Definitions

  • the present invention refers to a method for programming television signal receivers, herein intending television signal receivers as, television sets, video tape recorders and all other appliances able to receive and elaborate television signals.
  • every television signal receiver in particular a normal television set or video tape recorder, has to be programmed upon installation before being able to easily receive the various television programs available.
  • the purpose of the present invention is that of indicating a method for programming a television signal receivers being faster and easier.
  • a further purpose of the present invention is that of indicating a television signal receiver, with appropriate memory means, able to implement in an optimal manner the aforementioned method. So as to reach such purpose the present invention has as its subject a method for ⁇ programming a television signal receiver having the characteristics as described in the first claim, and a television signal receiver, which can be connected to appropriate memory means, that implements the aforementioned method.
  • FIG. 1 schematically represents the key board of a remote control device apt at enabling the method according to the invention
  • figure 2 schematically represents the circuit of the remote control device illustrated in figure 1;
  • figure 3 schematically represents the circuit inserted in the television signals receiver which implements the invention, according to a variation of the solution.
  • Figure 1 represents a remote control device indicated with the symbol TC; in the figure ten numeric buttons or keys are visible (from 0 to 9) that have the purpose of composing the identifying numbers of the television channels to be tuned according to the CCIR standard and the numbers of programs (keys) to be associated with them; in this case the television signal receiver shall be of the frequency synthesis type or, if voltage synthesis, with the possibility of carrying out the direct channel paging, as described in the European patent application n° 93116403.2.
  • buttons or keys are visible and in particular:
  • - key P program mode
  • - key CH channel mode key S: sequential selection of the type of channellization (CCIR, CATV, Hyperband, etc.);
  • microprocessor (a simple 4 bit microprocessor is sufficient) ;
  • - EAROM non volatile memory for memorising tuning data (a small memory of 2K BIT could suffice, or 256 bytes, for 100 programs) ;
  • - TX transmitter of signals of infra-red rays.
  • the programming of the remote control device takes place only once and remains valid for tuning all the receivers installed in the same area, this is done as follows : - entering the programming mode of the remote control device TC (for instance simultaneously pressing 3 keys, for protection against accidental manoeuvres; or a small hole could be provided to be enabled by way of the point of a pencil; - pressing the key P and the number of the desired program;
  • the remote control device TC shall therefore be a service remote control, given, or in addition to the normal remote control of the receiver, or to the personnel of the technical assistance service or to the installer, for allowing to program the tuning of a plurality of television signal receivers, without having to repeat each time the same sequence of commands, on every appliance.
  • the reference number 16 indicates the receiving antenna; number 17 indicates the tuner, which is supposedly of the known type known as "frequency synthesis", and that allows the direct selection, inputting the channel number assigned according to the standard CCIR by a certain broadcaster, the television signal intercepted by the receiving antenna.
  • Reference number 18 indicates, in the same figure, the amplifier of the intermediate frequency signal; number 19 indicates the circuit of the video detector and number 20 a preamplifier of the detected video signal
  • Reference number 26 indicates a circuitry block that generates in a known way the vertical and horizontal synchronism signals starting from the appropriate impulses contained in the preamplified video signal, indicated with the reference number 30.
  • Block 26 also contains a known coincidence circuit, that verifies whether the incoming signal is synchronised with the locally produced deflection signals, in such case generating an appropriate coincidence signal, which reaches a terminal, indicated with C, of the successive circuitry block 27, which is a control circuit, described in more detail later in the text.
  • Reference number 200 indicates a remote control signal transmitter, for instance of the usual infra-red rays type; such transmitter contains a plurality of command keys (for simplicity not illustrated in the figure), from among which a key MM can be provided for initiating the memorisation of the receivable signals
  • Reference number 201 indicates the receiver of the remote control signals; it is coupled to the control circuit 27.
  • Reference number 29 indicates a read and write memory, of the non volatile type; such memory is connected to the circuit 27 by way of a bi-directional bus BB and has the purpose of memorising in a known way the tuning information relative to a plurality of receivable television stations.
  • the control circuit 27 is a logic circuit, for instance a microprocessor, containing or associated to a read only memory R, in which a series of operative instructions and data have been memorised; such data comprises a rule for memorising within the memory 29 the tuning information relative to the programs and to the channels, received by the remote control 200 according to the known way, or by the service remote control TC, illustrated in figures 1 and 2, according to the invention, once the automatic memorisation has been enabled by way of the key I of the remote control device TC .
  • a logic circuit for instance a microprocessor, containing or associated to a read only memory R, in which a series of operative instructions and data have been memorised; such data comprises a rule for memorising within the memory 29 the tuning information relative to the programs and to the channels, received by the remote control 200 according to the known way, or by the service remote control TC, illustrated in figures 1 and 2, according to the invention, once the automatic memorisation has been enabled by way of the key I of the remote control device TC .
  • the circuit 27 manages the functioning of the receiver; decodes the commands sent by the user, by way of the remote control 200 or by the installer by way of the remote control device TC; provides for tuning the receivable television signals by way of the antenna 16 and the tuner 17; provides for memorising the tuning information relative to such signals and to recall it, if necessary, for providing to tune once again a signal preferred by the user.
  • the remote control device TC After having programmed the remote control device TC as mentioned above, i.e. after having memorised in the device the channel/program combinations for all the receivable broadcasters in the area, it is sufficient to press the key I on the remote control TC. According to this variant of the invention, as opposed to transmitting all the commands that the receiver would expect to receive, once received the command which prepares it to operate in the programming mode of memorising the stations to be tuned, the remote control device TC, would limit itself to transmit a sequence of data pairs, where every pair has data relative to the program selected and data relative to the channel that has to be associated to the mentioned program.
  • the transmission will start, by way of the remote control TC, in sequence of all the memorised combinations; the receiver as it is at the beginning of said sequence will have received the command to enter into the station memorisation mode, provides to memorise in the memory 29 the sequence of combinations received; at the end an appropriate signal will inform the television receiver of the end of transmission, and the receiver will return to the normal mode. In this mode the time necessary for programming the receiver is minimised.
  • the television signals receiver has to be realised in a dedicated manner, in particular so as to be able to function with such type of service remote control, which only transmits data pairs for the memory; i.e. the code transmitted by the remote control and which places the receiver in the station memorisation mode, it will also assure that the microprocessor, which manages the memorisation of the stations, interprets the successive codes as data pairs for the memory and not as commands for continuing the memorisation.
  • the advantages of the method for programming television signal receivers subject of the present invention are also clear. In particular they consist in the fact that it is necessary to carry out the task of programming only once, after which the effective programming of a receiver of signals that has to work in the same area requires that only a single key be pressed on the remote control device.
  • Such service remote control is found to be particularly advantageous in use with retailers or installers because, upon the sale of the television appliance or its installation, with the previously programmed remote control, in a very short time the receiver which is about to be sold or installed can be programmed. It is clear that the described method for programming television signal receivers is more advantageous than those previously known; it is also clear that numerous variants are possible by the skilled man, to the method and to the means necessary for programming television signal receivers described as an example, without for this departing from the novelty principles inherent in the invention.
  • Another possible variant may consist in providing a service remote control device which incorporates a circuit able to emit a plurality of different codes.
  • the service remote control is able to operate communicating with different chassis of the same brand name or even of different brands, thus realising a universal remote control.
