1. A video processing device, comprising: a video processor configured to facilitate: inputting preprocessed digital video data ready for further processing by an encoder or a transcoder, compressing the preprocessed digital video data to form compressed digital video data, and outputting the compressed digital video data; and a video preprocessor operable to receive digital video raw data, configured to facilitate: preprocessing a macroblock of the digital video raw data so as to output the preprocessed digital video data ready for an encoder or transcoder of the video processor when the macroblock does not indicate SKIP, and not preprocessing the macroblock of the digital video raw data when the macroblock is a SKIP macroblock indicating SKIP, but jumping to process the SKIP macroblock by an entropy encoder of the video processor instead.
