I wrote a posting on TV broadcasting in Rio Olympics. This posting continues the same theme giving more technical details and links to where to see what the TV broadcasting technology looks at 2016 Summer Olympics. This blog article is a ombination of information from very many articles that tell on TV broadcasting at Rio Olympics. Having some experience on doing technology part in few live TV broadcasting some years ago, I was interested what kind of technology is used in this kind of huge TV broadcasting system. Over 5 billion people will watch the Rio 2016 Olympic Games from home on their TVs and internet devices.
Technical innovations and higher resolutions
Brave new world: Rio 2016 Games to showcase technological innovations article gives a quick look at some of the innovations making their debut in Brazil this August. Most of the innovations are for getting more accurate results from sports, but the article also mentions virtual reality, wearables and green technology. Technology at the Rio Olympics article picks Payments, Next generation streaming services and Monetization of sports data as most important. Rio 2016 – Digital Transformation for the Olympic Games video gives an overview to Technology Operations Center (TOC).
OBS Embraces Emerging Broadcast Technologies for the Rio Games article tells that the Rio 2016 Games, OBS will ultimately produce in High Definition and 5.1 Surround Sound more than 7,000 hours of coverage which will include live sport; the Opening and Closing Ceremonies; the Olympic News Channel; beauty cameras and other additional production material. The RHBs will bring these images to a potential TV audience of almost five billion people across more than 220 territories around the world. OBS broadcast coverage will be produced in 1080iHD. OBS will be working with Japanese RHB NHK to provide Broadcasters with live coverage of select Olympic events in 8K Super High Vision(7,680 x 4,320 pixels) (part of the UHD-2 standards) with 3-D 22.2 multichannel audio surround system. OBS will also provide coverage in 4K (part of the UHD-1 standards) of the same events which will be down-converted from the original 8K SHV. In addition to different resolutions, there are different frame rates used in USA and Europe. Frame rate conversions are needed by any content broadcaster or distributor dealing with international program feeds where content arrives at a different frame rate than that required for transmission or distribution to end users.
Rio 2016 Olympics Broadcasts: From 8K to VR to an iPhone article tells How and Where the Summer Games Are Being Streamed and Televised. Japanese public broadcaster NHK has already begun 4K and 8K UHD test broadcasts over its satellite channels. U.S. residents will have to make do with a 4K downconversion from the 8K footage captured by NHK and Olympic Broadcasting Services (OBS). NBC is offering at least one event per day in 4K UHD, distributing the footage to TV providers. NBC’s HDTV coverage will use broadcast equipment from Sony and Canon, including Sony’s HDC-4300 4K high-frame-rate camera system for HD replays, its PWS-4500 XAVC server, and its BVM-X300 OLED monitors. The glass is 2/3-inch 4K broadcast lenses from Canon.
2016 Rio Olympics will come in 4K after all: NBC to air the Games in UHD with HDR and Atmos sound article tells thatroadcaster will make content from the 2016 Summer Games in Rio de Janeiro available to carriers in not just 4K resolution but also with high dynamic range and Dolby Atmos sound.NBC is making 4K UHD HDR footage of the 2016 Games available via a 24 hour tape delay.These 4K replay sportscasts will be coming in 4K resolution thanks to NBC’s downscaling of native live 8K resolution recording footagebeing made of the 2016 Games by the Japanese state broadcaster NHK for the sake of the latter company’s continuing experimentation in live 8K public broadcasting in the time remaining before the 2020 Tokyo Summer Olympic Games.
Many different camera technologies
OBS Embraces Emerging Broadcast Technologies for the Rio Games article tells that the Host Broadcaster for the Olympic Games, Olympic Broadcasting Services (OBS) produces and distributes in many different resolutions. OBS will ultimately produce in High Definition and 5.1 Surround Sound more than 7,000 hours. In addition to that 8K Super High Vision and 4K are used. OBS will provide approximately 130 hours of live 8K SHV (7,680 x 4,320 pixels) coverage working with Japanese RHB NHK. OBS will also provide coverage in 4K (part of the UHD-1 standards: 3,840 x 2,160 pixel resolution) of the same events which will be down-converted from the original 8K SHV.
NBC Olympics Embraces HDR for Opening Ceremony Coverage article tells that Opening Ceremony is produced with 4K coverage in HDR with the help of a small six-camera flypack outfitted with Sony HDC-4300 cameras. That feed will be sent to the IBC via four 3-Gbps circuits operating in quad-link mode and then voiced-over at NBC’s production area in the IBC. The HDR feed will be shot in Sony’s sLog3 format, complete with BT.2020 color space and grading for 1,000 nits. The sLog3-2020 signal will be converted to ST2084-2020 with static metadata (commonly known as HDR10) and fed into HEVC encoders for transmission to the U.S.
To handle all the cameras, very many OB vans were needed. OB Vans Arrive in Rio article tells that there are 52 OB vans, 12 flyaway systems, seven independent audio production units and 31 support vans. This makes a total fleet of 83 vehicles and 19 production kits. Rio 2016 Olympics Broadcasts: From 8K to VR to an iPhone article tells that The World’s First 8K OB Vehicle Is in Rio. Ikegami is providing what it says is the world’s first 8K OB vehicle, which it delivered last fall, outfitted with 8K field cameras and supporting gear.

How the moving cameras get good picture when cameraman moves with them? Finnish magazine Tekniikan Maailma article Rion olympialaisia kuvataan yhä 70-luvun tv-tekniikalla tells that they use Steadicams. You might expect that camera stabilization represent state of the art electronics, but in reality it is a matter of pure mechanics of the 1970s - based on the hugely perfect balancing. Wikipedia says that Steadicam is a brand of camera stabilizer mount for motion picture cameras that mechanically isolates it from the operator’s movement. It allows for a smooth shot, even when moving quickly over an uneven surface. The Steadicam was invented by cameraman Garrett Brown and introduced in 1975.
The Rio Olympics will have some of the smartest sports cameras ever article tells that Getty Images, one of the largest wire services, and the official photo agency of the International Olympic Committee (IOC), will be using brand-new robotic technology developed by Mark Roberts Motion Control to extend the reach of their photographers at multiple venues for the 2016 Rio de Janeiro Games. Pros routinely wire cameras to arena rafters, the sidelines of playing fields and even underwater to cover as many angles of sporting events as possible.
Robot cameras snap splash shots in Rio article tells how a Getty photographer uses robotic cameras to get spectacular underwater images of swimmers at this year’s Summer Olympic Games.Getty photographers have used robotic cameras for years, typically to take shots from overhead and static cameras underwater, but now the underwater cameras can be remote controlled to different directions. The robotic camerasequipped with a Canon 1DX Mark II camera are attached to the floor of the pool using suction cups and operated from poolside using a remote control that resembles an Xbox video game controller. The photographers need to be are scuba trained.
Canon is heavily involved with digital cameras – they provide cameras and support for photo journalist. A very rare look inside Canon’s operations at the Rio 2016 Olympic Games tells that there is a Canon Professional Services to borrow equipment from them and gives view to CANON’S $6,000,000 STOCKPILE OF CAMERA GEAR FOR THE RIO OLYMPICS.
Cameras and camera links in the air
Blimp-Mounted Cameras Will Watch Everything That Happens At The Rio Olympics article tells that security personnel tasked with making sure athletes, attendees, and civilians are all safe during the event, that’s a sky-high task, so it helps that Brazil is going to have an all-seeing camera on a blimp record everything happening within an area of 15 square miles. The system is technically an aerostat, not a blimp, which means the inflatable sack of helium carrying the cameras is attached to a tether. That tether keeps it in one place, putting the “stationary” in “aerostat,”
The broadcasting system has used several cable cameras to get nic shots from the air. The was an unfortunate accident to one of them as 100kg ‘spidercam’ crashes into crowd in Rio Olympic Park, injures 7. Live From Rio 2016: Cable Camera Falls, Injures Seven; Investigation Ongoing article says that an aerial cable camera system operated by Olympic Broadcasting Services flying over the Barra Olympic Park fell to the ground near the entrance to Arena Carioca 2, causing minor injuries to seven spectators. At that time, according to the statement, the camera was 10 meters above the concourse and was supported by the two independent guide ropes, each of which able to support the full load of the camera, but both of them failed causing the camera to fall approximately 20 meters onto the lower concourse near the arena. The accident is documented in Overhead TV camera falls in Rio Olympic park, injures three video.
There are many events where there is need to have live picture from “on the road.” Wireless cameras play a big role in that. Live From Rio 2016: Road Races Rely on Next-Gen RF Technology article tells that to cover 241/137 km long cycling events at the 2016 Rio Olympics needed latest wireless camera technology. RF technology played a key role in covering the action as five motorbikes carried handheld-camera operators, two helicopters with RF cameras provided overhead shots, and two automobiles were also used – also hard cameras, handheld cameras, Steadicam units and crane cameras. The RF technologies have been improved since the 2014 Olympics, and, on the opening men’s race, the effort paid off (13 RF camera signals has only 10 when singal quality was on issues). To get RF signals everywhere IBC used two planes:three 50-Mbps signals were sent from each plane (each signal with four camera feeds). The RF system was also able to send tally information and camera controls to camera operators.
International Broadcast Centre
The International Broadcast Centre (IBC) is a temporary hub for broadcasters during major sport events. An International Broadcast Centre is created at every Olympic Games. Broadcasters from around the world build studios in what is generally a large conference centre.lympic Broadcasting Services provides each of these rights-holders a video and audio feed from each venue, beauty shots from around the Olympic venues, transmission facilities, etc.
