New Generation True 4K UHD Audio & Video Decoder, Fully Featured to Meet Your Multi-Channel Decoding Needs:

D300 4K Ultra HD Decoder is a professional hardware decoding device that decodes multiple network video streams (such as NDI|HX/SRT/RTSP/RTMP/RTMPS/RTP/UDP/HLS, etc.) and outputs SDI and HDMI video signals. The D300 supports 4K resolution output and simultaneous decoding of up to 9 video streams, with fully customizable split-screen display, background/LOGO overlay, 16-channel monitoring + dynamic switching, and other versatile functions.

Ultra HD Video Output

Supports decoding 4K H.264/H.265 IP streams to 3G-SDI and 4K HDMI, with simultaneous decoding and output of 9 video streams. No screen tearing or lagging, delivering ultra HD video quality that shows every detail for a smoother experience.

(9 channels at 1080P30, or 8 channels at 1080P60, or 4 channels at 4KP30)

Full Protocol Support

● Supports decoding of dedicated video protocols including NDI|HX (2.0) and SRT;

● Supports decoding of common video protocols such as RTMP/RTMP Server/HLS/TS over UDP/RTP/RTSP, fully meeting diverse application requirements.

Low Latency & High Image Quality

The D300 features decoding latency below 200ms and strong packet loss resistance with a packet loss rate under 10%, ensuring clear, smooth and undistorted decoded output.

Built-in RTMP Server Function

With RTMP Server enabled, video encoders can send streams directly to the decoder via RTMP for decoding and output, eliminating the need for an RTMP relay platform for simple, convenient and low-latency transmission.

Dual Output Interfaces with Identical or Different Signals & Adjustable Resolutions

HDMI output up to 3840×2160@60Hz, SDI output up to 1920×1080@60Hz. Output resolution, progressive/interlaced scan and frame rate are all adjustable. The D300 also supports special frame rates (SDI supports 59.94/29.97, etc.) to meet specialized requirements.

Customizable Multi-View Layouts

Output can be set to single-view or customizable split-screen/PiP modes, with dynamic selection of 1/2/3/4/5/6/7/8/9 divisions for dynamic switching. Position, size and dimensions are fully customizable. Output resolution and frame rate are also adjustable.

16-Channel Real-Time Preview + 9-Channel Dynamic Output Switching

Supports "Preview + Output" mode. You can preview 16 real-time video streams via the web interface and select up to 9 streams for on-screen output.

Ideal for PVW/PGM workflows (left preview + right output).
