Abstract
A method for allocating bits to be used to compression code digital data signals representing a group of pictures in a motion video sequence. The pictures within each group of pictures to be coded are identified as being one of a plurality of different picture types. The total number of bits to be used in compression coding the group of pictures is determined based on a fixed target bit-rate. The number of bits for use in compression coding a picture in said group of pictures is allocated from said total number of bits using a number of pictures in each of the plurality of picture types in order to produce an allocation of bits which meet the fixed target bit-rate.
