Definitions

  • the invention relates to a TV signal receiver.
  • TV programs of a given length are regularly interrupted by, for example commercials or other information.
  • Such messages are usually concentrated in a standard packet which is sent to everyone.
  • Many viewers regard at least a part of such a packet as being useless, for they prefer information about other subjects such as, for example stock exchange news or the weather forecast instead of commercials, or they prefer, for example commercials about products in which they are specially interested.
  • the TV signal receiver has an input terminal for receiving an input signal, a tuner for deriving a first TV signal from the input signal, and a device for storing and reading at least a plurality of second TV signal blocks to be derived from the input signal in/ from a memory, said first TV signal having interruptions during which a second TV signal block is insertable, the interruptions being provided with a first control signal for controlling the memory in such a way that at least one second TV signal block is read from the memory for insertion into an interruption in the first TV signal so as to obtain a composite TV signal, and further having an output terminal for supplying the composite TV signal.
  • second TV signal blocks which do not form part of the first TV signal, referred to as the main signal, can be selectively added to the main signal via the signal receiver.
  • These second TV signal blocks are stored in a memory in the receiver from which they are read again at the moment when there is an interruption in the main signal. This is effected in response to a first control signal comprising information about the positions of the interruptions.
  • the first control signals may precede the interruptions in the input signal. They may also be present, for example at the start of the interruptions.
  • the second TV signal blocks are linked with a second control signal. Said control signal has to activate the memory in time so that the second TV signal blocks can be stored when they arrive.
  • the first and the second control signals are detected by detection means.
  • the detection means may, for example, comprise one or more detectors or may consist of a control system unit.
  • the TV signal receiver is switchable between two modes. In the first mode, second TV signal blocks are read from the memory and inserted into the interruptions. In the second mode, the second TV signal blocks received at the input terminal are stored in the memory where they create an assortment of second TV signal blocks. In both cases, use is made of a control signal which ensures that the second TV signal blocks are inserted or stored at the suitable moment.
  • the TV signal receiver may be provided with input means with which a profile of second TV signal blocks of the desired contents can be selected. Such a selection may take place before the second TV signal blocks are sent to the receiver.
  • a signal supplied from an output terminal of the signal receiver is sent with the relevant information to the broadcaster or service provider which subsequently only sends the desired second TV signal blocks and, based on a control signal, switches the TV signal receiver to the second mode so that the second TV signal blocks can be stored in the memory.
  • the broadcaster or service provider may monitor the content of the second TV signal blocks himself. To this end, the broadcaster or service provider may determine the preferential profile based on the situation of the user. Elements such as the age of the user and his purchasing behaviour during a certian period may play an important role.
  • the broadcaster or service provider may send a full packet of second TV signals to the device and store them in the memory.
  • the selection is made known to the memory so that only second TV signal blocks having the desired contents are retrieved from the memory by means of a selector and inserted into the interruptions. The selection may take place before the information packets are stored in the memory. Then, the memory will only comprise the information of which the content meets the preferential profile. In this way a smaller memory would suffice.
  • Fig. 1(a) and 1(b) show a first and a second embodiment of a system provided with a broadcaster or service provider and at least one TV signal receiver according to the invention
  • Fig. 2 shows a third embodiment of a system provided with a broadcaster or service provider and at least one TV signal receiver according to the invention, in which a profile of desired second TV signal blocks is made known to the broadcaster or service provider;
  • Fig. 3 shows a fourth embodiment of a system provided with a broadcaster or service provider and at least one TV signal receiver according to the invention, in which the preferential profile of second TV signal blocks is presented to the memory in the receiver.
  • Fig. 1(a) shows diagrammatically a system 1 comprising a broadcaster or service provider 3 and a TV signal receiver 5.
  • the TV signal receiver 5 has an input terminal 7 and an output terminal 9.
  • the TV signals transmitted by the broadcaster or service provider 3 are received at the input terminal 7 of the TV signal receiver 5.
  • This will be further referred to as the input signal.
  • the input signal may be split up into two different types of signals.
  • the first type relates to the first TV signals, in other words, the main programs. These first TV signals have interruptions.
  • the second type relates to the second TV signal blocks comprising information such as commercials, stock exchange news, the weather forecast, or commercials on given subjects, etc.
  • the contents of such information are, however, often considered to be too diverse by the user who wishes to receive, for example only information about given subjects. It is an object of the invention to provide a solution in this respect.
  • the input signal received at the input terminal 7 is applied to a tuner 11, so that a first TV signal is selected from the presented first TV signals.
  • the detection means comprise two detectors 13, 15. Each of the first TV signals has a first control signal with which the position of the interruptions is indicated. This control signal is analyzed by a first detector 13 which is arranged behind the tuner 11.
  • the input signal may also comprise one or more second TV signal blocks.
  • the second TV signal blocks are linked with a second control signal which is detected by a second detector 15.
  • the detector 15 detects such a control signal, it will activate a memory 17 in such a way that the second TV signal blocks will be stored in this memory.
  • the first detector 13 When the first detector 13 signalizes an interruption in the first TV signal selected by the tuner 11, this detector will subsequently activate the memory 17.
  • the memory 17 will send one or more of the stored second TV signal blocks to a signal- combining unit 19 which also receives the first TV signal selected by the tuner 11.
  • the first detector 13 not only activates the memory on the basis of the first control signal but also the signal-combining unit 19.
  • the second TV signal blocks are inserted into the interruptions in the first TV signal at the appropriate moment in the signal-combining unit, so that a composite TV signal is obtained.
  • the composite TV signal is subsequently applied to the output terminal 9 of the receiver.
  • Fig. 1(b) shows another embodiment of the TV signal receiver according to the present invention.
  • the tuner 11 and the first and the second detector 13, 15 are substituted by a first and a second tuner 12, 14 and a system control unit 16 constituting the detection means.
  • the input signal received at the input terminal 7 is applied to a first tuner 12, so that a first TV signal is selected from the presented first TV signals.
  • the input signal is alos applied to a second tuner 14, so that the second TV signal blocks can be selected from the input signal.
  • the second tuner 14 may be system controlled and decodes incoming messages before sending them to the memory.
  • the first control signal which indicates the interruptions in the first TV signal and the second control signal which is linked with the second TV signal blocks are detected by the control system unit 16.
  • Said control unit 16 activates the memory in reaction to the second control signal, so that the second TV signal blocks can be stored when they arrive.
  • the memory is activated by the system control unit so that a second TV signal block will be sent from the memory to the signal-combining unit 19 to be inserted in an interruption.
  • the system control unit 16 also activates the signal-combining unit 19.
  • the receiver is thus switchable between two modes.
  • the first mode one or more second TV signal blocks are read from the memory and inserted into an interruption in the first TV signal. This is effected on the basis of the first control signal with which the interruptions are provided and with which the memory is activated so as to release stored second TV signal blocks.
  • the second mode based on the second control signals, one or more second TV signal blocks are stored in the memory so that they can be inserted into the first TV signal at a later stage during possible interruptions.
  • the second TV signal blocks may be sent to the TV signal receiver at any moment because they can be stored in a memory anyway and can be retrieved at a later stage when there are interruptions.
  • the TV signal receiver 5 is preferably provided with input means 23 for presenting a preferential profile of themes or subjects about which information is desired. However, this profile may be presented in different manners.
  • Fig. 2 shows an embodiment in which a first possibility of presenting a preferential profile is illustrated.
  • the profile is supplied from an output terminal 21 of the TV signal receiver 5.
  • feedback means 25 may be provided, ensuring that the signal supplied from this output terminal 21 is sent to the broadcaster or service provider 3 so that the broadcaster or service provider can send packets of second TV signal blocks with the desired profile to the TV signal receiver 5.
  • Fig. 3 shows an embodiment in which a second possibility of presenting a preferential profile is illustrated.
  • the memory 17 may comprise, for example, the full information packet of second TV signal blocks transmitted by the broadcaster or service provider 3 and the desired profile is passed on to the memory 17 with the aid of the input means 23.
  • the input means 23 are connected to the memory 17 via a selector 27.
  • the broadcaster or service provider 3 may monitor the content of the second TV signal blocks himself. To this end, the broadcaster or service provider 3 may determine the preferential profile based on the situation of the user. Elements such as the age of the user and his purchasing behaviour during a certian period may play an important role.
  • the input means 23 may consist of, for example a keyboard.
  • Position information about the position of the second TV signal blocks on the record carrier is stored in the directory which is recorded in the part P 5 of the tracks T, and T 2 so that the second TV signal blocks can be retrieved if an interruption in a received first TV signal is to be filled up.
