The cloud virtualization and N-Screen technologies related to open cloud environment are promoting to change legacy IT service architecture. The technologies are very useful to transform old service architecture to new one. With the technologies, Smart TV and its service architecture can be improved. Smart TV has been discussed as a promising device of Post PC category to handle various user needs by adding computing power to general TV. Smart TV is already commercialized and used in web-surfing, ondemand requests on movies combined with Internet enabled set-top box device. There has been specific approach to increase its usability by adding TV apps for specific Smart TV hardware. However, as Post PC perspective, current Smart TV system and architecture are lack of flexibility and need new paradigm. The architecture should provide office-work friendly environment, cover various OS-dependent users and apps based on Android OS & iOS together, and support legacy IT resources. In this paper, we suggest new platform design to achieve the goal to make Smart TV as Post PC device based on emerging cloud virtualization & N-Screen technologies and develop a simple set to test main functions of the platform.
