In this embodiment, the target display device may encode the ultrasonic wave (similar to waveform adjustment, i.e., adjusting the sound waveform) before emitting the ultrasonic wave, so that the sound wave includes the information of the sound channel, and optionally, may also include the identification information (e.g., device number or serial number) of the target display device in the sound wave by encoding. The left channel ultrasonic wave and the right channel ultrasonic wave can be distinguished through coding, the left channel ultrasonic wave can be emitted by a left microphone of the target display device, and the right channel ultrasonic wave can be emitted by a right microphone of the target display device.
