专利汇可以提供Block prediction method using improved direct mode专利检索,专利查询,专利分析的服务。并且The present invention discloses a method of predicting a current block (B C ') of a bi-predictive picture (B 5 ) in direct mode, comprising:

obtaining a forward motion-compensated block (B f ) pertaining to a forward reference picture (P 1 ; P 4 ) by using a forward (MV f ) motion vector, and obtaining a backward motion-compensated block (B b ) pertaining to a backward reference picture (P 7 ) by using a backward (MV b ) motion vector; and
predicting the current block (B c ') of the bi-predictive picture (B 5 ) using a sum of the forward motion-compensated block (B f ) with a first coefficient and the backward motion-compensated block (B b ) with a second coefficient,
wherein the first and second coefficients are derived using a picture order count (T b ) of the backward reference picture (P 7 ), a picture order count (T c ) of the bi-predictive picture (B 5 ) and a picture order count (T f ) of the forward reference picture (P 1 ; P 4 ).,下面是Block prediction method using improved direct mode专利的具体信息内容。
