Error and Congestion Resilient Video Streaming over Broadband Wireless

Laith Al-Jobouri, Ismail Ali, Martin Fleury, Mohammed Ghanbari
2015 Computers  
A packetization strategy is an effective tool to control error rates and, in the paper, source-coded data partitioning serves to allocate smaller packets to more important compressed video data.  ...  The scheme for doing this is applied to real-time streaming across a broadband wireless link.
