When configured with the AXI4-Stream interface, the subsystem is packaged with three subcores:
- DisplayPort Transmitter core
- Video Timing Controller (VTC)
- DP AXI4-Stream to Video Bridge
In MST mode, the subsystem also includes a dual splitter. In SST mode, the subsystem also includes an optional HDCP controller for encryption and an AXI Timer core as a helper core for HDCP functionality.
Because the DisplayPort TX Subsystem is hierarchically packaged, you select the parameters and the subsystem creates the required hardware. The following figure shows the architecture of the subsystem assuming MST with four streams. The subsystem includes a multi-pixel AXI4-Stream Video Protocol interface.

Note: MST HDCP is not supported.
