Abstract: A video encoding device includes a pixel offset pre-calculation part configured to generate a loop-filtered pixel from a coding information and at least one of a source pixel, a predicted pixel and a restructured pixel, and configured to generate an offset from the loop-filtered pixel by performing a sample adaptive offset operation. The video encoding device also includes an entropy coding part configured to generate a bit stream from the offset.
