Abstract

L'invention concerne un procédé et un dispositif d'ouverture à distance de transmission de données de flux. Le procédé consiste à : recevoir une première demande d'acquisition de données de flux cibles d'une extrémité d'acquisition distante ; notifier à l'extrémité d'acquisition distante d'acquérir les données de flux cibles et de pousser les données de flux cibles vers un nœud de transmission cible ; et obtenir les données de flux cibles poussées vers le nœud de transmission cible et renvoyer les données de flux cibles à un côté demandeur des données de flux. Un utilisateur expéditeur de la première demande d'acquisition n'est pas limité à un propriétaire de l'extrémité d'acquisition distante, et d'autres utilisateurs peuvent également transmettre une première demande d'acquisition pour réaliser une commande à distance de l'extrémité d'acquisition distante à l'aide d'un équipement terminal, et, par conséquent, le mode de réalisation de l'invention satisfait à la demande de partage de données de flux acquise par une caméra distante. Selon les modes de réalisation de la présente invention, une adresse en flux ouvert d'une extrémité d'acquisition distante, c'est-à-dire une liaison de réseau, peut être partagée avec d'autres utilisateurs, de sorte que d'autres utilisateurs peuvent effectuer une commande en flux ouvert sur l'extrémité d'acquisition distante en accédant à la liaison de réseau et peuvent visualiser des données de flux cibles acquises par l'extrémité d'acquisition distante.
