According to the present invention, CABAC encoding or decoding is applied to a current bin of a binary data of a current coding symbol according to a current probability for a binary value of the current bin and a current range associated with the current state of arithmetic coder. An LPS probability index corresponding to an inverted current probability or the current probability is derived depending on whether the current probability is greater than 0.5. A range index is derived for identifying one range interval containing the current range. An LPS range is then derived using one or more mathematical operations comprising calculating a multiplication of a first value related to the LPS probability index and a second value related to the range index n."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for range derivation in context adaptive binary arithmetic coding","description":"A method and apparatus of entropy coding of coding symbols using Context-Based Adaptive Binary Arithmetic Coder (CABAC) are disclosed.
