Abstract

Along with the development of network transmission technology, the IPTV market is growing in fast pace. Additionally the UHD resolution broadcasting system along with user experience (UX) that provides better service to user has attracted attention recently since there are not enough research has been done with differentiated the UX that can enhance the UX yet. Therefore we proposed a low complexity syntax level image stitching implementation technique that run with multi-view services, which makes possibility to view multiple channel or video contents on the screen at the same time. Simulation results have demonstrated the liability and effectiveness of the proposed algorithm by showing that capability of generating more than 80 frames per second by stitching four Full-HD size videos into UHD frame.

네트워크 전송 기술의 발달에 따라 IPTV 시장이 급격히 성장하고 있다. 또한 더 좋은 서비스를 사용자에게 제공하는 UHD급 방송 및 UX가 주목 받고 있다. 반면에 기존 UX와 차별화 된 사용자 경험을 극대화 할 수 있는 기술에 대한 연구는 많이 진행되지 않고 있다. 따라서 본 논문에서는 사용자가 한 화면에서 여러 채널 및 비디오 콘텐츠를 동시에 시청할 수 있는 멀티뷰 서비스와 이를 수행하는 저복잡도 구문 수준 영상합성 기술을 제안한다. 실험 결과, 제안 알고리즘은 Full-HD 해상도를 가진 4개 영상, UHD급 영상을 1초에 80장 이상 합성할 수 있어, 실시간 적용이 가능함을 보여준다.
