Some Misconceptions about Temporal Constraints of MPEG-2 Video Decoding

In this paper, we present results from a study of realistic MPEG-2 video streams to analyze the validity of common assumptions for software decoding. Our analysis identifies a number of misconceptions. We present actual demands based on quality considerations and derive timing constraints for their decoding. We show that standard, fixed timing constraints are restrictive and flexible ones are better suited for MPEG-2 software de-
