The headphone terminal 19 is provided.

  The key input unit 13 and the display unit 14 constitute a user interface, and the user can give necessary instructions to the CPU 11 via the key input unit 13 while viewing the display on the display unit 14. The CPU 11 performs digital signal processing such as encoding and applying a sound effect to the digital audio signal from the AD converter 17 in accordance with an instruction given via the key input unit 13, and the memory unit 12, DA converter 18, USB It can be supplied to the terminal 15. Further, music data can be read from a USB memory connected to the memory unit 12 or the USB terminal 15, subjected to necessary signal processing, and supplied to the USB memory, the memory unit 12, or the DA converter 18. For example, when an instruction to perform recording using a microphone is given from the user via the key input unit 13, the CPU 11 encodes a digital audio signal input via the microphone terminal 16 and the AD converter 17. Recording is performed from the microphone by performing the above process and writing the data in the memory unit 12 in a predetermined file format.

  The recording device has a schedule management function realized by the CPU 11 in accordance with a predetermined program. A predetermined genre for the schedule can be set for each schedule data handled in the schedule management function. Examples of the genre include “conference”, “music”, “going out”, and “banquet”. The genre is set by the user selecting from a drop-down list or the like when inputting each schedule. The recording device also has a function of setting a recording format applied to the recording based on the user's instruction or the user's schedule data corresponding to the recording start time before starting the recording. As the recording format, for example, the format and bit rate of a file for storing recording data are applicable.

  FIG. 2 shows an example of a schedule management screen displayed in the schedule management function. In the figure, 21 indicates the date of the schedule being displayed on the screen, 22 indicates an operation button for changing the displayed schedule to the date of the previous day, and 23 indicates the schedule to be displayed on the next day. A display of operation buttons for changing to a date, 24 an operation bar for sending back and forth the time zone of the schedule to be displayed, and 25 a schedule content display area for each time zone. A touch panel constituting the key input unit 13 is provided on the surface of the schedule management screen, and operation using the operation buttons 22 and 23 and the operation bar 24 is possible.

  The user can display a desired date schedule by operating the button graphics 22 and 23. The date of the displayed schedule can be confirmed by the date display 21. By operating the bar graphic 24, the screen display can be scrolled up and down to display a schedule for a desired time zone. Furthermore, by pressing the display area 25 of the schedule content in a desired time zone, it is possible to shift to an edit mode for editing the schedule in that time zone. Various keys constituting the key input unit 13 can be used for editing. When editing, the above-described drop-down list or the like is displayed, and the genre can be set for the schedule being edited by selecting the genre. When editing is completed, a schedule is set according to the edited content. FIG. 2 shows a state in which the contents of the schedule set in the time zone of 15:00 to 16:00 and the time zone of 18:00 to 19:00 are displayed. As the genre of the schedule, “meeting” is set for the schedule of 15:00 to 16:00, and “music” is set for the schedule of 18:00 to 19:00.

  Such a schedule management function is realized by schedule management software such as in a PDA (Personal Digital Assistant). The set schedule data is recorded in the memory unit 12. If such schedule management software is not provided, another device having a schedule management function, such as a personal computer, a PDA, a mobile phone, or a mini component, is connected via the USB terminal 15 and is connected to the device. The schedule data may be transferred to the memory unit 12 for storage and use. Further, the other device may be connected via the USB terminal 15 so that schedule data stored in the device can be referred to.

  FIG. 3 shows an example of the definition table stored in the memory unit 12. This table defines the recording format corresponding to each genre of the schedule of the art. Here, as the recording format, a file format and a bit rate of recording data (sampling frequency in the case of PCM) are defined. The CPU 11 can change the contents of this table in response to a user instruction. When an instruction to start recording is given, the CPU 11 belongs to the time zone of any schedule set by the schedule management function, and any genre in FIG. 3 is set for the schedule. If so, recording is performed in a recording format corresponding to the genre.

  For example, according to the example of FIG. 2, when a recording instruction is given between 15:00 and 16:00 on September 1, 2008, the genre for the schedule in that time zone is set to “conference”. Therefore, according to the definition of FIG. 3, recording is performed at a bit rate of 128 [kbps] according to the MP3 file format. Further, when a recording instruction is given at 18:15 on September 1, 2008, the genre for the schedule of the time zone to which the time point belongs is set to “music”, so according to the definition of FIG. Recording is performed at a sampling frequency of 44.1 [kHz] by PCM. When there is no schedule data at the start of recording or when there is no genre setting, the MP3 format is used in accordance with the default values defined in the definition table in FIG. 3 unless the user instructs the recording format. , Recording is performed at a bit rate of 96 [kbps].

  FIG. 4 is a flowchart showing an example of a recording process performed by the CPU 11. This process is performed according to a predetermined program. When processing is started in response to an instruction to start recording by the user, the CPU 11 first determines in step 41 whether or not the user has instructed a recording format. If it is determined that there is an instruction, in step 46, the recording format is set in accordance with the instruction, and then recording is started in step 48. If it is determined that there is no instruction from the user, the process proceeds to step 42 to determine whether the schedule data can be referred to. For example, in a case where schedule data stored in another device is referred to, it is determined that reference is not possible when the other device is not connected.

  If it is determined that the schedule data can be referred to, it is determined in step 43 whether there is schedule data related to the current time. The schedule data related to the current time is schedule data set for a time zone to which a time point when the user instructs to start recording belongs. For example, in the example of FIG. 2, if there is an instruction to start recording at 15:30, the “patent conference room D” set for the time zone from 15: 00 to 16: 00 Applicable.

  If it is determined that there is schedule data related to the current time, the process proceeds to step 44, where it is determined whether or not a genre is set for the schedule data and a recording format corresponding to the genre is defined in the definition table. judge. If it is determined that it is defined, the process proceeds to step 45, a recording format is set according to the definition, and then recording is started in step 48.

  When it is determined in step 42 that it is not possible to refer to schedule data, when it is determined in step 43 that there is no schedule data related to the current time, and in step 44 it is determined that there is no corresponding recording format definition. In step 47, the recording format defined as the default value in the definition table is set, and then recording is started in step 48.

  After the recording is started, if an instruction to end the recording is detected in step 49, the recording is ended and the processing of FIG. 4 is ended.

  According to the present embodiment, when a recording start instruction is given, recording is performed according to the recording format defined for the genre set in the corresponding schedule. Can be recorded in various recording formats.

  FIG. 5 is a flowchart showing another example of the recording process by the CPU 11. FIG. 6 shows an example of a definition table referred to in this process. In this table, the corresponding conference mode, music mode, and recording format of the outing mode are defined for each predetermined character string related to the meeting, music, and outing. As a character string related to the conference, for example, “conference”, “class”, “talk”, and “meeting” are applicable. Examples of character strings related to music include “instrument”, “studio”, “live”, and “concert”. Examples of character strings related to going out include “outing”, “walking”, and “shopping”.

  When the recording process is started in response to an instruction to start recording by the user, the CPU 11 first determines in step 51 whether or not there has been an instruction about the recording format by the user. If it is determined that the instruction has been given, in step 52, the recording format is set in accordance with the instruction, and then recording is started in step 61. If it is determined that the instruction has not been given, the process proceeds to step 53 to determine whether the user's schedule data can be referred to. If it is determined that the reference is not possible, the process proceeds to step 60, where the recording format is set to the default mode (MP3, 96 [kbps]) in the definition table of FIG.

  If it is determined in step 53 that the schedule data can be referred to, the process proceeds to step 54, and in the schedule data in the time zone to which the present time belongs, whether or not there is a character string related to the meeting in the definition table of FIG. Determine whether. If it is determined that it exists, the recording format is set to the conference mode (MP3, 128 [kbps]) based on the definition table of FIG. 6 in step 55, and recording is started in step 61. For example, in the case of the example of FIG. 2, if the current time is 15: 5, “conference” exists in the corresponding schedule data, so recording starts in the recording format of the conference mode.

  If it is determined in step 54 that there is no character string related to the conference, the process proceeds to step 56 to determine whether or not there is a character string related to music in the schedule data in the time zone to which the present time belongs. If it is determined that there is a character string related to music, the recording format is set to the music mode (PCM, 44.1 [kHz]) in step 57, and recording is started in step 61. For example, in the case of the example of FIG. 2, if the current time is 18:00:00, “instrument” and “studio” exist in the corresponding schedule data, so recording is started in the recording format of the music mode. .

  If it is determined in step 56 that there is no character related to music, the process proceeds to step 58 to determine whether or not there is a character string related to going out in the schedule data of the time zone to which the present time belongs. If it is determined that there is a character string related to going out, the recording format is set to the outing mode (MP3, 256 [kbps]) in step 59, and recording is started in step 61. When recording is started, the recording process in FIG. 5 is terminated.

  According to this recording process, when there is an instruction to start recording, the recording format is set to the conference mode, the music mode, or the outing mode based on whether a predetermined character string exists in the corresponding schedule data, Since the recording is started, if the schedule is set when the recording start instruction is given, the user simply gives the recording start instruction, and the recording is performed in the recording format suitable for the schedule content at that time. It can be carried out.

  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, the type of the recording device was not mentioned, but the recording device has a recording function, can refer to schedule data, and can set the recording format, The present invention can be applied. For example, the present invention can be applied to DAP, component stereo, and a PDA having a recording function.

  Further, as described in claim 4, when referring to schedule data stored in another device, the schedule data may be managed by a plurality of users, or a plurality of schedule data. Schedule data to be used may be selected.

  In the above description, the recording format that can be set has been described with respect to the file format and the bit rate. However, the recording format is not limited to this, and the recording format may be stereo or monaural, or the sound effect to be applied. May be. For example, as the above-described conference mode recording format, a recording format that uses monaural recording may be adopted. Further, it may be related to whether or not to set a break (cue point) and a parameter that defines a break interval. For example, as a parameter value corresponding to the conference mode, a parameter value that defines a predetermined interval as a delimiter interval may be adopted so that recording results can be easily searched and edited.
