Internet of Vehicles (IoV), which plays a significantly important role in smart future cities, has become current hot research topics. However, the high heterogeneous nature IoV brought many new challenges such as low network performance and difficult management for IoV. Software-defined networking enables efficient solution these problem. This article studies measurement analysis technology software-defined A networking-based framework is proposed to build We propose method measure...
While virtual reality (VR) videos have attracted significant amount of attention and efforts, the development VR is still quite challenging. Among challenges, need for enormous bandwidth in live streaming hasn't yet been addressed satisfactorily. To tackle this aspect, we propose a 360° system based on MPEG media transport (MMT) to guarantee delivery video as well user experience. Within proposed scheme, divide integrated into multiple partitioned videos, encode encapsulate different MMT...
Instead of streaming the entire OmniDirectional Videos (ODVs) that are often sampled at ultra high definition and frame rate, a viewport adaptive is preferred in practice. We usually stream High-Quality (HQ) content within current viewport, while Low-Quality (LQ) elsewhere to save network bandwidth consumption. Such scheme would lead quality refinement after user adapts his/her focus new viewport. In this paper, we thus model perceptual impact variations (through adjusting Quantization...
Immersive video offers the freedom to navigate inside virtualized environment. Instead of streaming entire bulky content, a viewport or field view (FoV) adaptive is preferred. We often stream high-quality content within current viewport, but degraded-quality representation elsewhere, so as reduce network bandwidth consumption. then could refine quality when focusing new FoV. Therefore, in this work, we have attempted model perceptual response variations (through adapting quantization and...
Steroid 11β-hydroxylase deficiency (11β-OHD) is a rare autosomal recessive disorder caused by pathogenic variants of CYP11B1 gene. This study aimed to perform molecular analysis Chinese 11β-OHD series and in vitro functional twenty missense variants. Twelve patients with clinical diagnosis were included the analyze their etiology. Genomic DNA was extracted be sequenced all coding exons intronic flanking sequences CYP11B1. Fourteen found 12 mentioned above along 6 previously reported our team...
Immersive video offers the freedom to navigate inside virtualized environment. Instead of streaming bulky immersive videos entirely, a viewport (also referred as field view, FoV) adaptive is preferred. We often stream high-quality content within current viewport, while reducing quality representation elsewhere save network bandwidth consumption. Consider that we could refine when focusing on new FoV, in this paper, model perceptual impact variations (through adapting quantization stepsize...
Viewport-Dependent Streaming (VDS) is a preferred way in practice to deliver the omnidirectional videos, of which High-Quality (HQ) scale applied for content current viewport but Low-Quality (LQ) elsewhere. Quality adaptation or refinement happens after users stabilize their fixations new viewport. In this article, we formulate as perceptually optimized quality problem maximize Experience (QoE) from LQ another HQ level within specific duration under given network constraint. With our...
For transmitting bulky virtual reality (VR) videos efficiently, one industry-recognized mechanism is partitioning each of them into tiles and streaming the corresponding content according to user's viewport (field view, FoV). The performance FoV-based management can be improved by FoV prediction that are prefetched stored in buffer. Buffer great concern guarantee consecutive smooth playback throughout whole navigation. In this paper, we design a novel VR video system using MPEG Media...
For realizing finer granularity rate adaptation with tradeoff between visual quality and network bandwidth, DASH provides sub-representation structure that can further refine QoE options multiple temporal operating point at a fixed spatial quality, i.e., PSNR. In order to facilitate streaming driven decisions sub-representations, in this paper, we shall develop new for constructing sub-representations. Besides, utilize the fame significance metric characterize introduce gradient layer...
Immersive video applications grow faster for users to freely navigate within a virtualized 3D environment entertainment, productivity, training, etc. Fundamentally, such system can be facilitated by an interactive Gigapixel Video Streaming (iGVS) platform from array camera capturing end user interaction. This demands large amount of network bandwidth sustain the reliable service provisioning, hindering its massive market adoption. Thus, we propose segment gigapixel scene into non-overlapped...
Owing to the characteristics of exquisite and efficient presentation, 3D point cloud has attracted significant attentions. Given that dynamic consists geometry texture information, they often possess different importance on visual quality. In this paper, we propose a rate allocation scheme for Unequal Error Protection (UEP) in cloud. The proposed algorithm is based Video-based Point Cloud Compression (V-PCC) standard, which processes into 2D frame sequences. We allocate code according...
