Abstract

This work focus on the problem linked to the transmission of real time video over packet wireless network.Our objective is to define mechanism able to insuring a quality of video in spite to the problems of packet losses and transmission delays characterizing this type of network.The proposed mechanism is based Forward Error Correction (FEC) compatible with the H.264/AVC standard.This mechanism relies on a ratedistortion algorithm controlling the channel rates under a global rate constraint given by the network.This optimization takes into account the type of packet and his length; the tool of data portioning is used in our proposition.This mechanism leading to an unequal error protection of different units of coded sequence.A Reed-Solomon channel coding in application layer is adapted to unequal protected data.The experimentation results indicate the efficiency of our proposition compared to the equal error protection.
