Title
(EN) ELECTRONIC DEVICE AND METHOD OF OPERATING THE SAME
(FR) DISPOSITIF ÉLECTRONIQUE ET PROCÉDÉ DE FONCTIONNEMENT ASSOCIÉ
Abstract
(EN) An electronic device and a method of operating the same are provided. The electronic device includes a communication circuit configured to transmit or receive data using a call channel established through a call connection with an external electronic device, and a processor configured to transmit content, which is pre-processed using a first transmission filter, to the external electronic device through the call channel, receive a first real-time control protocol (RTCP) message transmitted by the external electronic device through the call channel, identify a status of the call channel, based on the first RTCP message, determine whether or not to perform an operation of pre-processing the content to be transmitted to the external electronic device using a second transmission filter, transmit a second RTCP message using the second transmission filter to the external electronic device, and perform transmission of the content, based on the second transmission filter.
(FR) La présente invention concerne un dispositif électronique et un procédé de fonctionnement associé. Le dispositif électronique comprend un circuit de communication configuré pour transmettre ou recevoir des données à l'aide d'un canal d'appel établi par l'intermédiaire d'une connexion d'appel avec un dispositif électronique externe et un processeur configuré pour transmettre un contenu, qui est pré-traité à l'aide d'un premier filtre de transmission, au dispositif électronique externe par l'intermédiaire du canal d'appel, pour recevoir un premier message de protocole de commande en temps réel (RTCP) transmis par le dispositif électronique externe par l'intermédiaire du canal d'appel, pour identifier un état du canal d'appel, sur la base du premier message RTCP, pour déterminer s'il faut ou non effectuer une opération de pré-traitement du contenu à transmettre au dispositif électronique externe à l'aide d'un second filtre de transmission, pour transmettre un second message RTCP à l'aide du second filtre de transmission au dispositif électronique externe et pour transmettre le contenu, sur la base du second filtre de transmission.
