Chen Anping · Jisuanji gongcheng yu sheji · 2007
The architecture of an audio multiplexer is presented,which is used in prison video surveillance system.The hardware design and software framework of audio multiplexer are discussed in detail.Each video signal coming into audio multiplexer is switched to the designated output,with audio signal switched synchronously.The transmission control of audio-visual signals among systems makes it possible to build a distributed and smart video surveillance system.
