Abstract
Apparatus and method for detecting scene changes using data sets gathered from a 3D pipeline. For example, one embodiment of an apparatus comprises: a 3D graphics engine to render a plurality of frames including a current frame and a prior frame; and a scene change detector to retrieve data sets from the 3D graphics engine, the data sets associated with the current frame rendered by the 3D graphics engine, the scene change detector to analyze the data sets in view of corresponding data sets from the prior frame to determine a first type of encoding to be used for encoding the current frame prior to transmission over a network.
