20100321402 | DISPLAY UPDATE FOR A WIRELESS DISPLAY DEVICE - Embodiments of partial update for a wireless display device include providing an update information message identifying a location of the partial update and the changed image data. A display source identifies changes in image data stored in a frame buffer, generates an update information message to identify the location of the changed image data and to provide the changed image data. A display sink receives the update information message and merges the changed image data with image data stored in a local frame buffer. | 12-23-2010 |
20110078536 | Using Motion Change Detection to Reduce Power Consumption of Display Systems - Image data, such as graphics, text, and video may be conveyed from a host to a remote display. In some cases, an analysis of successive frames may be undertaken to determine whether motion exists between those frames. In one embodiment, this motion detection may involve the use of an error correction code, such as a cyclic recovery check. This may enable a relatively efficient, low cost determination of whether motion is occurring. If motion is not occurring, motion estimation may be simplified in some cases and, in some cases, refreshing of the display may be curtailed, for example, using a local frame buffer associated with the display. | 03-31-2011 |
20110157198 | Techniques for aligning frame data - Techniques are described that can used to synchronize the start of frames from multiple sources so that when a display is to output a frame to a next source, boundaries of current and next source are aligned. Techniques are useful to avoid visual distortions when changing from a first video source to a second video source. | 06-30-2011 |
20110157202 | Techniques for aligning frame data - Techniques are described that can used to synchronize the start of frames from multiple sources so that when a display is to output a frame to a next source, boundaries of current and next source are aligned. Techniques attempt to avoid visible glitches when switching from displaying a frame from a first source to displaying frames from a second source even though alignment is achieved by switching if frames that are to be displayed from the second source are similar to those displayed from the first source. | 06-30-2011 |
20120254645 | CONTROL OF PLATFORM POWER CONSUMPTION USING COORDINATION OF PLATFORM POWER MANAGEMENT AND DISPLAY POWER MANAGEMENT - Control of platform control of platform power consumption using selective updating of a display image. An embodiment of an apparatus includes a display controller to transfer pixel data from a frame buffer to a video display and a detection element to track updates to the frame buffer, the detection element to identify a portion of the pixel data that has been changed from a previous image, where the display controller is to provide the video display with the identified portion of the pixel data. | 10-04-2012 |
20130314386 | DISPLAY UPDATE FOR A WIRELESS DISPLAY DEVICE - Embodiments of partial update for a wireless display device include providing an update information message identifying a location of the partial update and the changed image data. A display source identifies changes in image data stored in a frame buffer, generates an update information message to identify the location of the changed image data and to provide the changed image data. A display sink receives the update information message and merges the changed image data with image data stored in a local frame buffer. | 11-28-2013 |
20140132616 | HYBRID DISPLAY FRAME BUFFER FOR DISPLAY SUBSYSTEM - A hybrid display frame buffer for a display subsystem. An embodiment of an apparatus a first logic to split a video image into a first data portion and a second data portion; a display frame buffer including a first memory component having a first type of memory and a second memory component having a second type of memory, the first logic to write the first data portion to the first memory component and the second data portion to the second memory component; and a second logic to read the first data portion from the first memory component and the second data component from the second memory component, and to combine the first data portion and the second data portion to generate a combined video image. | 05-15-2014 |
20140168241 | TECHNIQUES FOR MANAGING SYSTEM POWER USING DEFERRED GRAPHICS RENDERING - An apparatus may include a memory to store one or more graphics rendering commands in a queue after generation. The apparatus may also include a processor circuit, and a graphics rendering command manager for execution on the processor to dynamically determine at one or more instances a total execution duration for the one or more graphics rendering commands, where the total execution duration comprises a total time to render the one or more graphics rendering commands. The graphics rendering command manager also may be for execution on the processor to generate a signal to transmit the one or more graphics rendering commands for rendering by a graphics processor when the total execution duration exceeds a graphics rendering command execution window. | 06-19-2014 |
20140267336 | DATA TRANSMISSION FOR DISPLAY PARTIAL UPDATE - Data transmission for display partial update. An embodiment of an apparatus includes a display controller to transfer pixel data from a frame buffer to a video display and to select a granularity of a plurality of granularities for units of data for the transfer of the pixel data, and a detection element to track updates to the frame buffer, the detection element to identify at least a first damage area of the pixel data that has been changed from a previous image, wherein the display controller is to provide the video display with the identified first damage area of the pixel data in more or more units of data of the chosen granularity. | 09-18-2014 |
