摘要： A method for mapping a plurality of input channels of an input channel configuration to output channels of an output channel configuration comprises providing a set of rules associated with each input channel of the plurality of input channels, wherein the rules define different mappings between the associated input channel and a set of output channels. For each input channel of the plurality of input channels, a rule associated with the input channel is accessed, determination is made whether the set of output channels defined in the accessed rule is present in the output channel configuration, and the accessed rule is selected if the set of output channels defined in the accessed rule is present in the output channel configuration. The input channels are mapped to the output channels according to the selected rule.
