Distribution of SDTV and HDTV using VLC Techniques for Domestic Applications

This paper presents a visible light communication system that enables flat-panel TVs to receive DVB terrestrial, cable and satellite digital content wirelessly. The benefits of VLC over Wi-Fi and power-line networking based solutions are discussed, and the physical requirements of the system are defined. The paper also discusses how the MPEG transport stream of a set-top-box can be re-encoded for transmission over a free-space optical channel using a novel PPM modulation scheme.
