Abstract
Wireless communication protocol for enabling unidirectional communications in a simplex environment, or bidirectional communications in a duplex environment, between a controller and one or more controlled devices. The controller transmits video data and control data that may include voice synthesis coefficients and motor movement coefficients for processing by the controlled devices. The video data drives a display device to depict a scene, and the control data drives the controlled devices so that the controlled devices behave as characters in the scene depicted on the display device. Each controlled device is operable for recognizing messages directed to the device and for parsing these messages into control signals for a number of end effectors, such as speech synthesizers, servo motors, lights, heat sources, pumps, etc. The content of messages for, and the set of end effectors in, any particular controlled device may be changed so that the system is forwardly compatible for new controlled devices using the protocol.
