Apantac presents a practical look at the infrastructure layer behind broadcast control rooms, live production racks, OB workflows, and AV monitoring environments: multiviewers, KVM over IP, converters, DAs, switchers, extenders, and openGear cards. The focus is not one single box, but the way different signal types can be monitored, routed, converted, extended, and controlled across mixed HDMI, SDI, 12G, DisplayPort, fiber, copper, and IP systems. https://www.apantac.com/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The multiviewer section shows Apantac’s compact and modular approach, including UHD outputs, 12G inputs, HDMI models, openGear versions, and TAHOMA-style mix-and-match I/O layouts. The demo combines different resolutions and formats such as 1080p60, 2160p59.94, HDMI, and 12G-SDI on the same display wall, with audio meters, clocks, labels, logos, text overlays, and configuration software for control-room-style monitoring.
A major part of the booth is Apantac’s KVM over IP system, demonstrated with 4K video over a 1Gb Ethernet network and very low visible latency. The setup includes HDMI input and output, USB control, copper and fiber network connectivity, and the ability to switch between multiviewer mode and KVM control. User access management is also shown, including different accounts and permission levels such as view-only, control, occupy, exclusive access, or disabled.
The “video plumbing” area covers the less glamorous but essential part of professional AV and broadcast design: HDMI distribution amplifiers, HDMI switchers, SDI/HDMI/DisplayPort conversion, extenders, embedders, de-embedders, rear modules, and card-based versions for openGear frames. These are the devices that keep complex systems interoperable when sources, monitors, routers, production switchers, and computer workstations all need to speak different video formats.
Filmed at NAB 2026 in Las Vegas, the interview also gives a sense of how Apantac’s product range has expanded over 18 years of NAB appearances. Thomas Tang explains the company’s three main categories with a clear engineering mindset: multiviewers for seeing everything, KVM over IP for controlling workstations remotely, and modular video tools for connecting everything else without redesigning the whole rack.
