Summary:The problem of error control and concealment in video
communication is becoming increasingly important because of the growing
interest in video delivery over unreliable channels such as wireless
networks and the Internet. This paper reviews the techniques that have
been developed for error control and concealment. These techniques are
described in three categories according to the roles that the encoder
and decoder play in the underlying approaches. Forward error concealment
includes methods that add redundancy at the source end to enhance error
resilience of the coded bit streams. Error concealment by postprocessing
refers to operations at the decoder to recover the damaged areas based
on characteristics of image and video signals. Last, interactive error
concealment covers techniques that are dependent on a dialogue between
the source and destination. Both current research activities and
practice in international standards are covered
