“…Huang et al [11] efficiently switch AMP by posterior probability analysis and adaptively adjust the search range by motion degree. Huang et al [12] predict the CU depth range from neighboring CTUs. In addition, the coding information of Merge/Skip 2N×2N and CBF is utilized for the decisions of early split and early termination.…”

High Efficiency Video Coding (HEVC/H.265) is the latest international video coding standard, which achieves better compression ratio and supports higher resolution than Advanced Video Coding (H.264/AVC). However, HEVC/H.265 increases the computational burden. To reduce the coding complexity of the HEVC encoder, this paper proposes a fast inter-prediction algorithm to speed up coding time. We collect the average rate-distortion costs (RD-cost) of Skip modes and Merge modes to accelerate prediction unit (PU) mode decisions. In addition, we also acquire and analyze the motion vector range from Merge modes and Inter 2N × 2N modes to decide whether to execute Merge and advanced motion vector prediction (AMVP) of other PUs. The experimental results show that the proposed algorithm provides 48.54% time saving on average in random-access configuration and maintains good rate-distortion performance and video quality at the same time. The proposed algorithm also outperforms previous works.

“…M u et al [12] proposed a fast CU depth decision method by exploiting the relationship between the rate distortion cost and CU depth. H u a n g et al [13] proposed an adaptive depth search range for HEVC coding unit size selection according to the coded block flag and the information of the quantization parameter. However, these methods cannot efficiently remove the complexity of H.265/HEVC encoder of a videoconferencing system due to the fact that video content properties are not considered by these methods ( Fig.…”

With the development of Internet and video capture techniques, videoconferencing becomes still more popular. However, with the increased size of the video resolution, the volume of the raw videoconferencing video data increases dramatically. The H.265/HEVC video compression standard can efficiently compresses the videoconferencing video, while the high compression rate is at the cost of heavy encoding complexity. Hence, reducing the complexity is vital to be used for the H.265/HEVC encoder in videoconferencing systems. In this paper we proposed a low complexity H.265/HEVC coding unit size decision algorithm for a videoconferencing system, by considering the coding content property of the coding unit, in which the coding unit size decision process is terminated if the prediction residuals of the coding unit are all transformed and quantized to zeroes. The experimental results show that the proposed algorithm achieves 62.79% on average in encoding time saving, while the rate distortion degradation is acceptable.
