An interactive system using digital broadcasting and Quick Response code

This paper presents a novel method of creating synchronized interactive TV applications using Quick Response (QR) code, where QR code is used to tag the broadcasted TV content. The QR code is decoded at the receiver side to communicate with an Internet server for interactivity. The proposed technique can be used for both classical analog TV and digital TV. The method described here can also be applied on presently growing mobile TV and Over-the-Top (OTT) TV. It assumes Internet connectivity on the client. We present interactive TV based distance education as an example of a synchronized application using this system.
