Key result
Low-cost digital camera platform processes and compresses real-time phonocardiogram signals during multimedia recording.
Why the study?
An ideal homecare system requires processing multiple diagnostic signals with a portable battery-driven device and real-time audio/video telemedicine interface.
A low-cost real-time homecare system based on a digital camera platform can process and compress phonocardiogram signals for telemedicine applications.
Offers low-cost real-time PCG processing for home telemedicine; leaves open clinical validation before practice adoption.
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 applications. In this paper, we present a low cost real-time homecare system based on a commercial digital camera platform. In addition to the typical multimedia recording functions of a digital camera, such as JPEG and MPEG-1/MPEG-4 recording, the proposed system can further process and compress phonocardiogram (PCG) signal concurrently.
