In this paper, a technique for transmitting level of details motion sequences for virtual character animation is proposed. We have demonstrated that by using progressive level of details (LOD) scheme on the motion capture information, efficient LOD representation of the skeleton motion can be obtained. The proposed virtual character encoder is scalable in nature providing a form of flexibility for the bit-stream to be partially decodable at any bit rate within the bit rate range to address the dynamic bandwidth constraint of a heterogeneous wireless network. Based on the structural characteristic of the virtual character, the packet will be delivered across dynamic channel condition to provide the viewer with the best reconstructed virtual character's motion quality.
