Method of controlling display device for providing content and display device performing the same

A method of controlling a server, the method comprising:

• receiving identification information of a first user from a first device;
• receiving, from a plurality of second devices, identification information of a plurality of second users that are related to the first user and content information corresponding to the plurality of second users;
• calculating a closeness value between the first user identified by the identification information of the first user and the plurality of second user identified by the identification information of the plurality of second users;
• arranging the content information corresponding to the plurality of second user based on the closeness value;
• and
• transmitting the arranged content information corresponding to the plurality of second user and the identification information of the plurality of second users, to the first device,
• wherein the content information comprises information of content that is being displayed on the plurality of second devices respectively corresponding to the plurality of second users, and
• wherein a user interface (UI) by which a user selects content that corresponds to the content information is displayed on the first device, the UI comprising a plurality of objects, each object comprising identification information of one of the plurality of second user and content information corresponding to the one of the plurality of second users, and the plurality of objects are displayed within the UI in order of closeness between the first user and each of the plurality of second users;
• and
• wherein the order of closeness is determined based on comparing a viewing rate referring to a time during which content has been viewed by each of the plurality of second users as compared to a total time of the content.

A first display device comprising:

• a communicator configured to transmit identification information of a first user to a server;
• a controller configured to obtain identification information of a plurality of second users that are related to the first user and content information corresponding to the plurality of second users, from the server, via the communicator, wherein the content information comprises information of content that is being displayed on the plurality of second devices respectively corresponding to the plurality of second users;
• and
• a display configured to display a user interface (UI) for selecting content that corresponds to the content information,
• wherein the controller is configured to control the display, based on an input of the UI, to play the selected content in response to the selecting of the content, and
• wherein the UI comprises a plurality of objects, each object comprising identification information of one of the plurality of second users and content information corresponding to the one of the plurality of second users, and the plurality of objects are displayed within the UI in order of closeness between the first user and each of the plurality of second users;
• and
• wherein the order of closeness is determined based on comparing a viewing rate referring to a time during which content has been viewed by each of the plurality of second users as compared to a total time of the content.

A server comprising:

• a communicator configured to receive, from a first device, identification information of a first user, and configured to receive, from a plurality of second devices, identification information of a plurality of second users that are related to the first user and content information corresponding to the plurality of second users;
• and
• a controller configured to calculate a closeness value between the first user identified by the identification information of the first user and the plurality of second users identified by the identification information of the plurality of second users, and arrange the content information corresponding to the plurality of second users based on the closeness value,
• wherein the communicator transmits the arranged content information corresponding to the plurality of second users and the identification information of the plurality of second users, to the first device, and the content information comprises information of content that is being displayed on the plurality of second devices respectively corresponding to the plurality of second users, and
• wherein the first device displays a user interface (UI) by which a user selects content that corresponds to the content information, the UI comprising a plurality of objects, each object comprising identification information of one of the plurality of second users and content information corresponding to the one of the plurality of second users, and the plurality of objects are displayed within the UI in order of closeness between the first user and each of the plurality of second users;
• and
• wherein the order of closeness is determined based on comparing a viewing rate referring to a time during which content has been viewed by each of the plurality of second users as compared to a total time of the content.

A non-transitory computer-readable recording storage medium having stored thereon a computer program, which when executed by a computer, causes the computer to perform a method comprising:

• transmitting identification information of a first user from a first device to a server;
• obtaining, from the server, identification information of a plurality of second users that are related to the first user and content information corresponding to the plurality of second users, the content information comprising information of content that is being displayed on a plurality of second devices respectively corresponding to the plurality of second users;
• displaying, on the first device, a user interface (UI) for selecting content that corresponds to the content information;
• and
• in response to selecting content using the UI, playing, on the first device, the selected content,
• wherein the UI comprises a plurality of objects, each object comprising identification information of one of the plurality of second users and content information corresponding to the one of the plurality of second users, and the plurality of objects are displayed within the UI in order of closeness between the first user and each of the plurality of second users;
• and
• wherein the order of closeness is determined based on comparing a viewing rate referring to a time during which content has been viewed by each of the plurality of second users as compared to a total time of the content.

A method of controlling a first display device, the method comprising:

• transmitting first user information of a first user to a server;
• receiving, from the server, a plurality of second user information corresponding to a respective plurality of second users who are associated with the first user and a plurality of playback content information of content respectively played by the plurality of second users;
• displaying a user interface (UI) enabling the first user to select content to be played from among the a plurality of content respectively corresponding to the plurality of playback content information;
• playing content selected by the first user via the user interface, wherein the UI comprises playback content identification information and objects for displaying the plurality of second user identification information, and the objects are displayed within the UI in order of closeness between the first user and each of the plurality of second users;
• and
• wherein the order of closeness is determined based on comparing a viewing rate referring to a time during which content has been viewed by each of the plurality of second users as compared to a total time of the content.
