Abstract (en)
[origin: WO8401873A1] A system for transmitting information from a remote location (10) to a second location (24) and from the second location via a cable television network (26) to the cable subscribers. The system includes an alarm feature (34) to advise the cable television network subscribers that information is being transmitted even if their television units are not on. The system includes a first data processor (10), which is adapted to receive data from a variety of sources (12, 14, 16) and a plurality of second data processors (22a, 22i). Each of the second data processors (22) is connected to the head end (26) of one local cable television network (26). Information from the first data processor (10) is transmitted to the proper second data processor (22) and thereafter transmitted via the cable (28) to the individual cable television subscribers to display information on their television receivers (30). The system actuates an audible alarm (44) at the television receiver, even if the television is turned off, to indicate that information is being transmitted.
