Inventors include Pfaff, Jonathan; Kirchhoffer, Heiner; Helmrich, Christian; Pientka, Sophie; Rudat, Christian; Schwarz, Heiko; Marpe, Detlev; and Wiegand, Thomas.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: A decoder for decoding a digital time-varying signal from a data stream is presented. The decoder is configured to decode the digital time-varying signal from the data stream in non- overlapping temporal blocks by decoding each of transform-coded temporal blocks of the non-overlapping temporal blocks of the digital time-varying signal by predicting the respective transform-coded temporal block using a selected prediction mode out of a set of prediction modes to obtain a prediction signal, decoding coefficients from the data stream, the coefficients representing a prediction residual signal of the respective transform-coded temporal block in a transform domain, subjecting the coefficients to a predetermined re-transformation from the transform domain to time domain to obtain a time-domain prediction residual signal representing a prediction residual signal of the respective transform-coded temporal block in a time domain, and correcting the prediction signal using the time-domain prediction residual signal, wherein the predetermined re-transformation is a non-overlapping transform.
