Definitions
- the present invention relates to radio sets with digital data receivers, in particular of the RDS type.
- Radio sets marketed today - including car radios - have RDS receivers, which process data carried by RDS signals to display messages on a screen that includes the station (for example information messages to motorists on motorways) or to automatically adjust the reception of the station on the frequencies locally offering the best listening reception.
- the invention proposes an improvement which makes it possible to envisage numerous new applications for RDS broadcasting.
- a radio set with a digital receiver for example of the RDS type, a transmitter for transmitting digital information, such as for example, but not limited to a mobile phone,
- a unit for processing information carried by the RDS signals received by the radio station which is connected on the one hand to the radio station and on the other hand to the transmitter, selection means operable by an operator, these means also being connected to the processing unit, the processing unit receiving, by RDS signals, an identification code of the sequence broadcast by the radio and commanding station, when the selection means are actuated, the transmission of this code by the transmitter, with a user identification code, intended for a command centralization unit.
- a user can, by a simple actuation of the selection means, order from a purchasing center the compact discs, cassettes or the like which correspond to the audio sequence which is broadcast by a radio station or even respond to advertisements by this station (in order to obtain a catalog, or more information on the product) or to order the products which are the subject of an advertisement.
- the invention also relates to an electronic module characterized in that it comprises the processing unit and the means for selecting an assembly of the aforementioned type, as well as connection means for connecting the processing unit to the station. radio and transmitter.
- control system characterized in that it comprises a unit for transmitting signals, for example of the RDS type, which carry codes for identifying the sequences broadcast by a radio station, a plurality of assemblies of the type aforementioned and a command centralization station which comprises means for processing the codes that said station receives from the mobile telephones of the various assemblies.
- signals for example of the RDS type, which carry codes for identifying the sequences broadcast by a radio station, a plurality of assemblies of the type aforementioned and a command centralization station which comprises means for processing the codes that said station receives from the mobile telephones of the various assemblies.
- FIG. 1 is a schematic representation of an assembly according to a possible embodiment of one invention
- FIG. 2 is a schematic representation of a purchase order system according to the invention.
- the assembly illustrated in FIG. 1 comprises a radio station 1 with an RDS receiver, a processing module 2 to which the station 1 transmits RDS data which it receives, as well as a mobile telephone 3 of GSM type which is connected to the module 2.
- the module 2 is in the form of a box which contains processing electronics and which also has connection means for its connection to the radio set 1 or to the mobile telephone 3.
- the GSM could be a module integrated into the box, the assembly could then appear in a single box.
- the module 2 comprises a buffer memory 5 which is connected to the RDS receiver of the radio station 1 via a three-wire link consisting of a wire connected to ground, a wire which transports the RDS data and another wire carrying a RDS data synchronization signal.
- the means of dialogue with the user could be several buttons and an alphanumeric display.
- the microcontroller 4 is connected by a serial port 10 to the mobile telephone 3.
- the microcontroller 4 includes ROM memories on which are stored the RDS data processing software, as well as the communication software with the station 1 and mobile phone 3, RAM memories for the storage of the received RDS data, EEPROM memories for the storage of permanent data relating to the user (user code in particular).
- the module 2 allows a user, by a simple action on the selection button 8, to transmit to a central purchasing office, via his mobile telephone 3, an order order relating to the disc or to an advertisement which is broadcast by the radio station it is listening to.
- the RDS signals which are demodulated by the receiver of station 1 carry, in addition to the codes which correspond to conventional RDS applications and which are intended to be processed by the receiver of the radio set, a code for identifying the sequence audio broadcast by the station on which station 1 is tuned.
- RDS signals carrying an identification code are broadcast, as illustrated in FIG. 2, by the radio transmission stations 5.
- these stations 5 are for example equipped with bar code readers for reading the codes with which the material supports of these recordings are provided and the bar codes thus read are integrated into the RDS signals transmitted by the stations.
- RDS signal broadcasting systems are in themselves conventionally known and will not be described here.
- an RDS signal is a synchronous signal organized in contiguous groups of 104 bits. Each group is subdivided into 4 blocks of 26 bits which contain 16 bits of information and 10 control bits.
- Control bits serve two functions: detecting and correcting errors in transmission and synchronizing blocks.
- the microcontroller 4 calculates the control bits for each possible start of block and compares them with the bits received until a match is found. It then checks all the blocks to:
- the first two blocks of each group of the RDS signal always contain the same information: the type of application program and the type of group to which the group corresponds.
- the code of a product is issued on 32 bits, i.e.
- This broadcast allows a capacity of 22.8 digits per second to transmit 13-digit product codes, or 1.75 product identification codes per second.
- the information transmitted may contain, in addition to product codes, messages which could be written on a display, the transmission then taking place in an adequate format.
- the microcontroller 4 detects groups of the type
- product identification code stores the codes carried by these groups in its RAM memories for the purpose of issuing an order by the mobile telephone 3.
- the transmission of said code by a radio station 5 continues throughout the duration of the purchase window and as soon as it s 'stops, the identification code disappears from memory.
- the microcontroller 4 can automatically erase the product identification code after a predetermined time.
- the microcontroller 4 verifies the presence in its RAM memories of a correct product identification code.
- the microcontroller 4 prepares a message to be sent to the mobile telephone 3, then transmits it to it.
- the mobile telephone 3 then automatically dials the number of the central purchasing office (CA in FIG. 2) where orders are centralized and transmits it, for example via a modem link or the SMS service (short message service, accessible on most mobile phones), the information required to register the order (product code and user identification number).
- CA central purchasing office
- SMS service short message service, accessible on most mobile phones
- the centralization station of the central purchasing office CA includes means for automatically processing the codes that said station receives. Orders are then transmitted by the central purchasing office to producers or advertisers (PA in Figure 2) who deliver the products ordered to users of the ordering system.
- producers or advertisers PA in Figure 2
- the microcontroller 4 detects errors in use, and in particular repeated commands for the same product at short intervals.
- the microcontroller 4 When the purchase order has been correctly sent, it commands the microcontroller 4 to emit an audible signal indicating that the order has been sent.
- the microcontroller 4 automatically detects its connection, via the serial port 10, to a programming terminal. When such a connection is detected, it controls the emission of a signal, for example sound or light.
- Such a programming terminal is used to transmit to the EEPROM memories of the microcontroller
- DAB Digital Audio Broadcasting
- the transmitter could be integrated into module 2.
