| Abstract(in English) | The arithmetic coding is known as a highly efficient entropy coding. However, the arithmetic coding process is time-consuming due to the symbol-by-symbol arithmetic operations. L-R coder and Q-coder have been proposed to reduce the computation time by replacing the multiplication with the addition, subtraction or shift operation. However, these approximations cause a loss of the coding efficiency. In this paper, we propose a fast arithmetic coding using source expansion and previous computation of probability look-up tables. The simulation result shows that the proposed encoding and decoding method are faster than the conventional arithmetic coding. |
