ROUTE/DASH server system development for realtime UHD broadcasting

摘要

Recently, digital broadcasting has been increasingly demanded for high-definition broadcasting services such as HDR UHDTV. In addition, consumption environment of multimedia is also changing to a tendency to enjoy through various types of terminals. In order to satisfy such changes, we developed a ROUTE/DASH Server system to be inputted real-time encoded UHD stream, packetize it into ROUTE/DASH and output it to UDP, and we also verify it through developed ROUTE/DASH client. The developed ROUTE/DASH Server system provides a way to solve that the limitations of various network and receiving environment of existing MPEG-2 TS system. Using the developed system, it is expected that it can be used not only for multimedia service through broadband but also for transmission system of broadcasting system of ATSC 3.0 in which next standard broadcasting is being standardized.
