Abstract (en)

[origin: WO2019192705A1] Abstract Method for post-processing of a transcoded digital signal including audio and/or video data to get an enhanced transcoded digital signal, whereby said transcoded signal was obtained by decoding of an encoded signal using a decoder and said encoded signal was obtained by encoding of a source signal using an encoder, whereby the method comprising the following steps using a postprocessor: providing a plurality of transcoded signal frames, whereby said transcoded signal frames were generated by separating one of said transcoded digital signal processing each transcoded signal frame into a first representation within a processing domain; feeding each first representation of the transcoded signal frames into an artificial neural network to obtain for each first representation a second representation of the respective transcoded signal frame, whereby said artificial neural network is provided such that the artificial neural network is trained a mapping from a representation of a transcoded signal frame within said processing domain to a repre- sentation of a source signal frame within said processing domain; generating an enhanced transcoded digital signal based on the second represen- tations obtained from the artificial neural network; and outputting said enhanced transcoded digital signal.
