簡単なローカル予測子を用いる改善された重要度フラグ符号化の方法及び装置
Document Type and Number:
Japanese Patent JP7034101
Kind Code:
B2
Abstract:
Significance flags in advanced video compression systems are coded using contexts adaptive to the last N significance flags coded taken in a scanning order. One embodiment uses the last N significance flags in scanning order as a predictor to determine which of a plurality of sets of significance flag contexts to use for coding subsequent significance flags. A second embodiment uses the last N significance flags in scanning order as a predictor in order to modulate the probability value associated with significance flag contexts that are used to code significance flags for future coding.
