摘要

With the advancement of video coding, network technologies and display devices, there appears greater demands for video quality assessment. The pursuit of higher coding efficiency promotes the development of codecs. H.264/AVC standard is the mainstream of video coding standards these days and will not be completely replaced in the near further. Meanwhile, H.265/High Efficiency Video Coding (HEVC) has been promoted by the Joint Collaborative Team on Video Coding (JCT-VC) to achieve higher coding efficiency, and it will own broader prospects in Ultra-High Definition (UHD) video services. H.264/AVC and H.265/HEVC will co-exist, making it crucial to build a reliable VQA model to support both standards at the same time. In this paper, we propose a no reference bitstream-based VQA model that has the compatibility of both H.264/AVC and H.265/HEVC. The proposed model is based on the coding parameters, as well as the display parameters to make it more generalized in diverse terminal display scenarios. The proposed model was validated for both standards using subjective H.264/AVC database and large-scale HEVC database, demonstrating great performance and outperforming other compared models.
