Abstract: | The evolution of mobile network and the popularization of mobile devices; the demand for multimedia services and 3D graphics
applications on limited resource devices is more contemporary. Most of the works on multimedia transmission are focused on
bit errors and packet losses due to the fading channel environment of a wireless network. Error resilient multimedia is significant
research topic which can be adapted to the different conditions in a wireless environment. The current solutions in transmission
of multimedia across different networks include some type of transcoder where the source is partially or fully decoded, and
re-encoded to suit the network conditions. This paper introduces a flexible progressive coding framework for 3D meshes, which
can be adapted to the different conditions imposed by wired and wireless channels at the bitstream level. By avoiding the
computationally complex steps of transcoding between networks, could deteriorate decoded model quality. The framework also
allows refined degradation of model quality when the network conditions are poor due to congestion or deep fades.
