Imagine, Sony Team on 4K Transport

Imagine Communications announced an industry initiative with Sony intended to enable the transition to UltraHD/4K video, and from legacy SDI to IP-based network infrastructures.

Today's studio cameras use one HD-SDI cable to carry a single uncompressed baseband signal that may require up to 3 Gbps. The increased bandwidth for UHD/4K would normally require four HD-SDI cables, which presents logistical challenges. To resolve the challenge, Imagine supports Sony's Networked Media Interface, a new AV-over-IP interface for IP-based networking designed to provide low latency transport of UltraHD/4K video, audio, reference, metadata and control data.

Sony's Networked Media Interface is intended to provide a nearly lossless UHD/4K compressed stream over IP signal via 10 GigE fiber or twisted pair cabling.
