Abstract :
A wavelet-based videophone scheme proposed, where the video bits are unequal error protection (UEP) using irregular convolutional codes (IRCCs). The proposed system uses adaptive arithmetic coding (AAC) for encoding the motion vectors and individual wavelet subband coefficients. The turbo-equalized IRCC-aided videophone scheme is capable of attaining a near unimpaired video quality for channel signal-to-noise ratios (SNRs) in excess of about 4.5 dB over a five-path dispersive AWGN channel
