Abstract: A home health care system utilizing a community antenna television CATV system controls two-way communication between a doctor's terminal in a medical office and each of a plurality of subscriber's terminals with the aid of a multiple channel access MCA system line controller. The line controller selects an unused communication channel to connect monitoring television receiving television cameras, sender-receiver terminals, and data terminals at the doctor's terminal and a subscriber's terminal, so that the doctor can directly interrogate patients at home, and the patients can be automatically monitored at home using images and voice by the doctor in the medical office, without hindrance to normal CATV broadcasting.
