Content-Aware ARQ for H.264 Streaming in UTRAN

In this paper we propose a new content-aware ARQ scheme for H.264 video streaming over UMTS wireless links. We propose a new scheme which assesses the importance of each packet using the FMO (Flexible Macro-block Ordering) tool, a novel error robustness tool of H.264 video encoding standard. Temporal values are then given to video packets in respect to their importance. Carried out simulations show good improvement in video quality of the proposed mechanism.
