Nuvation's IP Camera ‘PoE’ DM357 Reference Design is a compact, PoE-enabled
implementation of a D1, full color, WDR, IP Camera based on Pixim’s Orca chipset and TI DaVinci™ DM357 Digital Media SoC with ARM926 and Fixed-Function Video Coprocessor. The reference design is targeted for high-quality IP Box Cameras which can be taken to production quickly. Derivative products can also be developed from the reference design.

Hardware Architecture

System Architecture

At the front of the IP camera, behind the lens, sits a Pixim ORCA CMOS sensor and processor, which captures and processes images and sends out BT.656 digital video to a TI DaVinci™ DM357 processor. The DaVinci™ processor encodes the stream and transmits the compressed video over Ethernet.

Within the DaVinci™, the incoming BT.656 video stream is processed by the Fixed-Function Video Coprocessor. The Coprocessor encodes it with the chosen video codec and passes the data back to the ARM. The ARM then packetizes the data using the RTP/RTSP over UDP/TCP protocol and sends the stream to the Ethernet PHY chip for transmission over the network.

A web server running on the ARM within the DaVinci™ allows users on the network to configure IP Camera settings through a browser utility. Setting changes are sent over the UART interface to the PIXIM processor board using a proprietary protocol.
