Abstract: Disclosed is an encoder which receives first to third input frames included first intra period and outputs a bitstream corresponding to the third input frame. The encoder includes a motion compensation unit that generates a first reference frame corresponding to the first input frame and a second reference frame corresponding to the second input frame, a union operation unit that generates an overlap frame by performing a union operation based on the first reference frame and the second reference frame, and an inter prediction unit that generates an occupancy code by performing an inter prediction operation on the overlap frame and the third input frame. In this case, the bitstream includes the occupancy code.

Abstract: A content joint editing method according to an embodiment of the inventive concept may preserve the real-time property of update of edits as much as possible even if the number of editors increases when multiple editors simultaneously edit content. A content editing method can share and edit various contents without calling a separate external application in an online collaboration service. A content sharing method can manage each user's access rights to a content in individual content units in collaboration service that displays a plurality of contents at the same time in the collaboration space for sharing contents among multiple users.
