PROBLEM TO BE SOLVED: To provide a multicast distribution system, a client device, an upper router controller, a method of displaying content and a computer program that can display channel switching time of the content in a discriminating state.

SOLUTION: A multicast distribution system includes a distribution server for multicast distributing a content via at least one upper router and a plurality of lower routers, a plurality of client devices for reproducing the content multicast distribution by the distribution server and an upper router controller for controlling the upper router. Each client device adds information representing channel switching time of each content on the basis of reservation schedule information reported from the upper router controller and displays the channel switching time of the content in a discriminating state on the basis of the information indicating the channel switching time.
