L'invention concerne un procédé de transmission de données, et un dispositif et un support. Le procédé comprend les étapes suivantes : lorsqu'une instruction de transmission de données est reçue, diviser des données d'image en au moins deux segments de données selon des régions d'affichage ; ajouter un identifiant de position à chaque segment de données selon une région d'affichage dans laquelle chaque segment de données est situé ; et envoyer les segments de données avec les identifiants de position ajoutés à une extrémité de dispositif maître. L'invention concerne également un procédé de transmission de données qui est appliqué à une extrémité de dispositif maître. Le procédé comprend les étapes suivantes : recevoir chaque segment de données envoyé d'une extrémité de dispositif ; et charger chaque segment de données dans une région d'affichage correspondante selon un identifiant de position de chaque segment de données. Le problème technique de l'état de la technique selon lequel une vitesse de poussée est relativement lente lorsque toutes les données sont transmises d'un dispositif à un grand écran intelligent pour l'affichage uniforme est résolu. L'effet de chargement et d'affichage rapides ou de lecture de données en segments est réalisé, ce qui améliore l'efficacité et la flexibilité de transmission de données.
