Abstract :
We introduce the idea of distortion side information, which does not directly depend on the source but instead affects the distortion measure. Such side information is not only useful at the encoder, but under many conditions of interest, knowing it at the encoder alone is sufficient and knowing it at the decoder alone is useless.
