COLUMBIA, Md.—LTN, a major provider of IP-based video transport and network services, has been selected by PBS as its IP video partner to modernize and future-proof content distribution and contribution across more than 330 public television stations.

Under the multi-year agreement, LTN will implement a fully managed IP network, providing end-to-end connectivity, ISP services, and two-way video transport across all station locations and service sites.

“PBS is modernizing and strengthening its Interconnection system to future-proof the platform and support the future of public media. Our IP network delivers the scale, reliability, and flexibility required to support that transformation,” said Malik Khan, co-founder and executive chairman, LTN. “LTN is proud to provide the network, reliability, and operational foundation required to support one of the largest and most important media networks in the U.S.”

The LTN Network will support distribution of public television content, including PBS East and PBS West feeds, PBS KIDS, Create, NHK World, and FNX with the ability to deliver up to nine linear feeds to PBS member stations.

The platform will also enable always-on content sharing among stations and support station contribution workflows for regional and national distribution of locally produced content. In addition, LTN will power contribution workflows for OTT distribution platforms, PBS Platforms like pbs.org and PBS Digital.

“Moving to a scalable, IP-based infrastructure will increase reliability, reduce costs, and enable new opportunities for content sharing, collaboration, and audience reach across the entire PBS system,” said Dana Golub, Vice President of Strategic Infrastructure Initiatives at PBS.

The deployment will begin immediately and continue through the end of 2026.

LIÈGE, BELGIUM—With facilities under growing pressure to deliver more content while at the same time needing to cut costs, manufacturers are developing more and more tools that make the high-intensity live production environment easier, faster or more efficient.

As the world of content distribution has exploded with more channels, more enriched programming and the introduction of digital platforms as secondary – or increasingly, primary – media consumption devices, it’s important for those content owners to be able to produce the best possible programming with the most effective resources.

And that’s why the migration to IP is so important. There’s no shortage of articles, presentations or product messaging that tells us the benefits of migrating from SDI to IP infrastructures. Live production is the ‘next frontier’ that will benefit from IP connectivity. Once a migration to IP is complete, the industry as a whole will be able to do more as workflows won’t be restricted any longer by the limits of SDI and other similar signal flow methods.

OVERCOMING LIMITATIONS

SDI is point-to-point while IP enables multipoint connections. SDI moves data in one direction while IP is bidirectional. As SDI is moving one signal at a time, IP can handle multiple.

That’s not to say SDI hasn’t served us well for many years. I’ve worked a large portion of my professional life with SDI connectivity and it’s done some pretty outstanding - even revolutionary -things. And from the EVS point of view, and our IP4Live initiative, the move from SDI to IP must be an evolution rather than a revolution.

And the importance of this transition isn’t lost on broadcasters or content producers. In a recent survey of broadcasters by Devoncroft, the top five things that are on the minds of producers are either dependant or reliant on the update of IP-enabled infrastructures. These topics include IP networking and content delivery itself, multi-platform content delivery, file-based or tapeless workflows, virtualisation and 4K/UHD.

All of these things will benefit from the implementation of IP, and that’s why some of the largest technology providers in the industry have come together to form industry bodies such as the Alliance for IP Media Solutions (AIMS). The goal of industry-led groups is to accelerate and promote the open standards that broadcast and media companies use to move from SDI systems to an IP-based future – enabling all of the benefits it will bring.

And this is where we are with the transition from SDI to IP. There needs to be interoperability between the industry’s leading technology providers in order for any kind of transition to take place. This is perhaps best seen when it comes to standards. Collectives like AIMS bring together broadcasters, technology providers and industry standards organisations to eliminate the fragmentation that multiple flavours of IP bring. In addition, these organisations are helping to uncover the real-world use cases and ensure that the standards and recommendations for development will address these needs.

The Sandbox+ project run by the EBU and VRT in Belgium is a great example of what can be done in a fully-IP environment. The LiveIP studio - built at VRT’s production centre in Brussels – is a technology demonstration of many of the industry’s leading solution providers connected entirely by IP infrastructures. After extensive tests, the LiveIP studio has recently started producing and distributing programming for Ketnet, VRT’s children’s channel. This project is a clear significant step toward putting the benefits of fully-IP infrastructures into daily on-air production.

A STEADY, HYBRID TRANSITION

Even though pioneering projects like the Sandbox+ LiveIP studio demonstrate that this is possible, it’s highly unlikely that any broadcaster will start from scratch and implement an entirely IP-based infrastructure. The step we need to see next – and the step we will absolutely see – is a hybrid approach to the adoption of IP. Anyone upgrading to any form of IP-enabled workflow needs to continue to protect the investments they’ve made in SDI-based technology. While in the long-term, the OPEX of IP infrastructures is lower, that’s not to say everyone should use all of their CAPEX to install it.

EVS’ IP4Live initiative was put together to work alongside our clients and customers to show them how the SDI/IP hybrid approach to a transition is the best way to work. With that in mind, alongside our optional gateway solutions for existing live production servers that connect existing SDI-based solutions to IP infrastructures, our new product development and upcoming announcements will feature integrated IP-based options.

When it comes to IP technology, many people say there is plenty of work to be done. But we’re of the opinion that the work that has been done is of the utmost importance, and has significant value today. SDI is by no means dead. IP-enabled technologies will sit alongside SDI to enhance its operation and connect the live production environment.
