In this work we discuss different architectures for error resilient video streaming. The architectures exploit a resilient video coding scheme, based on out-of-band transmission of suitable redundant information, that counteracts synchronization loss between the decoder and the bit-stream due to transmission errors. We investigate unicast and multicast video streaming solutions and show a power/bandwidth efficient hybrid unicast/multicast acrchitecture. Experimental results show the decoded video quality obtained by adopting the resilient streaming architecture in the case of H.264 coding.
