Today, mobile devices like smartphones and tablets are becoming more powerful and exhibit enhanced 3D graphics performance. However, the overall computing power of these devices is still limited regarding usage scenarios like photo-realistic gaming, enabling an immersive virtual reality experience or real-time processing and visualization of big data. To overcome these limitations application streaming solutions are constantly gaining focus. The idea is to transfer the graphics output of an application running on a server or even a cluster to a mobile device, conveying the impression that the application is running locally. User inputs on the mobile client side are processed and sent back to the server. The main criteria for successful application streaming are low latency, since users want to interact with the scene in near real-time, as well as high image quality. Here, we present a novel application framework suitable for streaming applications from high-end machines to mobile devices. Using real-time ETC1 compression in combination with a distributed rendering architecture we fully leverage recent progress in wireless computer networking standards (IEEE 802.11ac) for mobile devices, achieving much higher image quality at half the latency than other in-home streaming solutions.(original abstract)
