In this paper, we propose a fast PU decision method to reduce encoder complexity. We use an early PU decision in each CU-level based on spatio-temporal analyses and depth correlations. We also consider a classification of motion activity. Experimental results show that the encoding complexity can be reduced by up to 37.98% on average in the random access(More)
High Efficiency Video Coding (HEVC) has brought significant improvement to video compression in terms of coding performance and subjective quality. However, it is computationally more complex than H.264/AVC, and hence adaptation of HEVC to real-time video services has not been promising. In order to reduce the computational cost, we propose a fast mode(More)
After the success of H.264/AVC, a next generation codec for Ultra-HD resolution video is being developed under the name called High Efficiency Video Coding(HEVC). This paper presents an optimization method for HEVC by performing early termination that preventing further CU split. In our experiments, the early termination method reduces the computational(More)
This paper presents an efficient audio/video synchronization method that is quite suitable for video telephony. In terms of computational complexity and simplicity of the software structure, the proposed algorithm shows improved results compared to the conventional synchronization algorithm. The derived audio/video synchronization algorithm is compactly(More)
High efficiency video coding (HEVC) is the newest video coding standard that can support powerful video compression performance with increased picture resolution for ultrahigh definition (UHD). Compared to the previous standard, HEVC achieved a coding efficiency double with a tremendous increase in encoder computational complexity, making support of(More)
