A particular method includes receiving video content at a set-top box device. Scene data defining a three-dimensional scene is accessed, where the scene data includes object data defining at least one three-dimensional graphical object, and where the scene data is accessed based at least in part on information associated with the video content. The method further includes processing the object data to render the at least one three-dimensional graphical object. The rendered at least one three-dimensional graphical object is overlaid on a portion of the video content, thereby generating dynamically modified video content. The method includes sending the dynamically modified video content to a display device.
