The Video Capture solution described in this block diagram is a subsystem in a video analytics application. The 4 analog input signals coming from the cameras are sampled and converted to standard BT656 digital streams with are fed into the FPGA.

Each stream is transfer to a video analytics block that performs image processing over the input data. In addition, each incoming video channel is also transferred directly to the PCIe IO block
The Analytics' bock's output Meta-data is combined with the raw image and transferred to the PC for further processing and display.
