Abstract
(EN)
A method by which a cloud streaming server recovers a user interface (UI) session, according to one embodiment of the present invention, can comprise the steps of: establishing a first user interface session between a cloud streaming server and a client terminal in order to stream a user interface image to the client terminal; establishing a video session between the cloud streaming server and the client terminal in order to stream video content to the client terminal; releasing the first user interface session in a state, in which the video session is maintained, according to the satisfaction of a preset session release condition; and establishing a second user interface session between the cloud streaming server and the client terminal according to the satisfaction of a preset session recovery condition.
