Abstract
A system and method for managing encoded information in a real-time screen-to-camera communication environment are disclosed. The system converts information into a pre-defined number of characters and generates data symbols in shapes and pilot symbols corresponding to the characters. Further, the system embeds the data symbols in media content frames and modulates pixels and boundaries for display of display device, based on luminance, and adaptively displays frames as temporal-complementary frames. Furthermore, the system detects frames from recorded content, extracts data symbols based on grid and fixed pattern, and detects bit values by analyzing color differences. Additionally, the system generates information based on the detected bit values and outputs the information on an user device display, including products, recommendations, services, and relevant information related to the media content.
