Effects of priority retries of I- and P-packets on average Y-PSNR variations of different scheduler designs under various congestion levels, with loose and tight real-time cuts (RT-Cut-400 ms and RT-Cut-200 ms, respectively): a SCS-CR with RT-Cut-400 ms, b SCS-CR with RT-Cut-200 ms, c PWD with RT-Cut-400 ms, d PWD with RT-Cut-200 ms, e VQD with RT-Cut-400 ms, and f VQD with RT-Cut-200 ms
