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.

Description

technical field [0001] The invention relates to an image transmission device for digital television broadcasting, in particular to a scheme for transmitting copyright and additional data by utilizing the field hidden in digital television broadcasting. Background technique [0002] The digital broadcasting system processes the entire process into a digital signal with clear picture quality and subdivides it into audio signals from the bass range to the treble range, thereby enabling high sound quality. Therefore, the digital broadcasting system is rapidly applied and disseminated through various media such as ground wave, satellite, and cable TV. [0003] For ground wave digital broadcasting, the 8VSB transmission system adopted the 1995 standard in the United States, and broadcast trials have been carried out since the second half of 1998. South Korea has also adopted the ground wave digital broadcasting standard based on the US method for broadcasting. [0004] Digital br...
