Sony develops AV over IP Interface – enabling network-based video transmission and synchronous, noise-free switching of HD and 4K video, audio, and meta data

New licensing program promotes industry-wide deployment

Las Vegas, NAB, April 6 2014: Sony is actively developing IP-based approaches for professional video production, and has developed a new AV over IP Interface. This packetizes video, audio, and metadata, enabling real-time transmission between equipment via standard network infrastructures. Taking use of this technology, Sony configures IP Live Production system in order to increase operational efficiency and to reduce system cost for broadcasting studio and sports live production. To promote AV over IP Interface to be widely used in various video-production products, Sony has newly developed LSI, and technical specifications that enable the deployment of related FPGAs (Field-programmable gate array).

Sony plans to have a licensing program open to manufacturers of video-production products. Sony has today demonstrated real time transmission and switching of a live 4K broadcast over an IP-based AV routing system, using a new IP Live System Manager, the system’s core software and SDI-IP converters built around this new technology.

AV over IP Interface

Sony’s approach combines the latest IP network technologies with current SDI standard interface for 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), this new approach requires only a single standard network cable passing through conventional network switches. Sony has combined unique pieces of technology with already established standards to achieve reliable, scalable and stable transmission. This new technology supports direct connection of numerous types of production devices onto the IP network. Furthermore, it enables simultaneous transmission to multiple points and real time noiseless source switching, handling SD, HD and 4K video resolutions together. The new IP Live Production system has been designed to be flexible and scalable, since users have the ability to migrate to greater capacities (number of devices) and higher video resolutions including HD to 4K over time.

Licensing Program Launch

Sony intends to have a licensing program for AV over IP Interface for manufactures of video-production products in order to widely promote adoption of this technology. This licensing program will provide Sony’s LSI which implements this technology and license to manufacture FPGA IP core. Sony will actively collaborate with FPGA solution providers. Xilinx will be working with Sony under licensing program to enable the deployment of programmable-based video-production equipment. In addition, Sony will continue to collaborate with other thought leaders in the video over IP solutions space, Altera Corporation and Macnica Americas Inc. as FPGA solution providers, who continue to innovate in next generation video over IP solutions.

IP Live System Manager and SDI-IP converter

Technology Exhibition
The IP Live System Manager controls communication among all devices, including SDI-IP converters. Sony’s unique algorithms deliver optimal management of network resources, and perform Quality of Service techniques to provide required levels of stability for real-time transmission.

The SDI-IP converters will offer IP interface capability to any conventional SDI based equipment, which is crucial for the wide adoption of AV over IP. This conversion approach allows for existing assets to be maintained while the transition to full IP systems is ongoing. While the IP Live System Manager and the SDI-IP converter are still under development, Sony expects to bring these products to market by the end of 2014.

It performs stable transmission of 4K live signals with low latency over IP, using multiple 4K sources supplied through different sources converted from SDI to IP, then routed over the network down to their monitoring destination.

Sony is set to bring a number of systems to market that integrate this new AV over IP Interface technology, in order to build IP environments. These innovations will include routing AV over an IP interface in remote production systems, so as to connect devices in remote locations via an IP network. As with all AV over IP Interface technology, these systems will transmit video, audio, reference, metadata and control data signals by remote operation, significantly reducing production costs.

At NAB 2014, Sony is exhibiting on stand Booth #C11001 in the Central Hall, Las Vegas Convention Center.
