Embodiments of the present invention relate to the technical field of streaming media and provide a streaming media transmitting method, device and system, which can dynamically adjust the streaming media transmitting manner in order to adapt to the change of a use state of a terminal, thereby avoiding the waste of bandwidth resources and network traffic, and improving user experience. The method comprises: receiving a play state parameter reported by a terminal; obtaining streaming media information according to the play state parameter; and sending the obtained streaming media information to the terminal. The embodiments of the present invention are used for streaming media transmission.

Des modes de réalisation de la présente invention concernent le domaine technique de la transmission multimédia en continu et concernent un procédé, un dispositif et un système de transmission multimédia en continu permettant d'ajuster dynamiquement la méthode de transmission multimédia en continu afin de l'adapter à un changement d'état d'utilisation d'un terminal, pour ainsi éviter un gaspillage de ressources de bande passante et de trafic sur le réseau et d'améliorer le confort des utilisateurs. Le procédé consiste : à recevoir un paramètre d'état de lecture signalé par un terminal ; à obtenir des informations de transmission multimédia en continu en fonction du paramètre d'état de lecture ; et à envoyer au terminal les informations de transmission multimédia en continu obtenues. Les modes de réalisation de la présente invention sont utilisés pour la transmission multimédia en continu.
