Low-cost Real-time Video Streaming System Using Off-the-Shelf LEDs

VLC systems often requires costly devices and a lengthy design process due to its high performance and precision requirement. In this work, low-cost devices and rapid prototyping have been adopted to realise a system which can transmit real time video streaming. A VLC transmitter and receiver circuit has been designed and implemented. The full system consists of a mechanical enclosure, which was fabricated using rapid prototyping techniques such as 3D printing and laser cutting, electrical circuitry system and the optical modules. The prototype was thus able to transmit video signals compatible with the National Television System Committee (NTSC) standard, up to a distance of 3.1 m.
