Abstract: front page image
(EN)According to one embodiment of the present invention, a method for transmitting an IPTV streaming service by P2P transmission comprises the steps of collecting TS packets of n skipped units to generate an encapsulation unit for an IPTV streaming service (where n is a natural number); adding an extension header containing type information to the generated encapsulation unit (wherein, said type information is information for identifying the sequence of the encapsulation unit, which is required for decoding the IPTV streaming service); adding an IP header to the encapsulation unit to which the extension header containing the type information is added, in order to generate an IP packet; and transmitting the generated IP packet to at least one super peers.
(FR)Selon un mode de réalisation de la présente invention, un procédé servant à transmettre un service de diffusion en continu IPTV par une transmission P2P comprend les étapes consistant à collecter des paquets TS de n unités sautées pour générer une unité d'encapsulation pour un service de diffusion en continu IPTV (où n est un entier naturel); à ajouter un en-tête d'extension contenant des informations de type à l'unité d'encapsulation générée (lesdites informations de type étant des informations servant à identifier la séquence de l'unité d'encapsulation, qui est nécessaire pour décoder le service de diffusion en continu IPTV); à ajouter un en-tête IP à l'unité d'encapsulation à laquelle l'en-tête d'extension contenant les informations de type est ajouté, afin de générer un paquet IP; et à transmettre le paquet IP généré à au moins un super-poste.
(KO)본 발명의 일실시예에 의한 P2P 전송 방식에 의한 IPTV 스트리밍 서비스를 전송하는 방법은, n개씩 스킵된 단위의 TS 패킷들을 모아서 IPTV 스트리밍 서비스를 위한 인캡슐레이션 유닛(encapsulation unit for IPTV streaming service)를 생성하는 단계와(상기 n은 자연수임), 상기 생성된 인캡슐레이션 유닛(encapsulation unit) 에 타입 정보를 포함하는 익스텐션 헤더(extension header) 를 부가하는 단계(상기 타입 정보는, 상기 IPTV 스트리밍 서비스(streaming service) 를 디코딩 하기 위해 필요한 상기 인캡슐레이션 유닛(encapsulation unit) 의 순서를 식별하는 정보임)와, 상기 타입 정보를 포함하는 익스텐션 헤더(extension header) 가 부가된 인캡슐레이션 유닛(encapsulation unit) 에 IP 헤더(header) 를 부가함으로써, IP 패킷을 생성하는 단계와, 그리고 상기 생성된 IP 패킷을 적어도 하나 이상의 슈퍼 피어(super peer) 에 전송하는 단계를 포함한다.
