The following table shows the signals for the AXI4-Stream video interface, which supports 4 and 8 pixels per clock with 8 bits, 10 bits, 12 bits, and 16 bits per component for RGB, YUV444, and YUV420 color spaces. The color depth in YUV422 color space is always 12-bits per pixel. This interface is an AXI4-Stream slave interface and runs at the s_axis_video_aclk clock rate. The data width is user-configurable in the Vivado IDE by setting Max Bits Per Component (BPC).

For more information on the video AXI4-Stream interface and video data format, refer to the AXI4-Stream Video IP and System Design Guide (UG934).
