H.264/AVC encoder complexity is remarkable mainly due to variable block size motion estimation (ME) and exhaustive rate distortion optimization (RDO). This makes real-time video coding very difficult. In this paper, a novel fast mode decision algorithm for P-slices is presented to reduce the computational load. Based on the temporal and spatial correlation between macroblocks, a four paths prediction...
Through experiments on combinations of coding tools included in H.264/AVC, we obtain an optimal combination of coding tools for the mobile multimedia broadcasting application. Although H.264/AVC has defined several profiles and levels for different applications, the partitions are still imprecise. The mobile communication network is usually with limited bandwidth and different kinds of fading and...
In the scalable video coding extension of H.264 standard, the concept of inter-layer prediction is adopted to reduce the redundancy between the base layers and the enhancement layers. Thus, additional coding modes should be calculated during the macroblock mode decision procedure at the enhancement layers. It increases the computational complexity and may obstruct its practical applications. A fast...
