1.5. AD Calibration Test
As SoC as built-in A/D self-
calibration mechanism, there’s not any ADC to perform.
1.6. DDC & EDID & T-Link Test
The E-EDID data structures are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for
HDMI). CEA Timing Extension structure has been extended to support all 3D capable timings.
All HDMI structures have their own BIN profile which are part of main SW and uploaded at
power-on into HDMI switch chipset:
For EDID check, it’s needed to check whether the correct EDID is downloaded by checking
corresponding EDID NVM Checksum or read them out to check bit by bit if it is in line with the
released EDID bin file.
1.7. HDCP Test
