Abstract: front page image
(EN)The present invention relates to a P2P live streaming system, and more specifically to a P2P live streaming system that can stably transmit a real-time broadcast to many viewers within a P2P network. The present inventive system comprises: a streaming server for splitting an original stream transmitted from a broadcasting client into at least two sub-streams and transmitting the sub-streams to a viewing network by channel; and a relay server for providing channel allocation information to the streaming server in order to support the split transmission of sub-streams, and for providing each viewing client of the viewing network with sub-stream access information of every channel to be able to recover the original stream.
(FR)La présente invention concerne un système de diffusion en flux continu en direct de type P2P (poste à poste) et plus précisément, un système de diffusion en flux continu en direct de type P2P pouvant transmettre de manière stable une diffusion en temps réel destinée à de nombreux téléspectateurs sur un réseau de type P2P. Le système de la présente invention comprend un serveur de diffusion en flux continu destiné à séparer un flux d'origine transmis par un client de diffusion en au moins deux flux secondaires et à transmettre les flux secondaires à un réseau de visionnement sur un canal ; et un serveur relais destiné à fournir des informations d'allocation de canal au serveur de diffusion en flux continu afin de prendre en charge la transmission séparée de flux secondaires, et à fournir à chaque client de visionnement du réseau de visionnement des informations d'accès aux flux secondaires de chaque canal afin qu'il soit en mesure de récupérer le flux d'origine.
(KO)본 발명은 P2P 라이브 스트리밍 시스템에 관한 것으로, 보다 상세하게는 이를 통해 실시간 방송을 P2P 네트워크 내 다수의 시청자에게 안정적으로 전송할 수 있게 된다. 이와 같은 본 발명은 방송 클라이언트로부터 전송되는 원본 스트림을 적어도 둘 이상의 서브 스트림으로 분할하여 시청 네트워크에 채널별로 전송하는 스트리밍 서버와, 상기 스트리밍 서버에 채널 할당 정보를 제공하여 서브 스트림의 분할 전송을 지원하고, 상기 시청 네트워크의 각 시청 클라이언트들에게 원본 스트림을 복원할 수 있는 모든 채널의 서브 스트림 접속 정보를 제공하는 릴레이 서버를 포함한다.
