摘要： When performing "time warp slice" rendering for a virtual reality display, the application rendering (30) of the images required for the application that requires the virtual reality display is synchronised (35) to the display frame rate and treated as a "normal" priority task (51) in terms of its scheduling on a host processor. The time warp slice rendering (50) to render the time warp "slices" into the display buffer (21) of the display (4) for scanning out (23) as the display panel is being refreshed is effected as a "real time" priority task (58). To do this, the rendering task setup processing that must be performed on the host processor for that rendering task is scheduled using an earliest deadline first scheduling policy and is synchronised (52) to specific, recurring display events (53) that allow the "real time" priority time warp slice rendering task setup processing on the host processor to be triggered at specific points in the scan out period (23) of the display (4).

摘要： The technology described herein relates to a method of generating an encoded output video frame for transmission to an electronic display in which an encoded source video frame is decoded to obtain a decoded source video frame 200a, the decoded source video frame200a is processed to obtain an input video frame200c, and the input video frame200c is encoded to obtain an encoded output video frame for transmission. The method comprises comparing a region of an input video frame 200c with a region of a decoded source video frame200a from which decoded source video frame the input video frame has been obtained, to determine if the region of the decoded source video frame200ais similar to the region of the input video frame200c, and if it is determined that the region of the decoded source video frame200a is similar to the region of the input video frame200c, using a region of the encoded source video frame that corresponds to the region of the decoded source video frame as a region of the encoded output video frame for transmission that corresponds to the region of the input video frame.
摘要翻译：本文描述的技术涉及一种产生编码输出视频帧以传输到电子显示器的方法，其中编码的源视频帧被解码以获得解码的源视频帧200a，解码的源视频帧200a被处理以获得输入视频帧200c，并且输入视频帧200c被编码以获得用于传输的编码输出视频帧。该方法包括将输入视频帧200c的区域与已经从其获得了输入视频帧的解码源视频帧的解码源视频帧200a的区域进行比较，以确定与该区域相似的解码源视频帧区域，并且如果确定解码的源视频帧200a的区域类似于输入视频帧200c的区域，则使用与解码的源视频的区域相对应的编码的源视频帧的区域帧作为用于传输的编码输出视频帧的区域，其对应于输入视频帧的区域。

摘要： A display controller provides an output frame to a display for display by sending respective output surface regions that together form the output frame, each respective region of the output surface being generated from a respective region or regions of one or more input surfaces, to the display. When a new version of an output surface region is generated, the display controller determines whether the output surface region has been unchanged for a period, and if it has, then stores the generated output surface region in a frame buffer. Then, for the subsequent frame, checks are performed to see if the output surface region could have changed. If there is no change the stored version of the output surface region is reused, but if there is a change in the output surface region, the output surface region is regenerated.
摘要翻译：显示控制器通过发送一起形成输出帧的相应输出表面区域将显示器的输出帧提供给显示器，输出表面的每个相应区域从一个或多个输入表面的相应区域或区域生成到显示器。当产生新版本的输出表面区域时，显示控制器确定输出表面区域是否在一段时间内没有变化，并且如果具有，则将生成的输出表面区域存储在帧缓冲器中。然后，对于后续帧，执行检查以查看输出表面区域是否可能已经改变。如果没有变化，则重新使用输出表面区域的存储版本，但如果输出表面区域发生变化，则会重新生成输出表面区域。
