26,000 Worshippers, Two Venues, One Prayer: Yoido Full Gospel Church Links CGI’s 50th Anniversary Rally Live with TVU G-Link
Yoido Full Gospel Church connects two Seoul venues in real time over the internet, keeping worship, hymns and prayer in step, while GoodTV deploys G-Link for contribution and distribution

The rally, part of CGI’s World Church Growth Conference, drew around 6,000 people to Jamsil Students’ Gymnasium. More than 10 km (6 miles) away, about 20,000 more joined from the main sanctuary of Yoido Full Gospel Church, following the worship, hymns and prayer as they happened. Among those taking part were roughly 3,000 pastors from 60 countries.
“When thousands of people are praying together across two venues, the remote congregation has to feel like they’re in the room,” said Johnny Ha, Sales Director, Korea, at TVU Networks. “Any visible delay or dropout breaks that. G-Link let the church keep both venues in step over everyday internet connections.”
GoodTV, another TVU customer, deployed the largest G-Link solution in Korea, connecting Yoido Full Gospel Church with its on-air transmission center for both contribution and distribution, extending the service to viewers on GoodTV and FGTV well beyond the two halls.
G-Link is an IP-based, point-to-point system that sends live video in both directions over the public internet or a private network. It accepts TVU, SDI and IP sources and outputs SDI or IP, so it plugs straight into existing production systems, social platforms and CDNs. TVU’s ISX transmission protocol, link aggregation and HEVC variable-bitrate encoding adapt to changing bandwidth, delivering sub-second latency when network conditions allow. The range scales from HD to 4K and 8K, with G-Link 4K supporting 4K60p HDR and 10-bit 4:2:2 encoding.
Because it runs over the internet rather than dedicated fiber, satellite or microwave links, organizers no longer need a separate line for every venue. That shortens setup and keeps costs down for any event spread across multiple locations, from religious gatherings and festivals to sporting events and product launches.
For the 26,000 people at CGI’s anniversary rally, the result was one service, not a main event and an overflow hall. More than 10 km from the stage, the congregation in Yoido sang and prayed in step with Jamsil, as one gathering marking 50 years of CGI.
