Abstract

Due to the increasing availability and popularity of digital television (DTV), the numbers of TV channels and programs that can be selected by consumers are also increasing rapidly. Therefore, searching for interesting channels and program via remote controls or channel guide maps can be frustrating and slow. In this paper, in order to better satisfy consumers, we propose a dynamic channel surfing scheme that reduces the channel seek distance in DTV. The proposed scheme dynamically rearranges the channel sequences according to the channel currently being watched to reduce the channel seek distance. The results of a simulation experiment demonstrate that the proposed dynamic channel surfing scheme reduces the channel seek distance for DTV channel navigation when up-down channel selection interfaces are used.

디지털 방송이 본격화되고 디지털 텔레비젼의 보급이 일반화되면서 시청자가 선택할 수 있는 채널의 수와 프로그램의 수는 기존 텔레비젼 환경과 비교하여 시청자가 이용할 수 있는 프로그램 리소스들이 큰 폭으로 증가되고 있다. 이러한 변화로 수백 개의 채널에서 시청자가자신이 선호하는 프로그램 채널을 찾기 위해서 리모컨이나 방송 편성표를 통해 검색하는 것은 많은 시간과 노력이 필요하다. 따라서, 본 논문에서는 up-down 채널 리모컨를 이용해 선호하는 프로그램 채널을 선택하는 시청자들을 위해, 현재 시청하는 채널을 기준으로 선호 프로그램 채널을 동적으로 배치함으로써 채널의 탐색 거리를 줄이는 방법을 제안한다. 그리고, 실험을 통해 그 성능을 평가한다.
