Abstract
(EN)
The present invention relates to a system for a cloud streaming service, a method for a still image-based cloud streaming service and an apparatus therefor. The still image-based cloud streaming service can be provided by capturing the changed area in the changed frame by comparing same with the previous frame, selecting a still-image compression technique by considering any one or more from among the size of the changed area and image characteristics, and transmitting, to a user, the changed area encoded by the still-image compression technique. When providing a still image-based cloud streaming service, by utilizing still-image compression techniques which are appropriate to the conditions, the compression efficiency of the still image and speed of the cloud streaming service can be improved.

La présente invention concerne un système destiné à un service de diffusion en continu en nuage, un procédé destiné à un service de diffusion en continu en nuage à base d'image fixe et un appareil associé. Le service de diffusion en continu en nuage à base d'image fixe peut être réalisé par acquisition de la zone modifiée dans la trame modifiée en comparant cette dernière à la trame précédente, en sélectionnant une technique de compression d'image fixe en tenant compte de l'un ou l'autre ou de plusieurs éléments parmi la taille de la zone modifiée et des caractéristiques d'image, et en transmettant à un utilisateur la zone modifiée codée par la technique de compression d'image fixe. Lors de la fourniture d'un service de diffusion en continu en nuage à base d'image fixe, en utilisant des techniques de compression d'image fixe qui sont adaptées aux conditions, il est possible d'améliorer l'efficacité de compression de l'image fixe et la vitesse du service de diffusion en continu en nuage.

본 발명은 클라우드 스트리밍 서비스 시스템, 스틸 이미지 기반 클라우드 스트리밍 서비스 방법 및 이를 위한 장치가 개시된다. 이전 프레임과 비교하여 변화된 프레임에 포함된 변화 영역을 캡처하고, 변화 영역의 사이즈 및 이미지 성질 중 어느 하나 이상을 고려하여 스틸 이미지 압축 기법을 선택하고, 스틸 이미지 압축 기법으로 인코딩한 변화 영역을 사용자에게 전송하여 스틸 이미지 기반의 클라우드 스트리밍 서비스를 수행할 수 있다. 스틸 이미지 기반 클라우드 스트리밍 서비스 제공 시 상황에 적합한 스틸 이미지 압축 기법을 사용함으로써 스틸 이미지의 압축 효율과 클라우드 스트리밍 서비스의 속도를 향상시키는 것이 가능하다.
