HDMI (VGA/CVBS) to SDI Converter​

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​

Exceptional Video Decoding
It supports 4K H.265/H.264 IP stream decoding, capable of simultaneously decoding and outputting up to 12 video streams, including 12 channels of 1080P30, 12 channels of 1080P60, 3 channels of 4KP30, and 2 channels of 4KP60. Additionally, the device supports SpeedHQ (NDI HB) decoding format, enabling simultaneous decoding and output of up to 4 video streams, including 4 channels of 1080P30, 4 channels of 1080P60, and 1 channel of 4KP30.
Powerful Audio Decoding
D350 also offers flexible audio output options, supporting output via embedded SDI/HDMI or 3.5mm Line out, with the capability to decode up to 2 HDMI and 4 SDI audio channels. It is compatible with AAC, G.711, Opus, and LPCM audio formats and can be expanded to support additional formats and channels. Thanks to its powerful multi-channel audio mixing and gain adjustment capabilities, users can freely toggle between multiple audio channels, mix audio, and adjust the audio gain flexibly.

Comprehensive Streaming 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.

Flexible Layout and Overlay Features for Easy Custom Output

100% Customizable Flexible Layout
D350 supports customizable output display screens, allowing users to freely choose between single-screen or various split-screen and picture-in-picture modes. You can dynamically select custom layouts ranging from 1/2/3/4/5/6/7/8/9 to 16 screens based on your needs, easily achieving dynamic output switching. All layout parameters, including position, size, and dimensions, are 100% customizable. You can also save custom multi-screen layouts, including the position and size settings of different video panes, as templates for future use.
Personalized Template Creation for Custom Output
The newly added overlay editor feature of the D350 provides you with an unprecedented personalized output experience. You can freely create rich and colorful overlay templates for the output screen, incorporating various elements such as images, text, colors, and more (e.g., LOGO, borders, image-text overlays). The designed templates can be directly applied to the corresponding output screens, making the output more vibrant and personalized.

Multiple Interfaces, Customizable Outputs​

D350 supports multi-interface output via 3G-SDI and 2*HDMI 2.0, enabling synchronous decoding and the display of identical or different images. The HDMI output supports resolutions up to 4KP60, while the SDI output reaches up to 1080P60. Both the output resolution, scan type (progressive or interlaced), and frame rate are fully adjustable. Additionally, D350 supports specific frame rates (such as SDI with 59.94/29.97), allowing for tailored performance to suit your needs.

*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

Output Up to 3840x2160 @ 60Hz

SDI

Output Up to 1920x1080 @ 60Hz

Low Latency and High Quality​

D350 guarantees outstanding image quality and low transmission latency with a decoding delay of around 150 ms and a packet loss rate of less than 10%.

Simplified UI for Easy Operation

The brand-new UI interface is simple and intuitive. The perfect combination of the main screen and sidebar preview layout allows for easy previewing of multiple full-format video streams. With just a drag, users can seamlessly switch between real-time preview and corresponding output. All functions are integrated on the web page, making them clear and easy to access.

Additionally, the interface supports VU meter monitoring and reverse PTZ control, making monitoring even more efficient. Whether it’s monitoring audio or controlling cameras, the system ensures smooth and easy operation.

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.

16 Preview + 9 Output with Dynamic Switching​

You will be able to pick 12 of the streams for output on the displaying screen from the 16 real-time video streams or images previewed on the web page. You can add video sources, select any video source for decoding, and perform dynamic switching.

Audio and Intercom​

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

Dual Ethernet Ports with 1 PoE

D350 is equipped with dual Gigabit Ethernet ports with one PoE power supply and redundancy protection, ensuring uninterrupted network connectivity. With just one cable, it simultaneously supports power, video IP transmission, and intercom functions, simplifying wiring and improving system efficiency.

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.
