A Design and Implementation of Multi-source Wi-Fi Display Model on Android Devices

Smart mobile devices and wireless network complement each other, Smart Home emerges gradually. Lots of developers start to study the connection issue of mobile devices and HDTV. Besides wire solutions to the issue, vendors provide wireless display solutions over Wi-Fi, such as AirPlay provided by Apple, DLNA proposed by DLNA, and Wi-Fi Display designed by Wi-Fi Alliance. HDTVs can only create one-to-one mapping to smart mobile devices under standard of Wi-Fi Display and display one remote source screen content at the same time. Due to different screen resolutions, huge display space is wasted when mobile devices vertically display their screens on remote HDTVs. We propose a wireless multi-source display architecture in this paper and implement a prototype which can present one or more source screens over Wi-Fi based on Android. With this proposition, we raise the screen utilization rate, increase scenarios, and improve user experience.
