Abstract
A router stores a value that indicates the maximum number of channels that can be output to a group, and the number of channels that are output to the group. When a member of the group indicates a channel change selection from a first channel to a second channel, the router drops the first channel before outputting the second channel when the maximum number of channels and the number of channels are equal.
