Abstract:
Packet switched video telephony over wireless networks for
hand-held devices requires low-delay, low-complexity error
control mechanisms to deal with packet loss. We present an
efficient solution for 3G networks based on LT coding, reference
picture selection, and cross-layer optimization. Experimental
results on a 3G network simulator for H.264
compressed standard video sequences show that our method
achieves significant peak-signal-to-noise ratio and percentage
degraded video duration improvements over a state of
the art technique.
