<p>A multifunctional video/audio switching system is disclosed, which includes: a host and a line controller connected to the host electrically by a lead. Disposed on the host are video input and output ports and a video multiswitch unit; the video multiswitch unit is electrically connected to a Multipoint Control Unit (MCU); the video output port is electrically and bi-directionally connected to the MCU. Also disposed on the host are audio input and output ports and an audio multiswitch unit; the audio multiswitch unit is also electrically connected to the MCU. On the line controller are disposed a control microprocessor and a port to which it is bi-directionally connected; said port is electrically connected to the video output port of the host by a lead. The video input port also includes a set of ports electrically connected to a camera for inputting camera video signals over a lead. The system also includes a broadcast system comprised of a microphone and a MCU, a broadcast controller, an audio amplifier, and output loudspeakers all electrically connected in turn. The multifunctional video/audio system can satisfy the varied demands of different users.</p> |
