AVN system having function of analyzing mirroring data and method of controlling mirroring data

A method of controlling mirroring data in an AVN (Audio, Video, and Navigation) system of a vehicle, configured to provide functions of audio, video, and navigation, the AVN system comprising a processor including a receiving unit, a determining unit, a control unit, and an output unit, the method comprising:

• receiving, by the receiving unit, driving information of the vehicle from the vehicle;
• receiving, by the receiving unit, mirroring data from an external wireless terminal through a wireless communication;
• determining, by the determining unit, whether or not the vehicle is moving, based on the driving information;
• determining, by the determining unit, a type of the mirroring data, wherein the type of the mirroring data is movie data or non-movie data;
• controlling, by the control unit, including
• when the vehicle is not moving, outputting the mirroring data to the AVN regardless of the type of the mirroring data, and
• when the vehicle is moving, outputting the mirroring data to the AVN only when the type of the mirroring data is the non-movie data;
• and
• outputting, by the output unit, the mirroring data to a display device, wherein
• the determining includes
• detecting an amount of change of the mirroring data per unit time,
• comparing the amount of change of the mirroring data per unit time with a predetermined threshold value, and
• determining that the mirroring data are movie data when the amount of change of the mirroring data is larger than the threshold value.
