Abstract:
A method for allocating a channel to a selected output plug of a plurality of output plugs in a digital interface of a first digital device, wherein a predetermined relationship with a state value of a predetermined part of a second digital device is set in accordance with a specification of the digital interface which includes the output plugs, the method comprising the steps of:(a) calculating a channel number to be allocated to the selected output plug in accordance with predetermined conditions of the digital interface specification; (b) determining whether the channel number calculated in the step (a) can be allocated to the selected output plug; and (c) performing allocation of the channel number to the selected output plug if it is determined in the step (b) that the channel number can be allocated to the selected output plug according to the digital interface specification, and if it is determined in the step (b) that the channel number can not be allocated to the selected output plug according to the digital interface specification, determining an arbitrary channel number which is currently available for allocation, setting the state value of the predetermined part of the second digital device based on the arbitrary channel number in order to satisfy the conditions of the digital interface specification, and allocating the arbitrary channel number to the selected output plug according to the satisfied conditions of the digital interface specification.
