Summary:A method for sharing contents between remotely located DLNA devices according to an embodiment comprises: multicasting a message for searching for a device for performing a DLNA function at a first DLNA device; packing the multicasted message in a TCP/IP packet; sending the packed message to another network connected to the first DLNA device via a virtual private network; receiving the packed message at the another network; changing the sender IP of the packed message to the IP of the first DLNA device; and multicasting a message including the changed IP to DLNA devices within the network, thereby allowing the first DLNA device to share contents with DLNA devices receiving the multicasted message. L'invention concerne un procédé de partage de contenus entre dispositifs DLNA distants, qui comporte, selon un mode de réalisation, les étapes consistant à: émettre en diffusion groupée un message visant à rechercher un dispositif pour réaliser une fonction de DLNA au niveau d'un premier dispositif DLNA; condenser le message émis en diffusion groupée dans un paquet TCP/IP; envoyer le message condensé à un autre réseau relié au premier dispositif DLNA via un réseau privé virtuel; recevoir le message condensé au niveau de l'autre réseau; modifier l'adresse IP d'expéditeur du message condensé en adoptant l'adresse IP du premier dispositif DLNA; et émettre en diffusion groupée un message comprenant l'adresse IP modifiée vers des DLNA dispositifs au sein du réseau, permettant ainsi au premier dispositif DLNA de partager des contenus avec des dispositifs DLNA recevant le message émis en diffusion groupée. 실시 형태에 따른 원거리에 위치한 DLNA 장치들 사이의 콘텐츠 공유 방법은 제 1 DLNA 장치에서 DLNA 기능을 수행하기 위한 장치를 검색하기 위한 메시지를 멀티캐스트 하고, 멀티캐스트된 메시지를 TCP/IP 패킷으로 포장하며, 포장된 메시지를 제 1 DLNA 장치와 가상 사설망으로 연결된 다른 망으로 전송하고, 다른 망에서 포장된 메시지를 수신하고, 포장된 메시지의 전송자 IP를 제 1 DLNA 장치의 IP로 변경하고, 변경된 IP를 포함하는 메시지를 망 내의 DLNA 장치들로 멀티캐스트한 후, 제 1 DLNA 장치는 멀티캐스트된 메시지를 수신하는 DLNA 장치와 콘텐츠를 공유할 수 있다.
