EX 2C Video Input
Max Number of Unique Inputs
Section titled “Max Number of Unique Inputs”HDMI 2.0 video input is supported from Designer software version r32.2 onwards. This must be used with EX 2/EX 2C/EX 3+ OS version 25Q3 onwards following an update to the Deltacast SDK, which resolves TA-52. This means that up to 2x 4K DCI inputs or 1x 4K DCI + 4x Full-HD inputs are supported any one time via the following physical connections:
- 1x HDMI 2.0 capture (HDMI connector)
- 2x 12G SDI inputs via Ports A and C (HD-BNC connector), or 4x 3G SDI inputs (HD-BNC connector)
The following table shows all possible maximum input configurations:
| Supported Configurations | 3G-SDI | 12G-SDI | HDMI 2.0 |
|---|---|---|---|
| 12G + HDMI | 0 | 1 | 1 |
| Full-HD + HDMI | 4 | 0 | 1 |
| 2x 12G | 0 | 2 | 0 |

HDMI 2.0
Section titled “HDMI 2.0”All video standards outlined here have been tested up to the following:
- Bit depth - 8/10/12/16-bit, but anything above 10-bit will be treated as 10-bit
- Colour Formats - YCbCr 4:2:2, YCbCr 4:4:4, RGB Limited, RGB Full (all modes).
- Note that HDMI 2.0 has a bandwidth limit of around 18Gbps. This means at higher resolutions and refresh rates (eg. 4k@60) , the colour format might need to be dropped to YCbCr 4:2:2 for it to be accepted.
