The Nippon Telegraph and Telephone Corporation (NTT) has developed technology to convert 4K120Hz and FHD240Hz HDMI signals into long-distance transmission signals with what it says is the world’s lowest delay of 0.1 milliseconds or less.
Combining the technology with the IOWN All-Photonics Network (APN), means that up to 4K video displaying 120 frames per second can be transmitted in real-time between remote locations, said the company.
The solution puts HDMI signals, including audio, directly into large-capacity, fixed-bandwidth, fixed-delay layer 1 signals, eliminating the time required to compress and decompress video signals.
This makes it possible to transmit video to remote locations without video quality degradation or delay fluctuations due to communication, said NTT.
As a result, when the fibre propagation delay time is negligibly small, the delay time from video input at the transmission side to video output at the receiving side is kept to 0.1 milliseconds or less.
In addition, by transmitting 4K120Hz and FHD240Hz high-resolution and high refresh rate video signals without compression, ultra-fast-moving video can be transmitted to distant locations with high resolution and no degradation in motion, added the company.
According to NTT, the technology can be used for VR and AR applications as well as “remote activities.”
