Abstract: A codec according to an exemplary embodiment includes a codec processor which receives a current frame, determines a type of a received current frame, and sets rate control parameters of the current frame, and a bit-rate estimator which allocates total target bits to a first group of picture (GOP) including the current frame, and allocates a target bit to each of frames included in the first GOP based on a determined type of the current frame and set rate control parameters.
