Abstract: Methods and apparatus are provided for generating an animated message. Input objects in an image of the animated message are recognized, and input information, including information about an input time and input coordinates for the input objects, is extracted. Playback information, including information about a playback order of the input objects, is set. The image is displayed in a predetermined handwriting region of the animated message. An encoding region, which is allocated in a predetermined portion of the animated message and in which the input information and the playback information are stored, is divided into blocks having a predetermined size. Display information of the encoding region is generated by mapping the input information and the playback information to the blocks in the encoding region. An animated message including the predetermined handwriting region and the encoding region is generated. The generated animated message is transmitted.
