  • Encoding apparatus and method, recording medium, and decoding apparatus and method
    Patent number: 6518891
    Abstract: The first codec-based dummy string generator 132 generates a first code-cbased dummy string in a first code string conforming to a first format based on the first coding method. The second codec encoder 131 generates a second code string having been encoded with a higher efficiency than the first code string and conforming to a second format different from the first format. The code string generator 133 generates a synthetic code string by embedding the second codec-based code string generated by the second codec encode block 131 in a blank area formed in the first code string based on the first codec-based dummy string generated by the first code dummy string generator 132.
