Audio transmission system and method

Abstract

The invention discloses an audio transmission system and method. In the audio transmission system, an antenna feeder subsystem is used for transmitting a plurality of paths of radio frequency source signals carrying target audio data to a plurality of paths of signal receiving subsystems; multiple paths of audio source signals obtained after the multiple paths of radio frequency source signals are demodulated by the multiple paths of signal receiving subsystems are transmitted to the signal source processing subsystem, and the multiple paths of audio source signals are transmitted to the monitoring and switching subsystem after being processed by the signal source processing subsystem; the monitoring and switching subsystem is used for transmitting the main path audio source signal to the transmitting subsystem as a target audio source signal; when the switching condition is met, the secondary audio source signal is used as a target audio source signal to be transmitted to the transmitting subsystem; at least one path of radio frequency signal obtained after the target audio source signal is modulated by the transmitting subsystem is transmitted to the antenna feeder subsystem; and the antenna feeder subsystem is used for transmitting at least one path of radio frequency signals to play target audio data. According to the embodiment of the invention, the transmission reliability of the audio data is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio technology, and in particular, to an audio transmission system and method. Background technique [0002] For audio data (such as listening content) that needs to be played uniformly in a certain jurisdiction, it can be played in two ways: wired broadcasting and wireless broadcasting. [0003] In the related art, the process of using wired broadcasting to play includes: using a wired broadcasting system to play an audio carrier (such as a tape) that stores audio data; signal, and then play the audio data; or directly play the audio data through the FM radio transmitting equipment. The process of broadcasting by means of wireless broadcasting includes: using the public FM broadcasting of the transmission center of the broadcasting station to uniformly broadcast the audio data in a certain jurisdiction. [0004] However, in the process of playing by wired broadcasting, the audio carrier, ...

Problems solved by technology

[0004] However, in the process of playing by wired broadcasting, the audio carrier, network equipment or FM broadcasting transmission equipment may suddenly fail, resulting in poor quality of audio data playback or interruption of audio data playback; in the process of playing by wireless broadcasting , In a certain jurisdiction, there may be new buildings that hinder the transmission of signals transmitted by public FM broadcasting. Some places in this jurisdiction receive weak or unable to receive transmission signals, resulting in the The quality of the audio data is poor or the playback of the audio data is interrupted. Therefore, the reliability of the transmission of the audio data in the related art is poor
