Abstract
一种帧内预测模式的解码方法,包括:从码流中解析第一标识,所述第一标识用于指示当前解码单元的帧内预测模式属于第一模式集合,其中,所述第一模式集合是多个预设候选帧内预测模式的子集,所述第一模式集合包括所述当前解码单元的可用的预设位置的邻域重建单元的帧内预测模式和至少一个非方向性预测模式;当所述第一标识确定所述当前解码单元的帧内预测模式属于所述第一模式集合时,从所述码流中解析第二标识,所述第二标识用于指示所述第一模式集合中作为所述当前解码单元的帧内预测模式的候选帧内预测模式;当所述第一标识确定所述当前解码单元的帧内预测模式不属于所述第一模式集合时,从所述码流中解析第三标识,所述第三标识用于指示所述当前解码单元的帧内预测模式属于第二模式集合,其中,所述第二模式集合是所述多个预设候选模式的子集,所述第二模式集合和所述第一模式集合无交集,所述第二模式集合中的候选帧内预测模式包括表征所述第一模式集合中的方向性预测模式的邻近预测方向的帧内预测模式。
