Paradigm shifts in modern ICT era and future trends
Information and communication technologies (ICT) have become more mature after its development for more than half a century. We are in a new era in which ICT research has shifted its focus from technology development to novel applications. For example, digital technologies have been widely applied to speech, audio, video and graphics in various commercial applications today. Furthermore, the availability of the broadband wired/wireless Internet infrastructure and the cloud computing facilities has changed the way of web-based services. This lecture will address the following four major paradigm shifts in this modern IT era: • From the analog implementation to the digital implementation • From PC-centric to cloud/network-centric • From one-way broadcasting to two-way interaction • From HW/SW/infra-structure provision to contents and value-added services
