  • 초고속 통신망의 발전으로 인터넷을 통한 고화질 비디오 서비스가 가능하게 되었으며 이에 따라 스마트TV, IPTV 서비스와 같은 방통융합서비스가 대중화 되고 있다. 그리고 이러한 추세에 맞추어 방송 이외의 매체를 통한 비디오 콘텐츠 소비가 증가하고 있고, IT사업자들과 가전사들이 방송 플랫폼 사업에 진출하는 등 전통적인 방송 산업 구조에도 변화가 일어나고 있다. 이와 같은 환경 변화에 대응하기 위해 KBS 기술연구소는 지상파 방송 기반의 하이브리드 TV 서비스를 연구하고 있고, 이를 OHTV(Open Hybrid TV)라는 이름으로 국내의 다른 방송사들 및 가전사 등과 함께 표준화하고 있다. 안정적이고 효율적으로 대용량 비디오를 전송할 수 있는 방송망과 양방향 특성을 가진 통신망을 같이 활용하는 하이브리드 TV 환경에서는 양방향 방송 서비스를 보다 효율적으로 제공하는 것이 가능할 것으로 기대된다. 이를 통해 TV 시청자에게는 개인화된 형태의 새로운 방송 서비스를 제공하고, 방송사에게는 전통적인 사업모델을 탈피하여 새로운 비즈니스 모델을 찾을 수 있는 기회를 줄 수 있다. 이미 유사한 개념의 서비스들이 국내외에서 다양하게 시도되고 있으며 본 논문에서는 OHTV 서비스 시나리오 및 요소기술과 이를 구현한 시스템을 소개한다.

  • It has been grown interests ot the convergence services about broadcasting and multicasting services such as Mobile IPTV. It needs the efficient scheduling and resource allocation algorithm because video contents have the large data. This paper proposes the resource allocation algorithm for the layered-encoded video coding in the multicasting services. Existing approaches only deal with the utility maximization in the current video frames. However, these algorithms have a problem for the Quality of Services(QoS) if the user's channel states are not good. We apply the delay constraint and find to maximize the utility values using the current content's frames and already assigned content's frames within the constraint periods. The performance of the proposed algorithm is evaluated by the higher layer transmission rates compared the existing algorithm and significantly improved for the QoS.
