증강방송(Augmented Broadcasting)은 최근 스마트 기기의 보급으로 인해 대중적으로 알려진 증강현실(Augmented Reality) 서비스를 스마트 TV 와 같은 하이브리드 방송 환경에 접목하여, 시청자에게 기존에 느낄 수 없었던 TV 시청에 대한 몰입감과 콘텐츠 조작의 양방향성을 제공하고자 하는 새로운 방송통신 융합 서비스 개념이다. 증강방송에 대한 개념과 PC 기반의 테스트베드 시스템은 이미 다수 발표되었으며, 본 논문에서는 디지털 지상파 방송 환경에서의 증강방송 시스템 실현을 위해 DTV 기반의 증강방송 시그널링과 콘텐츠 동기화 방안을 적용한 재다중화기(Re-multiplexer)의 설계 및 구현에 관해 설명한다.
