PURPOSE: A bookmarking method using thumbnail is provided to confirm stored contents through a thumbnailed picture without reproducing the stored contents. CONSTITUTION: A digital television receiver receives a broadcasting stream of contents a user requests(s301). A thumbnail picture is extracted from the received broadcasting stream and indexed(s303,s305). When a bookmarking request message is transmitted from the user(s307), the latest thumbnail picture among thumbnail pictures extracted before the bookmarking request message is received is bookmarked and added to a recording list(s309). The recording list is displayed at the request of the user(s311). When a message of requesting contents included in the recording list to be reproduced is received from the user(s315), it is confirmed if a bookmarking index is detected from the contents(s317). When the bookmarking index is detected, the bookmarked thumbnail picture is provided to the user(s319).
