The 12G-SDI Playback and Capture System is a versatile FPGA-based solution designed for video capture and playback over Quad 3G-SDI interfaces. The system includes an FPGA image set for generating test patterns, capturing data from SDI inputs, and playing back over SDI. It can be integrated with a PCIe interface for enhanced performance in host machines, featuring Linux-based software and drivers to facilitate video processing. This IP core is available independently or paired with the High Performance FPGA PCIe Accelerator Card, offering a robust solution for applications requiring high-definition video handling and processing.
