My career in broadcast and media began back in 1971, and I've seen a lot of major technology changes since then: black and white to colour, mono to stereo, analogue to digital. Now we are in the middle of another massive shift - from SDI to IP - and while it is bringing plenty of benefits in making productions and operations more flexible and conducive to remote working, it is also presenting huge challenges as well.
Part of the problem on this occasion is that broadcast workflow needs are changing simultaneously in so many ways. Remote working and remote production were discernible trends before the pandemic - but have surely now accelerated as a result. This calls for more versatile access to content outside of the traditional studio environment, often using mobile connections or the domestic WiFi of reporters or producers. Meanwhile, the number of streaming platforms and services that content producers have to support is growing all the time.
It won't be a surprise to discover that the adoption of the cloud for production and managed services is already playing a big role in providing these more flexible workflows. Cloud services are maturing, and many broadcasters are in the process of implementing (at least) hybrid cloud/on-premises infrastructures. But the shift from SDI to IP networking is arguably proving more problematic as we haven't yet reached the stage where the interoperability issues have been resolved.
For example, there has been a lot of attention given to the SMPTE ST 2110 suite of standards, which have undoubtedly been a big catalyst for the IP movement. But at the moment our experience of it tells us that there are still some tricky areas. In particular, the support that vendors are offering for ST 2110 is variable - some are doing it very well, others less so. That means there is a serious possibility of interoperability issues between systems from different vendors - not something you want to have to contend with!
It's in this context that my team is currently looking towards NDI as a more capable and seamless route into broadcast IP. Developed as an open-source technology by NewTek, which was then acquired by Vizrt, it has more recently spun out into its own operational entity. Developed to allow real-time, ultra-low latency on existing IP networks, NDI offers several major advantages to broadcast users when compared to many other IP technologies.
Practical and cost-efficient Removing the need for costly networking and infrastructure investments, NDI is able to utilise standard Ethernet-based LAN networks, making it possible to connect every system in the MCR and related environments - including cameras, screens, production rooms, control and operational facilities. It also allows every enabled device and source to be visible on the network as a source or destination - giving MCR personnel a complete overview of the network at all times.
Moreover, in contrast to some technologies where the focus is on uni-directional transport, NDI enables multi-directional, two-way signal transmission over IP - to and/or from any NDI-enabled device. This makes the whole process much more efficient and a decisive step up from simply replacing SDI cabling with Ethernet. Other advantages of NDI include a codec that requires less processing power than many competitors, the ability to handle double-digit video streams using a Gigabit network connection, and the fact that it has already been tested extensively in real world' productions.
There are, however, two aspects in particular that we think will mean NDI truly goes the distance in broadcast. Providing a universal workflow, NDI is not beholden to resolution or format - meaning that it can continue to be used successfully as the industry moves from HD to 4K and even 8K. Of course, this also means that it can continue to be refined and augmented without affecting interoperability.
Indeed, with the increase in remote working and production on everyone's mind, the latest version, NDI 5, adds several significant new features, including NDI Bridge (for sharing NDI sources with others beyond your local network) and NDI Remote (sharing or receiving an NDI source over the web). The amount of production being done outside of the studio, and by smaller teams on-site and at home, will continue to increase - meaning that standardised technologies will become ever more critical. NDI provides precisely this kind of reassurance, and it's a key reason why we are supporting its roll-out in broadcast and in particular, the workflows that extend past production and into presentation, linear transmission and distribution. This is new territory for NDI.
The Three Media team have been very fortunate to engage directly with Dr Andrew Cross, the person responsible for bringing NDI to our industry and the wider world. He demonstrated just how comprehensive and flexible NDI is alongside deepening our understanding of the benefits that can be realised from the entire NDI developer and user community. It has been really exciting to work in partnership with Three Media to look how to innovate playout. Using NDI in the cloud we are putting together what is going to be the future of how production all the way through to presentation is pe
