Abstract	An improved slice group mapping method for inter frames using FMO in H.264/AVC is proposed in this paper. To avoid the extra cost introduced by updating the slice group map, the fast mode decision and early Skip mode decision are applied for the first encoding pass, and only the features that are available at the stage of early Skip mode decision and before the seven mode decision are used for the classification. The proposed method can be applied with UEP schemes for mobile channel transmission. With ideal UEP schemes, it can improve PSNR for up to 4dB for the Foreman sequence and up to 8dB for the News sequence under an erroneous channel. The computation time cost can be saved by 30% for News and 40% for Foreman compared with conventional methods.
