QUALITÄTSVERBESSERUNG EINES AUDIOSIGNALS IN EINEM DIGITALEN NETZWERK

摘要

The invention relates to a network element (1) and a method for enhancing the quality of digitised analogue signals transmitted in parameterised coded form via a digital network. In order to enable an enhancement of the quality of the digitised analogue signals on network side, the network element comprises means (20, 21) for extracting signals from and insert signals into the network, first processing means (24) for processing the extracted parameters in the parameter domain with functions suitable to enhance the quality of the digitised analogue signals and second processing means (26) for processing the extracted parameters in the linear domain with functions suitable to enhance the quality of the digitised analogue signals. Moreover included analysing and selecting means (23, 27) determine the expected enhancement of quality in the different processing domains and cause a corresponding insertion of processed signals back into the network. The proposed method comprises corresponding steps.
