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 24):
A method for presenting audio content comprising a plurality of input channels to a system comprising a plurality of output channels different from the input channels, the method comprising:\n providing the audio content and a downmix matrix for mapping the input channels to the output channels, encoding the audio content; encoding the downmix matrix in accordance with  claim 15 ; transmitting the encoded audio content and the encoded downmix matrix to the system; decoding the audio content; decoding downmix matrix in accordance with  claim 1 ; and mapping the input channels of the audio content to the output channels of the system using the decoded downmix matrix, wherein the downmix matrix is encoded/decoded in accordance with the method of one of the preceding claims.
