| Abstract: | An embedded video capture and encoding system is designed based on two independent DSP and ARM for real-time video communication over network. The video sequences are captured and encoded in MJPEG2000, and then the data packets are transmitted to user. The hardware principle and software principle of the system are described. In particular, the scheme of how to design the interface between DSP and ARM effectively is described. The system is novel and flexible. |
