Abstract	Motion Capture (MoCap) technology is becoming increasingly popular in gaming, entertainment, and multimedia industries. Interactive systems usingMoCap technology require low-delay MoCap data compression. In this paper, we extend previous work on low-delay MoCap compression by introducing several useful features, such as unrestricted quantization, more efficient entropy coding, as well as encoder rate control. Experimental results show that the proposed rate control provides better than 99% accuracy in controlling encoder's output bitrate. At the same time, improvements in quantization and entropy coding provide over 20% reduction in bit rate for the same reconstruction quality, compared to the current state of the art.
