Embodiment Construction
[0027] (1) Calculate the target bit number ΣT of all macroblocks in the current frame according to the frame layer code rate allocation strategy.
[0028] (2) Calculate the number of header information bits ΣM of all macroblocks in the current frame according to the following header information prediction model
[0029] ΣM = h p + m c ′ × m p m p ′ - - - ( 1 )
[0030] where h p is the slice layer of the previous frame and the number of header information bits of the higher layer after transcoding, m c t , m p t and m p are the number of macroblock layer header information bits of the current frame after transcoding, the previous frame before transcoding, an...
