Integrating virtual human animation in networked virtual environments (NVEs) has the potential to create severe network load issues. In NVEs, users are represented by their virtual embodiments. The articulated structure of these embodiments introduces a new complexity in the communication, representation and streaming of animations. This might create a significant overhead, especially as the number of participants in the simulation increases. In this paper, we present problems and solutions to efficiently transmit virtual human data over the network.
