The brief
An international summit organizer brought a two-day program to Hangzhou with delegations and remote audiences across Asia, Europe and North America. The requirement was unusually wide: six interpretation languages — English, Chinese, Japanese and three others — each delivered as its own clean stream, and simultaneous distribution to 11 platforms. The international audience watched on YouTube, Zoom and LinkedIn Live; the domestic audience watched on WeChat Channels, Bilibili, Douyin and Weibo. All of it had to originate from a single venue in China, with no platform treated as an afterthought.
What we did
We designed the production around one control position feeding many outputs. Six broadcast cameras covered the main stage — wide, tight, audience, jib and two speaker cameras — switched by a dedicated technical director with lower thirds, agenda cards and sponsor graphics prepared in the organizer's brand before show day.
The audio chain was the core of the job. We took discrete feeds from each interpretation booth and built six parallel program mixes, one per language, each married to the same switched picture. Three stream engineers managed encoding and distribution: redundant encoders per language group, a bonded 4G/5G backup path alongside the venue line, and a stream test to every one of the 11 destinations during rehearsal — not on the morning of the event.
The organizer's team briefed us in English throughout; our bilingual technical producer ran the room in Chinese and acted as their single point of contact from the site survey to the final archive delivery.
The result
Both show days ran without a dropped stream on any platform or in any language.Peak concurrent viewers across the 11 platforms substantially exceeded the venue's physical capacity, which was the point: one event in Hangzhou, watched live in six languages on both sides of the network. The organizer received full program and ISO recordings plus a per-language archive package for on-demand distribution, and this project remains the reference we point to when a client asks whether simultaneous China-plus-overseas streaming at scale actually works. It does.
