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.

Abstract: A machine learning based system and method for controlling residual artifacts in media contents to optimize user experience in real-time screen-to-camera communication environment, is disclosed. The machine learning based method includes converting RGB values of pixels to values of orthogonal or perceptual color space values for pixels; segmenting intensities of frames associated with the media contents, into bright, dark, and middle regions; generating symbols comprising optimized-frequency regions using a machine learning model; setting width border of boundaries to pre-determined pixel values for encoding ACR data; dividing the boundaries into boxes to embed information associated with symbols; assigning a bit value of one to boxes comprising first pre-determined sizes, and a bit value of zero to the boxes comprising second pre-determined sizes; assembling boxes within interior of frames; and controlling the residual artifacts of an encoding process in the media contents by reducing modulation depth based on the optimized redundancy.

Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.
