Abstract

We have designed and implemented a compact and simple network oriented device, a NetSpeaker, which mainly consists of a DA converter, an amplifier and buffers, in order to enable setting many terminals and realize ubiquitous computing environment. It receives WAV formatted data via IP packets and simply plays it by DA converting. All the sound outputs of Windows XP/2000 applications can be played on remote NetSpeakers, since we implemented the sound forwarding function as a virtual sound device, which generates WAV data of sound outputs of applications and sends them to a selected NetSpeaker. In this paper, we show design of this NetSpeaker system and its application in a service mobility environment.
