N-Screen Service can be categorized as:

◦ Data Synchronization

Ex. Dropbox, ucloud, box.net

◦ Ceaseless Display

Ex. U+ Box

Framework Layer – seamless computing environment

Application Layer – run on every kind of devices

Human Computer Interaction – display seamlessly

kernel level device driver functioning in remote screen device

Receives and sends data to client side by TCP

Multiple connections to supply duplicated N-Screen at the same time

Virtual Device Driver

Manages multimedia data

Handles playback event and send the information to clients with streaming data

Media Bridging Framework

No computing and communication capability for decoding

Adapter is used to convert received data in RGB format

Legacy Display Device

VIA Pico-ITX

computing enable devices

Run a dedicate program

Network Enable Device

N-Screen service provides users data, program, and display synchronization

The proposed framework lets users have seamless screen displayed on the virtualized screen devices
