The DisplayPort AXI4-Stream to Video Bridge maps the video over the AXI4-Stream interface to native video format as required by the DisplayPort Transmitter IP core. The bridge uses the AMD AXI4 to Video Out core to convert the format between AXI4-Stream and DisplayPort native video.
The following table shows the color mapping for the AXI4-Stream interface.
