Abstract
The present invention provides an optimal processing pipeline suitable for high quality video and graphics processing. According to the invention, color key extraction is performed before actual processing and transforming of the video/graphics data. This substantially minimizes the amount of artifacts in composed pictures. In accordance with the present invention, a video/graphics data processing pipeline is provided. The pipeline comprises a pre-processing circuit that is configured to pre-process a stream of digital video/graphics data and output pre-processed data; a color key processing circuit, operably coupled to the pre-processing circuit, that is configured to extract a color key from the pre-processed data and output resulting data; and a processing/transforming circuit, operably coupled to the color key processing circuit, that is configured to process and transform the resulting data.
