Under a 5G (5th generation mobile communication system) network environment, SOFTBANK will utilize the infrastructure for video transmission using MEC (Multi-access Edge Computing) and artificial intelligence (AI) to improve the resolution and image quality of video. We conducted a demonstration experiment of “super-resolution” to enhance. NVIDIA’s “NVIDIA Maxine” was used as the platform for video transmission. In the demonstration experiment, it was confirmed that low resolution (equivalent to 180p) video can be transmitted in Softbank’s 5G network environment, and “super resolution” processing by AI can be performed on the MEC server to generate high resolution (equivalent to 720p) video. did.

We also confirmed that by incorporating a voice noise removal function into the MEC server, users can use web conferencing with clear voice without using special equipment such as expensive microphones. This proved the effectiveness of AI and MEC for uplink communication in a 5G environment. With the rapid spread of telework, there are increasing opportunities to use services that upload videos in real time, such as web conferencing, and the problem is that the uplink capacity is tight. To address these issues, SoftBank is using NVIDIA Maxine to develop a system that enables high-quality video distribution while curbing data traffic on mobile networks.
