D350 4K Ultra HD Decoder is an all-in-one video processing device that supports decoding various network video stream formats, including NDI HB, NDI HX/HX3, SRT, RTMP, UDP, RTP, and RTSP, with stable audio and video synchronization via 3G-SDI and HDMI. It can decode up to 12 simultaneous 1080P60 video streams and features hardware-based Multiview monitoring for real-time preview switching.
The D350 also offers customizable layouts, dynamic switching, and background/LOGO overlays, along with audio bar monitoring and reverse PTZ control. Its LCD screen displays the IP address and output status, providing easy monitoring for users.
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.
To accommodate your various workflows, D350 is compatible with all protocols, including NDI High Bandwidth, ND HX2, NDI HX3, SRT, RTMP, RTMPS, HLS, TS over UDP, RTP, and RTSP.
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.
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.
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: It supports three video source inputs, from which two can be selected for image output.
D350 guarantees outstanding image quality and low transmission latency with a decoding delay of less than 100 ms and a packet loss rate of less than 10%.
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.
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.
You will be able to pick 12 of the streams for output on displaying screen from the limitless real-time video streams (based on your hardware performance) 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.
D350 comes with dual USB ports, allowing you to extend to USB headsets for multi-party voice communication. By implementing Kiloview Intercom Server (KIS) , you can easily integrate a variety of devices, including Kiloview codecs, computers, smartphones, iPads/tablets, and custom Kiloview portable devices.
D350 seamlessly integrates with KiloLink Server, optimizing media transmission across all Kiloview products using any available network links. It enables efficient management, monitoring, and control of all devices throughout the process.
With optimized API, D350 offers a more convenient interface for video stream functionality development. Utilizing the included demo program, developers can quickly integrate and call features, streamlining the development process and improving efficiency.
