Abstract
Provided is an image transmission apparatus in digital TV broadcasting, including: a first converter which converts added data, which are to be inserted into an image, into a pixel block; a border extender which adds an extended border area to an image area to extend the image in video data and inserts the converted added data into the extended border area; a video encoder which encodes the video data into which the border extender inserts the added data; a video decoder which decodes the video data encoded by the video encoder; and a second converter which converts the added data which are inserted as a pixel block in the video data decoded by the video decoder into original data. Accordingly, in digital TV broadcasting such as HD TV an UDTV, the added data are inserted into a hidden area, so that it is possible to transmit various types of information including contents and copyright without a deterioration in image quality.
