Six cool innovations to help viewers understand games in a new way


Each Olympics offers the Olympic Broadcasting Services (OBS) team the opportunity to take advantage of new technologies and give production teams new storytelling tools that can help viewers better understand various sports. The Tokyo Games are no different. Here are some of the top innovations to look for:

Hollywood-style reruns will be part of the summer games action thanks to multi-camera reruns.

Or: 3 × 3 Basketball, Gymnastics, Athletics Athletics, Cycling BMX Freestyle and Racing, Golf (Hole 14 Tee), Women’s Football Final, Street Skateboard, Sport Climbing, Volleyball
Multi-camera replay systems will help provide replays of the action from multiple angles, allowing fans to watch the action up close, from different angles, and experience the summer Olympic action like never before.

How it works?
Relying on a myriad of high-speed 4K cameras, Multi-Cam Replay technology offers the ability to move through the action at any given moment and watch it from different angles, in near real time. In addition, the replay can be interrupted at different times during the movement. The effect is similar to action scenes from “The Matrix” where the camera appears to rotate 360 ​​degrees around the lead actor while floating in the air or dodging a bullet. At some sites, between 60 and 80 4K cameras will be placed at selected locations for optimal unobstructed viewing. Spaced at regular intervals on a platform structure, each camera is mounted on a robotic platform capable of accurately moving and tilting the camera in any direction. The platform’s zoom, focus, and pan and tilt capabilities are controlled from the production unit. For each replay, a single operator selects the point where motion is frozen and can manipulate the replay side-to-side around the athlete, as well as zooming in without losing resolution (thanks to 4K resolution). Since the system simply puts these streams together and does not have to virtually create fill frames, no rendering is required, allowing Multi-Cam Replay clips to be ready in less than five seconds.

2D image tracking will make it easier to track athlete positions on a course.

What: 2D image tracking
Or: Track and field marathon and race walks, Road cycling and mountain biking, Water marathon Swimming, Triathlon, Canoe Sprint, Rowing
As part of a new innovation for the Tokyo 2020 Games, OBS will provide more information than ever on selected sports / disciplines using video tracking technology to help commentators and viewers follow the position of athletes throughout. throughout the event in real time. .
How it works?
Compared to other live athlete tracking solutions that rely on GPS positioning or wireless equipment, 2D image tracking is based on advanced image processing technology that enables motion tracking. A ‘patch’ (a square) is defined on selected video images in order to identify each of the athletes / boats. The computer then creates a “tag” which is attached to each of the identified athletes / boats and which will be retained even if the image changes. This captured data is then made available to a graphics rendering platform for on-screen presentation to viewers, allowing them to know the exact location of the athletes / groups / boats. Additional data captured using more traditional GPS positioning can be combined with “tags” to identify athletes, their speed, distance to go, or relative position to the leader.

Intel and Alibaba are working together to bring 3D athlete tracking to the Tokyo Games.

What: 3D Athlete Tracking (3DAT)
Or: Athletics 100m (incl. Decathlon), 200m (incl. Heptathlon), 400m (incl. Decathlon), 4x100m relay
Developed by TOP Global Sponsors Intel and Alibaba, New AI-Based 3D Athlete Tracking Technology (3DAT) is a one-of-a-kind broadcast enhancement technology using artificial intelligence and computer vision to enhance the viewing experience with near real-time information. and superimposed visualizations during athletics sprint events (100m, 200m, 400m, 4x100m relays, as well as Decathlon / Heptathlon).

It will provide an overview of a race’s results and the performance and comparison of Olympic athletes. Broadcasters will receive next-generation graphics showing a broadcast overlay visualization of the race with each runner’s sprint speed at certain points in the race and additional race data. It will offer a more in-depth post-race analysis and reveal an additional layer that was not evident during the race itself. For example, viewers will be able to understand exactly when each sprinter reached their top speed and analyze the different phases of the race in detail through a colorful visualization of speed changes.

How it works?
Four on-site pan and tilt cameras will be installed at the Olympic Stadium to capture live performance of sprint athletes. 3DAT technology relies on massive computing power capable of processing large data sets. Using the speed of Intel processors (hosted on Intel-based data centers in Alibaba’s cloud infrastructure), OBS will be able to deliver this new analytical data as part of the multilateral flow in a rapid turnaround time. .

Panasonic contributes to the collection of biometric data for archery at the Olympic Games.

What: Viewing biometric data
Or: Archery
Have you ever wondered what happens inside an archer’s body when he’s at full draw, shooting for a medal, with no movement visible in his body? Now you can find out because, for the first time at the Olympics, RHB will be able to take their archery coverage to the next level and reveal the inner workings of Olympic archers by displaying biometric data. Together with global partner TOP Panasonic, OBS will leverage non-contact vital sensing technology to provide live heart rate monitoring.

How it works?
Four cameras will be placed approximately 12m from the athletes, focusing on their faces and analyzing the slight changes in skin color generated by the contraction of blood vessels in the captured video. The audience will be able to witness the variations in heart rate and the adrenaline rush felt by the archer’s body, as he shoots his arrow, through an on-screen graphic.

Intel True View will be used for all Olympic basketball games.

What: TrueView 360 video
Or: Basketball
Using True View technology from global TOP partner Intel, OBS will for the first time offer immersive replays for all basketball games. TrueView creates 360 ° three-dimensional (3D) video using a set of cameras mounted high up in a stadium or arena.
How it works: In Tokyo, a total of 35 4K cameras will be mounted at the lobby level of the Saitama Super Arena to capture volumetric video that, when processed, will deliver 360 ° reruns, bird’s-eye views, great stops on picture and fascinating stories from any perspective on the search. OBS will produce up to 10 True View clips for each basketball game.

3D models will help viewers better understand sport climbing.

What: Virtual 3D graphics
Or: Sport climbing
Making its Olympic debut at Tokyo 2020, sport climbing takes the challenge of climbing steep climbs to a whole new level. Using a range of hand and foot grips in different shapes and sizes, climbers practice their skills and strength on a wall measuring either 15m in height (Speed ​​and lead) or 20m in width (Boulder). To help the public understand the challenges faced by athletes and understand how they solve problems, innovative computer-generated graphics will enrich the coverage of this new Olympic sport.
How it works: OBS will create a 3D representation of the wedges and walls, creating a virtual world that feels more real than what a camera could capture. This 3D model allows for a detailed analysis of the angles and holds of the wall and gives viewers a glimpse of what it can feel like to face the ever-changing challenges on the walls. Augmented Reality (AR) technology will be used to switch between (real) camera shots and this virtual world at any given time, as well as to generate virtual data on shots, varying angles of the wall and routes. In this virtual world, you can zoom in at any time, with a very close-up on a small detail of the hold, while zooming out to appreciate the wall in its entirety. 3D virtual graphics technology will provide commentators with access to a huge amount of analytical data, allowing them to explain to their viewers what goes on in the minds of athletes as they progress on the walls.
