User-Centric work Space (UCS) service enables a personalized (user-centric) work space for a user by orchestrating local and/or remote IT resources. Instances of IT resources include file, printer, monitor, keyboards. With UCS service, a user can have his personalized and secure work environment at anywhere and anytime by storing and processing his data in secure manner without any interference from...
We propose distributed media computing method for high performance and massive computing of media processing. By dividing media streams temporally and spatially, and processing them, the method reduces the elapsed time of media processing and improves the system scalability. The experiment results show the method increases the elapsed time. The performance degradation could be mitigated using high-speed...
The benefits of transcoding make it possible an incompatible or obsolete contents to be run at any device in a modern format. Nowadays, it is a common way to transcode contents to another format, different bitrates or qualities. As there are some limitations on the source computer which is like thin client with very low H/W specification, it is preferably recommended to be processed on the cloud environment...
The use of recording applications for teaching is increasingly popular, with tools such as Ink2Go and ShowMe being available on many platforms and at reasonable cost. However, most recording applications available are typically native applications and do not work within the web browser. In this work, we study the feasibility of implementing a recording solution in the web browser environment.
Adaptive HTTP Streaming has become a widespread technology for delivering video to the end users. However, this technology usually suffers from various latencies, requiring an initial delay before playback. This is problematic for low delay or interactive applications, such as gaming or live event webcasting. A long initial waiting time is perceived by most users as bad quality, or even non-working...
This paper describes two mobile learning journeys in the zoo using either smartphones or tablets, and a mobile learning application SamEx, all designed and implemented as part of a research study in a Singapore primary school. Out-of-school semi-formal learning activities such as zoo trips present standard curricular topics where students go out of their schools in order to explore topics of interest...
Accessing the latest information of scientific and technological research projects and its results, is an essential requirement for the success in innovation. To provide the information access, Information Management Models are needed to promote innovation and improvement of existing research.
WebRTC is an HTML5 API that allows browsers to establish a peer-to-peer connection for transferring data and media content via JavaScript APIs. This functionality enables broad range of new applications to emerge and is going to revolutionize Web communication. However, this technology is still under development and standardization process. Hence, detecting performance bottlenecks of different implementations...
The increasing popularity of photo sharing in social networking service (SNS) complicates the challenge of storing and transmitting large photo data for SNS providers. Distributed web caches are generally used by SNS providers to improve data transmission performance effectively. Two critical factors affect the efficiency of web caches: storage media and replacement algorithms. Solid-state drive (SSD)...
Dynamic Adaptive Streaming over HTTP (DASH) standard was designed to improve quality of experience (QoE) by enabling video distribution at different quality levels according to the clients' network conditions. Moreover, DASH is compatible with the H.264 Scalable Video Coding (SVC) technology. In Content Delivery Networks (CDNs)-P2P hybrid approach, users can fetch contents from the CDN edge network,...
HTTP ABR Video Streaming based methods are being used by certain media players and video servers. With this, video is encoded with different data rates, stored on a content server (if possible) and streamed to different client devices. Media player at client device considers various performance factors and decides the rate that it should ask for the next video segment. There are different types of...
A social media message that is forwarded (e.g., Retweeted in Twitter) by many users may diffuse widely. Such a 'viral' message may have a major impact in the real world. If the content maligns a company, the company must respond as quickly as possible to defend its brand image. Timely knowledge about what kinds of information are diffusing in social media is thus quite important. We have developed...
Two communication media between meter and server are applicable in Electrical Distribution Company (EDCO) in Jordan), namely, the Power Line Carrier (PLC) and the General Packet Radio Service (GPRS). In this paper, we discuss the implementation of these two communication media in the Automated Meter Reading (AMR) and the Advanced Metering Infrastructure (AMI) project in Jordan; and also point-out...
Twitter is one of the many social media accessible to users in Indonesia. The official account in one of these organizations is very dangerous if the official account is used by many users that do tweet and the data is not store who, what time doing it. Moreover, if the official account is already too much to millions. This paper propose a framework can work on recording data i.e. who, what time all...
The rapid growth of the Internet users brings on bandwidth bottleneck. Consequently, it is difficult to guarantee the video service quality of the online streaming media platform. This paper mainly introduces the current situation of streaming media platform, analyzes the network performance and the existing problems, and then puts forward the corresponding research scheme. It specifically adopts...
Traditional observational research methods required an experimenter's presence in order to record videos of participants, and limited the scalability of data collection to typically less than a few hundred people in a single location. In order to make a significant leap forward in affective expression data collection and the insights based on it, our work has created and validated a novel framework...
Omni Media has become an important trend with the development of information services in the context of network convergence and screen integration. In such an environment, Internet interaction is no longer limited to the computer, users can also access Internet resources through wearable and other smart computing devices. This paper proposes a multimedia repository system, which is composed of client...
Interactive digital displays are now finding their way in various public spaces as tools for information dissemination. Current methods of deploying such technologies include installation of large screens along with expensive and bulky dedicated machines making them costly for multiple deployments. Interaction with these displays is done through sensors or through mobile applications but often fail...
Capturing, uploading, and presenting social media content online have become the standard way for people to share their experiences with friends, family members, and others. In this paper, we describe our effort to extract, aggregate, and visualize, in a smartphone app, real-time and historical hyperlocal social media discussions and photos created at a regional arts festival that attracted over 100,000...
Transfer data in only one network segment is not a sticky work. However, communication between different network segments is worth studying. Especially when one or both sides network segment behind NAT devices. This text has a brief description about the classification of NAT, and explains the problems that need to be solved about NAT traversal. According to the features of NAT and the needs of our...
