Abstract
Decoding MPEG-2 video streams imposes hard realtime constraints for consumer devices such as TV sets. The freedom of encoding choices provided by the MPEG-2 standard results in high variability inside streams, in particular with respect to frame structures and their sizes. In this paper, we identify realistic timing constraints demanded by MPEG-2 video decoding. We present results from a study of realistic MPEG-2 video streams to analyze the validity of common assumptions for software decoding and identify a number of misconceptions. Furthermore, we identify constraints imposed by frame buffer handling and discuss their implications on decoding architecture and timing constraints.
