提出了一种改进的H.264/AVC帧间FMO切片组映射方法。为了避免通过更新切片组映射引入的额外成本，快速模式决策和早期跳过模式决策被应用于第一编码通道，并且仅在早期跳过模式决策阶段和在七模式决策之前可用的特征被用于分类。所提出的方法可以应用于移动的信道传输的UEP方案。在理想的UEP方案下，在错误信道下，它可以将Foreman序列的PSNR提高高达4dB，将News序列的PSNR提高高达8dB。与传统方法相比，News和Foreman的计算时间分别节省了30%和40%。
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.
