Abstract: Provided is a display device including: a display; a communicator; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory, to perform control to extract a video fingerprint from current content being displayed on the display, transmit the extracted video fingerprint to a server, receive, from the server, a first response comprising a matching result of the extracted video fingerprint and video fingerprints stored in the server, extract an audio fingerprint from the current content being displayed on the display in case that the extracted video fingerprint matches a plurality of video fingerprints stored in the server according to the first response, transmit the extracted audio fingerprint to the server, and receive, from the server, a second response comprising a matching result of the extracted audio fingerprint and audio fingerprints stored in the server.

Abstract: An electronic apparatus includes a communication interface, a display, and a processor configured to, based on a content being received from a source apparatus via the communication interface, obtain feature information of the received content, and transmit the obtained feature information to an external server, receive, from the external server, identification information of the content, the identification information being obtained based on the transmitted feature information, based on a predetermined mode of the display being turned on according to a signal that is received from the source apparatus via the communication interface, obtain information regarding a first time point when the predetermined mode is turned on, and based on the predetermined mode of the display being turned off, obtain information regarding a second time point when the predetermined mode is turned off after the first time point.

Abstract: An electronic apparatus and a method of controlling the same are provided. The electronic apparatus includes a communication interface and a processor configured to receive multimedia data from an external apparatus, obtain a first finger print of first frames among a plurality of frames included in the multimedia data, the first frames being included in a first time interval, and transmit the first finger print to the server; identify whether a content in the multimedia data has been changed and a time point indicating a time of identifying a change in the content; based on identifying that the content has been changed, obtain a second finger print of a frame corresponding to the time point, and transmit the second finger print to the server; receive content information corresponding to the second finger print, and determine whether to change the first time interval based on the content information.
