초록
In this paper, we present the method of skipping the quantization for fast video encoding. Based on the theoretical analyzes for the integer transform and quantization in H.264 video coder, we can derive a sufficient threshold under which each quantized coefficient becomes zero. In addition, in order to reduce the complexity of the fast video encoding, complexity is improved, leading to improvement of total encoding time saving for given threshold. The simulation results show the capability of the proposed algorithm.
