Advanced Communication Technology, The 9th International Conference（2007）
摘要
This paper describes the design and implementations of the application service based on embedded Linux; personal voice recorder (PVR) which uses WiBro network for data communications and CDMA network for voice communications. PVR consists of client and server. PVR client send CDMA voice data to PVR server located in the Internet through WiBro network. Then, PVR server converts voice data to wave form and stores it. In case of shortage of storage space on terminal, PVR makes user to store voice data.
