Display apparatus and method for controlling thereof

A method of controlling a display apparatus, the method comprising:

• receiving a plurality of different content;
• detecting and processing video data of the plurality of different content;
• receiving the video data to arrange and display the plurality of different content in order to combine the plurality of different content in an image frame;
• signal-processing audio data of the plurality of different content;
• and
• outputting audio signals of the signal-processed audio data to a plurality of eyeglasses apparatuses corresponding to the plurality of different content,
• wherein the signal-processing comprises:
• if audio data of each content processed in the multi-view mode has more than a predetermined number of audio output channels in a multi-view mode operation, signal-processing each audio data to an audio signal of less than the predetermined number of audio output channels.

A eyeglasses apparatus which is interlocked with a display apparatus displaying a plurality of content views, comprising:

• an interface unit which communicates with the display apparatus;
• a first shutter glasses unit;
• a second shutter glasses unit;
• a shutter glasses driver which drives each of the first and the second shutter glasses units based on a sync signal received from the display apparatus;
• a shutter glasses unit which drives a shutter in accordance with the driving signal;
• an input unit which receives a user command to select a content view;
• a controller which, if the user command is input, controls the shutter glasses driver to drive the first and the second shutter glasses units by synchronizing them with a content view selected by the user command from among the plurality of content views;
• and
• an audio output processor which receives an audio signal corresponding to the selected content view and outputs the received audio signal, and
• wherein a number of channels associated with the received audio signal output to the eyeglasses apparatus is less than a number of channels associated with the audio data received by the display apparatus.
