  • Image display method, image coding apparatus, and image decoding apparatus
    Patent number: 7925097
    Abstract: An image coding apparatus is provided which satisfies various levels of demands on image distribution, both from image providers and from users. The image coding apparatus includes a coding block which codes predetermined image data. A separation unit separates the coded image data into basic data for reproducing contents of the coded image data as a visible image, and complementary data for complementing the basic data, so that the two pieces of data are distributed on different occasions. An adding unit adds information for independent copyright control to at least either one of the basic data and the complementary data.
