The aim of this home telecare system is to combine biom?dical data, including three-channel electrocardiogram (ECG) and blood pressure (BP), video, and audio into a National Television Standard Committee (NTSC) channel for communication between the patient and healthcare provider. Digitized biom?dical data and output from medical devices can be further modulated to a second audio program (SAP) subchannel which can be used for second-language audio in NTSC television signals. For long-distance transmission, we translate the digital biom?dical data into the frequency domain using frequency shift key (FSK) technology and insert this signal into an SAP band. The whole system has been implemented and tested. The results obtained using this system clearly demonstrated that real-time video, audio, and biom?dical data transmission are very clear with a carrier-to-noise ratio up to 43 dB. ? 2000 IEEE.CATV; Home telecare; Telemedicine[SDGs]SDG3article; blood pressure; chronic disease; classification; disabled person; doctor patient relation; electrocardiography; feasibility study; home care; human; instrumentation; interpersonal communication; methodology; organization and management; signal processing; system analysis; Taiwan; teleconsultation; telemedicine; television; Blood Pressure; Chronic Disease; Communication; Disabled Persons; Electrocardiography; Feasibility Studies; Home Care Services; Humans; Physician-Patient Relations; Remote Consultation; Signal Processing, Computer-Assisted; Systems Integration; Taiwan; Telemedicine; Television; Bandwidth; Biomedical engineering; Blood; Electrocardiography; Fiber optic networks; Frequency shift keying; Health care; Information technology; Pressure; Signal to noise ratio; Television broadcasting; Television transmission; Blood pressure; Home telecare; Second audio program subchannel; Telemedicine; Cable television systemsjournal article10.1109/4233.826857https://doi.org/10.1109/4233.826857
