Abstract: A system and method for providing video compression that includes encoding using an encoding engine a YUV stream wherein Y, U and V color values are encoded in parallel and patching together the Y, U and V color streams to form a compressed YUV output stream. The encoding engine further includes encoding each color value of the YUV stream in parallel using parallel encoding engines and a control engine for controlling operation all of the encoding engines in parallel. The YUV stream has an average bits per pixel value that varies from a first value to a second value that is double the first value. The encoding engine includes encoding the YUV stream in generally the same amount of time regardless of the average bits per pixel value.

Abstract: A processing apparatus is provided that includes an encoder configured to encode current frames of video data using previously encoded reference frames and perform motion searches within a search window about each of a plurality of co-located portions of a reference frame. The processing apparatus also includes a processor configured to determine, prior to performing the motion searches, which locations of the reference frame to reload the search window according to a threshold number of search window reloads using predicted motions of portions of the reference frame corresponding to each of the locations. The processor is also configured to cause the encoder to reload the search window at the determined locations of the reference frame and, for each of the remaining locations of the reference frame, slide the search window in a first direction indicated by the location of the next co-located portion of the reference frame.
