KT announced that it has joined hands with Nokia to successfully develop and demonstrate a new “ultra-low-delay eMBMS” technology, which can send HD video clips to multiple users at once with a time delay of less than one second.
The ultra-low-delay eMBMS technology is an innovative technology that dramatically shortens the delay time compared to existing LTE eMBMS, and simultaneously sends a multi-channel service to offer HD video clips and diverse information to multiple users who gather in certain areas such as large-scale auditoriums and sports stadiums, with a time delay of less than one second.
The technology is meaningful to the two companies particularly since it is the first fruit that has been successfully developed and demonstrated after their two CEOs signed a memorandum of understanding (MOU) to co-develop a next-generation 5G network structure in a bid to bring the commercialization of 5G closer when KT Chairman Hwang Chang-kyu visited the Nokia headquarters in May.
The technology demonstration was conducted by checking the time needed to send the HD video clips and playing them via smartphones at the Nokia Research Center in Munich, Germany. The test was considered to be a success when the technology took less than one second from the video input to play back with smartphones.
In addition, the ultra-low-delay eMBMS technology uses “mobile edge computing,” which gives users uninterrupted service by reducing the delay time between requesting the service and receiving the data by having a local cloud server built in to the closest base station. It has established a foundation to provide a service to send HD content more quickly in the 5G era of the future.
