Li-Fi BASED REAL TIME VIDEO TRANSMISSON FOR PATIENT MONITORING SYSTEM

摘要

The aim of this work is to achieve live surveillance of the patient using LI-FI(light fidelity).Li-fi is an advanced and promising technology can be used in many medical applications.In this paper,a prototype of live video broadcast using LEDs is proposed.The prototype presented transfers the data with single LED,and is capable of illumination as well as data broadcast.Whole process is kick started by converting analog signal into digital form in transmitter section.LM359 IC amplifies video signal with two inverting amplifiers which possess high gain bandwidth and allows high frequencies and it is coupled to LED which accelerates the transmission process and it's geared at high speed by receiving the high frequency video signal in digital form by a photo detector.The output from the receiver circuit is analog output given to television module using a RCA cable.
