An efficient error protection scheme is proposed for video delivery over lossy channels. Flexible Macroblock Ordering is used to generate spatial descriptions that are sent over disjoint paths. Additionally, descriptions are partitioned to allow unequal error protection against burst errors. Experimental results show that a significant quality gain can be achieved (up to 3 dB) in the presence of burst...
The need to respond to congestion and channel loss over not one but two wireless links is an impediment to video streaming between one mobile user device and another via an intervening IP network. The result can be poor wireless channel utilization and interruptions to the streaming process. This paper proposes that multi-connection streaming will avoid the need for application-specific cross-layer...
This paper demonstrates that growth codes, based on Raptor channel coding, allow incremental protection of H.264 video codec data-partitioned network adaption layer units. When combined with increased protection of video reference frames, in an ADSL erasure channel up to 10 dB in video quality (PSNR) can be gained through this scheme compared to equal error protection with rateless codes. Equivalent...
All-IP network delivery of video is a promising application of congestion control. This paper compares the advantage of a fuzzy logic controller over existing controllers for this type of network. The acceptance of fuzzy logic for video control has gained ground but its advantages will become even more apparent through interval type-2 (IT2) logic rather than traditional type-1 logic. This paper demonstrates...
