Adaptive content streaming is frequently used as an efficient and cheap solution to achieve a good quality for media streaming, in systems having light Over-the-Top architectures. The streaming system developed here makes an initial optimized server selection based on multi-criteria algorithms and then in-session media adaptation. The focus of this paper is on performance analysis (based on real-life...
Peak loads are a challenge for streaming systems. Here we present Dslash, a latency-driven controller that keeps and processes as much data as the system resources allow in order to meet a target latency.
Broadcasting corporations have begun distributing programs via Internet simulcast and video on demand (VOD). Such diversification of content distribution has created various ways for users to view programs, e.g., broadcast on TV, Internet simulcast on smartphones, and VOD on a connected TV. However, at the same time, this diversification of viewing operations creates complexity that can hamper users'...
Customized presentation is gaining more popularity. The MPEG media transport (MMT) system provides flexible media unit encapsulation and comprehensive control signaling to support multiple content types that may be useful during the customization. Existing legacy methods, however, did not take into account relations within media asset and the combination of diverse media components. Furthermore, considering...
In this paper we present a personalized video composition method based on user intention learning. The proposed system generates video clips by choosing user's assets such as still images and video clips based on pre-designed templates. The search-and-suggestion technique plays an important role for providing appropriate templates. We mainly focus on the learning mechanism which will be gradually...
In this paper, we present a dynamic framework for P2P video streaming using dynamic adaptive streaming over HTTP (DASH). DASH is a very popular standard and is expected to dominate the adaptive streaming market. Our proposed framework defines several components; DASH Session Coordinator (DSC), Intelligent Content Server (ICS), and Adaptive Streaming Client (ASC). Each component has a defined set of...
This paper proposed a smart home care system for elderly or baby on mobile devices. The system can help users to use their smartphones to quickly build a smart monitor network at home anytime and anywhere. The system is based on live video streaming and image processing techniques. Based on video streaming, we can watch the elderly or baby anytime and anywhere. In addition, we combined object tracking...
Remote collaboration systems are a necessity for geographically dispersed teams in achieving a common goal. Real-time groupware systems frequently provide a shared workspace where users interact with shared artifacts. However, a shared workspace is often not enough for maintaining the awareness of other users. Video conferencing can create a visual context simplifying the user's communication and...
Content delivery networks deliver much of the world's web and video content by deploying a large distributed network of servers. We model and analyze a simple paradigm for client-side server selection that is commonly used in practice where each user independently measures the performance of a set of candidate servers and selects the one that performs the best. For web (resp. video) delivery, we propose...
There exist two classical and well-understood approaches to video processing tasks (such as mixing or trans-coding) for videoconferencing. The first one is using a centralized Multipoint Control Unit (MCU), hardware or software based, deployed on-premises or in the cloud. In the second approach, the video processing tasks are directly handled in endpoints (i.e. equipment such as PCs, laptops, tablets...
Multimedia streaming between smart devices has come into general use in Wi-Fi networks, for example, streaming a video content in mobile phone to smart TV. However, drastic and frequent changes of link quality caused by wireless channel characteristics such as multipath fading and Doppler effect leads the network throughput unstable. In order to support seamless play even in unstable wireless link,...
Many Software-Defined Networking (SDN) controllers support a “northbound interface” by which applications can interact with the SDN controller and (indirectly) control the underlying SDN network. The absence of a standard for the northbound interface of these controllers makes it difficult for application developers to create interoperable/portable code (i.e., code that works with any SDN controller)...
This paper proposes ''SmileWave", a system for revealing smile-based emotional contagion, propagation effect of the similar emotion through smiley facial expression, on the social network where users interact each other through web-based user interface rather than in-person interaction. SmileWave is a picture-based networking service and detects the change of smile degree when the user looks...
Multimedia streaming between smart devices has come into general use in Wi-Fi networks, for example, streaming a video content in mobile phone to smart TV. However, drastic and frequent changes of link quality caused by wireless channel characteristics such as multipath fading and doppler effect leads the network throughput unstable. In order to support seamless play even in unstable wireless link,...
WebRTC-based applications are assumed to be based mostly on peer-to-peer communication, where an instance of the application is talking to another instance. However, this is not always the case: a WebRTC-based application communicating with a legacy VoIP device or Media Server like a Video Conference Server is also very common. The ability to make both types of communications (WebRTC to WebRTC and...
Most Content Delivery Networks (CDNs) are operated as a Software as a Service (SaaS): Many cloud providers build their custom CDNs to benefit from content users, as well as reduce demand on their own telecommunications infrastructure. More importantly, though, CDNs contribute to cloud adoption, as they can address network problems of cloud computing. With multimedia content providers requiring CDN...
Media Streaming is a multimedia that is sent over a network and played as it is being received by the end users. With large volumes of multimedia data in P2P systems, locating data needs to address a multi-modal retrieval. There are a lot of challenges in achieving QoS in P2P systems such as churn in the systems, free riding problems, bottlenecks etc. In this paper, to achieve high QoS for live media...
Most businesses collect and store sensitive information about their work or related like project documents, audio data, video data etc. while sharing files in peer-to-peer system dynamically peer nodes can add may delete. Peer-to-Peer file sharing using P2P application architecture. Shared files will move between different nodes. P2P technology is using by popular services like Napster, Bit Torrent,...
The goal of this project is to use projection augmented reality to add design studio learning models to a classroom for an introductory Media Computation computer science class. Students do classwork using an enhanced version of Pythy, a web IDE for Python and Jython, that captures students' work and displays it around the room. We leverage the Microsoft RoomAlive Toolkit to construct a room-scale...
In this research, we propose a Common Infrastructure System for the disaster countermeasures headquarters to transmit disaster information to residents speedily at the time of large-scale natural disaster. A Common Infrastructure System realizes digitization of the disaster information concentrated in the disaster countermeasures headquarters. And, this system extracts only the information, which...
