D350 4K H.265/H.264 Decoder

Professional 4K Video Decoder

The D350 is a professional hardware decoding device that can simultaneously decode up to 9 network video streams and then output them through both 3G-SDI and HDMI interfaces in synchronization, with up to 4Kp60 output resolution.

With a built-in LCD screen, users can monitor the IP status and decoding parameters in real-time.

The D350 additionally allows dynamic switching, background / LOGO overlay, custom split display of a video stream, and other features.

Outstanding Decoding Performance

The D350 concentrates on every decoding detail for a better decoding quality.

D350 supports simultaneous decoding of up to 16 channels of video streams(It depends on the resolution*). It allows for customization of multi-output display including grid and PIP. With D350’s incredible performance and three output ports(two HDMI 2.0 ports and one 3G-SDI port), It’s also capable for outputting in three ways: Independently, Combine multi-channels video flows or replicate of one single flow to stream simultaneously.

Besides outstanding performance in video decoding, D350 is also super powerful in audio decoding. With a long list of audio formats supported including AAC/AAC/MPEG-4/MPEG-2/G.711/Opus/LPCM, It’s also capable of switching audio On/Off, audio mix and audio gain in real time to output alternatively through its HDMI ports, SDI port and 3.5mm line out port.

*Up to 16 channels of 1080P30, 9 channels of 1080P60, 4 channels of 4KP30, 2 channels of 4KP60 or 1 channel of 4Kp60 in NDI High Bandwidth.

Full Protocols Supported to Meet All Your Demands

To accommodate your various workflows, the D350 is compatible with all protocols, including NDIHX2, NDI|HX3, NDI High Bandwidth, SRT, RTMP, RTMPS, HLS, TS over UDP, RTP, and RTSP.

Multiple Interfaces, Customizable Outputs

D350 allows users to freely choose the output interface among 3G-SDI and 2 of 4K HDMI for outputting the same or different video sources in synchronization.

*Note: HDMI output up to 3840×2160 @60Hz, SDI output up to 1920×1080 @60Hz and can support frame rates such as 59.94/29.97

LCD Screen for Realtime Status Monitoring

As an update to the D300, D350 is equipped with a 0.9-inch LCD screen for a better user experience. With the built-in LCD screen, users can easily check the IP and decoding status in real-time.

RTMP Server Supported

With RTMP Server, D350 can simplify the video decoding workflow by directly accessing a video encoder and outputting video streams through RTMP without any relay platform.

User-Defined Display for Free Output

Free Layout: The users will be able to customize the output display in grids or a free layout like PIP, PBP, or POP.

Free Resolution: D350 also supports the adjustable output resolution, de-interlace, and frame rate.

16 Preview + 9 Output with Dynamic Switching

You will be able to pick 9 of the streams for output on displaying screen from the 16 real-time video streams or images previewed on the web page.

Unlimited video sources can be added, any video source can be freely selected for decoding, and dynamic switching can be performed.

Customized Output Background and OSD

Users can configure background subjects including LOGO, frame, and graphic overlay with the D350. The PVW window will also display the personalized information at the same time.

Audio and Intercom

Real-time intercom can be realized through the USB expansion headset. For group communication, you can deploy the Kiloview Intercom Server (KIS).

Centralized Management with KiloLink Server

D350 can connect to the KiloLink Server seamlessly which can optimize media transmission by any Kiloview products using any available network links. It helps to manage, monitor and control all the devices throughout the process.
