Abstract
Description
- The present invention relates to a television receiver, and also to an electrical installation including a television receiver.
- In "Patents Abstracts of Japan" Volume 7 November 4 (E-151) (1149) January 8 1983 concerning Japanese Patent Application 57-164684 published on 9 October 1982, there is disclosed 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 provides a television receiver characterised by incorporating circuits having:
- means to identify an alert signal from at least one signal detector which, in use, is remote from the receiver and is connected to the receiver via the electrical mains wiring system; and
- means to utilise teletext facilities of the receiver to effect alteration of the output, during operation of the receiver, of the television receiver upon identification of such an alert signal in order to indicate that such an alert signal has been received at the receiver.
- In this way, 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.
- Preferably, 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. Such an arrangement provides effective indication of the alert signal in a straighforward manner.
- Preferably, 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. Thus the television viewer is notified whenever a detector is activated, so that surveillance of premises can be maintained while watching the television receiver.
- In another form of the invention the means to alter the output includes means to lower the sound output of the set. Thus when the television set receives the alert signal from the detector the television sound is automatically decreased or turned off.
- In this way, not only is the viewer readily and effectively made aware of the alert signal, but also 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.
- The 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.
- In order that the invention may more readily be understood, a description is now given, by way of example only, reference being made to the accompanying sole Figure which is a schematic diagram of an electrical installation embodying the present invention.
- In the illustrated installation a television receiver 1 is linked with a number of
detectors - Some detectors suitable for surveillance by the illustrated installation include
ultra-sonic burglar alarms microphone 6 for detecting the crying of a baby. - 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. - When
burglar alarm 2 detects a movement in the room under surveillance an electrical signal is passed to a coder/modulator 2' which adds a code identifying the source, the resulting signal now comprising two bytes of information. Using frequency shift key techniques, with frequencies of 150 and 152 KHz (or whatever frequencies are appropriate subsequent to the pending standardization discussions), the signal is converted to a digital form which is transmitted down the live and neutral lines of the electrical mains wiring circuit 7 to television receiver 1. - 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 theburglar alarm 3 has been activated. - Clearly the particular operations of the microprocessor may vary somewhat dependent on the source from which the signal derives, for example 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" In operation, the user switches on thealarm 5, causing atransmitter 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. In this form,alarm 5 can be continuously carried by the user. In other forms 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.
- The present invention can be used in any other suitable location for example in a hotel or in a nursing home.
