Once just a vision captured by artist renderings, the main video board at SoFi Stadium is now a stunning reality, showing what’s possible when you combine a powerful idea with the technology, construction expertise and the will to make it so.

While fans will have to wait for the pandemic to subside before they can fully enjoy its attributes, like its full 4K resolution, the 120-yards long double-sided oval videoboard from Samsung – which is as tall as four stories high at its largest points – has been providing “wow” moments all fall to TV audiences who get glimpses on-screen of the board in action. But take their word for it, those who have seen it in person are generally in awe.

“It’s absolutely fascinating – I’ve never seen anything like it,” said Skarpi Hedinsson, chief technology officer for SoFi Stadium and Hollywood Park. The stadium is home to two NFL teams, the Los Angeles Rams and the Los Angeles Chargers. Early this fall at a team scrimmage, the board was lit up and Hedinsson walked all around the stadium for looks from as many vantage points as possible, and came away stunned.

“It’s everything we had hoped for,” Hedinsson said. “It’s exactly what it was designed to do.”

Vision of Kroenke

When the idea of what would become SoFi Stadium was being developed, several sources we talked to pointed to Rams Owner/Chairman and SoFi Stadium and Hollywood Park developer Stan Kroenke as the visionary for a videoboard that had never been done before.

“I have to give full credit to Mr. Kroenke for the vision,” said Hedinsson. “He sat down with HKS, our architects, and asked what was the ‘art of the possible.’ It was all part of how to innovate for the guest experience, and how to approach it.”

The evolution of videoboards in large NFL-type venues has become an interesting trend to watch, with highlights along the way including the massive centerhung screen at the Dallas Cowboys’ home, AT&T Stadium, and the circular “Halo Board” that sits below the outside edges of the camera shutter-like closable roof at the Atlanta Falcons’ Mercedes-Benz Stadium.

At SoFi Stadium (and the adjacent Hollywood Park), where various reports estimate that Kroenke has spent somewhere north of $5 billion in development costs, the needle of innovation has now been moved in a much different direction. Originally nicknamed the “Oculus” (a term no longer used by the stadium) the double-sided oval board hangs from the stadium’s cable-supported roof in a manner designed to present a clear video view to any seat in the house, from the field-level seats all the way up to the highest decks. Capacity for SoFi Stadium is estimated at approximately 70,000 for NFL games, and up to 100,000 for special events, like the Super Bowl.

So what are the stats?

According to figures provided by SoFi Stadium and by Samsung, the videoboard sits 122 feet above the playing field and 70 feet below the roof canopy; at 120 yards it is longer than the field of play, and it is also wider than the field. According to Samsung, its outdoor LED products were used exclusively to build the 70,000 square-foot dual-sided screen, which contains nearly 80 million pixels at a spacing distance of 8 millimeters from center to center.

The board is not symmetrical in shape for a reason: According to Samsung, the different sizes are part of the strategy of making the board visible to all seats in the venue. Mark Quiroz, Samsung’s vice president for sales, marketing and business development, said the company did virtual simulations of the screen’s visibility angles to all the seating sections to help determine the best final shape.

“It was all about getting the best views for the fans,” Quiroz said of the virtual testing.

At its tallest points, the board’s largest panel is approximately 40 feet tall; at the smallest points it is approximately 20 feet tall. According to Samsung, fans seated in the lower bowl will view the inside of the videoboard, while fans in the upper bowl areas will view the outer panels of the videoboard.

According to SoFi Stadium, the videoboard not only features the most LEDs ever used in a sports or entertainment venue, but it also has the first 4K end-to-end video production in a stadium, one that has 12 Gbps connections between cameras to ensure enough band- width for the higher-resolution content. The videoboard also has a JBL audio system that is home to more than 260 of the stadium’s approximately 4,500 loudspeakers.

According to Hedinsson, the videoboard will also eventually house 5G cellular antennas, since the location of the board gives it a perfect line-of-sight mounting position for the seating bowl.

If Hedinsson’s initial impression is correct, it would seem that all the partners involved in the board’s construction and deployment nailed Kroenke’s original vision, and made it come to life. But it was far from an easy task.

How to build ‘the art of the possible’

According to Hedinsson, the uniqueness of the videoboard and its structural size dictated that all design had to start by thinking about the board first.

“It [the videoboard] needed to be part of the earliest discussions – you have to design around an idea like that,” Hedinsson said. Since the 2.2-million-pound board would rely on the stadium’s cable-net roof for support, it was both one of the first structures to be designed, and one of the last to be put in place. The board was actually assembled on the ground inside the venue, and then hoisted into place after the roof was built.

According to Samsung’s Quiroz, the final installation of the board involved a lot more than just pulling on some cables.

“The most challenging aspect [of the construction] was the tolerance levels in the seams,” said Quiroz, talking about the tightness needed to keep screens close together so that the video output does not have any visible breaks.

“Getting the seams right on the ground was one thing, and then keeping it together until you get it in the final resting place was another major challenge,” Quiroz said.

As if the construction team needed any more difficulty, during the final months of building the project had to deal with the onset of the Covid-19 pandemic. While admitting that Covid was “kind of a cloud that loomed over everything,” Quiroz said that since the overall project was a closed situation in a fairly large space made it somewhat easier to deal with safety requirements like social distancing.

Using the new canvas

When fans finally are allowed in the venue, the final chapter of the SoFi Stadium videoboard will be written – or, more accurately, shown in 4K resolution, as game information and sponsor messages make use of the one-of-a-kind screenscape. With the circular shape, all the potential providers of content – from the teams to the potential sponsors – seem excited about the possibilities.

“With the custom shape, there are probably things that still need to be developed,” said Samsung’s Quiroz, about the need for new design tools and new ways of thinking about what types of content might be possible. “We provided the template, so now it’s all about how you can use the capacity.”

According to Hedinsson, the SoFi tenant teams – both the Rams and the Chargers – have actively been working on building content for the board since December of 2019. With various “modes” available for display
– including full 360-degree perspectives and “full takeover,” where the Ross Video and Cisco Vision display management systems in tandem will allow a single message across not just the video board but over all the 2,000-plus smaller displays in the venue – Hedinsson is looking forward to times when the video board fulfills its promise of being able to amplify the atmosphere.

“The teams have really embraced [the board’s possibilities],” Hedinsson said. “We’re going to see some really interesting uses of the space.”

Converged innovation: SoFi Stadium’s networks break new ground

When you spend more than $5 billion building a revolutionary-looking new sports and entertainment venue, it’s a good bet that the technology found inside is the best that can be found.

What’s truly innovative at the new SoFi Stadium in Los Angeles is not just the quality and functionality of the technology’s pieces and parts, but also the venue’s embrace of a converged network design, where all network-attached devices connect to a single Cisco Catalyst-based network.

Led by Skarpi Hedinsson, chief technology officer, SoFi Stadium and Hollywood Park, and master technology integrator AmpThink, the networking and compute environment deployed inside the building (as well as in Hollywood Park’s neighboring retail, commercial and residential area) is unlike most large venues, where different systems typically exist in their own silos, often with their own separate and different network.

Instead, the SoFi Stadium network brings all building functionality – including the wireless networks (among the largest built anywhere), the server compute platform, the telephone system, the IPTV network, the indoor and outdoor digital signage (including the massive oval dual-sided 4K main videoboard), the television broadcast systems, and the building management systems – into one converged platform, with a single vendor/single format structure.

“What we delivered is a scalable platform that simplifies Day 2 operations on Day 1,” said AmpThink president Bill Anderson.

Over the coming months, Stadium Tech Report plans to do deep technical dives on each segment of the stadium’s different technology deployments. Consider this story a sort of “executive summary” that will attempt to at the very least introduce all the technology elements that are part of the stunning new venue, which hosted its first NFL games for both stadium tenants, the Los Angeles Rams and the Los Angeles Chargers, in early September.

Converged network a revolution for stadiums

If the stunning architecture of SoFi Stadium and its innovative elements like the oval, dual-sided videoboard represent the realization of Rams owner and Hollywood Park developer Stan Kroenke’s “art of the possible,” then the converged network and its interlocking technologies perhaps represent “the art of the practical,” at a scale somewhat unprecedented inside a large public venue.

If you poke your head inside older sports venues, you are most likely to see separate networks and operation centers for many of the different systems – wireless, wired networks, broadcast, and building operations. Historically the case has been made that those who know those systems best are responsible for building their operations – but the silo approach often brings headaches to those in charge of overall operations for the venue as a whole, as they deal with the proliferation of different systems to operate and manage.

AmpThink, which has deployed networks in more than 70 venues across the country, pioneered the idea of a single, converged stadium network when it built the prototype at the 14,000-seat Dickies Arena last year. But the size and scope of the converged network project at SoFi Stadium – which will hold 70,000 fans for NFL games and up to 100,000 for special events like the Super Bowl – was much larger. Still, according to AmpThink’s Anderson, the planned outcome was the same: to deliver the best outcome for the customer.

“It all works together, because it’s designed to work together,” said Anderson. “Instead of fighting to see if one switch works with another, you can focus on the business.”

With 120 separate remote telecommunications rooms – including some hardened for hot weather conditions in the outside areas of Hollywood Park – the SoFi Stadium converged network is designed to present a “single pane of glass” management structure, where there are no “islands” requiring special attention.

Even the live video production system, usually a completely separate entity, is run on a connected Cisco Nexus switched environment. Every telecommunications closet or cabinet is directly connected via fiber to the campus core. According to AmpThink, all the telecom rooms have edge switches that use 25 Gbps optics and a minimum of two connections per closet/cabinet to provide an aggregate of 50 Gbps of campus interconnectivity.

The blanket of Wi-Fi and cellular coverage

On the Wi-Fi side, the SoFi Stadium network is the biggest AmpThink has built in a stadium, with approximately 2,400 APs inside the venue and another 300 in the surrounding Hollywood Park area. For the full Wi-Fi 6 Cisco deployment, AmpThink used an under-seat deployment in the main bowl. Before expanding to include full stadium technology integration, AmpThink made its name in successful big-venue Wi-Fi network design and deployment, with networks built most recently at Mercedes-Benz Stadium in Atlanta, and last year at Ohio State and Oklahoma University, the first two large-stadium networks to move exclusively to the new Wi-Fi 6 standard.

In a commitment to offering the best possible connectivity to consumer devices no matter which network they use, the Wi-Fi and cellular distributed antenna system (DAS) at SoFi Stadium were both designed to each provide 100 percent venue coverage. The DAS, designed and deployed by DAS Group Professionals using gear from JMA Wireless, is the largest ever deployed. According to Hedinsson, the network has 2,400 antennas and 3,200 remotes, and is capable of covering all licensed spectrum bands between 600 MHz to 6 GHz.

As cellular carriers move toward the 5G future, the DAS is capable of supporting all the low- and mid-band spectrum currently planned for use. According to Hedinsson, there will also be millimeter-wave 5G services in the stadium, from a carrier to be named later. The stadium networks are supported by 50 Gbps backbone links.

Bringing data center strategies to the stadium

While hyper-convergence of server use is common in the data center space, that has traditionally not been the case in sports and entertainment venue operations. But the eventual compute network built for SoFi Stadium’s operations even surprised AmpThink’s Anderson, whose company originally estimated a compute environment with perhaps 20 to 30 virtual machines.

As it stands now, Anderson said the compute environment has almost 100 VMs, which host applications for all the network operations as well as varied building management needs like power, light, HVAC, security, and even specialized systems like irrigation and seismic monitoring. Instead of a mix of servers running siloed applications on separate physical machines with different operating systems, the SoFi Stadium compute environment is a unified platform and includes a seamless integration into Google Cloud, allowing it to be easily scaled to meet current and future needs.

A digital stadium with displays big and small

Any discussion of digital displays at SoFi Stadium has to start with the main videoboard, a one-of-a-kind design of a 120-foot long oval that circles the playing field, with dual-sided 4K screens, some 40 feet in height. (Please see our detailed profile of the main videoboard in our recent Venue Display Report.)

The digital display footprint goes far beyond the main screen, with some 2,600 other smaller boards deployed throughout the venue and in Hollywood Park. According to Hedinsson, the ability of the Cisco Vision display management system is a key part of the “digital stadium” design, especially when you consider that the venue has two main tenants, each with their own branding and look and feel.

“Being digital means we can switch over the branding [by changing displays] instead of physically having to move signs,” said Hedinsson. “That’s why we have Cisco Vision. We have digital ‘playbooks’ for the different scenarios, and we can just push them out as needed.”

Warriors go ‘biggest’ with Chase Center digital displays

With a once-in-a-lifetime chance to build the best basketball arena around, the Golden State Warriors went all in on digital displays at Chase Center, installing the NBA’s largest video board while putting in more pixels overall than any other arena in the league.

The the star of the show is the centerhung video board, a mammoth 9,699-square-foot display from Samsung’s Prismview with 15 separate boards, including ones underneath so the courtside fans don’t have to crane their necks too far upward. While the so-called “chandelier” dominates the view inside the Warriors’ new home, one hint that the Warriors are getting display restraint right is the fact that the board can be completely hidden if so desired, sucked up into a hiding hole in the ceiling. The hide-the-scoreboard trick seems to be proof that the Warriors care enough about the venue experience if it means they have to stow away their favorite toy every now and then.

In a mid-October 2019 visit to Chase Center, Mobile Sports Report can tell you that there is no missing the video displays inside the new $1.4 billion arena, which opened in September 2019 in San Francisco, just south of the San Francisco Giants’ Oracle Park alongside the San Francisco Bay. With 64 different video boards in total, which according to Samsung includes 53.6 million individual pixels – as well as another 1,100 Samsung LCD TV screens – Chase Center is as digitally visual as can be, with (according to the Warriors) 40 percent more display screen area than any other comparable-size venue.

The most pixels inside

Editor’s note: This profile is from our recent Venue Display Report, which you can view in its entirety online, with embedded videos and much better photography! You can also read about Chase Center’s wireless networking in our recent Stadium Tech Report, also available for instant online reading! When it comes to technology at Chase Center, there is no better in-depth resource than Mobile Sports Report!

The display deployment actually starts outside Chase Center, where at the western entry there sits a 74-foot by 42-foot screen that welcomes fans to the arena. The outdoor video board, according to the Warriors the only live video screen in the city, faces an interesting bit of architecture, a stand of steps that will serve as a de facto outdoor gathering space, a feature many stadiums are incorporating lately. Just inside that entryway sits another visual treat, a wide high-definition (1.5mm pitch) video board that provides instant connection to whatever event is taking place, whether it be a Warriors game or a concert.

Inside the main bowl, the centerhung video board dominates all views, with its incredibly crisp (6.7mm pixel pitch) main screens. While all the numbers can be staggering, according to Warriors president and COO Rick Welts, the team didn’t install the biggest and brightest displays simply to win some kind of imaginary tech title.

Instead, he claims, it’s all about creating the best possible fan experience for a following that represents a unique confluence of events, namely the economic success of Silicon Valley and the recent run of NBA championships by the Warriors.

Keeping the focus on the game, or the event

“There’s no doubt we are in an arms race (in regards to stadium technology) but we didn’t want to let that drive us,” said Welts, who was our guide for a media tour of Chase Center in October. But it’s also worthwhile to note that there are probably less than a handful of other professional or college teams who could currently match the Warriors’ unique combination of a rabid fan base with immense amounts of disposable income.

In a day and age when most new venues are built with at least some kind of public tax money, the Warriors’ new $1.4 billion home was entirely privately financed, helped along by things like the new courtside premium suites, which come with their own wine locker and wine butler, and cost around $2 million per year, according to Welts.

Upper-deck seating has an extra LED board to provide more stats

“It’s just what you can do when you combine the hottest economic model in the world [in Silicon Valley] with an amazing team,” said Welts, who noted that the courtside suites all sold out. “I would not recommend this format for most teams.”

But even with more blinking lights than any other facility, the Warriors seem very conscious about not making the venue seem like the Las Vegas strip, or New York’s Times Square. Instead, the team wants to make sure that all its digital-board messaging contributes to the moment, whether that moment is a Warriors’ game or a concert or some other type of show.

“The trick is to strike a balance, between commercial content and Warriors content,” said Mike Kitts, the Warriors’ senior vice president for partnerships. According to Kitts, the Warriors are working with sponsor partners to create digital messages that are at least what he calls “Warrior-esque” – such as combining some kind of basketball theme to advertising messages.

“You want something that feels authentic to the moment,” Kitts said.

Feeding the content beast with things fans want

When the San Francisco Giants installed a new huge video board at Oracle Park this past season, the Giants’ team had an interesting problem in deciding what kind of information to include on all the new space.

Similarly, the Warriors’ expansive digital canvas gives the team the ability to indulge the geekiest of hoops junkies with incredibly specific information – while also trying not to overwhelm the average fan.

“What we want to do is provide all the things that fans say, ‘I want.’ “ Kitts said. At a preseason game against the Los Angeles Lakers the Chase Center screens not only provided the regular kind of statistical information (shots made and missed) for players on the court, they also had some changing screens that could do tricks like show exactly where on the court a player just made a shot from – and what that player’s “heat check” stats were for all shots taken so far that game.

Can you see me? The centerhung video board can disappear into the rafters as needed

“We are continually programming [the displays],” said Paul Hawkins, the executive producer of the Warriors’ in-house content team, called Warriors Studio. “It’s a huge challenge for us as content creators to make this come to life.”

To that end, the Warriors have assembled what is probably also the largest team of content creators and programmers. With 23 full-time employees and another 15 part-time contributors (“and that doesn’t count the freelancers”), the Warriors think they may have the NBA’s biggest in-house content creation team, though they say the Miami Heat may have just as many.

If that seems like an excessive number, remember the stats from the start of the story – with 64 different LED boards, the math to make a single sponsor’s message fit all the different screen dimensions for an arena-wide “moment of exclusivity” is a much different challenge at Chase Center than at other arenas.

And even while back in October the content team admitted it was still “not perfect yet” at dialing in its on-screen workflows, from attending both a Phil Collins concert and the Warriors game on back-to-back nights, MSR can attest that the ability to change looks and feels based on what’s on (or not on) the digital displays can significantly improve the attendee experience – including not seeing the huge centerhung display at all when we sat and listened to Phil Collins and his band playing all the hits from the musician’s vast historical library.

From our limited exposure, we still think the Golden State Warriors did what they wanted to at Chase Center when it comes to digital displays: They used the biggest and best technology, but did it in a way where the technology isn’t the star – but the experience it allows is.
