Slice Sorting for Unequal Loss Protection of Video Streams
Enrico Baccaglini, Tammam Tillo, Gabriella Olmo · IEEE Signal Processing Letters · 2008
In this letter, we propose a novel unequal loss protection scheme, which allocates FEC codes to video slices according to their impact on the GOP distortion. This is evaluated taking the concealment procedure and the drift effect into account. Simulation results show that the proposed algorithm outperforms state-of-the-art approaches, reducing the gap with the error-free performance curve. Moreover, the complexity of the additional stage required to pilot the protection allocation stage is negligible with respect to traditional ULP schemes.
