Any preservation effort must begin with an assessment of what content to preserve, and web archiving is no different. There have historically been two answers to the question “what should we archive?” The Internet Archive's broad entire-web crawls have been supplemented by narrower domain-or topic-specific collections gathered by numerous libraries. We can characterize this as content selection and...
Organizations need to announce activities (e. g meetings), run polls, give information, gather feedback about their business and make advertisements. With the improvements in IVR technology, fixed & mobile phones create a great opportunity to meet those needs. Mass-IVR System was designed with those facts and necessities as motive and it provides the ability to call millions of telecom subscribers,...
With the continuous development of Internet technology, not only the number of Internet users is increasing, the contents of dissemination are abundant, but also communication forms change rapidly, such as micro-blog, micro message and so on. For science communication, Internet has become an effective scientific communication media, and plays a great role in communication. But at the same time, the...
Most of things would be connected into internet and it will be evolved into web of objects(WoO) which can share the information each of the thing-in-itself with the internet of things(IoT) service environment. The web of object in IoT objectifies and virtualizes things and it generates and provides new services with mashup of objectified things with context information. The thing in the web of object...
“Gatekeeping theory” is the conceptual framework that was developed during the 20th century within the journalism and mass communication research discipline to help us understand the complex, multivariate factors that collectively influence the content of the media. But gatekeeping theory in its extant form is limited in its descriptive value for today's media environment because it was developed...
In this paper, the convergence of Internet of Things (IoT) and 3GPP LTE-A network is discussed. With the cooperation of enormous smart devices, various kinds of information would be gathered and transmitted to the central control and processing entity, 3GPP LTE-A network provides the ideal access network for the IoT. Meanwhile, there exist several potential issues for the convergence of IoT and 3GPP...
In this contribution we discuss whether or not learner control may be considered as key-component in the development of distance education. We argue that different factors -for example: new technologies, the increased importance of some competencies, and ‘weisure’- may lead to the assumption that learner control is a prevalent condition to make distance education more effective. Moreover, there is...
Traditional media are now facing a great challenge from digital media, especially the Internet, so the survival and development of traditional media and the innovation of the traditional media's products, especially news products, in the digital age have become hot issues. Based on the theory of the gratification-utility niche, the relationships between traditional media and new media include “time...
This paper proposes a home gateway architecture which integrates P2P file sharing and UPnP AV services on the OSGi framework. This design allows UPnP devices to access P2P media content from the Internet. Prototype demonstration presents several friendly UPnP-style scenarios for P2P AV entertainment in a home network environment.
With the advancement of Internet technologies and the widespread use of mobile devices, the number of users in conferencing services is increasing quickly. A P2PSIP conferencing system and an IP Multimedia Subsystem (IMS) conferencing system have been designed to provide conferencing services. The IMS conferencing system was developed to adapt to a server-based centralized system, while the P2P network,...
This paper is a qualitative examination of the participatory potential of social media, focusing on a student-organized protest against censorship in Singapore. While the debate regarding the impact of new media on politics is well-documented, few studies have explicitly detailed the process of online civic mobilization in terms of its contribution to the more traditional forms of political participation,...
Delivering multimedia streaming on Internet remains several limitations, such as bandwidth fluctuations and network conjunction. We present a multimedia gateway design including dynamic bandwidth estimation, SVC extractor and buffer management to resolve the limitations. The dynamic bandwidth estimation not only selects the appropriate SVC sub-stream, but also measures the change of bandwidth and...
This paper presents a development use case of event-based system using (embedded) services specified in UPnP specification. Although we use only UPnP, we considered that the use case is also applicable for other (XML-based) service description technologies.
To solve the management problem of different vendor' appliances, the paper proposes a portable, low-cost, extendable and centralized control network of smart appliances(SA) and a embedded smart home gateway(ESHG), defined a protocol of SA(called IA_WRAPER) and user's operating primitive language. This structure and protocol shielded the different control modes and the different communication media...
DLNA devices, by definition, do not support remote connectivity. Even if attached to a LAN that is connected to the Internet, they can generally not be used to consume streamed or downloadable media. By providing a gateway in a mobile phone that exposes a 'remote Digital Media Server' on the LAN, content from different online sources can be made available on locally connected media renderers. Adding...
Supporting Quality of Service (QoS) in a core transport is an important feature of a next generation network. This feature not only enables real-time communication services such as Voice over IP (VoIP) and video telephony, but also helps create new applications. However, access gateway such as Packet Data Gateway (PDG) in IMS WLAN Interworking, located at the edge of an IMS core network, must inspect...
The purpose of this study is to review the characteristics of Web portal quality from the end-users' perspective and to propose a Web portal quality model. In this study, the quality of web portals consists of three basic components: the information content (e.g., accuracy and applicability), the physical medium (e.g., timeliness and speed), and the service (e.g., reliability and responsiveness of...
Voice-over-IP (VoIP) is a key component of next-generation-networks and rapidly becoming more and more common in the Internet in general. This also increases the demand of VoIP operators for a scalable, distributed and flexible monitoring. But current monitoring architectures are either not designed for including application layer protocol analysis and data acquisition, or they are very specific and...
Social communities are emerging as cloud-based service platforms for communities that also offer communication channels to their users. At the same time, modern telecommunications providers are currently seeking for new sources of revenue by exposing network capabilities to 3rd party providers. Moreover, both mobility and the possibility to access services anyhow, anywhere and at any time are becoming...
Intelligent home appliances and friendly human-machine interface design can provide a more comfortable living space for residents in smart home. However, excessive home automation sometimes may lose the sense of reality on operating home appliances. Virtual objects in smart home are not real home furnishings, and equipments, but it has the ability of actual home appliances or equipment to provide...
