Title (EN) ADAPTIVE BITRATE IMAGE SERVICE METHOD
(FR) PROCÉDÉ DE SERVICE D'IMAGE À DÉBIT BINAIRE ADAPTATIF
(KO) 적응적 비트레이트 영상 서비스 방법
Abstract:
(EN) Disclosed is an adaptive bitrate image service method. The image service method, according to one aspect of the present invention, executed at an image-providing device connected with a user terminal via a communication network, comprises the steps of: encoding a video being serviced into multiple bitrates; when a request for the video being serviced is received from the user terminal, determining a service method corresponding to the communication bandwidth for the user terminal, and selecting the video being serviced that is encoded into a bitrate corresponding to the service method; providing the selected video being serviced to the user terminal; and in order to determine the next service method to be provided to the user terminal in the future, storing a history of the videos being serviced that were provided so as to correspond to the user terminal.
(FR) L'invention concerne un procédé de service d'image à débit binaire adaptatif. Selon un aspect de la présente invention, le procédé de service d'image exécuté au niveau d'un dispositif de fourniture d'image connecté à un terminal utilisateur par l'intermédiaire d'un réseau de communication comprend les étapes consistant à : coder une vidéo étant desservie en de multiples débits binaires ; lorsqu'une demande de la vidéo étant desservie est reçue en provenance du terminal utilisateur, déterminer un procédé de service correspondant à la bande passante de communication du terminal utilisateur, et sélectionner la vidéo étant desservie qui est codée en un débit binaire correspondant au procédé de service ; fournir la vidéo sélectionnée étant desservie au terminal utilisateur ; et afin de déterminer le procédé de service suivant devant être fourni au terminal utilisateur à l'avenir, stocker un historique des vidéos étant desservies qui ont été fournies de façon à correspondre au terminal utilisateur.
(KO) 적응적 비트레이트 영상 서비스 방법이 개시된다. 본 발명의 일측면에 따른 사용자 단말과 통신망을 통해 결합된 영상 제공 장치에서 수행되는 영상 서비스 방법은, 서비스 동영상을 복수개의 비트레이트로 인코딩하는 단계; 서비스 동영상에 대한 요청이 사용자 단말로부터 수신되면, 사용자 단말과의 통신 대역폭에 상응하는 서비스 방식을 결정하고, 서비스 방식에 따른 비트레이트로 인코딩된 서비스 동영상을 선택하는 단계; 선택된 서비스 동영상을 사용자 단말로 제공하는 단계; 및 사용자 단말로 차후 제공할 차기 서비스 방식을 결정하기 위해, 사용자 단말에 대응되도록 서비스 동영상의 제공 이력을 저장하는 단계를 포함한다.
