Tieline, CNW Deliver Gear for U-20 World Cup

Host Broadcasters are using the i-Mix G3 codecs for live commentary

Through South Korean systems integrator Coil and Wire, Tieline has supplied 32 i-Mix G3 codecs for coverage of the U-20 World Cup, which began on May 20 and concludes June 11.

South Korean Host Broadcasters KBS, MBC and SBS, on behalf of local and foreign rights holders, are using the codecs for live commentary during all 52 games.

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

“Commentary audio is being transported directly from the venues to Tieline Commander G3 rack mount codecs at each South Korean rights holder’s studio for local transmissions,” said Hyung-uk Sheen of CNW. “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 has five balanced XLR inputs and local announcer commentary audio at each venue is mixed with splits of international sound and PA audio. The codecs also receive communications audio routed through commentary control.

“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,” said Sheen. “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.”
