MUMBAI, India, Sept. 7 -- Intellectual Property India has published a patent application (202617085805 A) filed by Dolby International Ab on July 13, 2026, for Efficient Signalling Of Sub-Band Prediction Parameters.
Inventor includes Mundt, Harald.
The application for the patent was published on September 04, 2026, under issue no. 36/2026.
Abstract: Systems and methods for sub-band audio coding are disclosed. One example provides a method for coding input audio signals in a bitstream from a first device to a second device. The method includes, with the first device, obtaining a representation of the input audio signal in sub- bands, dividing a current frame into a current subset of the sub-bands that excludes other sub-bands, and determining a prediction parameter for the current subset of sub-bands. The method also includes, with the first device, determining an active/passive flag for at least one of the sub-bands and encoding the bitstream with the current subset of the sub-bands, a number of subsets, the prediction parameter for the current subset of sub-bands, and the active/passive flag for the other subsets of sub-bands. The method may include, with the second device, decoding the bitstream.
