HDMI Video Capture
The EX 3+ and EX 2C servers support 4K DCI HDMI 2.0 video capture, in addition to 12G-SDI capture. This enables flexible combinations of HDMI and SDI inputs, depending on the server model and licensing.
Supported input configurations
Section titled “Supported input configurations”That means the EX 3+ can support simultaneously:
- 1x 4K DCI 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)
That means the EX 2C can support simultaneously:
- 1x 4K DCI HDMI 2.0 capture (HDMI connector)
- 1x 12G SDI inputs via Port A (HD-BNC connector), or 4x 3G SDI inputs (HD-BNC connector)
or
- 2x 12G SDI inputs via Ports A and C (HD-BNC connector)
Supported colour formats and bit depth
Section titled “Supported colour formats and bit depth”HDMI 2.0 capture has been tested with the following:
- Colour formats - YCbCr 4:2:2, YCbCr 4:4:4, RGB Limited and RGB Full.
- Bit depth - 8, 10, 12 and 16-bit, but anything above 10-bit is processed as 10-bit.
HDMI 2.0 carries a bandwidth limit of around 18 Gbps. At higher resolutions and refresh rates (4K at 60 Hz, for example) the colour format may need to be dropped to YCbCr 4:2:2 for the signal to be accepted.
If a source sends RGB Full but reports itself as RGB Limited, enable Process HDMI RGB Limited as Full on the Video Input Clip so Designer processes it as the RGB Full data it really is, and no colour depth is lost. See Setup Video Input.
SDI capture on servers that are also equipped with HDMI capture is 10-bit YCbCr 4:2:2 in all modes. For the full list of tested video standards on each server, see EX 2C Video Input and EX 3+ Video Input.
Requirements
Section titled “Requirements”To enable HDMI video capture, all of the following requirements must be met:
- Designer r32.2.4 or later
- The appropriate 25Q3 OS image or later must be installed for the server model, as specified in the Product Compatibility table.
Server support summary
Section titled “Server support summary”The table below summarises the input and output capabilities for HDMI.
| EX 2C | EX 3+ | Solo (Legacy) | |
|---|---|---|---|
| 4K Inputs | 1x HDMI 2.0 and 2x 12G inputs for 2x 4K inputs, or 4x 3G inputs (HD-BNC) | 1x HDMI 2.0 and 2x 12G inputs for 3x 4K input, or 4x 3G inputs (HD-BNC) | 2x HDMI 1x 4096x2160 @30 Hz or 2x 1920x1080p @60Hz |
| 4K Outputs | 2x 4K outputs (DisplayPort 1.4) | 3x 4K outputs (DisplayPort 1.4) | N/A |
Licensing considerations
Section titled “Licensing considerations”Licensing imposes the following limitations:
The EX 2C is licensed to accept up to two 4K / 12G input at a time.
If both 12G-SDI inputs are active, any 4K HDMI signal presented to the HDMI capture input will be rejected.
The EX 3+ supports three concurrent 4K / 12G inputs, which may be any combination of HDMI 2.0, and 12G-SDI.
These limits are enforced at runtime and cannot be overridden.
