MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202648069789 A) filed by Dolby Laboratories Licensing Corporation on June 03, 2026, for Quantization And Entropy Coding Of Parameters For A Low Latency Audio Codec.
Inventors include Mcgrath, David S.; Tyagi, Rishabh; Brown, Stefanie; and Torres, Juan Felix.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: ABSTRACT QUANTIZATION AND ENTROPY CODING OF PARAMETERS FOR A LOW LATENCY AUDIO CODEC Described is a method of frame-wise encoding metadata for an input signal, the metadata comprising a plurality of 5 at least partially interrelated parameters calculable from the input signal. The method comprises, for each frame: iteratively performing, by using a looping process, steps of: determining a processing strategy from a plurality of processing strategies for calculating and quantizing the parameters; calculating and quantizing the parameters based on the 10 determined processing strategy to obtain quantized parameters; and encoding the quantized parameters. In particular, each of the plurality of processing strategies comprises a respective first indication indicative of an ordering related to the calculation and quantization of individual parameters; and the processing strategy is determined based on at least one bitrate threshold.
