Display apparatus, controlling method thereof and controlling method of display system

A first display apparatus, comprising:

• an interface configured to connect to an external storage medium;
• a communicator configured to perform communication with a second display apparatus;
• a display configured to reproduce image contents;
• and
• a controller configured to, in response to the display apparatus being set as a master device according to setting information input from the external storage medium, control the display to transmit reproduction time information of image contents to the second display apparatus, synchronize the second display apparatus with the first display apparatus with respect to the image contents, and reproduce the synchronized image contents.

A method for controlling a plurality of display apparatuses, comprising:

• connecting each of the plurality of display apparatuses to an external storage medium including setting information through a communications network;
• reproducing image contents by each of the plurality of display apparatuses;
• transmitting, by one of the plurality of apparatuses set as a mater device according to the setting information, reproduction time information with respect to the image contents to at least another one of the plurality of apparatuses through the communications network;
• and
• synchronizing the image contents reproduced by the plurality of display apparatuses according to the time information.

A method of reproducing a moving image by a display apparatus, the method comprising:

• determining the display apparatus as a master device based on connection setting information;
• transmitting the connection setting information to slave devices;
• transmitting an image reproduction command and synchronization time information to the slave devices in response to connection request being received from the slave devices;
• dividing the image into a plurality of sub-images based on the number of the slave devices;
• and
• reproducing one of the plurality of sub-images according to the synchronization time information.
