HDMI IIC control data
Part 3.5: HDMI Input Interface
There are 2 HDMI input ports on the backplane. We use ADV7619 HDMI
decoding chip from Analog Device, which supports up to 4K@30Hz input and
data output in different formats. In addition, the EDID data of HDMI is
configured by the FPGA internal program, the I2C bus is connected to the
HDMI interface through the level conversion chip, and the external HDMI
output device can read the EDID information on the board through the bus. The
hardware connection of the HDMI input interface is shown in Figure 3-5-1.
