  • the user uses a remote control unit 60 usually equipped with a transmitter antenna 62.
  • the remote control unit 60 sends command signals to a receiver stage 50 of the television 10, received via an antenna 52.
  • These signals are interpreted by the receiver 50 which sends suitable commands to the television stages 10 to perform the action requested, these too according to the television's own protocols.
  • the control by the receiver 50 of the tuner 20 can be schematised by a signal line 56, and of the stage 30 by a signal line 54.
  • the receiver 50 can for example vary the tuning frequency (channel) or audio volume and generally perform or control all the functions provided in the television. Protocol is taken to mean the signal coding by which the various stages of the television dialogue with each other.
  • the main object of the invention is to overcome this problem.
  • a further object is to give the user the chance to choose his favourite program/s and optimise the use of the television.
  • the device is characterised by a circuit or architecture which implements various stages, integrated or separate .
  • the stages may be hardware (such as electronic circuits, boards or FPGA) and/or implemented functionally using software, for example via a program which performs the functions described for the stages.
  • a stage receives a signal relative to a functional parameter of the television from a receiver circuit of wireless signals coming from a remote control unit.
  • Another stage interprets such signal according to the predefined data protocol of the television and depending on this signal decides a variation of state of the television.
  • a stage After which a stage sends a command signal according to the data protocol to the receiver so as to make the receiver act to obtain the variation of state.

  • the processing unit may be programd for (or able to) detecting the publicity break by identifying a discontinuity in the video and/or audio signal.
  • the processing unit may be programd for (or able to) detecting the publicity break or other program by comparing the video signal with stored signal sequences.

  • the signals sent and received by the device 70 are coded in compliance with a data protocol used inside the television 10, and are processed and interpreted by a processing unit 90, such as a microprocessor. Even though the functioning logic of the device 70 could be made with lumped components, it is preferred to use a programmable unit and instruct it using software.

  • the device 70 makes it possible to automatically control all the functions of television 10. By receiving and managing the signals of the stages 20, 30, 40 and by the lines 74, 76 and 78 it sends program commands to the receiver 50 which in turn varies one or more operating parameters of the television 10 (for example the transmitted program, the channel, the turning on/off of the television, the control of the PIP, the volume etc.).

  • the device 70 may compare the picture viewed with other pictures or sample sequences stored inside it and switch to a different program or channel should the current compared pictures prove identical or similar, telling the user that he is watching something he has already seen, such as the advertisements. To such purpose the device 70 can make the television change channel automatically, for example by switching the current channel to one of the AV channels. Any variations in any of the television parameters may be used as switching criteria, such as brightness, contrast, sound or quantity of black, duration or value of the black.
  • the device 70 For example should the device 70 detect the absence of brightness, contrast, luminance or chrominance below a certain threshold, and/or detect a value of black protracted for a certain period, the device 70 gives a command, via the receiver 50, to the tuner 20 to change channel, frequency or program (if there are various programs in a frame of the same frequency).

  • the device 70 can command not just one television but all those connected to it which are on the same channel. Each channel has its own programming, and the software in the device 70 makes the tuner 20 switch from the current channel to another channel when the command is given.
