Digital Video Terrestrial Broadcasting (DVB-T) allows combining broadcasting, telephone and data services in one network. It has facilitated mobile TV broadcasting. Mobile TV broadcasting is dominated by fragmentation of standards in use in different continents. In Asia T-DMB and ISDB-T are used while Europe uses mainly DVB-H and in USA it is MediaFLO. Issues of royalty for developers of these ...

The development of adaptive learning systems is only in the very beginning. In fact, the concept of adaptive learning systems range from different user interfaces to behaviour adaptive systems as well as from the place and time independent systems to terminal independent systems. When approaching the concept of adaptive learning materials, we must first have conceptual models of the behaviour o...

The market for portable devices is stimulating the migration of technologies originally developed for PCs to the realm of handhelds and wireless networks. Agent technology is following this downsizing trend, and many projects are under way to enable multiagent systems on handheld devices. The possibility of enabling agent technology in the telecommunications world, with its base of several hund...

In this paper, we present a computation offloading scheme on handheld devices. This scheme partitions an ordinary program into a client–server distributed program, such that the client code runs on the handheld device and the server code runs on the server. Our partition analysis and program transformation guarantee correct distributed execution under all possible execution contexts. We give a ...

This paper presents an experimental wireless Classroom Communication System (CCS) used for continuous and interactive engagement of students aiming at enhancing student critical thinking, extending attention span and enabling better student assessment. . The paper describes the main infrastructure upon which this CCS structure is based as well as some of its most important features. The system ...

The current proliferation and ubiquity of electronic applications and services has motivated the need for user authentication means, which must be convenient and reliable at the same time. Nowadays, access control and user authentication are common tasks that are usually performed with tokens or passwords. In the case of handheld devices, user authentication is performed in most cases with pass...

Today, handheld devices in addition to efficiently perform the function for which they were created are also facilitators of all kinds of content through its integrated internet connectivity. The user can access and play multimedia information (pictures, videos, music, podcast, ...), read news, ... and complete educational activities. Regarding the role of learning facilitator, the challenge is...
