Motion JPEG Over IP – HD Video Encoder Subsystem

This Video Over IP Subsystem employs JPEG compression and RTP/UDP/IP encapsulation to enable the rapid development of complete motion JPEG video streaming products. Hardware reference designs and customization services complete the solution. 

The subsystem uses CAST’s JPEG-E-S, JPEG2RTP, and UDPIP IP cores. Flexible interfaces allow easy integration of video and network controllers; the cores’ AMBA® AXI4-Lite™ slave interfaces allow a host processor to access all control and status registers. An optional custom logic module allows standalone, processor-free operation and provides access to control and status registers via UDP packets. Video and stream data are transferred among the subsystem’s modules using AXI-Stream, making removing or adding modules straightforward.   

The produced stream can be decoded using Motion JPEG-compatible software viewers (e.g. VLC).

CAST IP subsystems runs on Xilinx’s Kintex-7 FPGA KC705 Evaluation Kit

A turnkey reference design for Xilinx’s Kintex-7 FPGA KC705 Evaluation Kit is readily available. The reference design integrates the MJPEGOIP-HDE Subsystem with Xilinx’s Ethernet MAC, and uses an HDMI receiver daughter-card for video input.

CAST can integrate the MJPEGOIP-HDE subsystem with your choice of video-in, and network controllers, and map it to Xilinx or Intel FPGA boards offering sufficient resources. We can also modify the subsystem to support multiple video channels, or different CAST video or image compression cores.
