Abstract
A method for enhancing image quality of compressed video stream, mirrored thorough wireless network using a compression scheme, between a source device and a sink device. The method includes identifying idle time in the compression scheme of video, where the image change is below a predefined threshold for pre-defined period of time, calculating color code corrections between an original source last image and a decoded last image, sending corrections from the source device to the sink device in real-time during identified idle time and performing an image correction at the sink device based on the received correction.
