  • executing an HTML-based virtual client application;

    using the HTML-based virtual client application to;

    traverse a Document Object Model (DOM) tree to identify differences between two sequential images in sequential video frames of a sequence of video frames to render a rendered image corresponding to a video frame, the rendered image associated with HTML commands; and

    generate an HTML wrapper for the rendered image that includes data encoded in accordance with the differences identified by traversing the DOM tree, comprising converting the HTML commands to HTML primitives, wherein the HTML primitives are selected from a subset of available HTML commands; and

    sending the HTML wrapper to the client device to be processed by an HTML-based application on the client device to enable the image to be displayed at a display coupled to the client device.
