On the other hand, in most current state-of-the-art early SKIP mode decision methods, the temporal layer index (TId), which is commonly used in the hierarchical coding structure, has not been fully exploited. In this regard, this paper proposes a novel early SKIP mode decision method for a HEVC encoder using TId-based rate-distortion (RD) modeling. In the proposed method, two new SKIP mode-checking conditions were introduced based on statistical analysis on TId and the RD-cost correlation. The experimental results showed that the proposed early SKIP mode decision method outperformed the relevant state-of-the-art HEVC complexity reduction methods significantly, with an encoding time saving of approximately 47% while having a BD-rate loss of only 0.45%.Hoang Van Xiemxiemhoang@vnu.edu.vnDinh Bao Minhminhdinh@vnu.edu.vnJeon Byeungwoobjeon@skku.edu2020-12-08T15:31:09Z2020-12-09T14:58:35Zhttp://eprints.uet.vnu.edu.vn/eprints/id/eprint/4199This item is in the repository with the URL: http://eprints.uet.vnu.edu.vn/eprints/id/eprint/41992020-12-08T15:31:09ZEarly SKIP mode decision for HEVC with Hierarchical coding structureTo meet real-time video communications, an investigation of early SKIP mode decisions is still important in many practical applications of High-Efficiency Video Coding (HEVC) encoders.
