  • Delay-Sensitive Video Computing in the Cloud: A Survey
    • Abstract: Maha Abdallah, Carsten Griwodz, Kuan-Ta Chen, Gwendal Simon, Pin-Chun Wang, Cheng-Hsin Hsu

      While cloud servers provide a tremendous amount of resources for networked video applications, most successful stories of cloud-assisted video applications are presentational video services, such as YouTube and NetFlix. This article surveys the recent advances on delay-sensitive video computations in the cloud, which are crucial to cloud-assisted conversational video services, such as cloud gaming, Virtual Reality (VR), Augmented Reality (AR), and telepresence. Supporting conversational video services with cloud resources is challenging because most cloud servers are far away from the end users while these services incur the following stringent requirements: high bandwidth, short delay, and high heterogeneity. In this article, we cover the literature with a top-down approach: from applications and experience, to architecture and management, and to optimization in and outside of the cloud.

  • Cost-Efficient Server Provisioning for Cloud Gaming
    • Abstract: Yusen Li, Yunhua Deng, Xueyan Tang, Wentong Cai, Xiaoguang Liu, Gang Wang

      Cloud gaming has gained significant popularity recently due to many important benefits such as removal of device constraints, instant-on, and cross-platform. The properties of intensive resource demands and dynamic workloads make cloud gaming appropriate to be supported by an elastic cloud platform. Facing a large user population, a fundamental problem is how to provide satisfactory cloud gaming service at modest cost. We observe that the software storage cost could be substantial compared to the server running cost in cloud gaming using elastic cloud resources. Therefore, in this article, we address the server provisioning problem for cloud gaming to optimize both the server running cost and the software storage cost.

  • Game Categorization for Deriving QoE-Driven Video Encoding Configuration
           Strategies for Cloud Gaming
    • Abstract: Ivan Slivar, Mirko Suznjevic, Lea Skorin-Kapov

      Cloud gaming has been recognized as a promising shift in the online game industry, with the aim of implementing the “on demand” service concept that has achieved market success in other areas of digital entertainment such as movies and TV shows. The concepts of cloud computing are leveraged to render the game scene as a video stream that is then delivered to players in real-time. The main advantage of this approach is the capability of delivering high-quality graphics games to any type of end user device; however, at the cost of high bandwidth consumption and strict latency requirements. A key challenge faced by cloud game providers lies in configuring the video encoding parameters so as to maximize player Quality of Experience (QoE) while meeting bandwidth availability constraints.

  • Game Input with Delay—Moving Target Selection with a Game
           Controller Thumbstick
    • Abstract: Mark Claypool

      Hosting interactive video-based services, such as computer games, in the Cloud poses particular challenges given user sensitivity to delay. A better understanding of the impact of delay on player-game interactions can help design cloud systems and games that accommodate delays inherent in cloud systems. Previous top-down studies of delay using full-featured games have helped understand the impact of delay, but often do not generalize or lend themselves to analytic modeling. Bottom-up studies isolating user input and delay can better generalize and be used in models, but have yet to be applied to cloud-hosted computer games. In order to better understand delay impact in cloud-hosted computer games, we conduct a large bottom-up user study centered on a fundamental game interaction—selecting a moving target with user input impeded by delay.

  • ASAP: Adaptive Stall-Aware Pacing for Improved DASH Video Experience in
           Cellular Networks
    • Abstract: Ahmed H. Zahran, Jason J. Quinlan, K. K. Ramakrishnan, Cormac J. Sreenan

      The dramatic growth of video traffic represents a practical challenge for cellular network operators in providing a consistent streaming Quality of Experience (QoE) to their users. Satisfying this objective has so-far proved elusive, due to the inherent characteristics of wireless networks and varying channel conditions as well as variability in the video bitrate that can degrade streaming performance. In this article, we propose stall-aware pacing as a novel MPEG DASH video traffic management solution that reduces playback stalls and seeks to maintain a consistent QoE for cellular users, even those with diverse channel conditions. These goals are achieved by leveraging both network and client state information to optimize the pacing of individual video flows.

  • Designing and Evaluating a Mesh Simplification Algorithm for Virtual
           Reality
    • Abstract: Kanchan Bahirat, Chengyuan Lai, Ryan P. Mcmahan, Balakrishnan Prabhakaran

      With the increasing accessibility of the mobile head-mounted displays (HMDs), mobile virtual reality (VR) systems are finding applications in various areas. However, mobile HMDs are highly constrained with limited graphics processing units (GPUs) and low processing power and onboard memory. Hence, VR developers must be cognizant of the number of polygons contained within their virtual environments to avoid rendering at low frame rates and inducing simulator sickness. The most robust and rapid approach to keeping the overall number of polygons low is to use mesh simplification algorithms to create low-poly versions of pre-existing, high-poly models. Unfortunately, most existing mesh simplification algorithms cannot adequately handle meshes with lots of boundaries or nonmanifold meshes, which are common attributes of many 3D models.

  • User Behavior Analysis and Video Popularity Prediction on a Large-Scale
           VoD System
    • Abstract: Lei Huang, Bowen Ding, Aining Wang, Yuedong Xu, Yipeng Zhou, Xiang Li

      Understanding streaming user behavior is crucial to the design of large-scale Video-on-Demand (VoD) systems. In this article, we begin with the measurement of individual viewing behavior from two aspects: the temporal characteristics and user interest. We observe that active users spend more hours on each active day, and their daily request time distribution is more scattered than that of the less active users, while the inter-view time distribution differs negligibly between two groups. The common interest in popular videos and the latest uploaded videos is observed in both groups. We then investigate the predictability of video popularity as a collective user behavior through early views.

  • Novel Hybrid-Cast Approach to Reduce Bandwidth and Latency for Cloud-Based
           Virtual Space
    • Abstract: Xueshi Hou, Yao Lu, Sujit Dey

      In this article, we explore the possibility of enabling cloud-based virtual space applications for better computational scalability and easy access from any end device, including future lightweight wireless head-mounted displays. In particular, we investigate virtual space applications such as virtual classroom and virtual gallery, in which the scenes and activities are rendered in the cloud, with multiple views captured and streamed to each end device. A key challenge is the high bandwidth requirement to stream all the user views, leading to high operational cost and potential large delay in a bandwidth-restricted wireless network. We propose a novel hybrid-cast approach to save bandwidth in a multi-user streaming scenario.

  • Cloud Baking: Collaborative Scene Illumination for Dynamic Web3D Scenes
    • Abstract: Chang Liu, Wei Tsang Ooi, Jinyuan Jia, Lei Zhao

      We propose Cloud Baking, a collaborative rendering architecture for dynamic Web3D scenes. In our architecture, the cloud renderer renders the scene with the global illumination (GI) information in a GI map; the web-based client renderer renders the scene with ambient lighting only and blends it with the GI map received from the cloud for the final scene. This approach allows the users to interact with the web scene and change the scene dynamically through the web interface end, yet move the computationally heavy tasks of global illumination computation to the cloud. A challenge we face is the interaction delay that causes the frames rendered on the cloud and the client to go out of sync.

  • On the Effectiveness of Offset Projections for 360-Degree Video Streaming
    • Abstract: Chao Zhou, Zhenhua Li, Joe Osgood, Yao Liu

      A new generation of video streaming technology, 360-degree video, promises greater immersiveness than standard video streams. This level of immersiveness is similar to that produced by virtual reality devices—users can control the field of view using head movements rather than needing to manipulate external devices. Although 360-degree video could revolutionize the streaming experience, its large-scale adoption is hindered by a number of factors: 360-degree video streams have larger bandwidth requirements and require faster responsiveness to user inputs, and users may be more sensitive to lower quality streams. In this article, we review standard approaches toward 360-degree video encoding and compare these to families of approaches that distort the spherical surface to allow oriented concentrations of the 360-degree view.

  • Enabling Live Video Analytics with a Scalable and Privacy-Aware Framework
    • Abstract: Junjue Wang, Brandon Amos, Anupam Das, Padmanabhan Pillai, Norman Sadeh, Mahadev Satyanarayanan

      We show how to build the components of a privacy-aware, live video analytics ecosystem from the bottom up, starting with OpenFace, our new open-source face recognition system that approaches state-of-the-art accuracy. Integrating OpenFace with interframe tracking, we build RTFace, a mechanism for denaturing video streams that selectively blurs faces according to specified policies at full frame rates. This enables privacy management for live video analytics while providing a secure approach for handling retrospective policy exceptions.

  • Prototyping a Web-Scale Multimedia Retrieval Service Using Spark
    • Abstract: Gylfi Þór Guđmundsson, Björn Þór Jónsson, Laurent Amsaleg, Michael J. Franklin

      The world has experienced phenomenal growth in data production and storage in recent years, much of which has taken the form of media files. At the same time, computing power has become abundant with multi-core machines, grids, and clouds. Yet it remains a challenge to harness the available power and move toward gracefully searching and retrieving from web-scale media collections. Several researchers have experimented with using automatically distributed computing frameworks, notably Hadoop and Spark, for processing multimedia material, but mostly using small collections on small computing clusters. In this article, we describe a prototype of a (near) web-scale throughput-oriented MM retrieval service using the Spark framework running on the AWS cloud service.
