7. A multi-channel audio transmission system comprising: a first sender multi-channel encoder executing in one or more processors, wherein the first sender multi-channel encoder is configured to encode a plurality of surround audio channels to create a first pair of encoded channels, wherein the first pair of encoded channels have the first plurality of surround audio channels encoded therein; and a second multi-channel encoder executing on one or more processors, wherein the second multi-channel encoder is configured to encode the first pair of encoded channels with a plurality of different dialog channels to create a second pair of encoded channels, wherein the second pair of encoded channels have the first plurality of surround audio channels and the plurality of different dialog channels encoded therein.
