International sporting events have often been the testing ground for significant new television technology and this year's Commonwealth Games was no exception. In a successful trial by BBC R&D, live pictures from multiple "4K" cameras, were relayed, vision mixed and broadcast entirely via broadband.
International sporting events have often been the testing ground for significant new television technology and the 2014 Commonwealth Games was a very good example of this. In a successful trial by BBC R&D, live pictures from multiple "4K" cameras were relayed, vision mixed and broadcast via broadband and DTT
In this evening's event John Zubrzycki, Principal Research Engineer, will introduce two presentations by colleagues from:BBC Research & Development
Presentation 1: Live multi-camera UHD production using IP technologies
Peter Brightwell, Lead Research Engineer, Automated Production and Media Management Section, will report on a research trial of live Ultra High Definition (UHD) production at the Commonwealth Games using up to four '4K' cameras and a software-based live production gallery. The application of broadband network technologies based on the Internet Protocol (IP) to programme production offers a range of potential advantages such as reduced costs, due to the economies of scale of using systems developed for computer data transportation, to only needing one network for all types of video, audio and data traffic used to make a TV programme. However, one of the major challenges is to be able to make live multi-camera TV programmes using IP. The practical experiences gained will be used to further the development of IP production and feed into standardisation.
Presentation 2: Live broadcasting trials of UHD over DTT and via Broadband
Phil Layton, Section Lead, Broadcast and Connected Systems Section, will report on two trial broadcasts of UHD; one of selected World Cup matches and the other of the Commonwealth Games events from the IP production trial. These trials provided useful information on the technical feasibility of broadcasting UHD by DTT or Broadband using the new High Efficiency Video Coding (HEVC) standard; particularly considering how Broadband might develop to become a practical broadcasting medium. There were further challenges from the World Cup trial of receiving the UHD contribution feed from Brazil and working with IP-based production at the Commonwealth Games trial.
Following the presentations John Zubrzycki will chair a Q & A session.
