ABSTRACT
This paper presents a TCP-friendly rate allocation algorithm for
multiple description coding combined with path diversity. A 3-
D SPIHT-based multiple description coding is used to generate
two independent substreams and each substream is protected with
an FEC-based unequal error protection algorithm. In the pro-
posed video streaming framework, two senders simultaneously
stream complementary substreams to the receiver over different
paths. The proposed rate allocation algorithm coordinates dis-
tributed video streaming from multiple senders to a single receiver
to minimize the overall distortion. Simulation results show that
the proposed algorithm increases tolerance to packet loss due to
network congestion and achieves higher visual quality compared
to non-adaptive methods.
