ABSTRACT:
A transmitting device includes a main image generation unit generating a main image by overlaying first overlay data over an original image; an extraction unit extracting, from the original image, a partial image of a portion over which the first overlay data is overlaid; a first sub-image generation unit generating a first sub-image by overlaying second overlay data over the partial image; and encoding units and a multiplexing unit generating transmitted data by associating the main image and the first sub-image, and associating the main image with a broadcast time of the main image. Thus, the present invention provides a transmitting device, a reconstruction device, a transmitting method and a reconstruction method for broadcasts with hidden subtitles, having good operability for the viewer.
