The Winter Olympics are in the midst of Week 1, and it has already been a challenging one: two consecutive days of alpine events had to be rescheduled because of high winds. And, for the team at Olympic Broadcasting Services (OBS) and the dozens of rightsholders onsite, the change in plans has required juggling of schedules, personnel, and technical facilities. But, for Sotiris Salamouris, chief technology officer, OBS, preparing for such occurrences is in the Winter Games' DNA.
OBS CTO Sotiris Salamouris and his team continue to embrace new technologies, like 5G wireless, to improve the production and technical services at the core of the Winter Olympics production.
While the Winter Games are smaller than the Summer, the possibility of cancellations and delays are much higher, and it can wreak havoc with the schedule, he says. The only way to deal with these sorts of changes is to have the resources available to be able to adapt and to use technology to help.
The challenge of handling cancellations and delays is not only about coming up with another production plan. It's also about making sure that all the downstream processes, like the apps and other ways in which content is distributed, are instantly aware of the new reality.
Digital platforms have to be accurate as to when things start and stop, Salamouris explains. We use that information to drive not only the apps but encoders, switchers, and more, so, when we make changes, they have to propagate to all of those different applications.
The OBS Broadcast Data Feed area continues to expand within the IBC as data becomes more central to all Olympic activities.
What happened this week with the alpine events exemplifies the powerful role that data and metadata feeds play within Olympic operations. And it is one of the reasons the Broadcast Data Feed (BDF) technical area in the International Broadcast Center (IBC) continues to expand in size and scope. Data powers everything, from graphics creation to archiving and then for broadcasters to more easily find the most relevant content for their needs both at the Games and in the years to come.
The BDF is more prominent in our operations, Salamouris says. It's not just audio and video but data and metadata that are part of the product delivered to the broadcasters. It has all of the details about the sports: the results, the start lists, the logs, bios, and everything we know about the Games.
A Prefab IBC
At the center of the Olympics production efforts is an IBC that measures 36,000 sq. meters, and according to Salamouris, as of last week, every square meter had been snatched up by a rightsholder. The facility is home to the production efforts for not only OBS, which creates the host feeds for all the events, but nearly four dozen rightsholders.
More than 45 Olympic rightsholders are calling the IBC home for the Winter Olympics.
It is from the IBC that OBS will deliver more than 5,000 total hours of coverage, including 850 hours of live coverage from PyeongChang. It will take a team of more than 4,000 to create that content and deliver it to rightsholders via 20 HD multilateral feeds (all with discrete surround-sound and stereo audio), seven UHD multilateral feeds, and nine multiclip feeds that feature highlights, press conferences, and more.
In addition, more than 7,000 accredited rightsholder personnel from 67 countries are onsite in PyeongChang. Forty-five of the rightsholder organizations have a presence in the IBC, the largest of which are NBC and, new this year, Eurosport.
The 2018 Olympics marks the second Games where OBS has used a fully modular and prebuilt building for the IBC, ending the need to build one from scratch. Salamouris explains that it not only allows OBS to amortize the costs of the building over a few Games but also meets the growing need for organizations to be more environmentally friendly and sustainable. The IBC walls, floors, and other physical structures are shipped in about 300 sea containers, with an additional 80 for the core technical infrastructure that powers the IBC.
And, although there is plenty of talk about rightsholders' keeping production teams home, there are still plenty of personnel and facilities onsite.
Eurosport's Cube studio, which allows talent to be placed in an AR environment, is part of the broadcaster''s new presence in the IBC.
The IBC not only is home to the operations for those rightsholders but also provides a massive technical hub for OBS. More than 900 km of cable tie everything together and allow the optimal exchange of content between OBS and the rightsholders.
New Tenants
One big change in the IBC is a new face on the landscape: Eurosport, which snagged the rights for all of Europe and is transforming the way Olympics content is being delivered across the continent. Previously, Eurovision was the main gatekeeper for Olympics broadcast rights across Europe, but it was primarily a member-based organization. Eurosport's presence is different in that it is s single broadcaster with its own commercial objectives and also a large number of sublicensees, such as ARD/ZDF, the BBC, ORF, and RAI. Eurosport's presence in the IBC, for example, includes separate control rooms to enable countries like Sweden and Norway to deliver more-nation-specific coverage.
It's nice and exciting to have Eurosport here, says Salamouris. [It comes] with new ideas that are refreshing because they deal with more digitally driven broadcasting.
