Large-Audience Live Streaming: Mediactive’s Offering for International Events

•

October

2026

For the communication departments of large public and private organizations running conventions and events for a large, international audience, the question of broadcast infrastructure is a defining one.

Past a certain audience threshold, with several thousand participants connected at once across multiple continents, standard video conferencing and streaming solutions hit their limits. Bandwidth saturates, picture quality drops, and latency creeps in. For high-stakes events like these, the reliability of the live broadcast setup becomes the number one factor in whether the event succeeds.

To meet these demands, Mediactive is launching a
new large-audience live streaming offering, powered by the Vodalys platform..

It’s built for event and communication teams running events with audiences of several thousand simultaneous participants, often multilingual, at a national or international scale, and in some cases requiring broadcast into mainland China, which comes with its own specific regulatory requirements.

The Technology Offering: Broadcast Infrastructure Built for Large Audiences

The Vodalys platform now includes a new large-audience video portal offering that brings together:

A multi-CDN broadcast infrastructure combining the Akamai CDN, one of the most extensive content delivery networks in the world, which ensures optimized delivery in an international context at quality levels suited to mission-critical events, with a specialized CDN for broadcasting into mainland China that complies with local regulatory requirements, including the ICP license.
The option to add an eCDN solution, provided by Mediactive’s technology partners, which optimizes signal distribution across internal networks through a secure peer-to-peer approach.
Redundancy across the entire broadcast chain, with real-time quality monitoring, guaranteeing service continuity and the ability to step in immediately.
A selection of Vodalys video portal features tailored to large audiences: interactive tools calibrated for connection peaks, and AI-powered translation and transcription for multilingual events.

The Building Blocks of the Technology Offering: eCDN and an Optimized Video Portal

eCDN technology

For organizations broadcasting internally, over their own corporate network, concentrating tens of thousands of simultaneous video streams creates a real risk of saturation.

The eCDN, or Enterprise Content Delivery Network, solves this with a secure peer-to-peer approach: the video stream is optimized and shared locally between participants’ computers, reducing the load on central bandwidth while guaranteeing optimal picture quality for every viewer.

Optimized video portal

Beyond infrastructure, the participant experience is at the heart of the offering. The Vodalys large-audience video portal is designed to absorb simultaneous connection peaks: fast access through SSO or any other access control system, plus interactive tools and real-time audience monitoring from the admin interface.

Thales and other major industrial groups rely on this setup for multilingual broadcasts involving several thousand participants connected from different countries.

The Professional Services Offering: Before, During, and After the Live

Mediactive’s professional services offering structures its support in three phases, before, during, and after the live broadcast, to guarantee the reliability of every large-audience stream.

Beforehand: network audits and load testing
Before every event, Mediactive’s engineering teams put the company’s network to the test by simulating thousands of simultaneous connections directly on the client’s infrastructure. These dry runs and silent tests make it possible to validate how the broadcast architecture behaves, spot potential bottlenecks, and fine-tune the whole setup well before event day.
During the live: real-time monitoring and support
Throughout the live broadcast, a dedicated Mediactive team monitors the event alongside the client’s teams. From the Vodalys monitoring interface, they continuously track signal quality, the number of connected participants, and infrastructure stability by geographic region. If anything goes wrong, the team steps in immediately to fix the issue before it affects the participant experience. For an event involving tens of thousands of employees at once, that hands-on operational presence is what turns a robust infrastructure into a fully controlled broadcast, from start to finish.

After the event: audience analytics report
After every broadcast, Mediactive delivers a detailed analytics report that traces audience behavior throughout the event: number of connected viewers, connection peaks, broadcast quality, and breakdowns by language and geographic region. It’s valuable data for event and communication teams looking to measure the real reach of their event and fine-tune future setups.

A Proven Offering for a Major French Group’s Communications

With this new offering, Mediactive has already guaranteed the broadcast of several large-audience TotalEnergies events, covering group-wide communications and CEO addresses, streamed simultaneously to tens of thousands of employees around the world.
