Currently being played out in South Korea, the U-20 World Cup has seen Host Broadcasters KBS, MBC and SBS include Tieline codecs in the services provided to local and foreign rights holders.

Tieline has supplied 32 i-Mix G3 codecs to South Korean systems integrator Coil and Wire (CNW) as part of the event’s commentary equipment. ‘CNW secured the contract with the Host Broadcasters to supply all equipment and fit out all commentary positions for the event,’ says VP Sales APAC & EMEA, Charlie Gawley. ‘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 is being used to broadcast all 52 games played throughout the tournament.’

CNW has installed five i-Mix G3 audio codecs in commentary positions at venues at Cheonan, Daejeon, Incheon, Jeju and Jeonju, plus seven i-Mix codecs in commentary positions at the main stadium in Suwon.

‘Commentary audio is being transported directly from the venues to Tieline Commander G3 rackmount codecs at each South Korean rights holder’s studio for local transmissions,’ Sheen says. ‘South Korean rights holders KBS, MBC and SBS are using IP over the public internet for their primary connections, with POTS lines as backup. Other European, Asian and American rights holders are predominantly using ISDN lines with POTS 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,’ he adds. ‘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.’

The i-Mix has five balanced XLR inputs and local announcer commentary audio at each venue is mixed with splits of international sound and PA audio. Codecs also receive communications audio routed through commentary control.
