ERROR-RESILIENT VIDEO CODING USING MULTIPLE REFERENCE FRAMES

Abstract

An error-resilient scheme based on multiple reference frames is proposed, which employs error-resilient frames (ER-frame) as part of reference frames and adopts a rate-distortion optimized (RDO) technique to choose the blocks referring to ER-frames. To reduce the computational cost, two techniques are further proposed. Experimental results show that adopting ER-frames enhances error-resilient performance; using RDO makes the scheme adaptive to various packet loss rates and video sequences; and applying time reduction techniques reduces computational cost significantly with neglectable performance loss.
