Tieline’s i-Mix G3 codecs were used by systems integrator Coil and Wire (CNW) to deliver commentary for South Korean host broadcasters KBS, MBC and SBS during the recent Fifa U-20 World Cup that took place in the country. i-Mix G3 is an IP codec for broadcast applications, which serves as a multi-faceted unit that can be used as a mixer and a commentary control unit.
‘CNW secured the contract with the host broadcasters to supply all equipment and fit out all commentary positions for the event,’ recalled Charlie Gawley, VP sales APAC and EMEA at Tieline. ‘The i-Mix was specified by Hyung-uk Sheen from CNW as the codec of choice because of its flexibility and ability to connect over IP, ISDN and POTS. The codec was used to broadcast all 52 games played throughout the tournament.’
The stadia in Cheonan, Daejeon, Incheon, Jeju and Jeonju were each equipped with five i-Mix G3 audio codecs to cover their commentary positions. A further seven were installed at the main stadium in Suwon.
‘Commentary audio was transported directly from the venues to Tieline Commander G3 rack mount codecs at KBS, MBC and SBS’ studios for local transmissions,’ said Mr Sheen. ‘They used IP over the public internet for their primary connections, with POTS lines as backup.
‘The i-Mix can connect reliably over IP, ISDN and POTS, and failover seamlessly to any transport if required, which was a very important factor,’ Mr Sheen continued. ‘The solid track record of the codec at other major events, like the Asian Games in 2014, simplified the decision to use the i-Mix for this event.’
