SK Telecom launches live-streaming tech

​SK Telecom has commercialised the industry's fastest mobile live-streaming technology, dramatically reducing latency from 15 seconds to just three.

SK Telecom on Tuesday launched a new live-streaming service called T Live Streaming, and said it will be applying the technology first to live sporting events on local streaming channel SPOTV on SK Broadband's mobile media platform Oksusu.

The telco added that the technology will be applied to other Oksusu channels to allow more users to experience live-streaming services with super-short latency rates.

The technology can also be applied to platforms like Multi-Channel Networks (MCNs) that rely on viewer feedback from viewers, so reduced latency in live broadcasts helps to increase viewer-broadcaster interactions.

"SK Telecom continues to enhance users' mobile live video streaming experience through T Live Streaming, an enabler of true real-time mobile streaming services," said Park Jin-hyo, senior VP and head of SK Telecom's Network R&D Center. "While promoting the international standardisation of the technology, SK Telecom will also provide T Live Streaming SDK to allow developers to create diverse media solutions."

SK developed T Live Streaming by customising MPEG Media Transport (MMT), a standard developed by the Moving Picture Expert Group (MPEG), to the mobile network environment.

MPEG is a working group of ISO/IEC, in charge of developing international standards for the coded representation of moving pictures and audio and the combination of both, including compression, decompression, and processing.

Since February 2015, SK Telecom has served as the chair of the MMT sub-working group, and is working with deputy chairs, among them Samsung Electronics, to promote the standardisation of T Live Streaming technology.

SK Telecom said its new technology is much better than the existing live streaming technologies MPEG-2 Transport Streaming and Http Live Streaming, which have been used as media transmission technologies for the past two decades.

MPEG Media Transport will play a critical role as the next-generation mobile protocol when it is fully adopted as the standard by the end of next year and replaces the two current standards.
