Adaptive high-resolution image transmission method using MPEG-DASH

With the emergence of new types of real-time network cameras, the demand for video streaming services is rapidly growing. To cope with this growing demand, the Moving Picture Experts Group (MPEG) has established a standard under the name Dynamic Adaptive Streaming over HTTP (DASH). MPEG-DASH adjusts the resolution to provide seamless audio and video streaming. However, in disaster situations, it is difficult to understand the accident situation using low-resolution videos. RNC-DASH is proposed as an optimization technique that continuously provides images with a certain resolution or higher. In disaster area surveillance, RNC-DASH helps accurate situational awareness (SA) and rapid response by receiving highresolution images.
