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 15):
A method for encoding 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,\n wherein encoding the downmix matrix comprises exploiting the symmetry of speaker pairs of the plurality of input channels and the symmetry of speaker pairs of the plurality of output channels, wherein respective pairs of input and output channels in the downmix matrix comprise associated respective mixing gains for adapting a level by which a given input channel contributes to a given output channel, wherein respective significance values are assigned to pairs of symmetric speaker groups of the input channels and symmetric speaker groups of the output channels, the significance value indicating if a mixing gain for one or more of the input channels is zero or not, and wherein the method further comprises:\n encoding the significance values, and \n encoding the mixing gains.
