ABSTRACT:
Movable and audible toys and other animated devices spaced apart from a television screen are provided with program synchronized audio and control data to interact with the program viewer in relationship to the television program. A sampling keyboard-based encoder for kinetic device actuating signals is coupled via an audio mixer to an audiovisual programming source and television transmitter carrying an audio based kinetic and audio signal complex. At a remote location, coded audio and kinetic device signals along with audiovisual programming is received and the audiovisual programming content is displayed for viewing and listening. Stereo soundband based program audio signals are decoded and separated from the stereo sound band based device audio and kinetic signals. The device audio and kinetic signals are retransmitted to a spaced apart toy causing the device to be audible and move in synchronization with the spaced apart audiovisual programming. A single band low powered FM transmitter carries the audio kinetic signal complex in proximity yet spaced apart from a receiver coupled to an audio cassette configured magnetic head transducer disposed in the kinetic device to communicate audio and kinetic information to a device speaker and motors to cause the device to move and be audible.
