ESTIMATOR FOR ESTIMATING A PROBABILITY DISTRIBUTION OF A QUANTIZATION INDEX |
摘要 |
Estimator for estimating a probability distribution of a quantization index The invention relates to an estimator (1007) for estimating a probability distribution of a quantization index generated from a source coder encoding a source signal, into a sequence of quantization indices, the source signal being described by a signal model, the source coder providing a current quantization index and current side information, the estimator being configured to obtain auxiliary parameters based on a configuration of the source coder and the current available side information and the signal model, the estimator being further configured to adaptively update the probability distribution of a quantization index upon the basis of a probability density function relating to a previous state of the estimator, the auxiliary parameters, the current quantization index and the current side information. |
