Video Coding with Wavelet-Domain Conditional Replenishment and Unequal Error Protection

A simple and computationally lightweight video coder employing shape-adaptive, embedded intraframe coding and wavelet-domain conditional replenishment is proposed. Robustness to packet losses arises from packetization of the embedded bitstream with unequal error protection which is assigned to the packets with a fast, locally optimal procedure. Experimental results reveal that, when compared to H.264/AVC configured for low-complexity, error-resilient operation, not only does the proposed coder usually produce substantially superior rate-distortion performance as packet losses increase, it also achieves a significantly faster encoding speed.
