Abstract

Des modes de réalisation de la présente invention concernent un procédé, un appareil, et un système de diffusion vidéo en direct. Dans le procédé selon la présente invention, un serveur : reçoit une demande de diffusion en direct qui est envoyée par un premier terminal à un second terminal pour obtenir une vidéo en temps réel sur site du second terminal, la demande de diffusion en direct contenant l'identité du second terminal ; transmet la demande de diffusion en direct au second terminal, d'après l'identité ; reçoit un signal de réponse et un second flux vidéo, du second terminal, le signal de réponse étant un signal de réponse du second terminal à la demande de diffusion en direct, le second flux vidéo étant le flux vidéo obtenu par conversion de la vidéo en temps réel sur site enregistrée par le second terminal ; et transfère le signal de réponse et le second flux vidéo au premier terminal, de sorte que le premier terminal peut afficher la vidéo en temps réel sur site du second terminal à l'extérieur au moyen d'un écran d'affichage. Par rapport à l'état de la technique, la présente invention peut satisfaire davantage de demandes d'utilisateur sur la communication en réseau de tapis roulants.
