A dynamic media access control protocol named DAND-MAC(Directional Antenna Neighbor Discovery and Media Access Control) is presented, which is designed to operate in the link layer of Mobile Ad-hoc Networks(MANETs) based on directional antenna. Omnidirectional antenna and directional antenna can operate synchronously with the unified scheduling of this protocol.Omnidirectional antenna takes the charge of topology and neighbor discovery, while directional antenna processes to build the link and the transmit data. This paper describes the system structure, key techniques of DAND-MAC. The simulations are operated with OPNET Modeler. The simulation results show that the performance of DAND-MAC could increase significantly in end-to-end delay, throughput and the reusability of time slots, comparing with traditional static time slot allocation and dynamic time slot allocation based on omnidirectional antenna. © 2017, Editorial Department of Journal of Beijing Jiaotong University.

This paper presents a novel intra prediction algorithm, named position-dependent filtering (PDF), to improve the intra prediction accuracy. Different from the existing schemes where the samples along one prediction direction are predicted with the same set of filtering coefficients, in the proposed PDF, position-dependent filtering coefficients are employed, i.e., different sets of filtering coefficients are pre-defined for samples with different coordinates in one coding block. For each intra prediction mode, the set of linear filtering coefficients for each position within one block is obtained from off-line training using the least square method. Moreover, to further reduce the algorithm complexity, a simplified PDF (sPDF) is proposed. In sPDF, only a subset of reference samples are used for prediction and the others are discarded because of the minor contribution to intra prediction. The proposed algorithm has been implemented in the latest ITU-T VCEG KTA software. Experimental results demonstrate that, compared with the original KTA with new intra coding tool enabled, up to 0.53 dB of average coding gain is achieved by the proposed method, while applicable computational complexity is retained for practical video codecs. © 2010 Elsevier Inc.

Natural phenomena simulation is an important research area in computer graphics domain. How to obtain realistic natural phenomena by simulation in an efficient way is the main purpose of this research field. The physics-based modeling method is a traditional way to solve this kind of problem. Along with rapid development of acquisition devices, the image-based method attracts a lot of research attention and interest. This paper chooses liquid as research object. Main research achievements on the topic of image-based reconstruction are summarized. Focusing on dynamic water surface, a method of dynamic water surface data acquisition and reconstruction is proposed. First, a dynamic water surface data acquisition system is designed and built in order to obtain image sequences of different water surface phenomenon on multi-viewpoint. Next, feature points on each captured images in sequences are extracted. Then after feature point matching process, the mapping relationship between feature points and 3D points are built. Finally, dynamic water surface reconstruction results are obtained by using the height field and normal of 3D point combined with the optical refractive property of water. Experimental results show that this method can generate 3D reconstruction results rapidly. Satisfactory visual effect is also achieved facilitating this application to be used in computer games, visualization in scientific computing, and virtual simulation in medical area. © Copyright 2016, Institute of Software, the Chinese Academy of Sciences.

The second generation of Audio and Video coding Standard (AVS) is developed by the IEEE 1857Working Group under project 1857.4 and was standardized in 2016 by the AVSWorking Group of China as the new broadcasting standard AVS2. High Efficient Video Coding (HEVC) is the newest global video coding standard announced in 2013. More and more codings are migrating from H.264/AVC to HEVC because of its higher compression performance. In this paper, we propose an efficient HEVC to AVS2 transcoding algorithm, which applies a multi-stage decoding information utilization framework to maximize the usage of the decoding information in the transcoding process. The proposed algorithm achieves 11×-17× speed gains over the AVS2 reference software RD 14.0 with a modest BD-rate loss of 9.6%-16.6%. © 2016 by the authors.

BEIJING, Nov 22, 2016 /PRNewswire/ -- As the 2016 China-U.S. Tourism Year draws to an end, Yale University and American University held the "VR Experience Day of Beautiful China" event, a VR promotion program similar to Google's Expeditions VR program which hit the campus last year, but this time, from China. As the organizer of this event and one of the first organizations that developed VR content, China Intercontinental Communication Center (CICC) brought hundreds of VR tourism scenes in China to the U.S. This event presented the students with famous mountains and rivers, as well as scenic spots in China, including Fujian, Guilin, and Mount Huangshan. Thousands of pieces of VR equipment were available for the students, and those who participated gave great feedback, expressing their wishes to go to China to see the beautiful and magical scenes in person. Rose Ann Robertson, interim Senior Associate Dean of the School of Communication of American University, told CICC that as a form of media, VR shortens the distance between different parts of the world, and allows people to know more about each other. She also expressed that she hoped to have more cultural exchanges with China and would like to take her team to China for a visit. College students from both China and the U.S. showed great enthusiasm for VR technology. Students from Beijing Film Academy and one of the prize-winners of the first "Meeting China" VR Youth Photography Exhibition, were also present, and shared his experience in VR content production with U.S. students. CICC encouraged young Americans to participate in the second "Meeting China" VR Youth Photography Exhibition, inviting them to come to China in 2017 and see a beautiful China through VR technology. According to a report, many Chinese institutions and individuals have been exploring VR technology since 2014 leading to almost synchronous development in hardware equipment and content development with the rest of the world. As a known international cultural exchange organization, CICC is the largest VR content producer in China, and has gained attention and support for non-game, non-entertainment industrial applications from organizations and companies, including AMD, Dell and related organizations.

The video service is one of the most important Internet services, and user quality of experience (QoE) represents the degree of recognition of the video service. Therefore, research on QoE is significant in improving the quality of the video service. Considering the influence of different factors on QoE, this paper studies the effect of video content types on QoE. In this article, we divide videos into seven types: entertainment, cartoon, sport, news, music, teleplay, specialty. Besides, we utilize user engagement to measure QoE. The study shows that the correlation which is mainly reflected in following aspects between video types and QoE is substantial. Firstly, video types can impact QoE directly. For example, the proportion of high engagement of cartoon is higher than other videos by 30%. Secondly, video types affect the distribution of the key performance indicators (KPIs). Lastly, video types influence the correlation between user engagement and KPI. © 2015 IEEE.

Clustering algorithms are some of the most important algorithms used to describe data attributes and very effective ways to mine and analyze big data set. In this paper, the whole description of vector space of Internet users is acquired by clustering and analyzing user behavior data set. Moreover, all users are divided into different clusters according to KPI which is to correlate different users in terms of their degree of video completion. Our research shows that KPI of total length correlates degree of completion better than other KPIs. This KPI is drastically negatively correlated with user degree of video completion. Finally, we compare the accuracy and efficiency of three different algorithms which we used to cluster our research data in this paper. © 2015 IEEE.

With the rapid development of Internet video service and the continuous expansion of user scale, to dig out the user behavior patterns accurately from the user data and obtain some valuable regularities of the user behavior can help the Internet video operators to improve service quality and enhance the user's quality of experience (QoE), so that achieves the purpose of improving economic benefits. The goal of this paper is to provide a better understanding of the user behavior for video operators. To this end, we research the user behavior in the scene of large scale Internet video service based on the data set captured from one of the largest operators of China. By the way of statistical analysis and data mining of large scale user data, we conclude several regularities and statistical models of the user behavior. We also develop a deep study on the relevant factors that impact the user behavior, and focus on the relevance between the user behavior and video length, video popularity, buffer rate, error rate, which find out that the buffer rate have a significant impact on the user behavior, while the video popularity have a weak correlation with the user behavior. © 2015 IEEE.
