Public broadcasting system and method

Abstract

The invention belongs to the technical field of public broadcasting and computers, and provides a public broadcasting system and method. The public broadcasting system comprises a computer, broadcasting software and sound amplification equipment. The broadcasting software comprises a broadcasting control module and a multichannel control module. The broadcasting control module forms voice files according to demands. The multichannel control module reads the voice files and plays voice through the sound amplification equipment. According to the public broadcasting method, public broadcasting of the formed voice file sequences is directly realized through the sound amplification equipment via the broadcasting software installed on the computer. According to the system, the level and the structure of public broadcasting can be greatly simplified, and multiple sets of sound amplification equipment can be directly driven by one computer as for multi-partition broadcasting so that original work completed by combination of multiple sets of input control equipment, output control equipment and power amplification equipment can be realized, and wiring work of cables can be greatly reduced.
