The HDMI TX Subsystem also provides an option to support a native video interface. When
Native Video Interface is selected, the HDMI TX Subsystem is constructed without the
Video Timing Controller and AXI4-Stream to Video Out Bridge. Therefore, the HDMI TX
Subsystem is allowed to take native video from its own video devices and convert into
HDMI signals.In native video mode, the HDMI TX Subsystem still has a built-in capability to
optionally support both HDCP 1.4 and HDCP 2.2 encryption.
Figure 2-3 shows the internal structure of the HDMI TX Subsystem when Native Video
Interface is selected as video interface. In this illustration, both HDCP 1.4 and HDCP 2.2 are
selected.
