Definitions

  • the present invention relates to a television receiver, and also to an electrical installation including a television receiver.
  • a television receiver comprising circuitry to receive signals from a remote detector connected to the receiver (by dedicated wiring), and circuitry to superimpose information concerning the receiver.
  • Each of the detectors is separately wired to a remote operation panel connected to the receiver.
  • the system is unsuited to domestic applications, being complex to install and requiring substantial cost additional to that of the television receiver.
  • the present invention can result in an installation which is particularly suited to the domestic environment, in that it can be set up at minimal additional expense, by virtue of using the teletext facilities and the mains wiring. Moreover, such an installation can easily and quickly be set up.
  • the detector(s) may be, inter alia, a burglar alarm, a smoke detector an "assistance” alarm or a microphone or any combination of these.
  • the utilisation means comprises means to instruct the teletext unit in the receiver to effect an appropriate display of the receiver, the instruction means being actuable by an output of the identification means representing reception of an alert signal from a detector.
  • the instruction means being actuable by an output of the identification means representing reception of an alert signal from a detector.
  • the utilisation means has means to superimpose wording or images or both on the television screen, and may also incorporate an audio signal or a light or similar indicator on the television housing or any combination of these; all these arrangements provide particularly beneficial ways of attracting attention.
  • the television viewer is notified whenever a detector is activated, so that surveillance of premises can be maintained while watching the television receiver.
  • the means to alter the output includes means to lower the sound output of the set.
  • the television set receives the alert signal from the detector the television sound is automatically decreased or turned off.
  • the receiver is adjusted in order to facilitate attending to the cause of the alert signal and enabling the viewer to do this more quickly.
  • the invention also provides an electric installation comprising a television receiver as defined above, and at least one detector of signals which is remote from the receiver and is connected to the receiver via the electrical mains wiring system such that, in use, upon detection of a signal that detector transmits an alert signal to the receiver.
  • connection between the at least one detector and the receiver may include infra-red, ultrasound or pulsed light (e.g. coherent) transmission of the alert signal before it passes along the electrical mains wiring system; this would avoid cabling between the detector and the nearest input to the mains, such cabling could be inconvenient, unsightly, expensive and may be hazardous.
  • infra-red, ultrasound or pulsed light e.g. coherent
  • a television receiver 1 is linked with a number of detectors 2, 3, 4, 5 and 6, throughout a home, so that when any detector is activated, an appropriate message identifying the relevant source is flashed onto the television screen in order to notify the viewer.
  • the connection between detectors and the television receiver utilises the existing mains supply wiring 7.
  • Some detectors suitable for surveillance by the illustrated installation include ultra-sonic burglar alarms 2 and 3 located in different rooms, a smoke detector 4, . an "assistance” alarm 5 (described in greater detail below) and a microphone 6 for detecting the crying of a baby.
  • burglar alarm 2 The operation of burglar alarm 2 will be described in more detail, the other detectors working in the same way except for the modifications described later.
  • a demodulator in the television receiver 1 retrieves the digital signal from the live and neutral lines and feeds it to a microprocessor unit which analyses the source coding of the signal. Ony if this corresponds to an actual code used in the particular installation does the microprocessor send a command signal to the teletext unit of receiver 1 to superimpose for five seconds the words "Burglar alarm 3" on the screen picture and to thereby indicate that the burglar alarm 3 has been activated.
  • the unit may send additional command signals to other destinations, e.g. for a signal from a burglar alarm a bell may be switched on and/or an alarm in a neighbouring house or in a police station may be activated.
  • the "assistance" alarm 5 enables a person in one room to request assistance from the television viewer in another room, this being particularly useful for the elderly and handicapped"
  • the user switches on the alarm 5, causing a transmitter 8 to emit pulses of infra-red radiation, and directs it towards an infra-red receiver 9 which is mounted on a wall and which is electrically connected, via a coder/modulator 9' to the electrical mains wiring circuit 7.
  • alarm 5 can be continuously carried by the user.
  • the infra-red link is replaced by electric cable, the alarm being either fixed in one position or capable only of limited movement.
  • a detector and the associated coder/modulator may be in a single unit with pins to slide directly into a standard mains power socket; alternatively the unit may be spaced from, but electrically connected to (via electric cables) the mains circuitry 7 during use.
  • the installation can include a number of detectors of any one type (e.g. the "assistance” alarm) in differrent rooms of a building, in which case the television receiver 1 displays an alert message indicating the location, as well as the type of detector which has been activated.
  • any one type e.g. the "assistance” alarm
  • the television receiver 1 displays an alert message indicating the location, as well as the type of detector which has been activated.
  • the present invention can be used in any other suitable location for example in a hotel or in a nursing home.
