Abstract: A system, apparatus and method are disclosed for separating a current frame of a composite video signal into a luminance signal and a chroma signal. A relative chroma correlation value is generated using a plurality of lines of the current frame. A weighted sum of inter-line pixel differences of the current frame is generated using the relative chroma correlation value. A frame difference signal is generated by subtracting a previous frame of the composite video signal from the current frame. A detected motion signal is generated that corresponds to motion detected in the current frame. The weighted sum of inter-line pixel differences, the frame difference signal, and the detected motion signal are combined to generate the chroma signal. The chroma signal is subtracted from the current frame to generate the luminance signal.

Abstract: A system is disclosed for reducing artifacts in images and video, such as ringing or halo artifacts. The system may include an edge detector and a gain controller. The edge detector may create an edge image used by the gain controller to create a gain image, and the gain image may be used to reduce artifacts in an image. The gain controller may, for a current pixel in the edge image, compute the maximum value of the edge image over a window containing the current pixel. The gain controller may also perform averaging to determine a maximum edge value and a current edge value, and may also use a ratio of the current edge value and the maximum edge value to determine a gain to be applied to a pixel of an image.

Abstract: A method of processing video frame data includes the steps of: receiving a video frame; partially decoding the video frame; fully decoding the video frame to produce macroblocks; determining video data parameters from the partially decoded video frame or both the partially and fully decoded video frame; and encoding the macroblocks based on the determined video data parameters to provide a compressed video frame for subsequent display.
