Abstract (en)
[origin: WO9953633A1] Transceiver system including a transmitter and receiver. The transmitter transmits radiation having a varying operating frequency. It is preferred that the radiation be visible light. The operating frequency is varied in a way that eliminates visible flicker. A receiver receives the encoded radiation, decodes the coded data, and delivers the decoded data signal to an output stage. The output may be audio information, textural information or graphical information. A two level coding scheme is preferred.
