1. A method of losslessly coding coefficients included in a block of a fine granularity scalability (FGS) layer constituting a video signal having a multi-layer structure, the method comprising:

  • extracting non-unitary coefficients of the block that have absolute values that are not 0 or 1;

    calculating a representative value from run values of the non-unitary coefficients which are extracted;

    comparing the run values of the non-unitary coefficients of the block and the representative value; and

    assigning codewords to the non-unitary coefficients according to a result of the comparing.
