Abstract-- This paper presents a distributed video streaming
framework using unbalanced multiple description coding (MDC)
and forward error correction. In the proposed video streaming
framework, two senders simultaneously stream complementary
descriptions to the receiver over different paths. To minimize the
overall distortion and exploit the benefits of multi-path transport
when the characteristics of each path are different, an unbalanced
MDC method for wavelet-based coders combined with a TCP-
friendly rate allocation algorithm is proposed. The proposed
rate allocation algorithm adjusts the transmission rates and the
channel coding rates for all senders in a coordinated fashion to
minimize the overall distortion. Simulation results show that the
proposed unbalanced MDC combined with our rate allocation
algorithm achieves about 1 - 3 dB higher PSNR compared to
