Abstract
(EN) Disclosed in the present application are a video transmission method, a mobile platform, a terminal device, and a storage medium. The method comprises: transmitting, to a terminal device by means of a first wireless communication mode, first video frames obtained by encoding (S101); obtaining a reference video frame (S102); and transmitting, to the terminal device by means of a second wireless communication mode, a second video frame obtained by encoding a target video frame on the basis of the reference video frame (S103). The present application improves the wireless image transmission quality of the mobile platform.
(FR) Un procédé de transmission vidéo, une plateforme mobile, un équipement terminal et un support d'enregistrement sont divulgués dans la présente invention. Le procédé consiste à : transmettre, à un équipement terminal au moyen d'un premier mode de communication sans fil, des premières images vidéo obtenues par codage (S101) ; obtenir une image vidéo de référence (S102) ; et transmettre, à l'équipement terminal au moyen d'un second mode de communication sans fil, une seconde image vidéo obtenue par codage d'une image vidéo cible sur la base de l'image vidéo de référence (S103). La présente invention améliore la qualité de transmission d'images sans fil de la plateforme mobile.
