Zusammenfassung:	The invention discloses a portable mobile audio/video teaching interaction device which comprises a mobile acquisition terminal, a monitoring management terminal and a remote client-side. The mobile acquisition terminal acquires videos through a camera, acquires audio through a microphone, utilizes a Hi3518E chip to compress codes and transmits the codes to the monitoring management terminal in a wireless mode. The monitoring management terminal uses Linux as an operating system, uses a Hi3520 embedded processor as a hardware platform, achieves H.264/AVC high-speed, high-efficiency compression, decompression and parameter optimization and is compatible with a variety of communication protocols RTP/RTSP and RTMP to perform media stream transmission. The remote client-side is used for achieving real-time analysis and playing of audio/video data. The portable mobile audio/video teaching interaction device developed by adopting an embedded method is already applied in practical teaching of a school, the transmiss
