We accept from. 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 6 for supplying a 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 corresponding to the music ID specified by the user is transferred to the synthesizer to generate karaoke accompaniment music. In addition, the lyrics rendering data is processed to develop the lyrics image into a bit map in the video RAM, which is converted into a video signal and displayed on a display. The user's singing voice input through the microphone is mixed with the karaoke accompaniment music, and the voice signal is acoustically output from the speaker. It also has two audio output terminals for individually outputting an audio signal of the karaoke accompaniment music and an audio signal of the singing voice input to the microphone. The audio output terminals of each system and the recording input of the karaoke recording device are provided. The audio input terminal of the corresponding system in the interface is connected. === Overview of Karaoke Recording Function === The karaoke recording apparatus of the present invention detects whether a singing voice has been input together with karaoke accompaniment music, and indicates that the singing voice has not been recorded. And output as appropriate. As a result, it is possible to provide information for determining how to deal with the copyright, such as whether the karaoke store charges the user with the copyright included in the karaoke recording service fee. Further, it is possible to flexibly cope with a karaoke song for which recording is prohibited or a karaoke song for which recording is conditionally permitted. In the present embodiment, a recording permission / non-permission information table in which a music ID is associated with recording permission / non-permission and recording conditions for permitting recording with conditions as recording permission / prohibition information is stored in the hard disk device 12 in advance and prepared. And the control information interface 13
Song ID of the karaoke accompaniment music to be recorded via
Is received, the ID is referred to the table, and the recording control is appropriately performed based on the recording enable / disable information associated with the ID, or the input state of the singing voice during the performance of the karaoke accompaniment music and the record enable / disable information. And various information output controls. FIG. 3 is a schematic diagram showing how to deal with recording control, information output, and the like in accordance with a combination of the type of the recording permission / inhibition information and the input state of the singing voice. In this embodiment, three types of recording permission information are set: unconditionally permitted, unconditionally prohibited, and conditionally permitted. "Conditionally permitted" means that only karaoke accompaniment music is transferred to the CD-R. Recording is prohibited. Hereinafter, recording control and the like according to various types of the recording permission information will be described. === When Recording Is Unconditionally Forbidden === When the user operates the guest room PC 2 and inputs that the karaoke recording service is to be used, the central control unit 11 starts karaoke after the input. For the karaoke music played by the device 6, firstly, a music ID is obtained through the control information interface 13, and the ID is referred to a recording availability table. At this point, no control relating to the recording is performed for the music whose recording is unconditionally prohibited. In addition, the fact is displayed on the display to obtain the user's consent. === When Recording is Unconditionally Allowed === The central control unit 11 refers to the recording permission / prohibition information table for the ID of the karaoke song that the user is trying to record, and the recording is unconditionally performed. When it is recognized that the recording is permitted, an appropriate area in the RAM is secured as a recording data storage area. When the start of the performance of the karaoke music is detected, for example, when the performance start timing data is received from the karaoke apparatus, the PC
M data is stored in this area. Also, it monitors the signal strength from the audio level detector. When the music performance end signal is received from the karaoke device 6 or the like, the P
When the storage of the CM data is stopped, a screen asking the user whether to save the PCM data is displayed on the display 2.
Display at 0. If there is a storage instruction (dump request), a stored file (such as a WAV file) of an appropriate name, such as a music ID, is created in the stored PCM data, and the file is written to a CD-R according to the music CD standard. Record in the same format. Further, depending on whether the audio level detection unit detects a signal of a predetermined level or higher during the performance of one music piece or not, for example, "singing voice is present"
Or, create print data including different information (singing detection information) such as “no singing voice” and supply it to the printer.
Print on the label side of CD-R. The recording file name, karaoke song name, recording date and time are also printed.
The karaoke store can respond appropriately, such as charging a service fee including a copyright fee in accordance with the singing detection information printed on the CD-R. It is also possible to write recording files for a plurality of songs on a CD-R,
In that case, the presence or absence of a singing voice should be added for each recording file name. By doing so, it would be possible to calculate the karaoke recording service fee for each song. If an instruction not to save the recorded contents is input within a fixed time after the performance or during the performance, the PCM data stored in the RAM is deleted. Alternatively, the previous data is overwritten with PCM data input at the next performance opportunity. === Case where Recording is Conditionally Permitted === The central control unit 11 determines that the recording permission is associated with the karaoke music to be recorded according to the recording permission / non-permission information table. While the PCM data from the interface 14 is stored in the RAM, the signal strength from the audio level detector is monitored. At the end of the music performance, if the voice level detector recognizes that a signal of a predetermined level or higher has not been detected, the stored PCM data is deleted and C
The display 20 indicates that recording on the DR is not possible. On the other hand, when a signal of a predetermined level or more is detected, a screen for inquiring the user whether to save the PCM data is displayed on the display 20. Is created, and the file is recorded on a CD-R. In addition, singing detection information such as “singing voice present” is printed on the CD-R. This ensures that the recorded CD-R has been recorded according to regular procedures. === 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 and a printer is attached to each karaoke apparatus, a large amount of capital investment is required for a store having many karaoke apparatuses. 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. 4 is a schematic block diagram showing an embodiment of the karaoke recording apparatus of the centralized management system. A guest room PC 2b is individually connected to each karaoke device 6. The guest room PC 2b executes the process up to the recording file creation process in the guest room PC 2 of the above embodiment. Each guest room PC 2b is connected by a LAN to a computer (management PC) 7 having the CD-R drive 3 attached thereto. The guest room PC 2b creates a recording file for each karaoke device 6. When the guest in each guest room performs a dump request operation of the recorded file, the recorded file is managed.
Transfer to C7. The management PC 7 manages which file has been transferred from which room PC 2 and the CD-R 4
When a recording file is written into the PC, a recording file created by another guest room PC 2 is not mixed. Also,
Receive print information as supplementary information of each recording file,
The print information corresponding to the recording file written on the CD-R to be printed is printed. It is desirable that the CD-R driving device 3 is 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 this CD-R changer is implemented in the management PC 7. 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. Management PC7 is tray and guest room PC2b
When a recording file is transferred from a certain guest room PC 2b based on the correspondence between
R is transported to the driving device and data is written. 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. === Supplement / Modification / Application Example === In the above embodiment, the supplementary information of the recording file was printed out. Of course, the present invention is not limited to the print output, and it is also possible to display and output on the display whether or not the karaoke store or the user has the singing voice on the CD-R. Also, it is possible to print on a slip or the like without directly printing on the CD-R itself. With the above-mentioned centralized management system, the karaoke shop side can surely confirm the content recorded on the CD-R simply by displaying it on the display of the management PC. As described above, any output form of the detection result of the singing voice during the performance of the karaoke music to be recorded may be used as long as it can be confirmed that the detection result is associated with the recording file written on the CD-R. In the above-described embodiment, no recording operation is performed for a music piece whose recording is unconditionally prohibited. However, a configuration may be adopted in which PCM data is stored in the RAM for the time being and a dump request is not accepted. Also, a CD-R with singing and a CD without singing
If the selling price is different from that of -R, when the PCM data has been stored, the price is displayed and the user is asked to confirm it, and if there is a dump request, the recording file is written to CD-R. The writing configuration may be adopted. Thereby, it is possible to avoid a situation in which the user creates a CD-R without singing without knowing the fee system and pays an unwilling fee. The recording permission / prohibition information may include a license number of copyright, a copyright fee for recording, and the like. For example, if the license number is printed on a CD-R, the validity of the CD-R itself is guaranteed. Further, when the karaoke recording service fee is different depending on the presence or absence of the singing voice, the user can recognize the appropriateness of the fee by displaying or printing a copyright fee or the like. As a matter of course, as a portable recording medium in the karaoke recording apparatus of the present invention, CD-
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, it is possible to output appropriate information depending on whether or not a singing voice is recorded on a portable recording medium. Therefore, the karaoke store side can charge the user for the usage fee of the karaoke recording device according to whether or not the singing voice is recorded. Therefore, the karaoke accompaniment music is prevented from being illegally copied. In addition, when karaoke accompaniment music is recorded with singing voices, the user can use the karaoke recording device at an appropriate fee, such as reducing the usage fee. By printing accompanying information relating to the result of singing voice detection, such as permission of copyright and singing voice being recorded on the portable recording medium, the recorded portable recording medium becomes copyright. It can clearly indicate that it is a legitimate music medium based on it. Also, the karaoke store can easily check the recorded contents of the portable recording medium. By performing the recording control based on the recording availability information for each karaoke song and the presence / absence of singing voice input, even if the recording conditions are different for each karaoke song or complicated recording conditions are set. Can deal flexibly.
