The audio signal is recorded in an appropriate data format on the CD-R 4 loaded in the CD-R drive 3. Therefore, the guest room PC 2 operates as a control unit in the karaoke recording apparatus 1 having the above configuration. FIG. 2 shows that the guest room PC 2 is a karaoke recording device 1.
Is a functional block diagram when operating as a control unit. The main body 10 of the guest room PC 2 is a CPU, RAM, RO
M and the like, a central control unit 11 constituted by a computer, a hard disk device 12, an RS232C
Standard control information interface 13, SCSI interface 1 serving as interface with CD-R drive 3
5. A recording input interface 14 for processing audio signals from the karaoke apparatus 5 and the like are incorporated as main components. The recording input interface 14 has a voice input terminal, inputs a mixed voice signal of karaoke accompaniment music and singing voice output from a voice output terminal of the karaoke apparatus 5 from this voice input terminal, and samples the mixed voice signal. The data is converted into PCM data and transferred to the central control unit 11. The guest room PC 2 has, as input devices operated by the user, a touch panel 23 provided on a screen of a display 20 in addition to a keyboard 21 and a mouse 22. Operation input information from these input devices is Are transferred to the central control unit 11 via the interfaces 16 to 18 of the respective standards. Graphic control unit 19
Converts the bitmap image developed in the built-in video RAM into a video signal and outputs the video signal to the display 20. In this embodiment, when the guest room PC 2 functions as the control unit of the karaoke recording apparatus 1, most of the operation is received from the touch panel 23. The guest room PC 2 has a GUI environment for appropriately switching the display screen of the display 20 in response to a user input from the touch panel 23. The user uses the karaoke recording service through a GUI-based interactive user interface. On the other hand, the karaoke apparatus 5 for supplying the recording source to the guest room PC 2 is a known communication karaoke performance terminal,
For a large number of karaoke songs identified by song numbers (song IDs), music generation data described in MIDI format and lyrics rendering data from which lyrics images are generated are stored in an appropriate external storage. Then, music generation data and lyrics depiction data corresponding to the music ID specified by the user are processed to generate the karaoke accompaniment music and the lyrics image in synchronization. In addition, the singing voice of the user input through the microphone and the karaoke accompaniment music are mixed and the voice signal is output as sound. The lyrics image is output as an image to a display attached to the karaoke apparatus 5. === Outline of Karaoke Recording Function === The karaoke recording apparatus of the present invention appropriately converts a voice signal from the karaoke apparatus as a recording file for each music piece in response to a case where the singing content is unsatisfactory. "Temporary recording" by temporarily writing to the storage device. Then, a user input to transfer (dump) the provisionally recorded content to a portable recording medium is received, and the corresponding recording file is written to the portable recording medium. Further, with respect to karaoke music whose recording is prohibited by copyright, consideration is also given to the fact that the accompaniment music is not written on a portable recording medium. In this embodiment, the hard disk device 12 is used as a storage device for temporarily storing the recording file, and the CD-R4 is adopted as a portable recording medium. As a recording control in consideration of copyright, a recording permission / prohibition information table in which a music ID and recording permission / non-permission information are associated with each other is prepared and stored in the hard disk device 12 in advance. When the music ID of the karaoke accompaniment music to be provisionally recorded is received via the information interface 13, the ID is referred to the table, and if the ID is associated with data indicating that recording is permitted, the provisional recording is performed. The method of validating the operation is adopted. Hereinafter, the recording operation by the karaoke recording device 5 will be described. === Karaoke Recording Operation === When the user operates the guest room PC 2 and inputs that the karaoke recording service is to be used, the guest room PC 2 starts karaoke music played by the karaoke apparatus 5 after the input. , A music start timing, a music ID, and the like are acquired through the control information interface 13. The guest room PC 2 acquires the music ID of a certain karaoke music before the performance of the music starts, and
Next, it is confirmed whether or not the recording is permitted by the recording permission / inhibition information table. If the recording is not permitted, the fact is displayed on the display 20 of the guest room PC2. If permitted, an appropriate area of the RAM is secured as a recording data storage area, and PCM data from the recording input interface is stored in this area. The storage of the PCM data is stopped at the end timing of the music performance, for example, when the end signal of the music performance is received from the karaoke apparatus 5. When the data storage operation is stopped, a screen for inquiring the user as to whether or not to save the recorded contents is displayed on the display 20. If a storage instruction is given, the stored PCM data includes a music ID and the like as appropriate. The file is created in a recording file of a predetermined format (such as a WAV file), and the file is stored in an appropriate recording area (directory, folder, etc.) of the hard disk drive 12 and provisionally recorded. Of course, if the capacity of the RAM is sufficiently large, the recording file may be directly stored in the RAM without being transferred to the hard disk device 12. On the other hand, if an instruction not to save the recorded content is input within a fixed time after the performance or during the performance due to a failure in singing or the like, the PC stored in the RAM is read.
Erase M data. Alternatively, the previous data is overwritten with PCM data input at the next performance opportunity. A plurality of recording files respectively created at several performance occasions as described above are stored in the hard disk drive 12, and the user temporarily writes the temporarily recorded files to the CD-R4 by "dump". Request ”in guest room PC2
, The CD-R drive device 3 is controlled, and the corresponding recording file is written (dumped) on the CD-R 4 according to the music CD format. In the present embodiment, the number of music pieces that can be temporarily recorded is determined in advance, and when recording files for the number of music pieces have been created, a screen prompting writing to the CD-R4 is displayed on the display 20 and a dump request is issued. To write a recording file to the CD-R4. Of course, even if the number of recorded files is less than the limited number of songs, a dump request from a user is accepted at any time. In this embodiment, the hard disk drive 1
Since the recording file 2 is a non-volatile storage device, when the temporarily recorded recording file is written to the CD-R 4, the recording file in the hard disk device 12 is erased so that the recording file is not illegally taken out. Even in the case of temporary recording in the RAM, the data is stored unless the power supply of the guest room PC 2 is turned off, so that consideration must be given to actively erasing the recorded contents. The provisionally recorded recording file may be deleted not immediately after writing to the CD-R 4 but may be deleted when the power supply of the guest room PC 2 is turned off or by a predetermined operation input. === Other Embodiments === In the above embodiment, one karaoke apparatus and one karaoke recording apparatus are used.
It was a form corresponding to one to one. However, if a computer system including a CD-R drive device is attached to each karaoke device, a store having many karaoke devices would spend a lot of capital investment. In addition, maintenance and management become complicated. Therefore, an embodiment for centrally managing mixed audio signals from a plurality of karaoke apparatuses will be described. FIG. 3 schematically shows an embodiment of the karaoke recording apparatus of the centralized management system. A guest room PC 2 is individually connected to each karaoke device 5. The processing of the guest room PC2 is the same as that of the guest room PC of the above embodiment.
Each guest room PC 2 is connected by a LAN to a computer (management PC) 6 having the CD-R drive 3 attached thereto. The guest room PC 2 creates a recording file for each karaoke device 5. When the guest in each guest room performs a dump request operation of the recording file, the recording file is managed.
Transfer to 6. The management PC 6 manages which file has been transferred from which guest room PC 2, and prevents a recording file created in another guest room PC 2 from being mixed when writing a recording file to the CD-R 4. The CD-R drive 3 is preferably a changer-type CD recorder (CD-R changer). The CD-R changer includes a plurality of trays for loading a plurality of CD-Rs, and transports the CD-R loaded on an arbitrary tray to a driving device that performs a data writing operation. Of course, software for controlling the CD-R changer is installed in the management PC 6. If a changer-type CD recorder is used, a changer tray is assigned to each guest room PC 2 and a CD-R prepared for a user of each guest room is loaded in the corresponding tray. When a recording file is transferred from a certain guest room PC 2 based on the correspondence between the tray and the guest room PC 2, the management PC 6 conveys the CD-R in the corresponding tray to the drive device and writes data. The network configuration in the centralized management system may be such that there are a plurality of CD-R drive devices and a plurality of management PCs for controlling each of the CD-R drive devices. Multiple CDs on the management PC
-R drive device may be connected. Of course, the management P is stored in the CD-R drive itself without going through the management PC.
A control function similar to C may be incorporated. It is also possible to connect a CD-R drive device to some guest room PCs. === Modification Example / Application Example === In the above embodiment, the provisional recording process is enabled by a recording instruction from the user. However, a configuration is also conceivable in which provisional recording is performed at every performance opportunity, and after completion of the performance, an instruction as to whether or not to dump the recorded content is input. The user may be allowed to select a file to be dumped from the temporarily recorded recording file. For example, for all the temporarily recorded files, a list of the song IDs and song names from which the files were generated is displayed on a display. Then, the file specified by the user may be written on the CD-R. In the above embodiment, the provisional recording operation is enabled / disabled based on the recording permission / prohibition information. However, at the time of the provisional recording, the recording permission / prohibition information is added to a recording file, temporarily stored, and the recording is prohibited. The recording file to which the above data is added may not be written to the CD-R. The configuration of the karaoke recording device is as follows:
The present invention is not limited to the configuration mainly including C, and may be a dedicated device or a form incorporated in a karaoke device. The recording permission / prohibition information may be provided on the karaoke apparatus side. That is, the recording permission / prohibition information is transferred to the guest room PC in a timely manner, and based on the transfer information, it is determined whether or not to perform the recording operation of the music piece. Recording of karaoke music may be permitted for a fee. If songs that can be recorded for free and songs that can be recorded for a fee, or songs that have different rates are mixed and provisionally recorded, the usage fee for the karaoke recording service will not be constant, and users will be confused. In such a case,
A configuration is conceivable in which information relating to copyright, such as a recording fee, is attached to the recording permission / prohibition information, and the copyright information is presented to the user before writing the recording file to the CD-R. The user can recognize the service fee and the like based on the presented information. Of course, it is also possible to adopt a usage mode in which only the paid recording file is instructed not to be written on the CD-R. As the copyright information, a table directly associated with the music ID may be separately prepared, and the copyright information may be indirectly associated with the recording availability information. Even when the recording permission information is managed on the karaoke recording apparatus side, the information source may be located on the karaoke apparatus side. For example, if the karaoke device is a performance terminal for communication karaoke, first, the karaoke device downloads the recording permission information from a karaoke data distribution source or the like, and transfers the updated recording permission information to the guest room PC. By doing so, it will be possible to quickly respond to updating of the recording availability information. Recently, some printers are capable of printing directly on the surface of a CD-R medium, and there are actually karaoke recorders incorporating this type of printer. Therefore, this printer may be incorporated in the configuration of the above-described embodiment to print appropriate information on the recorded file written on the CD-R. The print information may be the name of the written karaoke song or the recording date and time. In the case of the centralized management type described above, the ID of the recorded karaoke device (the cabin Number) is also conceivable. Printing copyright-related information, such as a copyright number, could also indicate the legitimacy of the recording. In the above embodiment, the karaoke apparatus is configured to input a mixed voice signal of karaoke accompaniment music and singing voice to the karaoke recording apparatus. However, the karaoke apparatus receives karaoke accompaniment music and microphone input. Some singing voices are output from individual voice output terminals. In correspondence with such a karaoke apparatus, the recording input interface may be provided with a plurality of audio input terminals for individually inputting audio signals of karaoke accompaniment music and singing voice input through the microphone. Thereby,
For example, it is possible to create a recording file in which either the karaoke accompaniment music or the singing voice is emphasized or muted by controlling the volume of the audio signal from one of the input terminals. As a matter of course, the portable recording medium in the karaoke recording apparatus of the present invention is a CD-recording medium.
Not only R but also an appropriate medium such as MD / DVD-RAM can be used. Of course, if the temporarily recorded file is D / A converted to analog data, an analog audio recording medium such as an audio cassette tape can be used. According to the karaoke recording apparatus of the present invention, the audio signals of the karaoke accompaniment music and the singing voice are temporarily stored as a recording file and then appropriately recorded on a portable recording medium in accordance with a user's dump request. I do. For this reason, it is possible to eliminate unnecessary recording on a portable recording medium when singing fails. In addition, since data writing to a portable recording medium is controlled based on the recording permission / prohibition information, it is possible to cope with a copyright problem when recording karaoke music. If the recorded files stored in the temporary storage device can be selected and displayed in a list, the user can select a desired file. If the fact that recording is not possible is displayed in advance based on the recording permission information, a valid reason for not recording is indicated, and consent of a user who desires recording can be obtained. By making it impossible to write a recording file of a predetermined number of songs or more in the temporary storage device, it is possible to prevent the capacity from being exceeded when a RAM or the like is used as the temporary storage device. In a store where a karaoke recording service fee is set for each medium, it is possible to set the number of recordable songs that is commensurate with the profit. If appropriate information is displayed based on the copyright information associated with the recording permission / prohibition information, for example, when a service fee is set for each song, or when a copyright fee differs for each song, etc. In addition, a fee for recording on a portable recording medium can be presented to the user so that the user is not confused. Further, if information based on the copyright information is displayed before being written to the portable recording medium, the cancellation can be performed. We can provide services according to the user's budget. With a configuration in which audio signals from a plurality of karaoke apparatuses are centrally managed and recorded, there is no need to provide a second recording control means for each karaoke apparatus, and the cost for the apparatuses can be reduced. In addition, the user does not need to mount a portable medium, and can concentrate on karaoke. If a portable recording medium that has been recorded at the front desk or the like is received at the time of settlement, convenience is improved.
