Pairing method based on two-way communication, and video-audio entertainment system

A pairing method, based on two-way communication and applicable to a microphone, the pairing method comprising:

• receiving frequency information of a target frequency sent by a receiver, wherein the target frequency is a frequency at which the receiver has least interference within a range of the receiver or is a frequency stored in the receiver;
• switching a working frequency of the microphone to the target frequency, and generating pairing information;
• and
• sending the pairing information through the target frequency to the receiver, wherein the receiver is configured to determine, according to the pairing information, whether to pair and connect with the microphone, wherein the pairing information comprises identity information of the microphone.

A video-audio entertainment system, comprising a processor, a communication interface, a memory, and a communication bus, wherein

• the processor, the communication interface, and the memory communicate with each other through the communication bus;
• the memory is configured to store a computer program;
• and
• the processor is configured to execute the computer program to perform operations comprising:
• determining, by a receiver, a target frequency, wherein the target frequency is a frequency at which the receiver has least interference within a range of the receiver or is a frequency stored in the receiver;
• sending, by the receiver, frequency information of the target frequency to a microphone;
• receiving, by the receiver, pairing information from the microphone, wherein the pairing information comprises identity information of the microphone;
• determining, by the receiver, according to the pairing information, whether the identity information of the microphone matches identity information stored in the receiver;
• and
• in response to determining that the identity information of the microphone matches the identity information stored in the receiver, switching, by the receiver, a working frequency of the receiver to the target frequency to pair and connect with the microphone.
