    "abstract": "We consider the problem of the optimal compression rate in the case of the\nsource producing mixed signal states within the {\\it visible} scheme (where\nAlice, who is to compress the signal, can know the identities of the produced\nstates). We show that a simple strategy based on replacing the signal states\nwith their {\\it extensions} gives {\\it optimal} compression. As a result we\nobtain a considerable simplification of the formula for optimal compression\nrate within visible scheme.",
