Abstr act.High computation complexity has significantly impacted H.264/AVC's application and promotion in real-time coding.As a result, how to reduce as much computation complexity as possible while ensuring high coding efficiency becomes an important subject in the study of video coding technology.Many scholars started their study from prediction of all-zero residual blocks to reduce the overhead of DCT, IDCT, quantization and inverse quantization, thus reduced the overall computation complexity.This paper analyzes the statistics of residual coefficient distribution based on the H.264 video coding standard, put forward a
