BROADCAST FOCUS


“Tis is not done in the basic simulcast mix. We are doing the surround mix at the IBC because we think that within such a big production like this the sound guy in the venue cannot be expected to successfully do the stereo mix and all the packages AND a surround mix at the same time.”


Additional audio content will also be made available via the ISO feeds. Tis includes outside ambience, aerial ambience, and a microphone on the CableCam.


To further ensure consistency of coverage across the entire tournament, each venue will have an identical audio set-up [see box out, right] with the same mics and desks.


Dan Miodownik, director of production services at HBS, says: “We’ve been quite specific about what we want to achieve [this year], with single microphone choices through Sennheiser and Schoeps. We have 12 audio desks, all Lawo, however they will be configured and set up in the way in which each audio engineer wants to work.”


To help cope with the huge number


of commentary positions a fully IP-based commentary system is being used for the first time. Developed by Lawo and HBS the LCU (Lawo Commentary Unit) will connect all the venues and the IBC in Rio via a multitude of 10 Gbps paths. “We always try to do new things and audio via IP is one of the big technology breakthroughs in the last year,” says Gobbel. “At the IBC we will have the first ever IP-based distribution [Ravenna/AES47] of audio feeds to rights holders at an event of this scale.”


Of the 840 commentary units that will be used, 240 will be IP-based LCUs.


At the same time a single comms system for the venues, provided by Riedel, will allow the crew to talk to each other “at whatever time they need to do so for the entire period of the event”.


“50 percent of the enjoyment of a football match comes from the audio,” concludes Gobbel. “Tat is why we are putting a lot of effort into all the little bits and pieces.”  www.hbs.tv
