ABSTRACT:
A one-way individual or group addressable communication link by paging system protocol delivers to a small data terminal of an entertainment or education device command messages relevant to current real world information such as news or weather information, and also relevant to current television series storylines. The device provides a separate and independent mechanism augmenting educational or entertainment aspects of current events or television programming without requiring an expensive user interface mechanism in implementation of complex and robust control and configuration features.
