During the Commonwealth Games BBC Research and Development took the opportunity to unveil a range of new trials and public demonstrations as part of its Games showcase. These experiments brought together a wide range of industry partners and are helping to shape BBC R&D’s vision for the future of TV, and included a number of broadcasting milestones:

• The first ever Ultra-HD broadcast of a Commonwealth Games

• The first major live event to be produced and delivered entirely over the internet

• The first UK trial broadcasting live coverage over 4G mobile networks

• The first live virtual reality broadcast combining 360 degree video with 3D audio

The first public outing for several cutting-edge BBC R&D projects demonstrating the editorial and creative potential of a new internet-based broadcasting system.

Matthew Postgate, Controller of BBC R&D commented, “The future isn’t being created by one company or different companies working in isolation, this is a future that is going to be created by collaboration, and the BBC is committed to open innovation and open research.” The Showcase centred on two broadcasting firsts with BBC R&D’s plans to broadcast certain elements of the Commonwealth Games in Ultra-HD and an initial version of a new internet-based broadcasting system.

The Commonwealth Games gave the perfect platform for BBC R&D to announce the first public demonstrations of projects taking advantage of this new system - demonstrating its potential for richer, more interactive and more personal ways of telling stories to audiences – as well as the first live 4G mobile broadcast in the UK. These include...

Ultra-HD

Visitors to the Showcase saw a special BBC R&D production of the Commonwealth Games in Ultra-HD, explored some of the technical challenges facing Ultra-HD production, such as using higher frame rates and higher dynamic range, and saw how it’s put together in the BBC’s experimental IP Production Gallery. Visitors also experienced what the future of TV viewing in the home may be like, with a joint demonstration from BBC R&D and Cisco. The demo explored how Ultra-HD footage from the Games could be experienced with adaptable displays and contextual applications that provide a truly immersive and enhanced viewing experience.

Venue Explorer

Gives users the freedom to explore multiple live events taking place in one venue at the same time. It also demonstrates how all audiences could benefit from an Ultra-HD production using standard definition devices. For the Showcase, a fixed wide-angle Ultra-HD camera provided a live feed of all the track and field action taking place in Hampden Park. This allowed users to use a standard tablet to pan around and zoom into the events they’re interested in. The audio will automatically adjust to match the view and, as it’s powered by an Ultra-HD feed, the resolution never drops below standard HD. Interactive graphics overlaid on the video provides additional information relevant to the scene.

4G mobile broadcasting

In a UK fi rst BBC R&D collaborated with EE, Huawei and Qualcomm on a trial to broadcast live footage from the Games over the EE 4G mobile network. Handheld devices are an increasingly popular way of consuming BBC programmes but conventional streaming over mobile networks can buffer or freeze at times of heavy congestion, as content needs to be sent individually to every user. 4G broadcasting offers an alternative to this, allowing live streams to be transmitted once over the mobile network to a large number of users simultaneously. Not only does this offer potential audience benefi ts due to the increased quality and reliability, it can also be a more effi cient way to deliver popular shows and live events to audiences.

Virtual reality

By combining existing research into 360 degree video and 3D audio, BBC R&D, with the assistance of UCL, created the most immersive live virtual reality broadcast to date. In this demonstration, a panoramic, 360 degree video camera, and a 3D audio microphone were placed into the SSE Hydro Stadium in Glasgow, streaming the live feeds to an Oculus Rift virtual reality headset in the Glasgow Science Centre. This provided the viewer with the sensation of being transported inside the stadium and being part of the crowd. This work forms part of ongoing projects to explore the creative and editorial potential of new consumer audio-visual technology.

Augmented video

An experimental extension to BBC iPlayer that can draw graphical overlays on top of video streams. As with subtitles, these graphics can be activated or deactivated by the viewer. In sport these could include putting names above player’s heads, adding text to show how fast a person is running or highlighting a ball to assist viewers with poor eyesight. Other examples could include adding zoological information about a species being shown in a nature documentary, or showing recipes during a cookery programme. At the Showcase, visitors were able to see the prototype in action, where the graphics were used to provide insights into gymnastics events.

The Biggest Toy Shop in the World
Emma Morrison When Nigel Woodford started his career at BBC Wood Norton in 1962, television was black and white and BBC Two had not yet been launched. In 2018 Nigel will retire, and Richmond Film Services, the pro-audio equipment rental company set up by Nigel in 1973, can count numerous contributions to iconic moments in British cultural, sporting and film history over this time.

How todays technology platforms can make AMAZING seem mundane
Bruce Devlin - new Some things never change. It's September and it's time for another IBC. Maybe I'm getting old and maybe I have selective memory about the past, but recently there hasn't been the buzz of years gone by. Sure, as you wander around the vast halls there will be lots of enthusiastic sales people trying to give you the best demo possible, but something has changed and to survive, I believe that vendors and customers need to change too.
