1. A method for decoding an input bitstream, comprising:

  • receiving an input bitstream that contains compressed coded data obtained by encoding a visual object by performing at least one of a plurality of different operations which can be performed on a block by block basis, said input bitstream further containing a descriptor capable of including information of a respective parameter related to the number of times that each of said operations was performed in a unit of blocks, said descriptor associated with a complexity of decoding the compressed coded data;

    extracting the descriptor from the input bitstream; and

    decoding the compressed coded data.
