We briefly formulate fundamental notions and results of Shannon theory on reliable transmission via coding and give a survey of
results obtained in last two-three decades by the authors, their colleagues and some other researchers. The paper is written with the
goal to make accessible to a broader circle of readers the theory of
rate-reliability. We regard this concept useful to promote the noted
problem solution in parallel with elaboration of the notion of reliabilityreliability dependence relative to the statistical hypothesis testing and
