Product channel codes are proposed to protect progressively compressed
and packetized images for noisy channels.
Within packets, the product code uses the concatenation of a rate
compatible punctured convolutional code and an error detecting parity
check code. Across packets, Reed-Solomon codes are used. Benefits
include flexible choice of delay, adaptability of error protection
level (i.e., unequal error protection), and scalable decoding
complexity. The system outperforms the best known image coders for
memoryless channels and performs well on fading channels.
