Complexity scalable MPEG-2 to WMV transcoder with adaptive error compensation

Guobin Shen, Yuwen He, Wanyong Cao, Shipeng Li
2006 IEEE International Symposium on Circuits and Systems  
The proposed transcoding architectures can be straightforwardly applied to the MPEG-2 to MPEG-4 transcoding applications due to the significant overlap between the MPEG-4 and WMV coding technology.  ...  In this paper, we study the problem of video transcoding from MPEG-2 to WMV format, together with several desired functionalities such as bit rate reduction etc.  ...  Fig. 4 . 4 Proposed adaptive error compensation and dynamic switch transcoder for MPEG-2 to WMV transcoding. Fig. 5 .Fig. 6 . 56 Comparisons of different transcoding schemes.  ...

Multimedia stream adaptation services [article]

Andreas Schorr, Universität Ulm, Universität Ulm
2016
Furthermore, existing adaptation services support only a limited set of media formats and adaptation operations, and they are usually tightly coupled with a certain communication infrastruture.  ...  availability, and can be easily enhanced with new functionality.  ...  For instance, one record would be registered for a transcoding service from MPEG-2 to MPEG-4, a second record would be registered for a transcoding service from MPEG-2 to M-JPEG, and a third one would  ...

Energy–Quality–Cost Tradeoff in a Multimedia-Based Heterogeneous Wireless Network Environment

Ramona Trestian, Olga Ormond, Gabriel-Miro Muntean
2013 IEEE transactions on broadcasting  
The results show how by using Adapt-or-Handover the users benefit from up to 31% energy savings with insignificant degradation in quality, in comparison with other energy efficient solutions.  ...  In this context we propose Adapt-or-Handover, a hybrid multimedia delivery solution, which balances the benefits of multimedia content adaptation and of network selection in order to decrease power consumption  ...  The authors of [28] [29] propose the use of a proxy server that performs on-the-fly transcoding and dynamic adaptation of the video content (brightness compensation) based on the feedback from the  ...
