Kiloview Cradle Series

RU01/RU03 Rackmount Encoder/Decoder

A Free Mixture of 4/16/32 Channel

The Kiloview Cradle Series include RU01 or RU03 rack-mounted frame, freely mixed with 4 channels (RU01),16 channels/32 channels (RU03) encoder/decoder modules. It comes with redundant power modules, centralized heat dissipation, ensuring longtime stable operation, and benefits your IP video deployments of any size and complexity.

RE-3 Dual-channel 4K Rackmount Encoder

Kiloview RE-3 is the latest version of our Cradle series rackmount encoder, which enhances the capabilities of our previous RE-1 and RE-2. RE-3 has all the same great features of the original RE series rackmount encoder, but now it gets the same encoding performance as our E3 including 4K and dual video inputs support. With the upgraded encoding capabilities of RE-3, you can now encode 4K video at up to 30 frames per second or HD video at up to 60 frames per second. Dual-channel video inputs provide users with the highest level of flexibility, allowing them to encode both videos in multiple ways. HEVC technology also enables users to live stream to up to 8 destinations simultaneously. RE-3 is a versatile and cost-effective solution for video encoding in various industries. It can be used for live production, live streaming, remote transmission, and post-production.

High Density

You may need to use multiple devices in a workflow, and sources may change over time or from day-to-day. With Cradle, you can design 4 encoder and decoder modules in an RU01 chassis, 16x or even 32x in an RU03 chassis to make them work perfectly in your environment.

All inserted encoding and decoding module support SDI/HDMI+3.5mm audio, and the decoding module supports HD or 4K video output.

16 encoding decoding modules in RU03 chassis

High Flexibility

SDI? HDMI? All in, all out

No matter what video sources you have, SDI or HDMI, the Cradle is your ideal choice. 1RU/3RU is compatible with SDI and HDMI of both input and output; freely insert encoding and decoding modules in a chassis.

Cradle supports the most IP media protocols like SRT/RTMP/RTSP/UDP/HTTP/HLS and benefits NDI® HX version optional. So, a Cradle can be applied to many business scenarios.

High Reliability

Cradle is equipped with redundant power as standard, effectively preventing power failure. At the same time, dual cooling fans give Cradle Intelligent temperature control for automatic heat dissipation, ensuring stable and 24h continuous operating. For convenient use, Cradle offers power indicator light and operation indicator light to monitor working status.

Numerous Protocols Covered

All encoder/decoder modules support SRT, RTMP, RTSP, UDP, HTTP, HLS and other protocols, and you can also choose to customize NDI|HX function.

Easy to use

Cradle adopts a plug-in card structure to make sure card installation and replacement as easy as possible. You are free to mix and insert encoding and decoding modules with flexible application and replacement.

Production with Creative Features

Cradle Series support 3.5mm audio input, H.264/H.265 encoding, image and text overlay, video cropping, NAS network storage and other professional functions.
