The BG-4KCH is a compact 4K video capture device that allows users to capture HDMI signals from sources such as gaming consoles, cameras, computers, and media players, and transfer them to a laptop via USB-C for recording or streaming. Designed for versatility and ease of use, this unit delivers crisp 4K video quality while maintaining a portable form factor ideal for both stationary and on-the-go applications.

Connectivity and Quality

Supporting resolutions up to 4K2K at 30Hz, the BG-4KCH offers flexible connectivity through both USB 3.1 Gen 1 and USB 2.0 interfaces. Over USB 3.1, the device supports RGB, YUY2, and NV12 video formats, while USB 2.0 supports YUY2 and NV12 with a maximum resolution of 720p at 30Hz. HDMI audio is captured in 2-channel, 16-bit PCM format, and the unit is fully compliant with UVC 1.0, 1.1, and 1.5 standards. With a maximum data rate of 350Mbps and broad compatibility across Windows, macOS, and Linux, the BG-4KCH is suitable for virtually any streaming or capture setup.

Features In-Depth

Beyond its basic capture capabilities, the BG-4KCH features several advanced enhancements that improve its performance and usability. The unit supports automatic video format detection, enabling true plug-and-play operation by recognizing the input signal without requiring manual configuration. It also features deinterlacing support, which converts interlaced video into a smoother progressive format for cleaner visuals during playback. Additionally, the built-in upscaling function can scale lower-resolution inputs up to 1080p at 60Hz, providing flexibility when working with a variety of source resolutions. With its compact size, automatic configuration features, and video enhancement capabilities, the BG-4KCH is a reliable and efficient solution for high-quality video capture in any environment.
