ABSTRACT
This paper presents a coordinated multiple-substream unequal er-
ror protection and error concealment algorithm for SPIHT-coded
bitstreams transmitted over lossy channels. In the proposed
scheme, we divide the video sequence corresponding to a group
of pictures into two sub-sequences in the temporal domain and
independently encode each sub-sequence with a 3-D SPIHT algo-
rithm to generate two independent substreams. Each substream
is protected by an FEC-based unequal error protection algorithm
that assigns unequal forward error correction codes for each sub-
stream with bit-plane granularity. The information that is lost dur-
ing transmission for one substream is estimated at the receiver by
using the correlation between the two substreams and the smooth-
