All Silicon IP


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). Applications


The MJPEGOIP-HDE Subsystem is suitable for live streaming in broadcasting, surveillance, industrial, defense, and medical applications. The platform consumes significantly less energy than software-based solutions, making it ideal as a compression coprocessor in battery-operated devices with video streaming capabilities.
