The quality of real-time video streaming over wireless links is significantly reduced due to packet losses and delays caused by rapid changes of the link conditions. We resolve this problem by two solutions. First, we have developed a responsive MAC adaptation method using SNR and packet loss statistics. The second solution depends on the first one; it allows the MAC to communicate information about changes of link conditions to the video codec. Together, these solutions prevent packet losses… CONTINUE READING
