Portable 8K Live Transmission System Over Mobile Network Succeeds in Proof of Concept

Enables 8K live transmission without fiber installation

NHK Technologies, Inc., ASTRODESIGN, Inc, LiveU Japan K.K., SANSHIN ELECTRONICS CO., LTD. and NTT DOCOMO, INC. have announced the success of the Proof of Concept of an 8K live transmission system using LiveU, the portable live video transmission solutions which they have been evaluating and experimenting with since April 2020.

With this system, 8K live video transmission can now be practically introduced at a low cost and the utilization of 8K high-definition video is to be expanded in various types of content such as live broadcasting, entertainment, medical care, and monitoring systems. Taking advantage of the portability of this system, the introduction of 8K live transmission to road race coverage can also be a new opportunity.

This 8K live transmission system consists of a dedicated 8K camera AA-4814-B, LiveU 4K multi-cam live transmission field unit LU800 and decoder LU4000 connected over the mobile network, and the Video Correction Device newly developed by ASTRODESIGN can correct the difference in signal reception timing that may occur between each LiveU unit in real-time.

This also enables stable 8K video transmission by recognizing and correcting the 4G/5G wireless transmission interruption automatically. By using this system, the 8K video can be transmitted without fiber installation by LiveU over a 5G high speed wideband network.
