A communications system having centralized management and multiply-hierarchical addressing schemes is disclosed. The system may be used in connection with supplying video, audio and data such as weather-related text, graphics, and information to affiliated receivers in a network for broadcast or display. Receivers may be addressed singly or in groups and allowed to determine their own addresses from information keyed, directly or indirectly, to a receiver characteristic such as the unit serial number. Lists of commands denominated 'scripts' and transmitted to receivers are used for controlling the various modes or states of the receivers.
