A method and apparatus for generating digital audio signals including images is provided, which can provide audio signals along with images or texts in digital radio broadcasting. The apparatus includes an image format transformer (110) which receives image data and transforms the image data into data having an image input format adequate for video coding; a video coder (120) which receives and codes the transformed image data; an audio coder (130) which receives and codes audio data; and a multiplexer (140) which multiplexes the coded image data and the coded audio data. The apparatus and method can transform image files or text files into data having data formats adequate for video coding, followed by video coding the transformed files, thereby providing image or text data along with audio data in digital radio broadcasting while reducing the cost and time required for generating video content with expensive equipment and facilities. |
