Figure 2-1 Invisible Data Embedded Display TX Schemes PHY System Diagram – The PHY designed with specific key features in consideration to have error free and effective display to camera communication in the real-time usage of end system. The design goals are, Unobtrusive to Screen Viewer Works on dynamic visual Scene Angle and Distance Free Communication Rx Distance Adaptive Communication by Screen with interactive Camera Asynchronous Communication Rx Frame Rate independent Transmission Multi-Display Model for Transmission To achieve the above described design goal, the PHY designed with Spread Spectrum coded with M-PSK, M-FSK, Hybrid-M-PSK-FSK, 2D-Codes. The use cases of the modulation scheme with or without of SS Modulation parameter are described in this section. The Table 2-1 describes the data rate supported with different modulation schemes.
