NEW YORK — When it comes to using cutting-edge broadcast technology to cover the 2018 PGA Tour, CBS Sports is going all-out to provide unique, insightful shoots of what’s happening on the course.

“Our philosophy is to use advanced technology to tell the story,” said Harold Bryant, CBS Sports’ executive producer/and senior vice president of production. “We also use it to teach the average golfer to improve their own game.” CBS Sports deploys this technology at various PGA Tour events, working out of the SSCBS mobile production unit equipped and operated by NEP.

SHOT TRACKING

It isn’t always easy for viewers to understand what’s happening on the fairways and the greens; especially when it comes to the shots being taken by golfers and how they play out.

To explain the process, CBS Sports uses Toptracer’s real-time ball tracking (“tracing”) system, which graphically portrays the ball’s trajectory, arc, and apex as it travels from golf club to ground.

CBS Sports has been using Toptracer onscreen for eight years, and has been enhancing its application for PGA coverage ever since.

Most recently, CBS combined Toptracer with ARL’s Virtual Eye technology and “ShotLink” shot-by-shot analytical data provided by the PGA Tour, to track the ball’s progress from an actual camera shot as well as via second-view animation showing it “flying over” the golf course. The second animated view — which is on the right side of the broadcast screen — includes ball speed, distance, and apex graphics on the screen in real-time.

“The animation looks so good, you can hardly tell the difference between it and the actual camera shot,” said Ken Aagaard, CBS Sports’ executive vice president, Innovation and New Technology.

READING THE GREEN

Every time a player approaches the cup, armchair golfers at home like to guess how they should putt the ball on the green.

CBS Sports hopes to help lessen the guesswork with “Green Reader” graphics software from Hawkeye (a Sony company). Green Reader is preloaded with a topographic 3D map of each green, and has the ability to calculate and display an onscreen “cone” showing the sweet spot for hitting the putt right. The network is currently experimenting with the technology.

“If you’re hitting it within this cone, there’s a good chance that you’re going to be in the hole or near the cup,” said Bryant. The only drawback for golfers is that they don’t have this graphic to refer to on the green. That advantage rests with CBS Sports’ viewers.

SLOWING DOWN WITH SWINGVISION

Since 2006, CBS Sports has been using high frame rate cameras to cover the shots in slow motion so that viewers can see for themselves how a golfer’s swing actually progressed. The feature — known as SwingVision — has won an Emmy.

Typically, high-frame-rate cameras have operated at 4x real-time speed; shooting 120 frames per second vs. the standard 30fps used for broadcast.

But this wasn’t good enough for CBS Sports, which introduced a Sony 4800 16x960 fps camera at the June 2018 FedEx Cup that raised the frame rate to 16 times real-time speed, according to Aagaard. “Peter Kostis is really a whiz at describing a player’s swing, and when you see that swing using a high-frame-rate camera on SwingVision, you can see how accurate he is,” he said.

DON’T FORGET ON-COURSE TALENT

When it comes to on-course coverage from field reporters, the days of talent standing alone with their microphones are over; at least for CBS Sports and their PGA Tour coverage. When CBS Sports Reporter Amanda Balionis does live hits on the course, she has access to a 72-inch touchscreen computer mounted on a mobile golf cart known as the “SmartCart.” Like a TV studio meteorologist, Balionis can call up graphics, stats and footage on the fly.

“SmartCart makes you feel like you’re closer to the action,” said Bryant. “You can use it on site to call up golf swings and shot live to air — and then drive the cart to the next hole to keep up with the action.” CBS is the first U.S. broadcast network to use SmartCart, which it debuted in 2016.

4K/HDR, DRONES AND ATMOS

To cover golf in 4K/HDR for DirecTV’s 4K subscriber service, CBS Sports uses Sony HDC-4300 4K-capable cameras from the SSCBS mobile truck in 4K mode, giving the network valuable experience in using the technology.

Aagaard is more impressed with HDR than 4K.

“You can’t tell much of a difference between 1080p and 4K on side-by-side monitors,” he said. “But the enhanced color range of HDR really stands out; especially shooting in bright sunlight where SDR would provide washed-out images, but HDR shows a full range of shade and light levels.”

CBS Sports is also shooting pre-broadcast overhead shots using drones. “We don’t do this when there are people on the course,” Aagaard said.

As for audio, the network will begin testing Dolby’s Atmos “3D” audio capture system next month. “We were testing HDR two years ago, to stay ahead of the curve,” Aagaard said. “Same thing with Atmos; when it becomes popular with consumers, we’ll be ready.”

CHURCHILL DOWNS, Ky.—The 144th running of the Kentucky Derby on May 5 was the wettest derby in the event’s history. By the time the field of three year-old thoroughbreds (including race winner Justify) thundered down the legendary Churchill Downs track, more than 2.8 inches of rain had fallen at nearby Louisville Airport, breaking the previous Louisville May 5th rainfall record of 2.31 inches, which had stood since 1918.

For NBC Sports, whose Kentucky Derby coverage capped three days of horse racing on NBC and NBCSN, the working conditions were extremely difficult. The relentless heavy rain turned the Churchill Downs track into muddy, sloppy muck that splashed skywards wherever the horses ran (sheets of mud spray can be seen in the Derby race video) while drenching crews and equipment. Granted, NBC Sports had weatherproofed cameras and operator positions before the race, but the rain still made life tough for personnel to work outside.

“Just to try to keep 52 cameras up in rainy weather that continued all day was a feat in itself.” —John Roche, NEP

“It was a miserable, miserable day, all day,” said John Roche, senior technical manager for NEP, which provided the mobile units and related equipment to NBC. “Just to try to keep 52 cameras up in rainy weather that continued all day was a feat in itself.”

Despite the damp weather, NBC Sports was able to break new ground with a never-before seen camera angle on the track’s distance back stretch, thanks to “BatCam.” “It was a true innovation at the derby,” said Tim DeKime, vice president of sports operations for NBC Sports.

FROM NASCAR TO REAL HORSE POWER

Initially used by NBC Sports to cover high-speed NASCAR races, BatCam is a cable -supported, self-powered moving Panasonic AK-HC1500G HD box camera that goes from 0 to 60 mph in 1.5 seconds; reaching speeds in excess of 100 mph. BatCam’s combination of quick acceleration, high speed, and unobstructed suspended camera angle made it well-suited to cover Churchill Downs’ back stretch. (Top horse speeds at the derby typically hover around the 40 mph mark.)

The decision to use BatCam came after long discussions between NBC Sports and Churchill Downs managers. “Our producers’ desire was to get a different shot of the back stretch that we’ve not seen before,” said DeKime. Eventually, everyone opted for the high-speed BatCam after considering “various types of camera systems,” because none of the others were fast enough to keep up with the horses while providing consistent, smooth video.

To use BatCam at the Kentucky Derby, two 80-foot reticulated arm lift trucks with 10-foot extension trusses were positioned inside the track’s second and third turns respectively. Next, a high-tension cable measuring 2,200 feet was suspended between them at a height of 90 feet above ground. BatCam — with its remotely-controlled Panasonic AK-HC1500G HD “camera car” unit — was then mounted on the cable.

The result was a smooth, extremely clear overhead camera view of the Churchill Downs’ back stretch from end to end. (It can be seen in this NBC Sports clip of the race.)

“You could see the race from a spectator’s point of view,” said Roche. “You were travelling side-by-side with the horses as they ran along the back stretch.”

CAMERAS & OTHER CONSIDERATIONS

In addition to BatCam, NBC Sports had 52 HD cameras positioned around the Churchill Downs course. “We used 27 Sony HDC-2500 cameras — including six handhelds connected wirelessly by BSI RF equipment — eight HDC-4300s, and one HDC-4800 4K camera for the finish line,” said Keith Kice, NBC Sports’ senior technical manager. “We ran the 4800 at four times speed and were able to do the digital zoom on the camera [to take a closer look at the finishers while delivering 1080p video resolution].”

For the Kentucky Derby — which averaged 15 million viewers this year — NBC Sports thought it worthwhile to add a 4K camera to the production.

“If our budget has the room, we use 4K where we can,” said DeKime. “4K lends itself to the finish line camera, and we’ll use it on various other horse races. If the Belmont becomes a Triple Crown contender, I can promise you that we’ll have 4K on the finish line as well.” [This issue went to press prior to the race.] He noted that the Sony HDC-4300s can be upgraded to 4K if required, allowing NBC Sports to scale up 4K resolution if need be.

As for the mobile production trucks NBC Sports used NEP’s ND1s A, B, C and D units for the main NBC network show, according to Kice. “Earlier in the day, when we were on NBCSN, we used NEP’s SS-15. We also had a mobile unit there from BSI that provided all of our RF audio and video for the show.”

Laying out all 52 cameras, and connecting them back to the production trucks (by fiber-optic cable or RF), was a major challenge for NBC Sports due to Churchill Downs’ sheer size. “It’s about a mile around,” Kice said. “Getting everything in place, connected, and checked out on schedule made for a very full three days.”

Despite all the factors NBC Sports had to deal with, everything went as planned for derby fans.

“The weather was pretty horrible, and it put a damper on everything; no pun intended,” said DeKime. “But for as much rain as we got, during what was probably the wettest Kentucky Derby ever, we had very few problems. One of the cables got fried due to water near the end of the day, but overall it was technically a pretty good day for everybody despite the circumstances.”
