Abstract:
A method is described which decodes a downmix matrix for mapping a plurality of input channels of audio content to a plurality of output channels, the input and output channels being associated with respective speakers at predetermined positions relative to a listener position, wherein the downmix matrix is encoded by exploiting the symmetry of speaker pairs of the plurality of input channels and the symmetry of speaker pairs of the plurality of output channels. Encoded information representing the encoded downmix matrix is received and decoded for obtaining the decoded downmix matrix.

Claim (Index 14):
The method of  claim 1 , comprising decoding a compact matrix in which input channels in the downmix matrix associated with symmetric speaker pairs and output channels in the downmix matrix associated with symmetric speaker pairs are grouped together into common columns or rows, wherein decoding the compact downmix matrix comprises:\n receiving the encoded significance values and the encoded mixing gains, decoding the significance values, generating the decoded compact downmix matrix, and decoding the mixing gains, assigning the decoded mixing gains to the corresponding significance values indicating that a gain is not zero, and ungrouping the input channels and the output channels grouped together for acquiring the decoded downmix matrix.
