Abstract
A method and apparatus for encoding bit code utilizing context dependency simplification to reduce dependent scans. The method includes retrieving at least one 2 dimensional array of transform coefficient, transforming the at least one 2 dimensional array of transform coefficient to a 1 dimensional coefficient scanning using a diagonal scan in a fixed direction, utilizing the at least one 1 dimensional array of transform coefficients for context selection based on fewer than 11 neighbors, potentially selected based on scan direction, slice type, coding unit type and binarization, and performing arithmetic coding to generate coded bit utilizing context selection and binarization.
