Designing video equipment for streaming multiple uncompressed video signals is a new challenge, especially with the demand for high-definition video streams. This white paper examines how a multichannel streaming PCIe DMA controller and other "building block" IP cores are combined within Altera’s Cyclone IV GX FPGA to support SD- and HD-SDI applications using an open-source video packet streaming-format protocol such as those used in non-linear editors, video servers, and video-capture applications.
