Abstract
A method and apparatus for enabling compression of a stream of pictures according to a target bit rate are described. A first configuration parameter for a first portion is determined based at least in part on a first relative weight of the first portion with respect to a first set of N portions, where the first set of N portions includes the first portion and N-1 portions which succeed the first portion. A second configuration parameter for a second portion of a second picture is determined based at least in part on a second relative weight of the second portion with respect to a second set of M portions of pictures, where the second set of M portions includes a subset of the N-1 portions from the first set and zero or more additional portions of pictures from the stream of pictures.
