Video Decode Drivers for RTOS and Safety Critical Systems

CoreAVI's DecodeCore™ is a real time and safety critical H.264/MPEG2/VC-1 video decode driver that enables the hardware video decoder that is built-in modern graphics and system on chip processors. CoreAVI’s video decode drivers have been deployed in both airborne and ground control display systems globally, including UAV command and control, 360 degree situational awareness, Diminished Vision Enhancement (DVE), Geographic Information Systems (GIS), moving maps and various sensor warning systems.

DecodeCore enables applications to decode and display compressed video with much lower CPU usage than with a software-only decoder. The video decode drivers operates with CoreAVI’s ArgusCore™ ES/SC2 (CoreAVI’s family of OpenGL graphics libraries) graphics drivers.  The driver architecture and API ensures high efficiency and low latency between the video decode hardware and the graphics hardware.  The de-compressed video is also available as an OpenGL texture enabling complex hardware accelerated image manipulation and integration with 2D or 3D graphics.
