Abstract
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.
