Abstract
(EN)
Disclosed are a video transmission method and apparatus, and an aircraft, a playback device, and a storage medium. The method comprises: obtaining the current image frame, encoding the current image frame, and then sending the encoded current image frame to a receiving terminal (S110); if error feedback information sent by the receiving terminal is received, determining an error correction refreshing frame according to the current image frame (S120); and performing intra-frame encoding on a partial region of the error correction refreshing frame, and sending the encoded error correction refreshing frame to the receiving terminal (S130), so as to enable a transmission error to recover faster.
(FR)
L'invention concerne un procédé et un appareil de vidéotransmission ainsi qu'un aéronef, un dispositif de lecture et un support de stockage. Le procédé consiste à : obtenir l'image courante, coder l'image courante, puis envoyer l'image courante codée à un terminal récepteur (S110) ; si des informations de rétroaction d'erreur envoyées par le terminal récepteur sont reçues, déterminer une image de rafraîchissement à correction d'erreur en fonction de l'image actuelle (S120) ; et réaliser un codage intra-image sur une région partielle de l'image de rafraîchissement à correction d'erreur, et envoyer l'image de rafraîchissement à correction d'erreur codée au terminal récepteur (S130), de façon à permettre d'effectuer plus rapidement une reprise sur erreur de transmission.
