The subscriber profile server 40 stores a subscriber profile including gender and age information of the mobile communication service subscriber, and provides the content selector 34 with the gender and age of the sender.

The content selection unit 34 checks whether the sender's gender and age are received from the subscriber profile server 40 (S6), and if the subscriber profile information of the caller is not stored in the subscriber profile server 40, the image analysis is performed. In section 33, the caller's face image is analyzed.

In this case, the image analyzer 33 analyzes the face image of the caller received by the transceiver 32 to recognize the gender and age of the caller. For example, in one embodiment of the present invention, the image analyzer 33 may detect the wrinkle vector in the caller's face image, and classify the age of the caller according to the number of detected wrinkle vector. In addition, the image analyzer 33 may detect the sender's gender by detecting the outline vector of the head portion in the caller's face image and comparing the preset outline vector with each gender outline vector. The gender and age information of the sender detected by the image analyzer 33 is transmitted to the content selector 34.

The content selection unit 34 selects the multimedia content corresponding to the sender's gender and age by using the sender's gender and age information received from the subscriber profile server 40 or detected by the image analyzer 33. (S8). The selection of the content selection unit 34 is performed according to the multimedia content according to the gender and age of the caller stored in the storage unit 31 by the called party in step S1. By the above-described process, the content selection unit 34 may select multimedia content suitable for the gender and age of the sender.

In an embodiment of the present invention, when one or more multimedia contents corresponding to the gender and age of the caller are selected as a result of the selection of the content selecting unit 34, the content selecting unit 34 is previously transmitted among the plurality of selected multimedia contents. It is also possible to reselect the multimedia content having a tendency opposite to the tendency of the basic multimedia content (S9). For example, when the basic multimedia content already transmitted to the calling terminal 20 has a high average volume, the content selection unit 34 may preferentially select the multimedia content having the lowest average volume.

The content selector 34 transmits the selected multimedia content to the transceiver 32, and the transceiver 32 transmits the selected multimedia content to the calling terminal 20 (S10). The multimedia content transmitted to the calling terminal 20 is changed by the above-described process, and the caller does not have to suffer the inconvenience of continuing to watch the multimedia content that does not suit his or her taste.

Using the above-described apparatus and method for transmitting multimedia content according to the present invention, if it is determined that the caller's facial expression watching the preset multimedia content is negative, such as a sad or unpleasant facial expression, the multimedia content suitable for the gender and age of the caller is obtained.
