SK Telecom completes live TV broadcast over its 5G network

As a follow on to yesterday’s IEEE techblog on Korea 5G and ideal content, SK Telecom has completed the first live TV broadcast over its commercial 5G network and live broadcasting solution.

The operator ushered in 2019 with a live broadcast of Korea’s largest New Year’s event at the Bosingak pavilion in Seoul from around 11 minutes starting at midnight Korea Standard Time.

The live broadcast used SK Telecom’s T Live Caster live broadcasting solution, which the network operator has developed over a four year period.  T Live Caster is designed to enable live broadcasting of video taken by smartphones over channels including TV and personal broadcasting over 5G anThe  video taken by smartphone cameras installed with the T Live Caster app and connected to connected to a 5G mobile router was transmitted through 5G stations and entertainment channel XtvN’s transmission system for cable and IPTV viewers of the channel.   

The video was taken by smartphone cameras installed with the T Live Caster app and connected to 5G mobile routers and transmitted through 5G base stations and XtvN’s transmission system to cable and IPTV viewers of XtvN.

Despite the highly congested data environment, the video was transmitted at a latency of less than one second, comparable to that of existing wired broadcasting systems.

“With today’s successful live TV broadcasting over commercial 5G network, SK Telecom ushers in a new era of 5G-based media services,” SK Telecom SVP and head of 5GX IoT/Data Group Choi Nak-hoon said.

“In this new era, individual creators will be able to provide high-quality live broadcast anytime, anywhere, via 5G smartphones.”

South Korea has successfully switched on commercial 5G network on the first day of December, officially marking the era of high-speed network. The country’s No.1 mobile carrier has become the first to make a commercial 5G video call, using a prototype Samsung smartphone.

SK Telecom’s 5G network currently covers main areas of 13 cities and counties nationwide, including Seoul, four cities in Gyeonggi-do (Seongnam, An-san, Hwaseong, Siheung), six metropolitan cities, Seogwipo in Jeju Island, and Ullengdo and Dokdo Islands in Ulleng county.


SK said it plans to continue to enhance the quality of T Live Caster to UHD and interconnect the solution to personal broadcasting platforms within the year.

Plans also call for tapping into the drone broadcasting market. Last June, SK Telecom struck a partnership with drone manufacturer DJI to jointly develop a drone video surveillance solution.

  1. Percepto uses SK Telecom’s 5G network to fly autonomous drones

    Autonomous drones have successfully been flown by Percepto over SK Telecom’s 5G trial network.

    SK Telecom is the largest mobile operator in Korea and commercialised its 5G network in December 2018.

    Dain SNT, Percepto’s representative in Korea, has been collaborating with SK Telecom to apply Percepto’s solutions to SK Telecom’s commercial 5G network.

    Percepto is a drone-in-a-box (DIB) solution that provides a range of communications schemes to its global customers. It also offers autonomous flights over cellular networks. This milestone prepares Percepto to provide its customers with significant operational advantages including better real-time video stream quality; reduced battery consumption, which means longer mission times; and greater distances and readiness for greater data processing in real time.

    Earlier this year Percepto was recognised by Frost & Sullivan for its onboard computing processing capabilities, allowing Percepto to conduct real-time analytics. Supported by 5G networks, Percepto users are more likely to gain faster and more accurate aerial insights.

    “We are proud to have been selected by SK Telecom to demonstrate the potential of both 5G and autonomous drones,” said Percepto Chief Executive Officer Dor Abuahsira.
