Error-Resilient Image and Video Transmission
Over the Internet Using Unequal Error Protection

Abstract--This paper presents a new bit-plane-wise unequal
error protection algorithm for progressive bitstreams transmitted
over lossy networks. The proposed algorithm protects a com-
pressed embedded bitstream generated by a 3-D SPIHT algorithm
by assigning an unequal amount of forward error correction
(FEC) to each bit-plane. The proposed algorithm reduces the
amount of side information needed to send the size of each code to
the decoder by limiting the number of quality levels to the number
of bit-planes to be sent while providing a graceful degradation
of picture quality as packet losses increase. We also apply our
proposed algorithm to transmission of JPEG 2000 coded images
over the Internet. To get additional error-resilience at high packet
loss rates, we extend our algorithm to multiple-substream unequal
error protection. Simulation results show that the proposed
algorithm is simple, fast and robust in hostile network conditions
and, therefore, can provide reasonable picture quality for video
