Timing constraints of MPEG-2 decoding for high quality video: misconceptions and realistic assumptions

D. Isovic, G. Fohler, L. Steffens
15th Euromicro Conference on Real-Time Systems, 2003. Proceedings.  
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.  ...  In this paper, we identify realistic timing constraints demanded by MPEG-2 video decoding.  ...  Acknowledgements The authors wish to thank the reviewers for their fruitful comments which helped to improve the quality of the paper. Further thanks go to Clemens Wüst and Martijn J.  ...

Asynchronous transfer of video

G. Karlsson
1996 IEEE Communications Magazine  
Brief overviews of video coding, rate control, multiplexing, as well as delay, error and loss control are given.  ...  Various video services are expected in the future, enabled by the rapid development in video coding and broadband network technology.  ...  The general topic of packet video is thus to code and asynchronously transfer video signals under quality constraints.  ...

Flexible Media Processing in Resource Constrained Real-Time Systems

Damir Isovic
2006 Eighth IEEE International Symposium on Multimedia (ISM'06)  
MPEG-2 processing puts high demands on audio/video quality, which is achieved by continuous and synchronized playout without interrupts.  ...  The MPEG-2 standard for video coding is predominant in consumer electronics for DVD players, digital satellite receivers, and TVs today.  ...  Furthermore, we propose realistic timing constraints demanded by high quality MPEG-2 software video decoding.  ...

A Markov framework for error control techniques based on selective retransmission in video transmission over wireless channels

Leonardo Badia, Nicola Baldo, Marco Levorato, Michele Zorzi
2010 IEEE Journal on Selected Areas in Communications  
Thus, our framework can be used as an effective tool to understand the behavior of error control techniques applied to video transmission over wireless, and eventually identify design guidelines for such  ...  We present a framework, based on Markov models, for the analysis of error control techniques in video transmission over wireless channels.  ...  This quality evaluation can be translated into a more common measurement of PSNR, which is reported in Fig. 6 and also compared with simulation results for a realistic video transmission.  ...

Quality aware MPEG-2 stream adaptation in resource constrained systems

D. Isovic, G. Fohler
Proceedings. 16th Euromicro Conference on Real-Time Systems, 2004. ECRTS 2004.  
In this paper, we present a method for quality aware frame selection for MPEG decoding under limited resources, based on realistic timing constraints for the decoding of MPEG streams.  ...  Results from study based on realistic MPEG-2 video underline the effectiveness of our approach.  ...  Acknowledgements The authors wish to express their gratitude to Liesbeth Steffens and Clemens Wüst for fruitfull discussions and to the reviewers for helpful comments.  ...
