abstract = "The Internet including mobile networks is developing to overcoming the limitation of physical distance and providing or acquiring
information from remote locations. However, the systems that use video as primary information require higher bandwidth for recognizing
the situation in remote places more accurately through high-quality video as well as lower latency for faster interaction between devices
and users. The emergence of the 5th generation mobile network provides features such as high bandwidth and precise location recognition
that were not experienced in previous-generation technologies. In addition, the Mobile Edge Computing that minimizes network latency
in the mobile network requires a change in the traditional system architecture that was composed of the existing smart device and high
availability server system. However, even with 5G and MEC, since there is a limit to overcome the mobile network state fluctuations only
by enhancing the network infrastructure, this study proposes a high-definition video streaming system in ultra-low latency based on the
SRT protocol that provides Forward Error Correction and Fast Retransmission. The proposed system shows how to deploy software components
that are developed in consideration of the nature of 5G and MEC to achieve sub-1 second latency for 4K real-time video streaming. In
the last of this paper, we analyze the most significant factor in the entire video transmission process to achieve the lowest possible latency."
