Abstract
Official abstract text for this publication.
Methods which uses interpolated primitive matrices to decode encoded audio to recover (losslessly) content of a multichannel audio program and/or to recover at least one downmix of such content, and encoding methods for generating such encoded audio. In some embodiments, a decoder performs interpolation on a set of seed primitive matrices to determine interpolated matrices for use in rendering channels of the program. Other aspects are a system or device configured to implement any embodiment of the method.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for encoding an N-channel audio program, wherein the program is specified over a time interval, the time interval includes a subinterval from a time t1 to a time t2, and a time-varying mix, A(t), of N encoded signal channels to M output channels has been specified over the time interval, where M is less than or equal to N, said method including steps of: determining a first cascade of N×N primitive matrices which, when applied to samples of the N…
