Motion adaptive intra refresh for MPEG-4
Stewart Worrall, Abdul Hamid Sadka, Ahmet M. KONDOZ, P. F. Sweeney · Electronics Letters · 2000
The sensitivity to error of a video bitstream often changes as the amount of motion within a scene changes. Taking this into account, a scheme that attempts to optimise error robustness by varying the amount of adaptive intra refresh blocks is presented. Simulation results demonstrate the benefits of the proposed technique.
