Abstract: Techniques are described for determining a region to be updated in a frame based on positional changes of one layer from frame-to-frame. The positional changes may be displacement of a layer or removal of a layer from one frame to the next. In addition to the information of the positional changes, the techniques also utilize all areas for which the image content changed, but the position did not, for determining the region to be updated.

Abstract translation: 描述了基于一帧从帧到帧的位置变化来确定帧中要更新的区域的技术。 位置变化可以是层的位移或从一个框架到下一个框架的移除。 除了位置变化的信息之外，这些技术还利用图像内容改变的所有区域，但是位置没有用于确定要更新的区域。

Abstract: A method for display mirroring is described. The method includes computing an updating region size for one or more application layers of a screen image, the updating region area regions of interest being updated on the screen image less any overlap between the regions of interest. The method also includes determining that the updating region size plus a previous frame size is less than a frame buffer size. The method further includes determining that there are sufficient resources available to combine the previous frame with the updating region. The method additionally includes generating a current frame by combining the previous frame and the updating region. The method also includes sending the current frame to a mirrored display.

Abstract translation: 描述了显示镜像的方法。 该方法包括计算屏幕图像的一个或多个应用层的更新区域大小，在屏幕图像上更新感兴趣的更新区域区域，减少感兴趣区域之间的任何重叠。 该方法还包括确定更新区域大小加前一帧大小小于帧缓冲区大小。 该方法还包括确定有足够的资源可用于将先前帧与更新区组合。 该方法还包括通过组合前一帧和更新区域来生成当前帧。 该方法还包括将当前帧发送到镜像显示器。
