Frame Concealment for H.264/AVC Decoders

The H.264/AVC offers a high video coding efficiency and is the first standard that provides an explicit support for the transmission of multimedia content over apacked switched network, specifying a Network Abstraction Layer (NAL). If we consider the transmission of a low resolution video sequence over a wireless LAN network or a UMTS link, we can usually observe that a coded picture typically fits the packet size, therefore a transmission error produces the loss of a whole frame. In this paper we propose a novel technique to perform the concealment of a whole frame for H.264/AVC video decoders.
