Rate Adaptive Selective Segment Assignment for Reliable Wireless Video Transmission

Abstract EN

A reliable video communication system is proposed based on data partitioning feature of H.264/AVC, used to create a layered stream, and LT codes for erasure protection.

The proposed scheme termed rate adaptive selective segment assignment (RASSA) is an adaptive low-complexity solution to varying channel conditions.

The comparison of the results of the proposed scheme is also provided for slice-partitioned H.264/AVC data.

Simulation results show competitiveness of the proposed scheme compared to optimized unequal and equal error protection solutions.

The simulation results also demonstrate that a high visual quality video transmission can be maintained despite the adverse effect of varying channel conditions and the number of decoding failures can be reduced.
