The present invention relates to providing a television program specially prepared for the application to be interactive with the viewer. The source of the television program may vary, for example, it may be broadcasted material, VCR playback or a DVD playback. The program is enhanced with an inaudible high frequency embedded in the audio portion of the program. The signal, via a high frequency decoder and microprocessor is being transmitted by an infra red transmitter. Upon being received by the viewer with an infra red receiver, the signal is being processed and either displayed on a LCD display or made audible by a sound processor.
A mobile object, such as a hollow ball containing an electronic circuitry system is proposed. The circuitry includes a speech processor and a controller, an integrated circuit for a speech recorder, an integrated circuit for an audio amplifier, a microphone and a power supply and an impact switch and push button switches. In response to impact, the circuitry generates a randomly chosen multiple choice questions. According to the answer chosen by the player, he/she presses a push button switch representing the answer. The electronic system then verifies whether the answer is correct or incorrect and generates a signal accordingly.
