The OSVP IP block provides complete multi-video format conversion and compositing in a single IP block. All interfaces conform to the AXI4 protocol. Xilinx COREGen and EDK integration is also supported. Thus the OSVP block can be easily interfaced to video IP components from the Xilinx VIPP suite which is bundled with this IP module.

The block can be configured for up to eight video channels, which may be of different video standards. Each of these inputs can be de-interlaced and resized, then composited onto the video output. Each video output can comprise a single video input or a composite multi-view of multiple video inputs, facilitating quad-split display, etc.

The OSVP block has been optimised for Xilinx FPGA technology and achieves the highest broadcast quality video processing in an extremely small footprint IP core.

A series of reference designs are available called RTVE (Real Time Video Engine). These designs integrate the OSVP IP with Xilinx VIPP in a complete working FPGA design targeted for a range of hardware platforms.
