In this paper, we provide an analysis of performance of the scalable extension of the H.264/AVC video codec. We assume a fixed display scenario at full HD resolution with a constant frame rate. The encoded bit stream consists of one Coarse Grain Scalability (CGS) and one Medium Grain Scalability (MGS) layer with three sublayers, allowing for creating four quality layers from the complete bit stream. Hierarchical coding is employed, which results in dyadic decomposition of temporal layers. In order to increase the granularity of quality layers, the packets are selectively dropped from appropriate quality and temporal layers. We provide a performance analysis of such approach, compare the rate distortion performance to a mainstream H.264 encoder and analyze the composition of the bit stream at the considered operation points. Our findings show that quality enhancement of temporal layers has different effect on the overall performance depending on which temporal layer is enhanced.
