Abstract :
In this paper, we proposed a method to decrease the effects of data loss in communication of a video sequence using phase scrambling. Phase scrambling is used to spread the data of each pixel of a video sequence over all pixels of the scrambled video. In our experiments we studied the effects of different loss patterns. The results obtained by employing this method shows great improvements compared to cases of data loss without exploiting phase scrambling. This technique can be readily used in transmission of video segments over unreliable networks.
