tvONE CM-HDMI-SC-2OUT-KEY – Dual HDMI Keyed Output Module
Product Overview
The tvONE CM-HDMI-SC-2OUT-KEY is a dual HDMI keyed output module designed for use in CORIOmaster video wall processors. It provides real-time luminance keying across two layers — background and foreground — enabling live compositing without visible latency. This module is compatible with the CORIOmaster C3-540 and CORIOmaster mini C3-510 chassis (sold separately).
Product Description
The CM-HDMI-SC-2OUT-KEY slots into any available I/O bay of the CORIOmaster or CORIOmaster mini chassis, adding two independently scaled HDMI outputs with integrated luminance keying. The keying engine operates on two layers: a background layer and a foreground layer. Any video content in the foreground that falls below the defined luminance threshold is keyed out, making the background layer visible through those areas. A softness parameter controls edge anti-aliasing, ensuring clean transitions between keyed regions rather than hard pixel edges. Keying is processed entirely in real time with no measurable latency, making this module suitable for live event production and broadcast environments. Both outputs deliver scaled HDMI signals, so source material at any resolution is scaled to fit the target display. The module installs without tools — it slides into the chassis bay and locks in place. Power is supplied by the chassis; no external power is required. For broadcast and live production environments where graphic overlays or keyed content must be composited onto video wall outputs, this module provides a hardware-based alternative to software compositing.
Key Features
- Dual HDMI Scaled Outputs — Two independent HDMI outputs, each with scaling, allow different content or resolutions to be driven from a single module slot.
- Luminance Keying — Hardware-based luminance keyer removes foreground content below a defined brightness threshold, compositing background and foreground layers in real time.
- Adjustable Softness — Edge softness parameter anti-aliases keyed boundaries, eliminating the jagged edges common with hard luminance cuts.
- Zero Latency Keying — Keying is performed in real time with no visible output latency, suitable for live production environments.
- Tool-Free Installation — Module slides directly into any CORIOmaster I/O bay and locks without tools, simplifying field installation and hot-swap maintenance.
- Chassis Power — Draws power from the CORIOmaster chassis; no external PSU or additional cabling required.
Typical Applications
- Broadcast studio — keyed graphic overlays on video wall outputs during live production
- House of worship — foreground text or logo keying over background video on large display walls
- Auditorium — live event compositing with keyed content on multi-display rigs
- Conference room — branded overlay compositing on executive display systems
- Training room — instructional overlay keying on video wall displays

Frequently Asked Questions
Which CORIOmaster chassis is the CM-HDMI-SC-2OUT-KEY compatible with?
This module is compatible with the CORIOmaster C3-540 and the CORIOmaster mini C3-510. The chassis is sold separately. It is not compatible with the CORIOmaster2 CM2-547 without confirming firmware and bay compatibility with tvONE.
How many CM-HDMI-SC-2OUT-KEY modules can be installed in one chassis?
The CORIOmaster C3-540 has 14 I/O bays available for modules. The number of keying output modules that can be installed depends on your total input/output mix. Each module occupies one bay and provides two keyed HDMI outputs.
What is luminance keying and how does it work in this module?
Luminance keying removes areas of the foreground layer that fall below a defined brightness (luminance) threshold, causing the background layer to show through those areas. This is commonly used to overlay graphics or text on video content. The module performs this entirely in hardware with no processing latency.
Is the CM-HDMI-SC-2OUT-KEY HDCP compliant?
Consult the tvONE datasheet or contact Creation Networks for current HDCP compliance details specific to this module's keying outputs.
Can the two outputs run at different resolutions?
Yes. Each HDMI output has independent scaling, so each output can target a different display resolution.
Does keying require additional software or licensing?
No. Keying functionality is built into the module hardware and controlled via the standard CORIOmaster software interface. No additional licenses are required.
What is the warranty on this module?
tvONE products are covered by a standard tvONE warranty. Contact Creation Networks at creationnetworks.net for current warranty terms and support options.
