Cloud-based Dynamic Tiled Display Adapting to Grouping by Distinction of Mobile Devices

Mobile devices such as mobile phones and tablets are daily devices as personal viewing of various streaming. They have potentials as a big virtual screen by a tiling display. It is important to keep video quality among tiled video displays in the case of cloud video streaming through the Internet. To solve this issue, we design and develop a mobile tiled display system which supports dynamic tiling adapting to the situation of mobile devices and network status. The proposed system has a dynamic grouping mechanism by devices properties and network status using attribute-based cryptography. Only authorized devices can join the group of the tiled display. Since the video resource is assumed to be on clouds, we introduce edge computing in the architecture of the system and it enables effective processing of video streaming for real-time adapting to variation of distinction of devices.
