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).

• Complete subsystem streams 1080p video with lower latency, less power consumption, and fewer silicon resources than hardware video codecs or software compression.
• Motion-JPEG Video Compression
  • Ultra-low, sub-frame latency capable
  • No frame buffering, eliminates the need for external DRAM
  • Quality equivalent to video compression for compression ratios up to 20:1 
• RTP encapsulation according to RFC 2435 
  • Compressed stream decodable by compliant software decoders/viewers such as VLC 
• Host interface via AXi4-Lite or processor-free UDP-controlled operation
• AXI4-ST bus for Video & Stream
• Customization Options
  • Integration with Video-In Controllers (e.g., DVI, HDMI, MIPI-CSI, or SDI)
  • Integration with IP-based MAC controllers (e.g., Ethernet or 802.11 WiFi)
  • Multiple video channels, different video preprocessing modules, or different compression algorithms
