Abstract

The introduction of virtualization technology in the broadcasting field is actively progressing broadcasting service automation and intelligence based on the effective operation of IT resources throughout the broadcasting industry ecosystem. In recent years, there is increasing interest in increasing the flexibility of various broadcasting resources and increasing the efficiency of interworking with other networks through network virtualization of the broadcasting network infrastructure. The fundamental transformation from the broadcasting network to the IP paradigm is facing a situation where it is necessary to solve various problems for the effective interworking of Internet-based service platforms and 5G networks and the development of new convergence services. In other words, for organic and effective interworking with the next-generation broadcasting network represented by ATSC 3.0, a mobile communication network represented by 5G, and the Internet, a number of difficulties must be solved. In this paper, the basic technology and status for the convergence of ATSC 3.0 broadcasting network and mobile communication network represented by 5G was examined, and a plan for the ATSC 3.0 broadcasting network and 5G network to interwork with each other as a network was described.

방송 분야에서의 가상화 기술도입은 방송산업 생태계 전반에 걸쳐 IT 자원의 효과적인 운영을 기반으로 방송 서비스 자동화 및 지능화가 활발하게 진행되고 있다. 최근에는 방송망 인프라의 네트워크 가상화를 통해 다양한 방송 자원의 유연성을 높이고 다른 망과의 연동 효율성을 높이고자 하는 관심이 높아지고 있다. 방송망에서 IP 패러다임으로의 근본적인 변환은 인터넷 기반 서비스 플랫폼들과 5G 망과의 효과적인 연동과 신규 융합 서비스 개발을 위한 여러 가지 문제를 해결해야 하는 상황에 직면하고 있다. 즉, 이처럼 ATSC 3.0으로 대표되는 차세대 방송망과 5G 대표되는 이동통신망, 인터넷과의 유기적, 효과적인 연동을 위해서는 수많은 난제를 해결해야 하는 상황이다. 본 논문에서는 ATSC 3.0 방송망과 5G로 대표되는 이동통신망과의 융합을 위한 기본 기술 및 현황을 살펴보고, ATSC 3.0 방송망과 5G 망이 서로 망대 망으로 연동하려는 방안에 관해서 기술하였다.
