지상파 방송은 현재 초실감 시대에 발맞추어 풍부한 사용자 경험을 제공하기 위한 기술세대 전환기를 맞이하고 있다. 대한민국은 세계 최초로 4K UHD 지상파 DTV 방송을 상용화하며 기술적 도약을 이루었지만, 다각도로 변화하고 있는 세계 시장을 선도하기 위해서는 보다 선제적인 전략과 적극적인 연구·개발이 필요하다. 이에, 본 고에서는 차세대 지상파 DTV 방송 서비스의 효과적인 확산 및 관련 시장에서의 경쟁력 확보 전략 수립을 위해 국내외 지상파 기술 동향, 그리고 현 시점에서 다각적으로 접근하고 있는 방송망-통신망의 연동 기술 및 통신망에서의 방송 서비스 표준화 동향에 대해 알아본다.
