MJPEGOIP-HDE
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).
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.
| FPGA Family / Platform | Video-In | Stream Out | 3rd Party Cores | Video Formats |
|---|---|---|---|---|
| Xilinx Kintex-7/KC705 | HDMI (AES-FMC-IMAGEON-G card) | 1G Ethernet | Xilinx TEMAC controller | 720p25/30/50/60 & 1080p@30 |
Features List
