Abstract

La présente invention concerne le domaine technique de la diffusion en continu en direct de réseau, et concerne en particulier un procédé, un dispositif et un appareil terminal de commande permettant de synthétiser un flux vidéo d'une salle de diffusion en continu en direct. Le procédé comprend les étapes consistant : à afficher une ou plusieurs commandes vidéo correspondant au nombre de deuxièmes flux vidéo ; à recevoir, en réponse à au moins une instruction de sélection agissant sur les commandes vidéo, un deuxième flux vidéo correspondant à une commande vidéo sélectionnée, et à synthétiser, à l'aide d'une disposition spécifiée, ledit deuxième flux vidéo et un premier flux vidéo capturé localement au sein d'un troisième flux vidéo ; et à télécharger en amont le troisième flux vidéo sur un serveur, de telle sorte que le serveur pousse le troisième flux vidéo vers chaque utilisateur dans la salle de diffusion en continu en direct. En configurant un terminal diffuseur en tant que terminal serveur, la présente invention réduit l'utilisation de largeur de bande, et réduit une charge de travail d'un serveur de plateforme de diffusion en continu en direct. De plus, en sélectionnant, de différentes manières, un deuxième flux vidéo connecté dans un mode de diffusion en continu en direct multi-source, la présente invention améliore l'interaction entre un diffuseur et un utilisateur pour créer une atmosphère vivante dans une salle de diffusion en continu en direct, et améliore la présentation du contenu de diffusion en continu en direct dans un mode de diffusion en continu en direct multi-source au public aux utilisateurs de la salle de diffusion en continu en direct.
