Abstract

The invention discloses an audio signal sending method. The audio signal sending method comprises the following steps: obtaining audio information of a first sound channel, audio information of a second sound channel, audio information of a third sound channel and audio information of a fourth sound channel; performing analogue-digital conversion of the obtained audio information of the first sound channel and the obtained audio information of the second sound channel so as to obtain first audio information, and performing analogue-digital conversion of the obtained audio information of the third sound channel and the obtained audio information of the fourth sound channel so as to obtain second audio information; performing coding operation of the first audio information and the second audio information so as to obtain information to be sent; and sending the information to be sent. The invention further discloses an audio signal sending device, an audio signal receiving method and device. According to the invention, the data information of the four sound channels is sent through one transmitter; therefore, mutual interference of transmitted signals due to the fact that the data information of the four sound channels is emitted by adopting two wireless transmission modules can be avoided; the number of the transmitters can be reduced; and the cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of audio signal processing, in particular to an audio signal sending and receiving method and device. Background technique [0002] In the home theater system, in order to make the connection of the whole system more convenient and keep the living room environment clean, the surround and bass function devices of the home theater system are connected wirelessly. [0003] In the wireless connection scheme of the existing home theater system, each pair of transmitting and receiving modules can only transmit data of two channels. Therefore, two pairs of transmitting and receiving modules are required to realize functions such as surround and bass in the home theater system. However, mutual interference occurs between the signals sent by the two wireless transmitting modules in this way, which further causes errors in the signals received by the receiving module and affects the audio effect of the home th...
