Video-transmission of image in disturbed medium

We simulated on Matlab a video-transmission of image without and with coding. A transitory interruption of the transmission results in the disappearance of the signal on several lines leading to an irremediable loss of information in the first case.
If one applies the chaotic transformation to the video
signal of the image before emission, the loss of information
is distributed on all the surface of the image during the reconstitution.
disturbed coded image
By varying the step of the transformation for each image, one can still minimize the noise disturbing the transmission.
