and engineering support
Overview
The BG-4KBHS-PRO is a professional-grade HDMI 2.0 and 12G/6G/3G/HD-SDI cross-converter and scaler built for high-performance signal conversion, monitoring, and analysis. Designed for broadcast, production, and professional AV applications, it supports up to 12G-SDI 4K60 and HDMI 2.0 4K60 video formats for seamless interoperability across a wide range of devices. Featuring an integrated 3.5” LCD display and intuitive push-button controls, it enables real-time signal monitoring and effortless on-screen configuration of video, audio, and output parameters.
Beyond simple conversion, the BG-4KBHS-PRO is a comprehensive diagnostic and calibration tool. Its advanced waveform and audio metering functions, combined with built-in test patterns and flexible scaling capabilities, make it an indispensable device for field engineers, content creators, and AV technicians who demand precision and reliability in every workflow.
Features in Depth
At its core, the BG-4KBHS-PRO delivers unparalleled flexibility with support for both HDMI 2.0 and SDI (12G/6G/3G/HD/SD) formats. It can simultaneously convert HDMI to SDI or SDI to HDMI, allowing cross-format workflows without compromising quality. The unit supports SDI bandwidths up to 11.88 Gbps and HDMI up to 18 Gbps, enabling full 4K60 (YUV 4:4:4) transmission with accurate color reproduction and low-latency performance. Its built-in scaler and deinterlacer ensure smooth playback and optimal display compatibility across various resolution standards, including VESA output modes.
For professional video analysis, the processor provides YCbCr waveform display, RGB monitoring, and audio level metering, viewable directly via the OSD or LCD interface. Engineers can access a suite of built-in test patterns to evaluate signal integrity, perform color calibration, or verify display alignment. The noise reduction, video enhancement, horizontal/vertical mirroring, zoom, and underscan functions offer extensive image control capabilities to fine-tune visual output in any setup.
Audio flexibility is equally robust, with S/PDIF-based embedding and de-embedding, ensuring precise audio management during signal conversion. The push-button interface enables fast access to all key settings, while firmware upgradability guarantees compatibility with future standards and extended functionality over time. Compact, durable, and highly versatile, the BG-4KBHS-PRO is an all-in-one solution for modern video signal conversion and real-time quality assurance.
