Abstract

La présente invention concerne un procédé d'envoi, d'acheminement et de transmission de données, et un appareil d'envoi, d'acheminement et de transmission de données. Le procédé d'envoi de données consiste à : déterminer, d'après une instruction de transmission de données, des données devant être transmises, qui doivent être envoyées, et un terminal cible pour recevoir les données devant être transmises ; charger les données devant être transmises vers l'amont, sur un serveur, et recevoir des informations codées des données devant être transmises, retournées par le serveur ; et envoyer les informations codées et les informations d'adresse du serveur au terminal cible, de sorte que le terminal cible obtienne, du serveur, des données devant être transmises correspondant aux informations codées, d'après les informations d'adresse. Selon la solution technique décrite dans les modes de réalisation de l'invention, le serveur achemine les données devant être transmises, envoyées par un dispositif interactif, à une extrémité de réception de données. De la sorte, l'occupation de ressources de communication entre le dispositif interactif et le terminal cible pendant un processus de transmission de données peut être réduite, et la stabilité de flux vidéo transmis au dispositif interactif par le terminal cible est améliorée.
