Abstract: Depending on the analysis of the networking trend and the real-time demand of video monitoring system, DSP TMS320C6416 and ARM micro-controller are used to implement an embedded video encoder with industrial Ethernet interface. This paper presents the principle of system structure and hardware design, while finishes DSP encoding algorithm and NAL interface for RTP/UDP/IP. The test shows that the platform can support transmitting video flows in a high quality via Ethernet networks.
