Abstract: front page image
(EN)The present invention relates to a method of providing a mobile IPTV service, and a system for executing same. The method of providing a mobile IPTV service in a terminal that receives streams of a channel included in the same channel group includes the steps of: determining whether a channel currently providing a service and a selected channel belong to the same channel group; and, when the channel and the selected channel are determined to belong to the same channel group, streaming by the terminal decoding IPTV channel the selected channel from among channel streams which are being received. Accordingly, an average processing complexity can be minimized and fast channel change for a user to another channel within the same channel group can be guaranteed.
(FR)La présente invention porte sur un procédé de fourniture d'un service IPTV mobile et sur un système qui permet de l'exécuter. Le procédé de fourniture d'un service IPTV mobile, dans un terminal qui reçoit des flux d'un canal inclus dans le même groupe de canaux, comprend les étapes consistant : à déterminer si un canal fournissant actuellement un service et un canal sélectionné appartiennent ou non au même groupe de canaux ; quand il est déterminé que le canal et le canal sélectionné appartiennent au même groupe de canaux, à diffuser en continu, par le terminal décodant un canal IPTV, le canal sélectionné parmi des flux de canal qui sont en cours de réception. Par conséquent, une complexité moyenne de traitement peut être réduite à un minimum et un changement de canal rapide pour un utilisateur pour un autre canal dans le même groupe de canaux peut être garanti.
(KO)본 발명은 모바일 IPTV 서비스 제공 방법 및 이를 위한 시스템이 개시된다. 동일한 채널 그룹에 소속된 채널의 스트림을 수신중인 단말에서 수행되는 모바일 IPTV 서비스 제공 방법은, 현재 서비스 제공 중인 채널과 상기 선택된 채널이 동일한 채널 그룹에 속하는지 판단하는 단계 및 상기 판단 결과 동일한 채널 그룹에 속하는 경우, 상기 단말이 수신중인 채널의 스트림에서 상기 선택된 채널의 IPTV 채널 스트림을 디코딩하는 단계를 포함하여 구성될 수 있다. 따라서, 동일한 채널 그룹내의 다른 채널로 채널을 변경할 시 평균 처리 복잡도를 최소화하고 사용자의 빠른 채널 변경을 보장할 수 있다.
