Casting windows to Android based on hybrid encoder model

Along with the development of mobile internet, there are increasing devices running on top of mobile operating systems among which Android is the most popular on the earth. Ranging from screen size as big as modern TV to screen size as small as smartphone, Android is ubiquitous in mobile computing and is prevailing in every corner of our daily life. On the other hand, traditional desktop operating system like Windows owns more professional applications and stronger computing ability which are not available on devices running on Android. Hence, in this paper, we propose a hybrid encoder model to cast Windows screen to Android. Compared to classic way of solving this problem, our method is more efficient in screen casting in that a heuristic decision is made to determine whether traditional VNC mode or streaming mode is activated. The experiments between the server using our hybrid encoder model and classic VNC server show that our method takes less network bandwidth and renders more frames when sending multimedia over wireless network.
