    Every precious moment is captured by high definition 1080p resolution in 60 frames per second for you to enjoy high-speed and ultra-low latency video streaming.

    The uncompressed video transferred from different HDMI devices (as consoles, camera…) could be real-time edited while maintaining the best possible quality and primitive color saturation. Get rid of unnatural, delay, cumbersome!

    【 GTA5 Game Streaming 】

    Approved high definition resolution, different from others!

    Compatible Software Tool

    IEI HDB-301R is compatible with various live streaming software with DirectShow architecture, such as OBS, XSplit, PotPlayer, Wirecast, VLC media player, Skype, etc. You can use the software tools you are familiar with to play video games, watch HDMI while editing, recording, and streaming.

    Continuous Video Streaming

    IEI HDB-301R housing is made by ruggedized aluminum with excellent hot dissipation! One of the youtubers has done an 8-hour continuous steaming and enjoyed ultra-low latency without stop!

    Best Application
    Installation 1: Capture various HDMI video sources

    • Step1: Connect HDMI devices output to the HDMI-in of the HDB-301R.
    • Step2: Connect HDMI display device to the HDMI-out of the HDB-301R.
    • Step3: Connect the HDB-301R to PC/ notebook via USB 3.0 cable.
    • Step4: Run 3rd party DirectShow compliant software (ex: OBS, XSplit)

    Installation 2: Capture screen from HDMI extended desktop

    1.Notebook with HDMI output
    2.PC with dual display supported and at least one HDMI output

    • Step1: Connect PC/notebook to the HDMI-in of the HDB-301R.
    • Step2: Connect HDMI display device to the HDMI-out of the HDB-301R.
    • Step3: Connect the HDB-301R to PC/notebook via USB 3.0 cable.
    • Step4: Configure the connected HDMI monitor as an extended desktop and run the live stream software on the PC/notebook. Then, you will be able to use the HDB-301R to capture the video on the extended desktop.

    Do not put the video screen you want to capture on the same display with the third-party live streaming software; otherwise, the video captured by the third-party live streaming software will be displayed in endless loop.

    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.
