1. A mobile communication terminal which plays multimedia content, comprising:
- a wireless communication unit that transmits/receives voice and data signals through a mobile communication network;
a communication processing unit that processes the voice and data signals transmitted/received through the wireless communication unit;
a voice input/output unit which converts the voice signal processed by the communication processing unit into an audible sound, or which converts a voice signal inputted from the outside and outputs the converted voice signal to the communication processing unit;
a memory unit that stores the content;
a playback unit which checks whether or not elements of content to be played are present in a permanent storage area of the memory unit, loads the elements into a temporary storage area of the memory unit, and, if there is an updated element, loads the updated element into the temporary storage area and plays the updated element;
a display unit that displays an image played by the playback unit;
an audio output unit that outputs an audio signal played by the playback unit; and
an update control unit which is operated upon activation of the playback unit, monitors an occurrence of an event, changes at least one of elements of a played content file to a new element when the event occurs, and notifies the playback unit that the element has been changed.

Abstract
Users desire to add their own produced images to multimedia content, or to update the multimedia content. However, there is a problem in that conventional multimedia content cannot be changed. A mobile communication terminal according to the present invention monitors an occurrence of an event, changes at least one of elements of a played content file to a new element when the event occurs, and plays the content file including the changed element by means of a playback unit. The new element to be changed may be an element received from a storage medium connected on a network, a new file stored in a memory unit, or an image taken by a camera module.
