Japan’s NTT Communications is working with Yamaha on technology that aims to realise highly realistic, low-latency, two-way live viewing.
The technology, which has been christened GPAP over MoQ, is currently aimed at the live music industry, but could easily be developed for live sport broadcasts.
GPAP has been developed by Yamaha, and can consolidate video, audio, and lighting and other stage-related data into a single data set and record/play it back. MoQ is a next-generation data transmission technology being researched by NTT Com that can distribute audio and video with low latency.
According to the two companies, distributing content via MoQ could reduce latency to a minimum of “about 0.1 seconds” compared to the current delay of about three seconds.
This could lead to viewers being able to experience the feeling of participating in a live performance without actually being there.
The optimal compression method can be applied depending on the type of GPAP data (audio, lighting data, etc.), which can compress the amount of data transferred by up to 90 per cent, said the two partners.
The technology uses a unique real-time data recovery control method according to the type of GPAP data, allowing for stable data transfer with low latency, with less risk of audio skipping or lighting control errors even in an unstable network environment.
