1. A coded image data-decoding apparatus, comprising:

  • a receiver for receiving coded image data and input information associated with a decoding algorithm for decoding the coded image data;

    a storage device for storing functional tools with their corresponding identifiers;

    a selector for selecting one of the stored functional tools based on the input information associated with the decoding algorithm; and

    a decoder for decoding input coded image data by applying the decoding algorithm comprising the selected functional tools, wherein the information associated with the decoding algorithm is composed of an identifier of a basic decoding algorithm and differential information from the basic decoding algorithm.
