“…However, a lower shutter speed also increases motion blur, which is caused by the camera integration of an object position over time, while the shutter is opened. Thus, strobing artifacts and motion blur can not be optimized independently except by using a higher frame-rate [21].…”

“…For the purpose of the UHDTV signal definition, several studies further investigated the importance of HFR for television [9], [11], [25]. Emoto et al [25] showed that increasing the frame-rate from the traditional 60 fps to high frame-rate of 120 fps provides a significant visual quality improvement.…”

“…It is also stated that a further increase to 240 fps would also improve the motion portrayal but to a much lesser extent than the transition from 60 to 120 fps. Salmon et al [11] have also studied HFR for television, showing that at least 100 fps is required for improvements over HDTV, especially for content with high motion such as sports. Recently, with one of the first 65 inches UHD HFR prototype displays, Hulusic et al [9] studied the joint and independent contributions of 4K resolution and HFR.…”

“…Several papers [5]- [11] have investigated the HFR 1 video signal and shown its impact to enhance the viewing experience by reducing temporal artifacts specifically motion blur and temporal aliasing [5]. Authors in [9] have conducted subjective evaluations and shown that the combination of HFR (100 fps) and high resolution (4K) significantly increases the QoE when the video is coded at high bit-rate.…”

“…Moreover, this study shows that HFR improves the quality of video content with camera motion, while lower frame-rates are more convenient for sequences with complex motion such as dynamic textures. The study conducted in [11] by the British Broadcasting Corporation (BBC) showed that down-conversion of HFR video to 50 fps would inevitably result in considerable quality degradation. Mackin et al in [12] have presented a new database containing videos at different frame-rates from 15 fps to 120 fps.…”

The Digital Video Broadcasting (DVB) has proposed to introduce the Ultra-High Definition services in three phases: UHD-1 phase 1, UHD-1 phase 2 and UHD-2. The UHD-1 phase 2 specification includes several new features such as High Dynamic Range (HDR) and High Frame-Rate (HFR). It has been shown in several studies that HFR (+100 fps) enhances the perceptual quality and that this quality enhancement is contentdependent. On the other hand, HFR brings several challenges to the transmission chain including codec complexity increase and bit-rate overhead, which may delay or even prevent its deployment in the broadcast echo-system. In this paper, we propose a Variable Frame Rate (VFR) solution to determine the minimum (critical) frame-rate that preserves the perceived video quality of HFR video. The frame-rate determination is modeled as a 3-class classification problem which consists in dynamically and locally selecting one frame-rate among three: 30, 60 and 120 frames per second. Two random forests classifiers are trained with a ground truth carefully built by experts for this purpose. The subjective results conducted on ten HFR video contents, not included in the training set, clearly show the efficiency of the proposed solution enabling to locally determine the lowest possible frame-rate while preserving the quality of the HFR content. Moreover, our VFR solution enables significant bit-rate savings and complexity reductions at both encoder and decoder sides.

This paper describes a novel 4K 120 fps (frames per second) real-time HEVC (High Efficiency Video Coding) encoder for highframe-rate video encoding and transmission. Motion portrayal problems such as motion blur and jerkiness may occur in video scenes containing fast-moving objects or quick camera panning. A high-frame-rate solves such problems and provides a more immersive viewing experience that can express even the fast-moving scenes without discomfort. It can also be used in remote operation for scenes with high motion, such as VAR (Video Assistant Referee) systems in sports. Real-time encoding of high-frame-rate videos with low latency and temporal scalability is required for providing such high-frame-rate video services. The proposed encoder achieves full 4K/120 fps real-time encoding, which is twice the current 4K service frame rate of 60 fps, by multichip configuration with two encoder LSI. Exchange of reference picture data near a spatially divided slice boundary provides cross-chip motion estimation, and maintains the coding efficiency. The encoder supports temporal-scalable coding mode, in which it output stream with temporal scalability transmitted over one or two transmission paths. The encoder also supports the other mode, low-delay coding mode, in which it achieves 21.8 msec low-latency processing through motion vector restriction. Evaluation of the proposed encoder's multichip configuration shows that the BD-bitrate (the average rate of bitrate increase), compared to simple slice division without inter-chip transfer, is −2.86% at minimum and −2.41% on average in temporal-scalable coding mode. The proposed encoder system will open the door to the next generation of high-frame-rate UHDTV (ultra-high-definition television) services.
