Definitions

  • the present invention relates to television receivers tunable to transmitters of different frequencies, in particular television sets, in particular those high-frequency receivers which can be programmed by the user in such a way that they automatically start to output or reproduce the program of a specific transmitter at a program-defined point in time.
  • television signal receivers according to the preamble of claim 1, especially television sets, which have two receiving parts, but in these devices the second receiving part is used exclusively for the simultaneous display of two programs with the aid of a picture-in-picture modulator to enable a screen.
  • the object of the invention is to further develop the generic television signal receiver in such a way that it draws the attention of a user to the start of an expected broadcast of a second transmitter while the user is watching the program of a first station at the correct point in time, but not previously known to the user.
  • the warning signal output by the detector can be a signal that can be perceived by the user, for example an acoustic signal, which prompts him to change the set transmitter.
  • a control unit is preferably provided which receives the warning signal and then automatically sends the signal of the monitored transmitter to the connection. This can be done by the control unit tuning the first receiving part to the frequency monitored by the second receiving part.
  • Another possibility is to give output signals of the second receiving part directly to the connection after receiving the warning signal, instead of the previously output signal of the first receiving part or in the form of a signal composed of signals from both receiving parts, for example a picture-in-picture Signal.
  • 1 and 2 are each a block diagram of a television signal receiver according to the invention.
  • Fig. 1 the block diagram of a television set according to the invention is shown. It comprises two receiving parts 1, 2 which receive television signals from a common source, an antenna or a cable and output a signal CVBS1 or CVBS2 obtained therefrom.
  • a control unit 3 is connected to a control input of each receiving part 1, 2, so that it is able to specify the frequency of two transmitters A, B to which the receiving part 1 or 2 is tuned.
  • the control unit derives the frequency to be specified for the receiving part 2 from programming data which the user enters via a dialog unit 4.
  • Such dialogue units, the type of Data to be entered and their processing are known from VPS video recorders and do not need to be explained here.
  • a detector 5 is connected to the output of the second receiving part 2.
  • the latter monitors the output signal of the second receiving part 2 by extracting VPS / PDC (program delivery control) data from the output signal and comparing this with a character which is communicated to it by the control unit and which is also from the programming data derives.
  • VPS / PDC program delivery control
  • the first receiving part 1 can be tuned to the frequency of the transmitter A.
  • the signal CVBS1 received by the receiving part 1 from this transmitter is output via the connection 6 to the control electronics 7 of a picture tube 8.
  • the detector As soon as the detector has detected the sign, it issues a warning signal to the control unit 3. This then tunes the first receiver part 1 to the monitored frequency of the transmitter B, so that from now on its program is displayed.
  • Fig. 2 shows a second television set according to the invention.
  • Receiving parts 1, 2 and dialogue unit 4 are identical to those from FIG. 1.
  • Two detectors 5 are provided in order to monitor the CVBS signal of one of the two receiving parts.
  • the control unit 3 "comprises a control circuit 9 and a picture-in-picture modulator 10.
  • the control circuit 9 selects one of the two receiving parts, e.g. receiving part 1, whose signals from picture-in-picture modulator 10 remain unchanged. to be passed on to the screen 8. If programming is carried out, the control circuit 9 instructs the detector 5 assigned to the receiving part 2 to monitor its signal.
  • the control circuit 9 controls the picture-in-picture modulator 10 so that it inserts the picture signal coming from the receiving part 2 as picture-in-picture into the screen display.
  • the user then has the choice of whether he wants to change the station immediately or continues to follow the previous station for a while. If he opts for the former, the control circuit controls the modulator 9 again, so that it only passes on the signals from the receiving part 2 to fill the screen.
  • the two receiving parts have thus swapped their functions; If programming is carried out again later, the signal of the first receiving part 1 can be monitored and that of the second can be displayed during this time.
  • the two detectors 5 can also be replaced by a detector which can be assigned to the two receiving parts by multiples.

Abstract

L'invention concerne un récepteur de signaux de télévision accordable à différents émetteurs et comprenant deux parties récepteurs (1, 2) accordables à différentes fréquences et une connexion (6) permettant d'envoyer des signaux de sortie de la première partie récepteur (1) à un dispositif de reproduction (7, 8). Pour faciliter un changement d'émetteur à un moment non encore connu avec précision par l'utilisateur, ce récepteur est caractérisé en ce qu'un détecteur (5) est relié à la sortie de la deuxième partie récepteur (2). Cette sortie surveille le signal de sortie de la deuxième partie récepteur (2) et émet un signal lorsqu'elle détecte un signe déterminé dans le signal de sortie.
