| Abstract |
This research is motivated by the needs of robust streaming of
vector graphics contents over the Internet, wireless and other
lossy networks. We present a multiple description coding
(MDC) technique for error resilient compression and transmission
of 2D vector graphics contents. An object is coded
into two or more so-called co-descriptors, which are transmitted
in separate data packets and generally via different network
routes from a server to a client. Each co-descriptor can
autonomously provide an approximation of the input object,
and it can collaborate with other co-descriptors, if also available
at the decoder, to refine the approximation. |
