<p>Disclosed is a data transfer apparatus and a method using a USB module. The data transfer apparatus includes a storage for storing an image data provided from a predetermined image source; a user input unit through which a user requests to transfer the stored image data to an external host; an image coder for generating a base layer having a low frequency signal less than a predetermined frequency and a plurality of upper layers having a high frequency signal greater than the predetermined frequency, and coding the base layer and the upper layers; a communication module for transferring the coded base layer and upper layers to the external host, each in different transfer mode; and a main controller for controlling the communication module, if the user makes a transfer request through the user input unit, and thereby transferring the base layer and the upper layers to the external host. Therefore, by transferring the base layer in bulk transfer mode, it is possible to minimize a transfer error rate.</p> |
