In collaboration with 10 of the world’s leading broadcast industry organisations, Sony yesterday launched the Networked Media Interface.
The new AV over IP interface delivers low latency and noise-free switching of HD and 4K video, audio, and metadata, as part of IP-based networking.
The Networked Media Interface packetises video, audio, and metadata, enabling real-time transmission between video-production products via standard network infrastructures. This technology is designed to enhance Sony’s IP Live Production system by increasing efficiency and reducing cost for the broadcasting of live studio and sports production.
The new Networked Media Interface combines the latest IP network technologies with a current SDI standard interface to support any resolution of video transmission. While conventional systems require multiple different types of cables to carry various signal types (video, audio, reference, metadata and control data), the Networked Media Interface requires only a single standard network cable passing through conventional network switches.
This new solution supports direct connection of numerous types of production devices onto the IP network via an existing Layer-3 IP switch infrastructure. Furthermore, it enables simultaneous transmission to multiple points and real time noise-free source switching, handling SD, HD and 4K video resolutions together.
Sony is also developing Low Latency Video Codec (LLVC) technology, which supports the video compression required for 4K 60p transmission over 10 Gbps Ethernet. The creation of SMPTE Registered Disclosure Document (RDD) for this codec technology is currently in process, while the company has also adopted SMPTE ST 2022-6 and ST 2022-7 - a technology which transports uncompressed HD-SDI over IP network.
As of today, the following 10 leading companies support Sony’s effort to promote the Networked Media Interface:
