Brazil delivers World Cup broadcasting tech

Government-owned telecommunications company Telebrás completed the tests for the World Cup broadcasting infrastructure successfully earlier this week.

Telebras is responsible for the tech supporting the video and audio high definition broadcasting of the World Cup matches. Its fiber optic network interconnects the 12 host venues to the International Broadcast Coordination Centre (IBC) in Rio de Janeiro, with redundant 30 Gbps links to ensure image quality.

Dense Wavelength Division Multiplexing (DWDM) technology is also being employed to allow simultaneous transmission of high-definition imagery, with equipment developed locally.

According to the company, the infrastructure is being incorporated into the Telebras metropolitan networks and is a World Cup legacy that will support the National Broadband Plan by offering high-speed broadband at lower prices.

Earlier this year, when the Brazilian government expressed concerns over the World Cup infrastructure delays, Communications minister Paulo Bernardo said that the broadcasting set-up would be ready in time for the tournament, but it would be completed "in a rush."
