Abstract: The performance of distributed systems can be improved when a server remotely controls off-screen surfaces at a client coupled to the server via a communications network. The server instructs the client to form an off-screen surface exhibiting a number of particular attributes. The client selects and allocates a particular memory region and forms the off-screen surface therein, as instructed by the server. The server subsequently provides the client with an indicia of graphical data and instructs the client to locate the graphical data and to copy the data into the off-screen surface. In response to an error condition, the server transmits a duplicate of the off-screen surface to the client with instructions to update the client's on-screen surface using this duplicate surface.

Abstract: It is expected to increase the size of a display panel and the number of tones to be displayed on the display panel, and it is requested to use a display panel displaying M (M>3) types of colors. This requires a large memory capacity and makes a circuit for performing signal conversion complex due to an increase in the amount of data to be subjected to the signal conversion. An image memory stores image data compressed at a fixed compression rate, and the signal conversion is performed on the compressed image data. This technique reduces a memory capacity and simplifies a signal conversion circuit. The signal conversion makes it possible to improve color reproducibility of an image displayed and the quality of the image due to smoothing of the outline of the image. In the case of a display panel having sub-pixels displaying M types of colors, the signal conversion is performed on a compressed signal for each sub-pixel to improve the quality of an image.

Abstract: Disclosed are methods and systems for interfaces between video applications and display screens that allow applications to intelligently use display resources of their host device without tying themselves too closely to operational particulars of that host. A graphics arbiter provides display environment information to the video applications and accesses the applications' output to efficiently present that output to the display screen, possibly transforming the output or allowing another application to transform it in the process. The graphics arbiter tells applications the estimated time when the next frame will be displayed on the screen. Applications tailor their output to the estimated display time, thus improving output quality while decreasing resource waste by avoiding the production of “extra” frames. The graphics arbiter tells an application when its output is fully or partially occluded so that the application need not expend resources to draw portions of frames that are not visible.
