Description:
[0001]    The present invention concerns a set of devices comprising at least one receiver device and at least one portable device, said receiver device comprising means for receiving a multichannel signal capable of preserving a part of the signal transmitted on a particular channel allowing information to be received in the form of a programme, conversion means associated with propagation means for broadcasting said information and communication means, the set of devices further comprising a portable object including an electronic module for the operation of said portable object, the electronic module comprising at least a calculation unit and a wireless communication circuit able to communicate with the communication means of the receiver device. 
       BACKGROUND OF THE INVENTION 
       [0002]    There are known receiver devices such as television receivers or radio receivers that receive video and/or sound information for re-transmission to users. The received signal is transmitted on a frequency band and the receiver device is capable of selecting a precise frequency from within this frequency band. The signals are currently often digital signals. For a television receiver, these different signals correspond to different television channels whereas for a radio receiver, the different signals correspond to different radio stations. 
         [0003]    The received information takes the form of a video and/or sound programme. 
         [0004]    The user manipulates said receiver device, or uses a dedicated remote control for the device, in order to select the desired channel and thus watch and/or listen to the programme that he wishes. 
         [0005]    To improve the use of these receiver devices, the user is able to programme the device with a list of favourites, i.e. to create shortcuts to immediately reach his preferred channels or stations. 
         [0006]    However, this only enables the user to go to his preferred channels or stations and not to his preferred programme or type of programme, so that he must always scan all the channels or stations to see whether a programme suits him. 
       SUMMARY OF THE INVENTION 
       [0007]    It is therefore an object of the present invention to overcome the drawbacks of the prior art by providing a set of devices with improved connectivity. 
         [0008]    To this end, the present invention concerns a set of devices comprising at least one receiver device and at least one portable device, said receiver device comprising means for receiving a multichannel signal capable of preserving a part of the signal transmitted on a particular channel allowing information to be received in the form of a programme, conversion means associated with propagation means for broadcasting said information and communication means, the set of devices further comprising a portable object including an electronic module for the operation of said portable object, the electronic module comprising at least a calculation unit and a wireless communication circuit able to communicate with the communication means of the receiver device, 
         [0009]    characterized in that each particular channel and each programme is identified by at least one identifier, the portable object being programmed with at least one specific identifier associated with a particular channel and/or at least one programme and in that the portable object is capable of detecting, via the wireless communication circuit, the presence of at least one receiver device belonging to said set of devices and of acting on said at least one receiver device in order to change the particular channel and to select a particular channel whose identifier or whose programme currently being broadcast has at least one identifier identical to the identifier programmed in the portable object. 
         [0010]    In a first advantageous embodiment, the multichannel signal is analogue or digital. 
         [0011]    In a second advantageous embodiment, the wireless communication means are provided with at least one interface using at least one protocol. 
         [0012]    In a third advantageous embodiment, the wireless communication means are provided with at least two interfaces each using a protocol. 
         [0013]    In a fourth advantageous embodiment, the protocols are chosen from the list including: Bluetooth Smart®, WiFi, NFC or other proprietary or standard protocols. 
         [0014]    In a fifth advantageous embodiment, said portable object further comprises control means and display means. 
         [0015]    In a sixth advantageous embodiment, said portable object is chosen from the list including a watch or a bracelet or a mobile telephone or a smart phone or a remote control or any device able to interact with a receiver device.

     DETAILED DESCRIPTION 
       [0019]    A set of devices  1  according to the present invention is represented in  FIGS. 1 and 2 . Such a set of devices  1  comprises at least one receiver device  2  and at least one portable object  3 . 
         [0020]    Receiver device  2  comprises receiver means  21 , such as a receiver circuit, capable of receiving a multichannel analogue or digital signal. 
         [0021]    In the case of an analogue signal (used in the following description), the multichannel signal (S_MC) is an electromagnetic signal transmitted on a frequency band by a transmitter  100 . The receiver device is capable of preserving a part of the signal transmitted on a particular channel, here a particular frequency, and of rejecting the signal parts transmitted on the other frequencies. The electromagnetic signal is transmitted by a transmitter source and may be transmitted in waves or by cables. 
         [0022]    Each part of the signal transmitted on a particular frequency allows the user to receive information in the form of a programme. Each particular frequency of the frequency band bears a frequency identifier (ID_Y). Further, each programme bears an identifier (ID_X) associated with the programme. This programme identifier (ID_X) may take the form of a multi-character code. The code comprises several groups of characters each of which provides an indication. These indications may relate to the particular frequency on which the programme is transmitted, the category of the programme, i.e. whether it is sport, entertainment, culture, news, the genre, i.e. the sport genre: football, rugby, car racing, and even more precise information, such as, for example, the type of programme, i.e. whether it is a national championship football match or a European Cup football match or a World Cup football match. 
         [0023]    For example, the programme identifier (ID_X) may be encoded in a 12-character code comprising four groups of three characters (for example the identifier X is encoded as follows: AAABBBCCCDDD where AAA corresponds to the channel, BBB corresponds to the category, CCC corresponds to the genre and DDD corresponds to the type), each group (AAA, BBB, CCC, DDD) corresponding to a type of information. These groups of three characters (AAA, BBB, CCC, DDD) may form part of a database. 
         [0024]    Receiver device  2  further comprises conversion means  22 , such as a demodulator, for converting the selected part of the signal transmitted on a particular frequency into an information signal which will be able to be used by propagation means  23 , such as a screen and/or loudspeakers. 
         [0025]    It is understood here that receiver device  2  may be a digital or analogue television receiver or a digital or analogue radio receiver or a computer or a touch tablet or any device able to receive, process and convert a multichannel signal for broadcast. 
         [0026]    Receiver device  2  further comprises a communication circuit  24  enabling said device  2  to communicate with other devices, communication module  24  comprising a wired communication circuit  24   a  and/or a wireless communication circuit  24   b.  The wireless communication circuit is provided with an interface using a protocol selected from among the following list of protocols: Bluetooth Smart®, WiFi, near field communication (NFC) or other proprietary or standard protocols. 
         [0027]    Of course, the wireless communication circuit could be provided with several interfaces each using a protocol, or only one interface able to use several different protocols. 
         [0028]    Further, receiver device  2  could also includes control means  25 . 
         [0029]    Portable object  3  comprises an electronic module  31  for the operation of said portable device. This electronic module comprises at least a calculation unit  32  and a wireless communication circuit  33 . The wireless communication circuit is provided with an interface using a protocol selected from among the following list of protocols: Bluetooth Smart®, WiFi, near field communication (NFC) or other proprietary or standard protocols. 
         [0030]    Of course, the wireless communication circuit could be provided with several interfaces each using a protocol, or only one interface able to use several different protocols. 
         [0031]    Electronic module  31  may also comprise display means to allow the user to read information and control means to allow the user to operate the portable object. 
         [0032]    For example, the portable object may be a watch or a bracelet or a mobile telephone or a smartphone or a remote control. Portable object  3  is also provided with control means  34 , such as push-pieces or touch keys, and may be provided with display means  35 . The display means may be used for utilisation of one function or may be used for several functions, and may be hands  35   a  and/or screens, for example of the LCD type  35   b.    
         [0033]    Advantageously according to the invention, said at least one receiver device and said at least one portable object of the set of devices each comprise a specific tag (E_i) associated with said set. This specific tag is like an identifier that allows the receiver devices and portable objects to recognise each other via a recognition protocol. 
         [0034]    Indeed, portable object  3  is configured such that its electronic module  31  and communication circuit  33  regularly test, within its communication area, for the presence of receiver devices on the basis of the specific tag with a positive reply (Y) or a negative reply (N). 
         [0035]    When a test for presence of a receiver device is affirmative, the portable object is configured to interact with the receiver device. 
         [0036]    Of course, the test for presence of a receiver device  2  is carried out in an area equivalent to the radius of action of the communication circuit of the portable object. For example, if the Bluetooth Smart® protocol is used, the radius of action will be around 10 m, whereas if NFC is used, the radius of action will instead be around 2 to 30 cm. It will be understood that it is possible to adjust the radius of action of said communication circuit  24 , by modifying the components or parameters of communication circuit  24  of portable object  3 . This would make it possible, for example, to obtain a communication circuit  24  using the Bluetooth Smart® protocol and having a range of 2 m. 
         [0037]    Indeed, advantageously according to the invention, portable object  3  is pre-programmed with an identifier (ID_P) associated with the programmes or with the channel. 
         [0038]    Consequently, when portable object  3  is close to a receiver device belonging to set of devices  1 , portable object  3  acts on this receiver device by communicating the identifier associated with the programmes or with the channel by sending a signal containing a command. 
         [0039]    If the identifier is associated with a programme, the interaction between portable object  3  and receive advice  2  causes a reaction, on the part of receiver device  2 , that consists in changing the particular frequency selected and scanning the various frequencies of the electromagnetic signal to select the frequency on which a programme with the same identifier is being broadcast. 
         [0040]    For example, the portable object is programmed with an identifier associated with sports programmes and more particularly associated with the genre of football. With the example identifier encoded as follows: AAABBBCCCDDD (where AAA corresponds to the channel, BBB corresponds to the category, CCC corresponds to the genre, and DDD corresponds to the type), the CCC part of the code is the programmed part. When the portable object is close to a receiver device belonging to the set of devices, the programmed code part CCC is communicated to the receiver device which will scan all the particular frequencies to select the particular frequency on which, at the same moment, a sports programme associated with football is being broadcast. 
         [0041]    If the identifier is associated with a channel, i.e. with a particular frequency, the interaction between portable object  3  and receiver device  2  causes a reaction, on the part of receiver device  2 , that consists in changing the particular frequency by scanning the various frequencies of the electromagnetic signal to select the frequency associated with the programmed identifier. Of course, in the case of a multichannel digital signal, the reaction consists in changing the particular channel by scanning the various channels of the multichannel signal to select the channel associated with the programmed identifier. 
         [0042]    The interaction between portable object  3  and receiver device  2  may be automatic, such that the change in frequency of receiver device  2  occurs automatically without external intervention. 
         [0043]    However, this interaction may be semi-automatic so that there is a confirmation step in which the user is informed that a compatible receiver device  2 , i.e. belonging to the set of devices, has been detected. The user is then asked, via the display means, whether he wishes to interact with this receiver device  2 . The user then acts on the control means to confirm or decline interaction. 
         [0044]    In a first variant of the invention, there could be a function with an additional identifier which is the device identifier. Indeed, it is possible to envisage portable object  3  being programmed to interact with only one receiver device  2 . Consequently, when the user wearing portable object  3  passes close to this particular receiver device  2 , portable object  3  interacts therewith, whereas when he passes in proximity to another device  2  of set  1 , no interaction occurs. 
         [0045]    In a second variant, it is possible to envisage that the identifier associated with the programmes or with the channel and programmed in watch  3 , is manually inputted by the user. The user can then select the desired identifier, via an application directly installed in portable object  3  or via an application installed in an object of the smart phone or touch tablet type. 
         [0046]    In a third variant, it is possible to envisage several identifiers associated with the programmes or channels being automatically or manually programmed in watch  3 . This multitude of identifiers is classified by order of preference. Portable object  3  then acts as follows. 
         [0047]    When portable object  3  is close to a receiver device  2  belonging to set of devices  1 , portable object  3  acts on this receiver device  2  by communicating the first identifier associated with programmes or with channels on the list. This interaction between portable object  3  and receiver device  2  results in a scan of the various frequencies of the electromagnetic signal to select the particular frequency on which a programme with the same identifier is being broadcast. 
         [0048]    However, if at that moment, there is no particular frequency on which a programme with the same identifier is being broadcast, then the portable object sends the second identifier on the list so that the receiver device scans the various frequencies in order to select the particular frequency on which a programme with the second identifier is being broadcast, and so on. The mode of operation is the same, so that if the channel of the first identifier is unavailable for any reason or not desired by the user, then it is the channel of the second identifier on the list that will be selected. 
         [0049]    A fourth variant provides for the resolution of different conflicts. Indeed, if several users with a portable object according to the invention are in proximity to a compatible receiver device, it is necessary to know which user takes priority in the selection of the particular frequency. 
         [0050]    To achieve this, a first method, seen in  FIG. 3 , consists in giving priority to the first user nearby. Receiver device  2  is configured in that case to block interactions with the other portable objects  3  via a blocking signal (S_BLOC). 
         [0051]    A second method for managing conflicts, seen in  FIG. 4 , consists in considering that users are not necessarily interested in having their preferred frequency automatically selected in the receiver devices. This second method thus consists in sending notification, via a signal (S_NOT), to all the users indicating that there is a conflict between them. This notification further includes a request for a response that the users must provide via a signal (S_REP) so that the first to respond to the notification will take priority over the others. Any interactions with the other portable objects are then blocked. 
         [0052]    Blocking may continue until the particular frequency is changed by a user via commands on the receiver device or via a remote control. It is also possible for blocking to continue whilst the portable object  3  which has priority is nearby. If the user of the portable object  3  that has priority moves, so that receiver device  2  and portable object  3  are out of range of each other, the blocking stops. 
         [0053]    In another variant, detection by portable object  3  of a compatible receiver device  2  may occur if said receiver device  2  is in standby mode, i.e. switched on but not active. Thus, when portable object  3  is close to a receiver device  2  belonging to set of devices  1 , the portable object acts on the receiver device by sending a command to exit standby mode and change into active mode, while communicating the identifier associated with the desired programmes or channels. 
         [0054]    It will be clear that various alterations and/or improvements evident to those skilled in the art may be made to the various embodiments of the invention described in this description without departing from the scope of the invention.
