LiveU LU4000 4K/Quad HD 1RU Rackmount Video Decoder Server

4K/quad HD rack-mount decoder for the highest video quality. Receive, decode, playout and stream any HEVC/H.264 4K or multi-camera video feeds.

Part of your workflowThe LU4000 is an essential part of your live video workflow, acting as your in-studio or on-site source for live feeds coming from any LiveU field unit or from the LiveU Matrix cloud video distribution platform.
Multi-purpose decoder
The LU4000 supports a single 4K transmission (over 12G-SDI) as well as up to four full HD independent transmissions from different units (over 4 x 3G/HD/SD-SDI). It also supports multi-camera productions: receiving and playing out up to four fully synced feeds from a single LU800 unit.Any output typeThe LU4000 can receive multiple preview feeds, allowing the remote operator to select the feed/s played out for local consumption. Built for maximum workflow flexibility, the LU4000 offers multiple output options including SDI, NDI, RTMP, MPEG-TS and SRT.
Live streams are managed and controlled via the LiveU Central cloud-based management platform or the LiveU Control+ App.
Enabling ground-to-cloud productions
Our decoders are also available in the cloud! LiveU's cloud-based decoders, "cloud channels", allow you to seamlessly receive LRT feeds from your LiveU field units and output them to various online/digital destinations and/or your cloud-based production platforms.

Supporting multiple protocols, including NDI, RTMP, MPEG-TS and SRT, the cloud channels can be dynamically added as supplementary channels alongside your physical receiver or utilized as your primary receiving channel.
Turn your LU4000 into a mobile receiver
Transmit live feeds from the field directly to your production truck as part of a cost-effective on-site production solution. Cut costs and reduce set-up times, by eliminating the need to set up line-of-sight infrastructure, cables and internet sourcing.

LiveU Matrix enabled
The LU4000 is Matrix enabled, allowing you to seamlessly share your live feeds with multiple internal and cross-organizational end-points, using cost-effective and reliable IP-based distribution over the public internet.

Powered by LRT
The LU4000 uses LiveU Reliable Transport (LRT), enabling it to optimize live video delivery to different SDI and/or IP destinations, dynamically adjusting bitrate and quality for the best viewing experience.
