Abstract

Multimedia applications often suffer from packet losses in IP networks. In order to get a reasonable degree of quality when there is packet loss, it is necessary to have loss concealment mechanisms at the decoder. Video loss concealment is a range of techniques to mask the effects of packet loss in video communications.
