The method includes obtaining an identifier assigned to the terminal, obtaining a list of one or more contents organized through personalized recommendations for the user, and downloading at least a portion of the one or more contents, in one or more time periods determined based on the identifier, during a pre-download period that is predetermined. ## Claims ### Claim 1 A method of operating a terminal for pre-downloading content ahead of a user's request, the method comprising: obtaining an identifier assigned to the terminal; obtaining a list of one or more contents curated through personalized recommendations for the user; and downloading at least some of the one or more contents in one or more time periods which are determined based on the identifier within a predefined pre-download period. ### Claim 2 (depends on 1) The method of claim 1, wherein the identifier and the list are obtained in an initial configuration procedure following execution of an application installed in the terminal. ### Claim 3 (depends on 1) The method of claim 1, wherein the downloading is initiated without receiving a download request from the user. ### Claim 4 (depends on 1) The method of claim 1, wherein: the time periods include target slots, each determined based on the identifier from among a plurality of slots in each frame of the pre-download period, the downloading comprises switching between a wake-up mode in which pre-downloading is enabled and a sleep mode in which pre-downloading is disabled, based on a wake-up time point and a sleep time point, the sleep time point is set based on an end time point of the target slot in a current frame, and the wake-up time point is set based on a start time point of a target slot of a next frame and whether there is content that has not been completely downloaded by the sleep time point. ### Claim 5 (depends on 4) The method of claim 4, wherein the downloading further comprises: switching to the sleep mode even before the end time point or remaining in the sleep mode even after the start time point, based on whether at least one of a wireless connection status of the terminal, a location of the terminal, or a current time satisfies a predetermined condition. ### Claim 6 (depends on 1) The method of claim 1, further comprising, after the downloading: deleting incomplete content which has not been completely downloaded within the pre-download period. ### Claim 7 (depends on 1) The method of claim 1, further comprising, after the downloading: downloading a remaining portion of incomplete content, which has not been completely downloaded within the pre-download period, in a next pre-download period. ### Claim 8 (depends on 1) The method of claim 1, further comprising, after the downloading: based on whether incomplete content, which has not been completely downloaded within the pre-download period, is selected as playback content, streaming playback of a remaining portion of the incomplete content. ### Claim 9 (depends on 1) A non-transitory computer-readable recording medium storing instructions for causing, when executed by a computer, the computer to perform the method according to claim 1. ### Claim 10 A terminal, comprising: a download policy manager configured to obtain an identifier assigned to the terminal and a list of one or more contents curated through personalized recommendations for a user of the terminal; and a download agent configured to download at least some of the one or more contents in one or more time periods which are determined based on the identifier within a predefined pre-download period.
