Multiplex audio/video compression transmission server

The invention relates to a compressed transmission server of multipath audio and video, comprising an audio encoder/decoder, a video encoder/decoder, a digital signal processor (DSP), an ARM micro-processor, an Ethernet port, a serial port, a hard disk interface, a power circuit, an external microphone, a camera and a tripod head. Independent DSP chip and ARM chip are adopted to assemble a DSP+ ARM framework on a board; the tripod head is controlled by the ARM micro-processor through the serial port so as to realize the rotation and zoom of the camera, the audio and video analog signals are collected on-site in real time and are sent to the digital signal processor after an A/D conversion carried out by the audio and video decoder, and then a compressed encoding is carried out; the video signal is compressed by H.264 arithmetic, the audio signal is compressed by G.264 arithmetic, the code stream data is read by a HPI interface of the digital signal processor, and local hard disk storage and network transmission are carried out, thus realizing the real-time control of the on-site audio and video. The server has strong control and network function, good flexibility, extensibility and upgradeability.
