Abstract
(EN)
Disclosed are a quick start method and device for a live video. The method comprises: identifying the type of a current player, and calling a quick start strategy adapted to the type of the current player; when the quick start strategy is executed, reading the current system time and the quick start configuration time corresponding to the current player; determining a quick start index position in a target live video based on the current system time and the quick start configuration time, and determining a key frame index position in the target live video based on the quick start index position; and sending video data in the target live video starting from the key frame index position to the current player, and discarding audio data of the target live video from the key frame index position to the quick start index position. The quick start method and the device can effectively increase the display speed of the first screen of different players.

L'invention concerne un procédé et un dispositif de démarrage rapide d'une vidéo en direct. Le procédé consiste : à identifier le type d'un lecteur en cours, et à appeler une stratégie de démarrage rapide adaptée au type du lecteur en cours ; lorsque la stratégie de démarrage rapide est exécutée, à lire le temps système en cours et le temps de configuration de démarrage rapide correspondant au lecteur en cours ; à déterminer une position d'indice de démarrage rapide dans une vidéo en direct cible en fonction du temps système en cours et du temps de configuration de démarrage rapide, et à déterminer une position d'indice de trame clé dans la vidéo en direct cible en fonction de la position d'indice de démarrage rapide ; et à envoyer des données vidéo dans la vidéo en direct cible à partir de la position d'indice de trame clé vers le lecteur en cours, et à éliminer les données audio de la vidéo en direct cible depuis la position d'indice de trame clé jusqu'à la position d'indice de démarrage rapide. Le procédé et le dispositif de démarrage rapide peuvent augmenter efficacement la vitesse d'affichage du premier écran de différents joueurs.
