Intelligent video co-processor for embedded DVR SoC

Most of embedded DVR systems have limited functions for intelligent video processing. In this paper, we propose architecture of an intelligent video processing system for embedded DVR systems. It consists of a conventional DVR host system and an intelligent video co-processor system. The co-processor system consists of an embedded processor and several primitive functional units for intelligent video processing, and can be connected to a host DVR system via an external bus interface. The proposed video processing system can perform video surveillance operations for four input video channels in real-time, and can provide a host DVR system with object information for further processing.
