whether the schedule data can be referred to. That is, if schedule data that can be referred to exists in the storage unit 20 or the flash memory 21, it is determined that the data can be referred to.

  If it is determined that reference is possible, the schedule data is read onto the main memory in step 43. Next, in step 44, the recording file generation is started. That is, recording of the recording data to the recording file is started. As the file name of the recording file, for example, a name indicating the recording start time is used.

  Next, in steps 45 to 47, a process of assigning track marks is performed until recording is completed. That is, the arrival of a time that coincides with the start time of each schedule item in the schedule data is monitored (step 46), and a track mark is assigned to the recording data being recorded at the time when the coincidence time arrives. (Step 47) The process is performed until an instruction to end the recording is given (Step 45).

  On the other hand, if it is determined in step 42 that the schedule data cannot be referred to, generation of a recording file is started in step 48, and in step 49, it waits for an instruction to end recording.

  If it is determined in step 45 or 49 that an instruction to end recording is given, the process proceeds to step 50, and the recording file generation is ended. That is, recording of the recording data is stopped and the recording file is closed. Thereby, the process of FIG. 4 is completed.

  According to the recording file generated in this way, even if it relates to continuous recording over a long period of time, the track mark is automatically given based on the schedule data. Recording files can be divided and searched based on the track marks without performing a position search.

  Also, since the track mark can be edited by the user, for example, even when a “commercialization meeting” from 14:00 actually starts at 14:06, a long recording file is fast-forwarded from the beginning. Thus, it is not necessary to cue the portion related to the “commercialization meeting”, and the cueing is performed by fast-forwarding from the track mark position at 14:00, and the track mark at 14:00 is erased and the time is 14:06. Since it is only necessary to reassign track marks to minutes, it is possible to easily manage recorded files.

  Furthermore, a dedicated playlist may be generated for the generated recording file. For example, a recorded file that has been automatically given the above-mentioned track mark and further modified by the user is displayed as a playlist, and when the user selects one of the recorded files from the list, As information about the recording file, the time corresponding to each track mark and the contents of the schedule item are displayed in a list, and when any schedule item in the list display is selected, the recording file part corresponding to the schedule item is selected. You may make it perform reproduction | regeneration.

  In order to achieve this, the recording file is stored in the playlist folder “record”, and each recording file corresponds to the schedule item and its start time (that is, each track mark position attached to the recording file). Recording time) in association with the recording file. Further, when the track mark of a recording file is changed, deleted, or added, the result needs to be reflected in the recording accompanying information of the recording file. The CPU 11 can record such recording-accompanying information when adding a track mark (steps 46 and 47). The recording-accompanying information can be recorded as metadata of a corresponding recording file, for example. A table for recording the recording-accompanying information may be provided separately.

  Note that the start time of each schedule item included in the recording-accompanying information indicates the position from the beginning of the recording file by subtracting the recording start time recorded as the file name of the corresponding recording file. That is, itself can serve as a track mark. Therefore, when recording-accompanying information is recorded, the process itself may be regarded as applying a track mark, and the process of adding a track mark may be omitted. That is, when performing playback based on the schedule item selected from the above list display, based on the corresponding start time in the recording-accompanying information and the file name of the associated recording file (recording start time), Playback from the schedule item portion in the recording file can be started.

  FIG. 5 shows an example of screen transition in the case where playback is performed based on the selection from the list of schedule items described above. The screen of FIG. 10A is a folder selection screen for displaying a list of selectable folders and accepting the folder selection. The screen of FIG. 6B is a screen that is displayed when “record” is selected on the folder selection surface, and displays a list of file names of recording files in the folder “record” and selects a recording file. It is a recording file selection screen for accepting. The screen of FIG. 6C is a screen that is displayed when a recording file is selected on the recording file selection screen, and displays a list of schedule items corresponding to the recording file and accepts selection of the schedule item. It is a schedule item selection screen. 51 in the figure is a cursor graphic for selecting a selection item on each screen. The user can select the selection item by moving the cursor 51 onto a desired selection item with a predetermined operator and pressing a predetermined confirmation button.

  When “Folder” is selected on the predetermined menu screen displayed on the display unit 19, the CPU 11 switches the menu screen to the folder selection screen shown in FIG. When “record” is selected on the folder selection screen, the folder selection screen is switched to the recording file selection screen shown in FIG. The recording file selection screen is displayed by displaying a list of file names of the recording files existing in “record”. When the recording file “20081217125836.wav” is selected on the folder recording file selection screen, the recording file selection screen is switched to the schedule item selection screen in FIG. The display of the schedule item selection screen is performed based on the recording-accompanying information associated with the recording file “20081217125836.wav”. When any schedule item is selected on the schedule item selection screen, reproduction is started from a portion corresponding to the start time of the selected schedule item in the recording file based on the recording accompanying information. Assuming that the selected recording file “20081217125836.wav” is a recording file to which the track mark described with reference to FIG. 3 is given, when “commercialization meeting” is selected on the schedule item selection screen, the recording file is recorded. Playback is started from the location corresponding to 14:00 in the file (the location after the track mark is changed to the location corresponding to 14:06 as described above). The file name displayed on the recording file selection screen indicates the recording start time of the corresponding recording file. For example, the file name “20081211725836.wav” indicates that the recording start time of the corresponding recording file is 12:58:36 on December 17, 2008.

  FIG. 6 is a flowchart showing another process for assigning a track mark to a recording file. Also in this case, the processing is performed by the CPU 11 according to a predetermined program. However, a track mark is added to a recording file that is recorded by a portable recorder or DAP (digital audio player) connected via the interface unit 22 and transferred to the storage unit 20 after being transferred from the portable player or the like. Is done.

  That is, when processing is started, the CPU 11 first waits for connection of a DAP or the like via the interface unit 22 in step 61. If it is detected that a DAP or the like is connected, the process proceeds to step 62, and it is determined whether or not a recording file exists in a folder having the name “record” in the memory such as the DAP. If it is determined that it does not exist, the processing in FIG. If it is determined that it exists, the process proceeds to step 63 and the recorded file in the folder is transferred to the storage unit 20.

  Next, in step 64, it is determined whether or not predetermined schedule data can be referred to. That is, if schedule data that can be referred to exists in the storage unit 20 or the flash memory 21, it is determined that the data can be referred to. If it is determined that the reference is not possible, the processing of FIG. 6 is immediately terminated. If it is determined that it can be referred to, the process proceeds to step 65 to read the schedule data onto the main memory.

  Next, in step 66, it is determined whether or not there is a schedule item including the start time in the time zone from the recording start time to the end time related to the transferred recording file in the schedule data. This determination is made, for example, by comparing the recording start time recorded as the file name of the recording file, the recording end time obtained from the recording start time and the capacity of the recording file, and the start time of each schedule item in the schedule data. This can be done. As a specific example of this file name, for example, a recording file is related to a recording started at 12:58:36 on December 17, 2008 by DAP and ended at 14:55 on the same day. Then, “20081217125836.wav” corresponds. However, “.wav” is an extension indicating that the file format is the WAV format.

  If it is determined in step 66 that the corresponding schedule item does not exist, the processing of FIG. 6 is immediately terminated. If it is determined that the corresponding schedule item exists, the process proceeds to step 67, and a track mark is assigned to the transferred recording file at a position corresponding to the start time of each corresponding schedule item based on the schedule data. When the assignment of the track mark is completed, the processing in FIG. 6 is terminated.

  Even in this case, when assigning track marks, for each recording file, the contents of the schedule item corresponding to each assigned track mark and its start time are stored in association with the recording file as accompanying information, and thereafter By reflecting the change, addition or deletion of the track mark in the accompanying information, it is possible to reproduce from the recording file portion corresponding to any schedule item by the method described with reference to FIG.

  As described above, according to the present embodiment, since the track mark is given to the recording file based on the schedule data, the recording file can be moved from the position corresponding to the start time of any related schedule item. Can be easily reproduced. Also, when recording data is acquired from another device, since track marks are added later, similarly, playback can be performed from a position corresponding to the start time of an arbitrary schedule item.

  Furthermore, when assigning track marks, the corresponding schedule item and its start time are recorded as recording-accompanying information in association with the recording data, so each schedule item is displayed as a selection item, and the selection is made. By accepting, based on the recording accompanying information and the recording start time attached to each recording file, the corresponding recording data can be reproduced from the portion corresponding to the selected schedule item.

  Note that the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, in the above description, as a means for adding delimiter information to the recording data, a method of adding a track mark to the recording file is used. Instead, the delimiter information is divided by dividing the recording data into different files. You may make it provide. For example, every time the start time of each schedule item included in the recording period arrives, a new file with a file name including the start time and contents of the schedule item is sequentially generated, and the recording data is divided into files. You may make it record. In this case, the recording-related information described above can be recorded by recording the corresponding schedule item and its start time in the file name of each file constituting one recording data.

  Further, in the above description, the schedule data is held by the audio device, but the schedule data may be recorded in another device instead. In this case, the audio device can refer to the schedule data when another device is connected to the audio device.

  In step 52 in FIG. 6, the recording start time information for the recording file transferred from the DAP to the audio device is recorded as the file name of the recording file. It may be recorded as metadata.

  In the above, recording of information such as the track mark, recording start time, corresponding schedule item, and start time of the recording file is performed in the file name, metadata and other areas. Information may be managed collectively as one database. For example, for each recording file, a file “table” for storing a recording file is stored in a table file in which items such as a file name, a recording start time, a recording end time, and corresponding schedule items and their start times are provided. The data of each item obtained may be additionally registered every time recording is performed or recording files are transferred from other devices. Using such a database, a list of registered file names is displayed, each schedule item corresponding to the selected file name is displayed, and the part corresponding to the selected schedule item is played back. May be. In addition, for editing track marks, a list of registered file names is displayed using such a database, and a graphic showing the position of each track mark as shown in FIG. 3 is displayed for the selected file name. Then, change, deletion, and addition of the track mark position may be accepted by a user interface using this graphic, and the result may be reflected in the database.
