This paper proposes a portable network video conferenc ing tool (Portable DVTS) using portable noteboook com puters(note PC) and IEEE1394 equipped DV Camera: real time high video/audio quality communication tool focused on a high speed network using note PCs. note PC has lim ited availability on processor and network interface speed due to its compact mobility aware system construction. Furthermore adaptive usage of power management features available on some interfaces are not implemented to DVTS and mother operating system. This research implements a characteristics of the unique note PC features to DVTS and its operating system. High quality video and audio communication system is implemented. Evaluation shows 125 minutes of continuous battery operation with battery life extension compared to 70 minutes with traditional sys tems. Collaboration with network device management en ables 100% packet transfer compared to 89% without any Resource adaptations.
