Abstract: Aim at problems like poor signal, vulnerable to environmental interference, low system integration degree and cannot display site rescue information on the spot exist in current underground rescue video, a kind of embedded video signal processing system suitable for underground rescue communication was put forward. The system mainly consists of two parts: the underground video capture terminal and surface rescue command terminal. H.264 standard compression done on video data by using the own encoder MFC of S3C6410 and adopt Linux as software develop platform in the underground video capture terminal system. On the other hand, video decoding, network transmission and development of application program realized for surface rescue command terminal system in VS2005 development environment, and according to the characteristics of the mine rescue environment, an optimization about the open source for H.264 decoding algorithm is made. This system has accomplished rescue site video processing, improved the equipment integration level and video picture clarity, and realized the visualization of underground rescue.
