The traditional entropy is an efficient method for high-level power estimation
but it doesn’t work when the input signals are temporal correlated
as is always the case for video and audio streams.This paper aims at this problem.We put forward a new definition of entropy.With the help of the conditional transition probabilities
the proposed algorithm can bring us the estimations with adequate accuracy for temporal correlated inputs.The theoretical proofs and the BENCHMARK experimental results verify the efficiency of our algorithm.
