Title (EN) ELECTRONIC DEVICE, IMAGE PROCESSING METHOD THEREOF, AND NON-TRANSITORY COMPUTER READABLE RECORDING MEDIUM
(FR) APPAREIL ÉLECTRONIQUE, PROCÉDÉ DE TRAITEMENT D'IMAGE ASSOCIÉ, ET SUPPORT D'ENREGISTREMENT NON-TRANSITOIRE LISIBLE PAR ORDINATEUR
Abstract:
(EN) An electronic device, an image processing method thereof, and a non-transitory computer readable recording medium are provided. The image processing method for the electronic device includes receiving an image signal; extracting, by a middleware layer, an entitlement management message (EMM) from the image signal; transmitting the extracted EMM to a web browser based application of an application layer; confirming, by the application, a user authority using the extracted EMM; extracting, by the middleware layer, a control word (CW) if the authority for the image signal is confirmed; and descrambling the image signal using the extracted control word.
(FR) L'invention concerne un dispositif électronique, un procédé de traitement d'image associé et un support d'enregistrement non transitoire lisible par ordinateur. Le procédé de traitement d'image pour le dispositif électronique consiste à : recevoir un signal d'image ; extraire, par une couche d'intergiciel, un message de gestion de droit (EMM) à partir du signal d'image ; transmettre l'EMM extrait à une application basée sur un navigateur web d'une couche d'application ; confirmer, par l'application, une autorité d'utilisateur à l'aide de l'EMM extrait ; extraire, par la couche d'intergiciel, un mot de commande (CW) si l'autorité pour le signal d'image est confirmée ; et désembrouiller le signal d'image à l'aide du mot de commande extrait.
