Apparatus and method for casting video data and audio data to web during video telephony in mobile communication terminal

A method for transmitting video telephony data in server during video telephony, the method comprising:

• if authentication information is received from a terminal, determining whether the terminal is subscribed to a transmitting service;
• sending an authentication complete message to the terminal, if the terminal is subscribed to the transmitting service;
• and
• if video telephony data is received from the terminal, transmitting the received video telephony data to another terminal.

An apparatus for transmitting video telephony data during video telephony in a mobile communication terminal, the apparatus comprising:

• a first terminal for sending a transmitting request message to a second terminal if a transmitting request menu is selected in a video telephony mode with the second terminal, sending authentication information to a server if a transmitting accept message is received from the second terminal, and transmitting video telephony data to the server if an authentication complete message is received from the server;
• the second terminal for displaying a transmitting request message through a display unit if the transmitting request message is received from the first terminal in a video telephony mode with the first terminal, and sending the transmitting accept message to the first terminal if a key to accept transmitting request is input;
• and
• a server for determining whether the first terminal is subscribed to the transmitting service if authentication information is received from the first terminal, sending the authentication complete message if the first terminal is subscribed to the transmitting service, and transmitting video telephony data if the video telephony data is received from the first terminal.
