Drastically Improved Audio Reliability

RIOT Broadcast uses a different technology stack to conventional hearing augmentation and Wi-Fi based stadium audio solutions. Our solution:

Adapts to network conditions

Aims to preserve the human voice

Provides multiple levels of error correction

Originally developed by Google, our technology stack branches and specialises work done by the open source community. We assigned some of the world’s best audio developers to optimise a forthcoming Metaverse technology to achieve the audio latency, scalability and stability we have today on both Android and iOS. Our eco-system is highly supported and more audio-performant than any other mobile-radio streaming service. It is perfect for the stadium.

80-150ms Latency. Why?

The stadium is a unique beast with unique challenges in acoustic physics & technology. Faster is often less ideal. In optimising our audio performance, we have considered the performance of stadiums worldwide including:

Typical reverb time, impulse response, speaker positions and distances

Latency of IPTV and audio-hardware

5G & Wi-Fi network conditions in-stadium vs optimised buffering

Human thresholds of vision, audio impulse perception and the speed of sound

The impulse response below shows how one short sound is perceived. It shows the initial time gap, heavy early reflections and long reverberation tail. Stadiums worldwide typically have an intelligibility loss of 50% or more, meaning over 50% of the words spoken over the PA system are not humanly comprehensible at a typical listener seat.

By positioning our latency near the front of the impulse response we provide the best opportunity to enhance PA audio, sync with IPTV and provide perceptibly instant commentary and real-time fan engagement.

A New Dimension for Sport, Fans & Business. Really.

Biased (team based) radio commentary

Lead a fan chant to 100,000 people. Consider that chant affecting player behaviour & the match Social Facilitation Theory

Realtime unbiased commentary in-stadium

Referee microphone audio. This is a surprisingly popular choice by listeners in-stadium

Provide these streams at-home with the ability to synchronise them to TV

In-app-purchase can monetise premium stream access

Many of these real-time streams are already being achieved/monetised by our existing broadcast partners

Security & Platform Reliability

99.99% global uptime

Multi-cloud redundancy

Multi-region infrastructure

JWT access tokens & permissions

256-bit TLS transport layer encryption

Secure websockets

AES-128 media layer encryption

Secure API design

TV Synchronisation

Bring biased commentary (and other streams) into the lounge room with our TV synchronisation feature.

All TV broadcasts are delayed. The exact delay varies depending TV station, match location and other factors. TV delay typically ranges from 4-90 seconds.

RIOT provides a settable delay to match all TV broadcasts.

Set the delay, and turn the sound down on your TV.
