Abstract
In a system in which a plurality of speakers are connected to an acoustic reproduction apparatus which reproduces an acoustic signal input from an external sound source by transmitting the acoustic signal to each speaker, the acoustic reproduction apparatus transmits a control signal by superimposing the control signal on an acoustic signal to be transmit to each speaker. Each speaker generates a predetermined response signal in accordance with the transmitted control signal. When reproducing the acoustic signal, acoustic control is executed in accordance with the generated response signal.
Claims14
A data relay apparatus for relaying a data signal input from an external sound source by transmitting the data signal to a plurality of speakers, comprising:
- a transmission unit that transmits a control signal by superimposing the control signal on a data signal to be transmitted to the plurality of speakers;
- a pick-up unit that picks up response signals generated by the plurality of speakers in accordance with the control signal transmitted by the transmission unit;
- and
- an execution unit that executes control when relaying the data signal, in accordance with the response signals picked up by the pick-up unit.
A control method of a data relay apparatus which relays a data signal input from an external sound source by transmitting the data signal to a plurality of speakers, comprising:
- transmitting a control signal by superimposing the control signal on a data signal to be transmitted to the plurality of speakers;
- picking up response signals generated by the plurality of speakers in accordance with the control signal transmitted in the transmitting step;
- and
- executing control when relaying the data signal, in accordance with the response signals picked up in the picking up step.
