Personal health care services through digital television.

Personal health care has obtained increasing importance in the field of health care as the populations' age in the industrialised countries and resources available for health care remain limited. Personal health care through digital television is an exiting possibility in the realisation of new types of services answering to this demand for increased personal action and responsibility in health care. The possibilities of digital television in health care are studied in the Health Care Television (HCTV) research project of the Digital Media Institute at Tampere University of Technology. In this paper personal health care services are studied mainly from the perspective of the interactive service infrastructure of digital television. Firstly we present the general infrastructure of digital television and the different interactive service types of digital television. The usage of these service types in personal health care applications is also discussed. Finally, a web-based application based on chronic atrial fibrillation and its test use is presented. The application is used as a research platform for personal health care applications in digital television.
