Lei Huang, Uwe Horn, Frank Hartung, Markus Kampmann
2002 Proceedings of the 5th ACM international workshop on Wireless mobile multimedia - WOWMOM '02

Implications of Smoothing on Statistical Multiplexing of H.264/AVC and SVC Video Streams

G. Van der Auwera, M. Reisslein
2009 IEEE transactions on broadcasting  
We similarly identify the buffer sizes for the buffered multiplexing of unsmoothed H.264 SVC, H.264/AVC, and MPEG-4 Part 2 streams that give close to optimal performance.  ...  The higher traffic variability of the SVC encoder can lead to smaller numbers of streams supported with bufferless statistical multiplexing than with the H.264/AVC encoder (and even less streams than with  ...  David for developing the automated scheduler of the encoding jobs.  ...

2007 International Conference on Networking and Services (ICNS '07)  
We show that HTTP enhanced with network flow buffering performs well, especially under high packet loss and highly variable bandwidth conditions, when compared with using either straight HTTP or streaming  ...  Network flow buffering is the use of a simple remote flowregulating buffer that is dynamically deployed between a Web client and server to improve the performance of HTTP-based access and playback of video  ...  The extra buffering that occurs when there is no smoothing is required because the player's buffer is suffering from underflow, as the average bandwidth is lower than the video bit rate.  ...
