Figure 6-10 Launching the HDMI TX Demonstration using the "demo_batch" Folder

•

Wait for a few seconds for the LCD monitor to power up itself. And you should see a

pre-defined video pattern shown on the monitor, as shown in

Figure 6-10



Demonstration Operation

The demonstration involves certain activities the user could perform to interact with the on-board
HDMI encoder.

Auto Hot Plug Detection

The demonstration implements an interrupt-driven hot-plug detection mechanism which will
automatically power on the encoder chip when the HDMI cable is plugged into the development
board and the LCD monitor is connected and powered on at the other side of the cable.

If the HDMI cable is already plugged into the on-board HDMI connector before powering up the
development board, the monitor-sense signal will trigger an interrupt to power up the HDMI
encoder.
