The playing section 107 has a built-in MIDI sound source and converts music data received from the playback control section 103 into music signals in accordance with playback timing information from the playback time adjustment section 106. As in the case of a general MIDI sound source, a sound source whose pitch can be changed or its reproduction speed is variable is used.

FIG. 1B is a block diagram showing the configuration of the model singing signal transmitting apparatus according to the first embodiment of the present invention. In FIG. 1B, reference numeral 110 denotes an utterance data storage unit;
111 is a transmission control unit, 112 is an audio signal reproduction unit, 113
Denotes a transmission processing unit, and 114 denotes an antenna (same function as the antenna 104).

The utterance data storage unit 110 is a storage device for storing utterance data for generating an audio signal. Specifically, using the request number of the song as a key, the timing information of the beat is stored in addition to the singing voice data of the singer recorded by PCM. As described above, the beat timing information of the utterance data has the same information amount as the beat timing information extracted from the performance data.

The transmission control unit 111 reads out the utterance data of the song having the request number received from the portable karaoke terminal from the utterance data storage unit 110, and outputs the audio data, specifically, P
The singing voice data of the singer recorded in the CM is reproduced by the audio signal reproducing unit 11.
Output to 2. Also, it extracts the timing information of the time signature from the utterance data and outputs an audio signal transmission instruction to the transmission processing unit 113 in conjunction with the extracted timing information.

The audio signal reproducing unit 112 is a sound source that converts and reproduces PCM-recorded data into an audio signal that can be output by a speaker or the like. A sound source whose pitch is changed and whose playback speed is variable is used.

The transmission processing unit 113 includes an audio signal reproducing unit 112
This is a modulation circuit that modulates and outputs the audio signal output at. Based on the time signature information of the utterance data output by the transmission control unit 111, the time signature is spectrally spread and modulated in accordance with the time series of the audio signal to be transmitted. In addition, a demodulation circuit and a processing circuit for receiving and demodulating a modulation signal from the portable karaoke terminal and extracting control information are provided.

Next, the operation of the portable karaoke terminal and the model singing signal transmitting device according to the first embodiment of the present invention will be described.

The user inputs the request number of the music using the numeric keypad of the operation unit 102 with reference to the karaoke table of contents and the like, and completes the reservation with the "reservation button" as in the case of general karaoke. The operation unit 102 communicates with the reproduction control unit 103 in order to check whether a song is being reproduced on the portable karaoke terminal. If the reproduction has been completed, a music request number is taken out of the reservation queue and output to the reproduction control unit 103. If the reproduction is in progress, the operation unit 102 outputs the music request number until the notification of the reproduction completion is received.

Playback control unit 1 receiving the request number of the music
03 reads out the performance data of the music from the performance data storage unit 101. The MIDI data section of the performance data is output to the performance section 107 as music data. Also, MI
Tempo information, key information and beat timing are extracted from the DI data and output as music timing information.

In the initial state of the apparatus, the model singing function is OFF.
It has become. The reproduction time adjustment unit 106 instructs the performance unit 107 to immediately reproduce the MIDI data. Upon receiving the reproduction instruction, the performance unit 107 converts the MIDI data into a music signal. The singing signal including the model singing is not output from the communication processing unit 105. Therefore, the music signal is guided to the speaker 109 without being particularly mixed by the mixer 108, and the general so-called "MID"
"I Karaoke" has been realized.

Here, when the "model singing button" is pressed on the operation unit 102, the model singing function is turned on. The fact that the model singing function has been turned on is transmitted to the reproduction control unit 103, and further, the reproduction time adjustment unit 106 and the communication processing unit 1
It is told to 05. Further, the reproduction control unit 103 reads the current reproduction position of the music data (hereinafter, referred to as time A) from 106 in addition to the request number of the music,
The communication processing unit 105 further includes the request number of the song.
Tell The time A is transmitted to the communication processing unit 105 in order to absorb a difference in reproduction time between the music signal and the singing signal when mixing is performed by the mixer 108 later.

When the model singing function is turned on, the communication processing unit 105 sends the request number of the song to the model singing signal transmitting device. At this time, in order to absorb a difference in the reproduction time between the music signal and the singing signal at the time of mixing by the mixer 108, the reproduction of the music data at the time when the reproduction data is read out by the reproduction control unit 103 in addition to the request number of the music. A control signal including information on the position (that is, time A) and the time stamp at the time of transmitting the modulated signal (hereinafter, referred to as time B) is modulated, and transmitted from the antenna 104 to the model singing signal transmitting apparatus.

The model singing signal transmitting device receives the modulated signal via the antenna 114. The received modulation signal is sent to the transmission processing unit 1
The demodulated data is demodulated at step 13, and the request number of the music is extracted. Further, the transmission processing unit 113 compares the received time stamp (that is, time B) with its own clock (hereinafter, referred to as time C), and compares the time (hereinafter, referred to as time) related to communication between the portable karaoke terminal and the model singing signal transmission device. A time D) is calculated and transmitted to the transmission control unit 111 together with the request number of the music and the information on the reproduction position (that is, time A) of the music data at the time of reading by the reproduction control unit 103.

The transmission control unit 111 reads the utterance data of the received request number of the music from the utterance data storage unit 110, extracts the PCM-recorded audio data, and outputs it to the audio signal reproduction unit 112. At the same time, time signature information of the utterance data is transmitted to the transmission processing unit 113. Further, the transmission control unit 111 provides the audio signal reproduction unit 112 with a time from when the transmission control unit 111 receives the request number of the music until the processing up to this point is completed (hereinafter, referred to as time E).
And the time required for communication with the model singing signal transmitting device (ie, time D) is a round-trip time, that is, twice, and the reproduction position of the music data at the time of reading by the reproduction control unit 103 (ie, time A). Is instructed to convert and reproduce the audio data into an audio signal from the time position (hereinafter, referred to as time F) to which is added. Similarly, the transmission control unit 111 instructs the transmission processing unit 113 to superimpose the beat timing using the time F as the reproduction start time.

The audio signal reproducing section 112 converts and reproduces the audio data from the reproduction start time (ie, time F) and outputs the audio signal to the transmission processing section 113. Upon receiving the audio signal, the transmission processing unit 113 spreads and modulates the time signature of the time signature, and outputs the result from the antenna 114 to the portable karaoke terminal.

The portable karaoke terminal receives the modulated signal at antenna 104. The received modulated signal is transmitted to the communication processing unit 105
The sampled singing sound demodulated and modulated as an audio signal is extracted as a singing signal and output to the mixer 108, and the beat timing is extracted as singing timing information and output to the reproduction time adjustment unit 106.

The reproduction time adjustment unit 106 detects the difference between the singing timing information and the music timing information, calculates the time differential, and outputs the result to the playing unit 107 as reproduction timing information. In other words, when the singing timing information is ahead of the music timing information, the performance unit 107 is instructed to accelerate the conversion reproduction tempo from the music data to the music signal. Conversely, when the singing timing information is behind the music timing information, the performance unit 10 converts the music data into a music signal so as to delay the playback tempo.
7 will be instructed.

The rough time correction has already been performed by adjusting the timing of conversion and reproduction by the audio signal reproduction unit 112. By performing the above operation, the reproduction time adjustment unit 106 can perform fine timing adjustment. Is performed.

The playing section 107 converts and reproduces music data in accordance with the reproduction timing information and outputs a music signal. The mixer 108 superimposes and synthesizes the music signal and the singing signal output from the communication processing unit 15 and outputs the resultant signal to the speaker 109. Therefore, the model singing sound is output from the speaker 109 in a state of being superimposed on normal karaoke.

In the above, the model singing function is turned off during the reproduction of the music.
Although the description has been given of the case where the device is switched from to ON, the operation of the apparatus is the same when the request number of the music is output to the reproduction control unit 103 when the model singing function is ON. Regarding the delay from receiving the request due to the communication time between the mobile karaoke terminal and the model singing signal transmission device until the singing signal is transmitted, the karaoke user usually does not have to start singing to the karaoke song immediately Since there is a blank period, it can be ignored.

If the performance data of the tune reserved by the operation unit 102 is not stored in the performance data storage unit 101, the karaoke music is downloaded in the same manner as a general communication karaoke (the karaoke tune is stored in the terminal of the receiver). In a format in which the performance data is played back offline), the communication processing unit 305 communicates with the performance data management center, and the performance data storage unit 101
After the performance data is stored, the karaoke output may be started. If a sufficient communication speed for the performance can be secured with the center, the performance data is stored in the performance data storage unit 101 in a stream format (a format in which the recipient plays the karaoke music online at the recipient's terminal). The reproduction control unit may analyze the performance data and output the music data while storing the data. The performance data storage unit 101
It is also possible to deal with this by making the removable type and replacing it with the medium containing the music to be played.

The performance data is assumed to be equivalent to the MIDI format.
It is also possible to prepare data to which control information specified in the DI format is added and store it in the performance data storage unit. In this case, the performance unit 107 converts the sampled music into a sound source that converts the sampled music into a music signal, so that output to the mixer 108 and the speaker 109 is not hindered.

In order to provide a portable karaoke terminal capable of viewing only the model voice, the operation unit 102 is further provided with a toggle type "model voice only button". In step 108, only the singing signal is output, which can be easily handled.

It should be noted that a general MIDI sound source is relatively easy to change the pitch and the tempo. Also, P
A pitch conversion technique for a CM-recorded voice is also common. Also in the present embodiment, the operation unit 102 is provided with a button for changing a pitch or a tempo, and when the performance unit 107 and the audio signal reproduction unit 112 convert and reproduce performance data and audio data, the pitch and the tempo are changed. For example, it is possible to change the pitch or the tempo of the karaoke with the model singing sound output from the speaker.

In the present embodiment, since the input modulation signal is a wireless signal, it is a wireless modulation / demodulation circuit. Further, the communication processing unit 205 extracts a synchronization pulse spectrally spread in the modulated signal and outputs the synchronization pulse as singing timing information. The synchronization pulse is transmitted after being spectrally spread in the modulation signal based on the pulse output from the pulse generation unit 215 provided in the model singing signal transmission device.

The reproduction time adjustment unit 206 measures the time fluctuation of the singing timing information. In order for the mixer 108 to synchronize the singing signal and the music signal, reproduction timing information is output to the playing section 107 in accordance with the magnitude of the fluctuation.

Since the other configuration of the model singing signal transmitting device according to the second embodiment is the same as that of the model singing signal transmitting device according to the first embodiment, the other components are denoted by the same reference numerals. And the description is omitted.

The utterance data storage unit 210 is a storage device for storing utterance data for generating an audio signal. Specifically, using the request number of the song as a key, the timing information of the beat is stored in addition to the singing voice data of the singer recorded by PCM. Unlike the utterance data storage unit 110, in particular, the utterance data storage unit 110 may not have the time signature information.

The transmission control section 211 reads out the utterance data of the music of the request number received from the portable karaoke terminal from the utterance data storage section 210 and outputs the audio data to the audio signal reproduction section 112.

Other configurations of the model singing signal transmission device according to the second embodiment are the same as those of the model singing signal transmission device according to the second embodiment, and thus the same reference numerals are given to the other components. And the description is omitted.

The sending control unit 311 reads out the utterance data of the music of the request number received from the portable karaoke terminal from the utterance data storage unit 210, and outputs the audio data to the audio packet generation unit 312.

The voice packet generation unit 312 is
The audio data transmitted from the packet 11 is packetized. The generated packet waits for a transmission request from the transmission processing unit 313 and outputs the packet to the transmission processing unit 313.

The transmission processing unit 313 includes the voice packet generation unit 1
A modulation circuit that modulates and outputs the packet output at 12. In order to transmit and receive control information, a demodulation circuit and a processing circuit are additionally provided.

Next, the operation of the portable karaoke terminal and the model singing signal transmitting device according to the third embodiment of the present invention will be described. The third embodiment differs from the second embodiment in that:
The difference is that the transmission and reception of the singing signal is performed in packets. Accordingly, the singing signal and the music signal are synchronized only on the portable karaoke terminal.

The reproduction control unit 303 which has received the output of the music request number from the operation unit 102 sends the request number to the transmission control unit 311 through the communication processing unit 305 and the transmission processing unit 313. The transmission control unit 311 reads out from the pronunciation data storage unit 210, extracts PCM-recorded voice data, and outputs it to the voice packet generation unit 312. The audio packet generation unit 312 divides the audio data into packets and waits for a packet output request from the transmission processing unit 313.

The transmission processing unit 313 inputs packets from 312 until control information indicating that packet transmission is stopped is transmitted from the communication processing unit 305, and sequentially sends the packets to the portable karaoke terminal. The communication processing unit 305 reconstructs the transmitted packet, outputs the singing data to the singing signal reproducing unit 316, and issues a packet transmission stop request when the arriving packet amount is about to exceed the processable packet amount. The data is transmitted to the transmission processing unit 313.

On the other hand, the reproduction time adjusting section 306 refers to the singing timing information, confirms that singing data of 10 seconds or more has been sent to the singing signal reproducing section 316, and sends the music data to the playing section 107. Is converted into a music signal, and at the same time, the singing signal reproducing unit 316 is instructed to convert the singing data into the singing signal. Mixer 10
Reference numeral 8 denotes a speaker 1 by superimposing and synthesizing the music signal and the singing signal.
09 is output. Therefore, the model singing sound is output from the speaker 109 in a state of being superimposed on normal karaoke.

According to the third embodiment of the present invention, since the model singing signal transmitting device is packetized from the model singing signal transmitting device to the portable karaoke terminal and transmits the voice data, the transmission delay between the devices can be suppressed, and the singing signal can be suppressed. And music signals can be more easily synchronized.

According to the embodiment of the present invention, the music signal is converted and reproduced by the performance unit 107 based on the performance data stored in the performance data storage unit 101 provided in the portable karaoke terminal, and the karaoke reproduction is performed. The vocal data storage unit 110 and the vocal data storage unit 210 included in the singing signal transmitting device
The mixer 108 superimposes and outputs a singing signal generated based on the utterance data stored in the karaoke unit, thereby maximizing the sound quality of the karaoke sound source, and karaoke with a model singing sound in an environment where communication bandwidth is restricted. Can be obtained.

Also, paying attention to the characteristic that the karaoke data is music data, the pulse generation unit 21 is controlled by a control method using beat timing, or is not dependent on data.
By providing the karaoke apparatus 5, it is possible to obtain a karaoke with a model singing sound in which the reproduction timing difference between the music signal and the singing signal due to mobile communication or the like is absorbed and matched exactly.
