Six major Japanese broadcasters, including Tokyo Broadcast System, TV Asahi, ABC Asahi, TV Tokyo and TV Record in Brazil utilized the Smart-telecaster Zao H.265/HEVC encoder for live transmissions as part of their on-site operations during the Rio 2016 Olympic Games. Foccus Digital coordinated the rental packages with data services and delivered to broadcasters beginning in late July for site investigation and pre-Olympics coverage. The Smart-telecaster Zao provided international broadcasters with robust transmission over 3G/4G mobile networks with exceptional transmission stability. The advantage of compression efficiency and lower bandwidth requirements of HEVC contributed major benefits through monetary savings and expanded access. Capitalizing on the Smart-telecaster Zao’s lightweight design and extended battery life, broadcasters were able to get to and transmit from the essential Olympic events quicker and with significantly improved image quality.
The primary transmission sites included Maracanã and Engenhão Stadiums, Barra Olympic Park, Marina da Gloria and Copacabana Beach. The Smart-telecaster Zao transmitted flawlessly in full HD in all venues averaging 5.5 Mbps utilizing (2) VIVO and (4) Claro 4G SIM Cards. Soliton’s proprietary RASCOW transmission control technology ensured smooth, low-latency video/audio transmission, even in localities with extremely limited bandwidth. The 4G infrastructure in Rio de Janeiro performed considerably well and was built upon the structure laid out as a requirement for the 2014 FIFA World Cup. Transmission of content over IP to servers in Japan provided broadcasters with a very cost effective operation and the ability to economize data usage.
