In this paper we propose applying an adaptive context tree weighting method with a forbidden symbol in the H.264 coder. Arithmetic codes with a forbidden symbol and a trellis search techniques are employed on an order to estimate the best transmitted codeword. Instead of using the context modeling defined in the H.264 standard, the arithmetic code with a forbidden symbol uses a ctwmethod. The CABAC algorithm is replaced by GRASP algorithm and the experimental results show that coding gains similar or superior to those obtained with the H.264/AVC CABAC algorithm and arithmetic coding.
