Transmission device, reception device, and control method thereof

Abstract

Disclosed are a transmission device, a reception device, and a control method. The transmission device comprises: a communication interface comprising circuitry and at least one processor, comprising processing circuitry, wherein at least one processor, individually and/or collectively, is configured to: from among audio signals of a plurality of channels including a left channel, a sub-left channel, a right channel, a sub-right channel, and a woofer channel, separates the audio signals of the sub-left channel and the sub-right channel into a high-pass audio signal and a low-pass audio signal, respectively, on the basis of a frequency band; mixes the high-pass audio signal of the sub-left channel and the high-pass audio signal of the sub-right channel with the audio signal of the woofer channel; mixes the low-pass audio signal of the sub-left channel with the audio signal of the left channel; mixes the low-pass audio signal of the sub-right channel with the audio signal of the right channel; and control the communication interface to transmit the audio signals of the mixed woofer channel, the mixed left channel, and the mixed right channel to the reception device.
