A real-time system for portable homecare applications

An ideal homecare system needs to process multiple diagnostic signals using a portable battery-driven device, and provide a real-time audio/video interface for telemedicine application. In this paper, we present a low cost real-time homecare system based on a commercial digital camera platform. In addition to the typical media recording functions of a digital camera, such as MPEG recording, the proposed system can further compress phonocardiogram (PCG) signal concurrently.
