Abstract

La présente invention se rapporte au domaine de la technologie des réseaux. La présente invention porte sur un procédé et sur un dispositif de diffusion vidéo, le procédé consistant : à acquérir une première trame vidéo capturée par une caméra avant et une seconde trame vidéo capturée par une caméra arrière ; à synthétiser la première trame vidéo et la seconde trame vidéo pour acquérir une trame vidéo cible ; et à envoyer la trame vidéo cible à un serveur de sorte à permettre au serveur de transmettre la trame vidéo cible à un terminal de visualisation. Au moyen de la caméra avant et de la caméra arrière, à la fois un écran hôte et un écran d'environnement peuvent être représentés en même temps, surmontant le défaut selon lequel un hôte ne peut pas montrer l'environnement tout en voulant se montrer, ou ne peut pas se montrer tout en souhaitant montrer l'environnement, ce qui permet d'obtenir un effet de diffusion souhaitable et un taux de rétention d'utilisateur élevé.
