Abstract

Video applications are subject to throughput and real-time constraints. Different components of the end-to-end system, such as encoder, decoder, buffers and network components have an impact on the end-to-end latency that needs to be respected to avoid severe quality degradation. The semantics of MPEG-4 play an important role when analyzing both the indivual and end-to-end latency constraints. Missing the individual or global deadline of different kind of video information has a very different impact on the end-video quality. This paper introduces the impact of the semantic dependencies, such as frame types, frame coding technique and stream structure, on the timing of MPEG-4 playout.
