英文摘要
HEVC is a new video coding technique, the standard developed by JCT-VC (Joint Collaborative Team on Video Coding), that is able to support ultra high definition video coding. In HEVC, there are three types of encoding block: Coding Unit (CU), Predict Unit (PU) and Transform Unit (TU). If every block of video pixels goes through the complete mode decision process, a lot of encoding time is required, limiting its applicability in real-time applications. This paper proposes a fast algorithm that can improve the computation time of intra coding for each coding unit (CU) block. In the proposed algorithm, the depth information of coding block tree (CBT) from the previously encoded frame is used to help determine the current CU split depth and can skip many unnecessary mode computation for some cases of block decomposition. Experimental results by HM10.1 show that the proposed method can provide about 16% of time saves and maintain an acceptable video quality.
