Abstract: System and method of displaying images in spatial/temporal superresolution by multiplicative superposition of cascaded display layers integrated in a display device. Using an original image with a target spatial/temporal resolution as a priori, a factorization process is performed to derive respective image data for presentation on each display layer. The cascaded display layers may be progressive and laterally shifted with each other, resulting in an effective spatial resolution exceeding the native display resolutions of the display layers. Factorized images may be refreshed on respective display layers in synchronization or out of synchronization.

Abstract: A method, web browser, and system for co-browsing online content is disclosed. Embodiments enable a co-browsing session between web browsers running on different computer systems using a respective peer proxy server on each computer system. A primary peer proxy server running on a first computer system communicates directly with a web server, while communications from other peer proxy servers running on other computer systems are directed through the primary peer proxy server. The primary peer proxy server accesses online content from the web server for presentation using a web browser running on the first computer system, where the online content is presented simultaneously with modified online content presented using web browsers running on the other computer systems. The online content and the modified online content may be synchronized based upon a web server response associated with a browser event communicated to the web server.

Abstract: An aspect of the present invention proposes a novel approach that can reduce the total number of the overlays to be composited during the display of graphical output in a mobile computing device. As a result, the total number of memory bandwidth and the usage of a graphics processing unit by a pre-compositor can be decreased significantly. According to one embodiment, this new approach is implemented with a display panel with embedded memory which supports a partial update, or refresh feature. Which such a feature, the layer compositor (typically either the display controller or GPU) is able to keep track of actively updating regions of a display panel by checking if each layer has new content to be displayed.
