Abstract: A screen image encoding method includes: obtaining and storing one or more candidate blocks, which are spatially co-located with a current block, from images encoded prior to a current image; determining whether a reference block used to encode the current block exists in the stored one or more candidate blocks; and encoding at least one of index information indicating the reference block, prediction information used to encode the current block from the reference block, and information about the current block, based on a result of the determining.

Abstract: Provided is a method, performed by a terminal, of providing content includes determining whether at least one content is included in preference content, based on information about the at least one content provided to the terminal and preference information of a user of the terminal about content; content, which is not included in the preference content, is present in the at least one content, transmitting, to a server, a request to change the first content to second content included in the preference content based on previously stored information about the preference content; and outputting the second content received from the server, in response to the request.
