Many countries have developed different mobile TV standards such as DVB-H, DMB, MediaFLO, OneSeg, and ATSCM/H. In this paper, we compare different mobile TV standards from the viewpoint of video and audio encoding, data encapsulation, transmission network, and advantages and disadvantages of each technology. Also we propose future mobile TV applications 3-D mobile TV to provide backward compati...

Today, we see a strong demand for real-time information, with a rapid growth of m-learning. We also see that there are many educational resources on the Internet. Learning objects (LOs) are designed as a means of reusing these resources. Most of these LOs are built for e-learning systems based on desktop computers, which prevents their use on mobile devices. A LO is an area that is open to rese...

The computer industry has defined the IEEE 802.16 family of standards that will enable mobile devices to access a broadband network as an alternative to digital subscriber line technology. As the mobile devices join and leave a network, security measures must be taken to ensure the safety of the network against unauthorized usage by encryption and group key management. IEEE 802.16e uses Multica...

Mobile TV Systems/Standards With Mobile TV, users enjoy live and/or ondemand TV using their own mobile devices, such as TV-capable wireless phones and PDAs. The delivery of Mobile TV can be achieved through terrestrial broadcast, satellite broadcast, a combination of terrestrial and satellite broadcasts, and cellular networks. Table 1 lists popular systems/standards for each of one these catego...

Telecare and especially Mobile Care Systems are getting more and more popular.
