Robust Transmission of H.264/AVC Video Signals

useful to improve the error resilience of an H.264/AVC compressed
video signal. In fact, network failures usually involve significant
quality degradation due to the temporal and spatial prediction.
Solutions to this problem can be introduced both at the encoder and
decoder side of the channel.
First, a brief review of the H.264/AVC standard will be provided,
focusing on the Network Abstraction Layer and error resilience tools
supported by the standard. Two different error concealment algorithms
will be shown to face with the frame and slice loss case respectively.
Working at the encoder side, redundant slices can be considered as a
simple and effective tool to retransmit important portions of the
video signal. Starting from distributed video coding ideas, a
Systematic Lossy Error Protection scheme will be reported. This scheme
exploits coarsely quantized redundant slices together with channel
coding to provide a generalization of traditional FEC schemes.
Finally, future works on the streaming of scalable video content over
peer-to-peer networks will be reported.
