Abstract: Techniques are provided herein for receiving at a video processing device color video frames comprising grayscale components and color components. The grayscale components corresponding to each of the color video frames are extracted as each of the color video frames is received to obtain grayscale video frames. The grayscale video frames are transmitted at a first transmission rate. Color components for selected color video frames are periodically fused with selected grayscale video frames to obtain fused color video frames, and the fused color video frames are transmitted at a second transmission rate interspersed with the grayscale video frames transmitted at the first transmission rate.
