Executive Summary of Whitepaper
Cloud rendering of modern graphics is typically performed via remote hardware rendering and pixel-based video compression techniques for image transmission. These solutions perform poorly, profligately expending both system and network resources. In response, Ascender Technologies developed novel enabling technology where the rendering of pixels is performed only on the local client, which makes for a much more affordable solution without expensive graphical hardware in the cloud. In addition, Ascender’s compression techniques reduce the networking overhead, typically by over an order of magnitude.

The trend in modern graphical rendering systems is to a higher quality visual experience. Frames are generated at a very fast rate (~60 fps) and a complete re-rendering is performed for each frame. In addition, the size and density of displays have grown over the previous generation, greatly increasing the number of pixels generated for each frame. These combined changes in technology challenge the prevailing methods of providing remote graphics. In order to meet networking bandwidth constraints, remote pixel based-methods typically are forced into compromises in:

     ○ Latency       Resolution      Image Quality       Frame Rate

Ascender’s enabling technology does not suffer from any of the above compromises and is significantly less expensive to implement.

Ascender’s enabling technology is applicable to a wide-range of systems and encompasses many use cases. In this white paper some use cases are considered:

Cloud Gaming: Unlike server-side pixel renderers, such as the Nvidia Grid, which employs expensive hardware to render pixels in the cloud, extensive bandwidth to transmit an H264 video stream and nevertheless compromises all four performance parameters, Ascender’s enabling technology:
  • Uses less cloud resources
  • Does not need remote GPU hardware
  • Uses lower network bandwidth
  • Does not compromise performance

Cloud Android Apps: Android apps can be run in the cloud and the graphics displayed on the local device. Five different Android rendering API’s (Canvas, OpenGLRender, OpenGL ES 2.0, OpenGL ES 1.x and Skia) were implemented and tested giving coverage of a large percentage of Android apps.

Other Use Cases: We also briefly consider other use cases: App Library / Subscription Model, Purchase / Rental Models, Remote Enterprise Applications, Set-Top Boxes, Automated Testing and WebGL Browser Based Implementations.
