摘要： A video processing device includes a video preprocessor and a video processor. The video processor is 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. The 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.
