CATV system provided with a digital broadcasting receiving unit and a bilateral remote controller

A remote control transmitter is so constructed that when a group menu representing a combination of individual functions is selected by operation of an operating part, a controller effects display of the individual functions of the group menu in parallel with the group menu. Since the correspondence between an overview of the plurality of group menus and the individual functions of the specified group menu is easy to understand, the remote control transmitter obtained allows easy setting of the function.
