Abstract:
A method for lossless compression of video data is provided. The method includes; receiving video data including a plurality of video frames; dividing each of the plurality of video frames into a plurality of compression regions, wherein each compression region includes at least one compression unit; processing each compression region of a first video frame by: providing a prediction mode parameter set including a plurality of prediction modes; performing prediction processing on at least a part of the compression units using the prediction modes, and determining usage of the prediction modes; and selecting at least a part of the prediction modes as a preferred prediction mode parameter set based on the usage; performing prediction processing on subsequent video frames using the determined preferred prediction parameter mode set to obtain coding blocks; and performing entropy coding processing on the coding blocks to obtain compressed video data.
