Abstract
Disclosed is a video calling method capable of providing video through a separate display over a VoIP network, which can transfer IP information of a specified display device to a mobile communication terminal, and provide video data transfer for a video call through the specified display device. According to the video calling method, a first mobile communication terminal connects a video calling service with a second mobile communication terminal, and receives a request to change a device for transmitting/receiving the video to/from the second mobile communication terminal to a separate display. The first mobile communication terminal transfers information about the display to the second mobile communication terminal, and controls the second mobile communication terminal to transmit/receive the video to/from the display. The first mobile communication terminal then transfers information about the second mobile communication terminal to the display, and controls the display to transmit/receive the video to/from the second mobile communication terminal.
