DETAILED DESCRIPTION OF THE INVENTION
==== Configuration of Karaoke Performance Apparatus ====
The karaoke performance apparatus according to the present invention has a communication function and can perform data communication with an appropriate portable device 100. The portable device 100 is a mobile phone, a PHS, a pager, an electronic notebook, a wristwatch, or the like, and can output a ring tone or an alarm sound as a ringing melody to a speaker with a built-in synthesizer or the like.
[0007]
A block circuit diagram of the karaoke performance apparatus is shown in FIG. The karaoke performance device shown in the figure is merely an example. The central control unit 11 is a computer that includes a CPU, a ROM, and a RAM inside, and controls the karaoke performance device 10 by supervising peripheral components. The hard disk device 12 stores karaoke data in which accompaniment music and lyrics images of karaoke music are encoded.
[0008]
When the central control unit 11 receives the music selection input from the remote control transmitter 30 or the operation panel 13 via the operation control unit 15, the central control unit 11 reads out the karaoke data of the requested music from the hard disk device 12. At the same time, the video CD changer 22 is controlled so as to reproduce a video CD on which an appropriate background video is recorded. Accompaniment music generation data such as MIDI data included in the karaoke data is sequentially transferred to the synthesizer 18 where accompaniment music is reproduced. The reproduced accompaniment music is combined with the singing signal from the microphone 21 by the mixing amplifier 19 and output from the speaker 20. On the other hand, the lyric image data is transferred to the display control unit 16 including a video RAM therein. The display control unit 16 expands the lyric image bitmap data in the video RAM and superimposes the lyric character string on the background video output from the video CD changer 22 while synchronizing the lyric character string with the progress of the accompaniment music. Output to.
[0009]
The central control unit 11 is connected to a data transfer interface 23 for data communication with a portable device. As this interface 23, for example, an interface conforming to an appropriate wireless communication standard such as IrDA is adopted.
[0010]
==== Function for audition and data transmission of ringing melody ====
<<< Ring melody part specified in MIDI data >>>
The karaoke data of the karaoke performance device 10 is diverted to supply the music generation data for the ringing melody to the portable device 100 with a communication function.
The data is a specific part in the MIDI data (performance data) of each music piece as shown in FIG. That is, one or a plurality of performance sections (melody 1 to 3) are specified as ringing melody candidates on the reproduction time axis (arrow direction in the drawing). This performance section is a section suitable for a ringing melody, which is the beginning of song, rust and characteristic melody part of each musical piece. In each performance section, in addition to the main melody part, a plurality of instrument parts constituting the harmony are specified. Data for specifying such performance sections and music parts is attached to the MIDI data of each music as auxiliary data. In accordance with the designation of the auxiliary data, partial MIDI data (ring melody part) corresponding to the ringing melody is extracted and supplied to the portable device 100. The storage capacity of this auxiliary data is extremely small compared to the entire MIDI data of each music piece.
[0011]
The MIDI data for generating this ringing melody will be specifically described. For example, as shown in the lower chart of FIG. 2, three types of melody 1 to 3 are specified in a certain music piece, and the start time (time t1, t3, t5) and end time ( Times t2, t4, t6) are designated. The synthesizer of the portable device 100 that receives the specified MIDI data is often composed of a relatively simple one-chip IC, and can be applied to all of various MIDI channels like the high-class synthesizer 18 of a karaoke performance device. Correspondingly, ringing melodies cannot be created. For this reason, in the melody 1 to 3 in each performance section, all the MIDI channels originally designated as accompaniment music generation data are not specified for generating a ringing melody. As shown in the lower chart of FIG. 2, each melody 1 to 3 designates a limited number of MIDI channels.
[0012]
Even if the MIDI channel is specified in such a limited manner, depending on the portable device 100 of the supply partner, it may not be possible to support all of the specified MIDI channels. In preparation for such a case, priorities are assigned to MIDI channels, and MIDI channel numbers having higher priorities are extracted and supplied in accordance with the sound source specifications of the portable device 100. Note that the MIDI data of the melody portion that is simultaneously generated on the same MIDI channel to form a chord is also supplied after being reduced to data that can be generated simultaneously according to the sound source specifications of the other party's portable device.
[0013]
<<<< Operation of Audition and Supply of Ringing Melody >>>>
As shown in the flowchart of FIG. 3, when an operation input for listening to a ringing melody is received through the remote control transmitter 30 or the operation panel 13, an operation input for designating a music is waited (S10 → S20). At this time, a screen for prompting an operation input for music designation is displayed on the display 17 and waits. When the music is designated, the communication operation with the portable device 100 is started. If the communication is not established, a screen prompting the mobile device 100 to set the melody reception mode is displayed on the display 17 (S30 → S40). When the communication is established, the portable device 100 acquires a sound source specification for generating a sound signal of a ringing melody (S50). Then, each ringing melody of the music designated in S20 is sequentially played according to the obtained sound source specifications (S60).
[0014]
When a series of performance operations are completed, a menu screen for determining the melody selection is displayed, and an operation input for selecting a melody to be loaded into the mobile device 100 from a plurality of (or in some cases) ringing melody played is waited for (S70). An example of the menu screen is shown in FIG. At this time, a selection input for re-listening the ringing melody is also accepted, and if there is this, the performance is performed again. When there is a decision input of a ringing melody to be supplied to the mobile device 100, the format of the data format available here is recognized from the mobile device 100 in communication (S70 → S80). Then, the MIDI data of the corresponding ringing melody according to the sound source specification of the mobile device 100 is converted into the data format and transmitted to the mobile device 100 (S90). The portable device 100 receives the transmitted MIDI data, stores it in a built-in storage unit, and uses it as a ringing melody.
[0015]
【The invention's effect】
Karaoke performance equipment can be used as a data source for ringing melodies of mobile devices with communication functions. By using a huge amount of karaoke data stored in a karaoke performance device, it is possible to supply music generation data for ringing melody to mobile devices with communication functions. For this reason, a favorite melody can be arbitrarily selected from a huge amount of music. And it is not necessary to provide a separate music generation database for ringing melodies.
[0016]
Prior to supplying the music generation data for the ringing melody, the performance according to the performance control format of the portable device is performed, so that the actual ringing state of the melody in the portable device can be confirmed in advance.
Furthermore, when the music generation data for the ringing melody is supplied, the data format format of the other party's mobile device is acquired after communication, so that it can be supplied to mobile devices of various specifications as needed. Then, since the data is supplied after being converted into the data format of the counterpart mobile device, the mobile device does not have to bear the format conversion processing.
