Abstract

L'invention concerne un procédé de commande de transmission de données basé sur la voix, un téléviseur intelligent et un support de stockage, le procédé comprenant les étapes suivantes : lors de la confirmation de l'identité d'un utilisateur actuel au moyen d'une reconnaissance vocale, réception de données vocales transmises par une télécommande, sans compression des données ; réalisation d'une reconnaissance vocale en fonction des données vocales, et recommandation de ressources en fonction des caractéristiques de loisirs de l'utilisateur actuel après confirmation de l'identité de l'utilisateur actuel ; et, lors d'une nouvelle réception de données vocales concernant une instruction de commande d'utilisateur actuelle provenant de la télécommande, analyse des données vocales transmises par la télécommande par compression des données, et exécution de l'instruction de commande actuelle. Selon la présente invention, la télécommande est commandée pour commuter entre les modes de transmission sans compression des données et avec compression des données pendant la transmission des données vocales, ce qui résout le problème de la détérioration de la compression audio rendant impossible l'identification précise d'un utilisateur, et améliore la qualité de reconnaissance d'empreinte vocale de la télécommande. Par ailleurs, un contenu audio comportant une grande quantité de données est comprimé puis transmis, ce qui assure une économie d'énergie et la capacité antibrouillage de la télécommande.
