    Professional Streaming

    Through 4 x HDB-301R, it's easy to switch HDMI camera scenarios!

    When you transfer video from HDB-301R to PC with the resolution of 1920*1080 and 60 frames per seconds, the transferred bandwidth would occupy one USB 3.0 port. If you need more HDB-301R to input different HDMI sources, please be noted the USB 3.0 bandwidth must be independent, not shared.

    It is suggested to use a motherboard with Intel 100 series chipset (ps.1) and Skylake i7 CPU, or Intel 200 series chipset (ps.2) with Kaby Lake i7 CPU.

    Also please use a graphics card with built-in GPU (eg. NVIDIA GTX-1050: you could visit OBS and XSplit websites for suggestions on graphics card selection) and DDR4 RAM 16G

    If the performance of the USB 3.0 on the motherboard with 100/200 series chipset is not good or no enough, please additionally install USB 3.1 PCIe add-on cards (one add-on cad connects to one HDB-301R).

    OS: Windows 10 64-bit recommended.



    100 series chipsets (PCH): Z170, Q170, H170, Q150, and B150; DMI 3.0 channel.


    200 series chipsets (PCH): Z20, H270, B250..etc.; DMI 3.0 channel.
    DMI 3.0 channel- the bandwidth is increased to 8GB/s, which get rid of shared PCI-E bandwidth limitation of external devices. The above performance is for reference only; the tested result will vary according to actual configuration.



    i7-7700, 16GB RAM, GTX-1050 (4GB) graphics card, two USB 3.1 PCIe add-on cards, two on-board USB 3.0 ports.
