A Perceptual-Based Video Coder for Error Resilience

(PREVIOUS TITLE: LAYERED VIDEO CODING USING PERCEPTUAL CODING CRITERIA FOR ERROR RESILIENCE IN PACKET NETWORKS) Transmission of video over lossy packet networks is very much a challenging open problem. Heuristic approaches have been used to deal with the loss of coding blocks, and with the propagation of these errors due to prediction loops in video coders. This paper applies spatio-temporal perceptual criteria to improve these approaches by reducing the additional information needed to deal with packet loss.
