The following four figures show the HDMI 1.4/2.0 TX Subsystem ports when AXI4-Stream is selected as the video interface. The VIDEO_IN port is expanded in the figure to show the detail of the AXI4-Stream video bus signals. The subsystem has the following default interfaces:
- AXI4-Lite CPU control interface (S_AXI_CPU_IN)
- AXI4-Stream Video interface (VIDEO_IN )
- AXI4-Stream Audio interface (AUDIO_IN )
Note: In the following diagrams, for all AXI4-Stream interfaces
video_data_width =
(int((3*BPC*PPC+7)/8))*8 and for all native interfaces video_data_width = 3*BPC*PPC. Figure 1. HDMI TX Subsystem Pinout – AXI4-Stream Video Interface (No HDCP)
