JP 2005-77485 A

  By the way, each karaoke device performing communication duet singing is distinguished into a master side karaoke device and a slave side karaoke device, and a karaoke performance signal and a singing signal at the master side karaoke device are directed from the master side karaoke device to the slave side karaoke device. By transmitting only the singing signal at the slave side karaoke device from the slave side karaoke device to the master side karaoke device, the performance synchronization in each karaoke device is achieved, and a comfortable communication duet singing A system that can do this has been developed.

  In this master / slave system, the master side karaoke device uses the karaoke performance signal generated in the master side karaoke device, and the slave side karaoke device does not use the karaoke performance signal generated in the slave side karaoke device. The karaoke performance sound is output using the karaoke performance signal included in the received mixed sound signal.

  However, when such a master / slave system is adopted, the master side karaoke device can adjust the volume of the karaoke performance sound and the singing voice according to the user's desire. Since the volume of the karaoke performance sound and the singing voice adjusted in the master side karaoke apparatus is used, it may not be said that it always matches the user's desire.

  And in the slave side karaoke device, while performing the operation of adjusting the mixed voice signal (karaoke performance signal and master singing signal) and slave singing signal received from the master side karaoke device according to the user's desire, If the master side karaoke device performs an operation of adjusting the volume balance of the karaoke performance sound and the singing voice, the balance of the volume adjustment cannot be maintained.

  The present invention has been proposed in view of the above-described circumstances. In a karaoke system including a master side karaoke device and a slave side karaoke device that are communicably connected via a transmission line, each karaoke device has a desired volume level. It aims at outputting karaoke performance sound and singing voice.

  The karaoke system of the present invention has been proposed in view of the above-described circumstances, and has the following features. That is, the karaoke system of the present invention is a karaoke system composed of a master side karaoke device and a slave side karaoke device that are communicably connected by a transmission line, and the master side karaoke device and the slave side karaoke device are respectively: Means are provided. The master side karaoke apparatus includes karaoke performance signal output means, master singing signal output means, superimposed signal reception means, decoding means, mixed signal transmission means, and master mixing means. The slave-side karaoke apparatus includes slave singing signal output means, control signal acquisition means, superimposed signal transmission means, mixed signal reception means, and slave mixing means.

The decoding means is means for decoding the superimposed signal received by the superimposed signal receiving means and outputting a slave singing signal and a control signal. The mixing signal transmission means mixes the karaoke performance signal output from the karaoke performance signal output means and the master singing signal output from the master singing signal output means based on the control value of the control signal decoded by the decoding means. It is a means for generating a signal and transmitting the mixed signal to the slave side karaoke apparatus via the transmission line. The master mixing means mixes the karaoke performance signal output from the karaoke performance signal output means, the master singing signal output from the master singing signal output means, and the slave singing signal output from the decoding means at an arbitrary volume level. It is a means for outputting.

  The slave singing signal output means is means for outputting a slave singing signal. The control signal acquisition unit is a unit for acquiring a control signal in which a control value is defined. The superimposed signal transmitting means is for transmitting the superimposed signal obtained by superimposing the control signal acquired by the control signal acquiring means on the slave singing signal output by the slave singing signal output means to the master side karaoke apparatus via the transmission path. Means. The mixed signal receiving means is means for receiving the mixed signal transmitted by the mixed signal transmitting means via the transmission path. The slave mixing means is means for mixing and outputting the slave singing signal output by the slave singing signal output means and the mixed signal received by the mixed signal receiving means at an arbitrary volume level.

  In the karaoke system of the present invention, in addition to the above-described configuration, the slave-side karaoke apparatus can include at least three operators. Then, according to the output value of the first operator, the volume level of the mixed signal in the slave mixing means is controlled and the control value of the control signal is defined. Further, the control value of the control signal is defined according to the output value of the second operator. Furthermore, the volume level of the slave singing signal in the slave mixing means is controlled according to the output value of the third operator.

  In the karaoke system of the present invention having the above-described configuration, the karaoke apparatus is distinguished into a master karaoke apparatus and a slave karaoke apparatus in a karaoke apparatus connected by a transmission path. And in a slave side karaoke apparatus, a karaoke performance is performed using the karaoke performance signal of the master side karaoke apparatus transmitted from the master side karaoke apparatus via a transmission line, without using its own karaoke performance signal. That is, since the master side karaoke device generates a mixed signal by superimposing the karaoke performance signal and the master singing signal, by reproducing the mixed signal in the slave side karaoke device, the karaoke performance signal of the master side karaoke device And master singing signal can be played.

  On the other hand, the slave-side karaoke device generates a superimposed signal by superimposing the control signal on the slave singing signal, and transmits it to the master-side karaoke device via the transmission path. In the master side karaoke apparatus, the slave singing signal can be reproduced by decoding the superimposed signal. Furthermore, based on the control value of the control signal decoded from the superimposed signal, a mixed signal to be transmitted to the slave side karaoke apparatus is generated. That is, the volume of the mixed signal generated by the master side karaoke device is adjusted under the control of the control signal transmitted from the slave side karaoke device.

  In the karaoke system of the present invention, the karaoke devices connected by the transmission line are classified into a master karaoke device and a slave karaoke device, and the slave karaoke device reproduces a karaoke performance signal transmitted from the master karaoke device. To perform karaoke performance. This karaoke performance signal is mixed with the master singing signal to form a mixed signal. And the volume of the master singing signal in this mixed signal is adjusted based on the control value of the control signal transmitted from the slave side karaoke apparatus.

  Thus, the master side karaoke apparatus can independently adjust the volume of the karaoke performance sound and the singing voice according to the user's desire. On the other hand, the slave-side karaoke device can adjust the volume of the mixed signal obtained by mixing the karaoke performance signal and the master singing signal transmitted from the master-side karaoke device by transmitting a control signal to the master-side karaoke device. it can.

  Therefore, since both the master side karaoke device and the slave side karaoke device can output the karaoke performance sound and the singing sound of the desired volume, the users of both karaoke devices can fully enjoy the karaoke fun. You can enjoy it.
