Abstract

The paper presents the study of video data encoding methods by intraframe prediction in N. 265/HEVC standard. A rapid decision-making scheme for intraframe predictions is proposed. According to the proposed scheme the complexity of the texture block coding is firstly calculated and the threshold value for rapid selection of the block coding size is set. That reduces the number of possible prediction modes. The existing and proposed encoding methods were tested on several video sequences by modeling in Visual C++ environment. To evaluate the methods criteria of video sequence quality (PSNR), bitrate and encoding time were used. The results showed that compared with the reference software of HEVC – HM 16.0, the proposed scheme gives the possibility to reduce the encoding time by approximately 13.6%, while the scheme suffers from a negligible average PSNR loss (dB 0.0033). The application of the proposed approach can reduce significantly the encoding time instead of the traditional encoding in the H. 265/HEVC video codec and can be recommended for the further study by the JCT-VC (Joint Collaborative Team on video Coding).
