Different models for P and SB pictures are defined for a better QP and MAD estimation. Furthermore, a novel saw-tooth shaped model of target buffer level has also been introduced for a proper bit allocation in GOP structures with SB pictures. Our experimental results show that this proposal outperforms the reference software RC in terms of buffer occupancy and target bit rate adjustment at the expense of slight quality reduction.application/pdfengVideo codingH.264bit allocationbit rate adjustmentrate control algorithmreference softwaresaw-tooth shaped modelstored-B picturestarget buffer levellow-delayresearch articleTelecomunicaciones10.1109/ICASSP.2007.366117open access
