The Blackmagic Design BMD-VHUBSMARTE12G4040 is a highly advanced professional routing switcher designed for large-scale broadcast facilities and production houses that require immense signal distribution capabilities. As a 40x40 router, it provides 40 inputs and 40 outputs, all supporting 12G-SDI, which allows for the routing of ultra-high-definition video signals up to 4K at 60 frames per second on a single BNC connection. The "Smart" designation refers to its sophisticated control software and automatic signal management features, which intelligently handle format detection, cable equalization, and re-clocking to ensure signal integrity across large installations with long cable runs. Its core function is to act as the central nervous system for video and audio signals, enabling any source to be instantly directed to any destination, such as control rooms, edit suites, and transmission feeds.

This model stands out for its fully redundant, hot-swappable power supplies and cooling fans, which are critical for 24/7 broadcast operations where system failure is not an option. The modular design allows these components to be replaced without powering down the unit, ensuring continuous uptime. The router is managed via the included Smart Videohub Control Software, which provides a clean, intuitive interface for configuring massive routing grids, creating presets, and setting up automatic salvo switching for complex, timed events. Additionally, it supports third-party control via Ethernet using industry-standard protocols like Ember+, Sony P2, and others, allowing for seamless integration into existing facility control systems and automation.

Beyond basic routing, the Smart Videohub includes advanced features for signal monitoring and embedding/de-embedding. Each input and output features full multi-rate SDI monitoring with support for closed captions and ancillary data. The router can also embed audio from external sources onto SDI outputs or de-embed audio from incoming SDI feeds to send to separate audio consoles, providing exceptional flexibility in audio-video workflow. Housed in a robust 4RU rack-mountable chassis, it is built for demanding environments, offering a scalable and future-proof solution that consolidates routing for HD, Ultra HD, and 4K DCI workflows into a single, reliable unit.
