HDMI Transmitter (TX) Subsystem v2.0 - Can YUV 4:2:2 12-bit interlaced SD (480i60 and 576i50) resolutions be supported?

Description

Can YUV 4:2:2 12-bit interlaced SD (480i60 and 576i50) resolutions be supported?

Solution

AXI4-Stream Interface:

When using the AXI4-Stream interface, the HDMI Transmitter Subsystem cannot support YUV 422 12-bit interlaced SD (480i60 and 576i50) resolutions.

This is because the AXI4-Stream to Video Bridge inside of the HDMI Transmitter Subsystem does not support pixel replication as required by the HDMI specification.

Native Interface:

When using the Native interface, you can support YUV 422 12-bit interlaced SD (480i60 and 576i50) resolutions, but you will need to add your own pixel replication logic to comply with the HDMI specification.
