ABSTRACT:
A method and apparatus for encoding pictures of a moving pictures sequence according to an overall target bit-rate, such as in a MPEG video encoder. Each picture has an assigned picture coding type for which a quality factor is adaptively determined according to past bit usages, so that bits can be adaptively allocated amongst picture types for optimizing visual quality of the encoded pictures.
