Abstract:

本发明公开了一种在维持编码效率总体不变的条件下,减少应用的上下文模型个数,删除冗余模型,节省系统资源的面向HEVC参数编码的上下文简化方法,当对coeff_abs_level_greater1_flag元素的24个表示亮度和8个表示色度的上下文模型进行编码时,24个上下文模型分成6组且每组4个,8个上下文模型分为2组且每组4个,编码采用公式:ctxIdxInc=(ctxSet*3)+(greater1Ctx+1)>>1,其中ctxSet是上下文的组数编号,当是表示亮度的上下文模型时值为0-5,当是表示色度的上下文模型时值为0-1,greater1Ctx是用于从组内选择上下文的参数,值为0-3。
