Description

Field of the invention

  The present invention relates to a radio device in particular for a motor vehicle comprising an installation for recognizing musical pieces received and a title memory unit making it possible to record a title.

  The invention also relates to a method for controlling a radio device comprising a memory unit in which titles with an attribute are recorded.

  STATE OF THE ART Radio systems are known which transmit a musical piece with a title to inform the listener. It is also known to transmit a type of program informing the user of the nature of the program transmitted by the radio transmitter.

  According to document DE 199 57 926 AI, a radio station 15 is known which is equipped with a control button, the actuation of which enables the musical piece (song) to be loaded by radio link during the passage.

  The document WO 95/28803 describes a radio receiver which stores the title of the song played with the time, the date and the transmitter, to allow the transmitter to recover the audio data later. OBJECT OF THE INVENTION Starting from this known state of the art, the present invention aims to develop a radio apparatus and a method for controlling such a radio apparatus allowing a listener (user) to simply compose a global program, optimum, corresponding to his wish to listen from transmitters likely to be received.

  Description and advantages of the invention To this end, the invention relates to a radio device of the type defined above, characterized in that it comprises at least one reception device monitoring a large number of radio transmitters capable of be received, with an installation of characteristics provided for characterizing the titles stored with an attribute and an automatic switching unit which changes the transmitter set if the title reproduced has a negative attribute in the title memory unit, or even switches to a transmitter 35 which transmits a title having a positive attribute in the title memory unit.

  The invention also relates to a method for controlling a radio device of the type defined above, characterized in that the title of the received song sent by the set transmitter is compared with the titles stored in memory and in the event of recognized agreement of the title and a negative attribute you automatically change the set transmitter or you play a song title in memory.

  The invention also relates to a method of the type defined above, characterized in that the title of a musical piece received from a transmitter not adjusted is compared to the title stored and in the event of recognized association of the title with a positive attribute, the set transmitter is changed, automatically to switch to the transmitter of the musical 1o piece having a positive attribute.

  The radio device according to the invention comprises at least one reception device which monitors a large number of radio transmitters capable of being received and an installation of characteristics makes it possible to characterize the title stored in memory with an attribute and a communication unit. automatic mutation which changes the transmitter set when the reproduced title has a negative attribute in the title memory unit. As a variant, one switches to a transmitter if a title provided with a positive attribute is recognized in another transmitter and if according to one embodiment, at this time, the adjusted transmitter does not reproduce any title having a positive attribute.

  According to a development of the invention, there is provided an installation for reading the stored sound signals, this installation being able to be activated by the switching unit for reproducing the sound signals stored for example from a CD or cassette 25 if none of the issuers received issues a security with a positive attribute.

  Advantageously, the radio apparatus processes digital radio signals making it possible to transmit additional information in a particularly simple manner so that it is easier to recognize specific titles, performers or musical directions or types of programs. .

  Advantageously, the radio device comprises two reception devices among which the first is designed to reproduce the signals received and the second reception device monitors the radio transmission of the transmitters capable of being received, in the background and in the path of the corresponding signals. to the switching installation indicating whether musical pieces with positive or negative attributes are received from transmitters other than the transmitter set up to allow the reproduction of these signals.

  A method of controlling a radio device makes it possible to compare the title of the musical piece received from the tuned transmitter with titles stored in memory and that in the event of a recognized association between the title and a negative attribute, it changes automatically from transmitter 5 or a musical title played in memory is played. Under these conditions, if a tuned transmitter transmits a musical piece recognized as having a negative attribute, this piece is immediately cut to be replaced by another musical title coming either from a data medium, for example from a CD disc , or a musical title recorded in memory 10 or also a musical title received from another transmitter. There is thus an automatic transmitter switching according to the attributes of the musical song title received from the transmitter on which the radio device is tuned.

  A development of the method provides for playing the track musi15 cal in memory until a track having a positive attribute originating from one of the transmitters capable of being received can be entered and then we switch to this transmitter and reproduce the musical piece with a positive attribute. This means that only when a musical piece having a positive attribute is received, it switches back to radio mode, while otherwise the reproduction of the musical title or titles stored is retained.

  A variant method of controlling a radio device provides for comparing the title of a musical piece received from an unregulated transmitter and the titles in memory, and that in the event of a recognized concor25 dance for the title with a positive attribute of the set transmitter, you automatically switch to the transmitter of the musical piece with positive attribute. The musical piece with positive attribute is then played so that only musical pieces with a positive attribute will be played automatically.

  A development of the method provides that the change of transmitter will only take place if a musical piece has been played until the end so as not to change the transmitter in the middle of a piece which may also have a positive attribute if necessary. . Conversely, it is also possible to exclude musical pieces from performers selected after selection by the user to exclude them from reproduction.

  A development of the invention provides for entering the attribute as well as the interpreter and automatically switching to a transmitter transmitting the musical piece of this performer, which depends on whether additional information, in addition to the musical piece, has has been transmitted, indicating the performer for this musical piece.

  Advantageously, different priorities are assigned to titles and when a high priority title is received, it is immediately executed if the transmitter to which one is tuned sends a musical piece of lower priority.

  Drawings The present invention will be described below in more detail with the aid of exemplary embodiments represented in the appended drawings in which: - Figure 1 is a diagram of a radio apparatus, - Figure 2 is a flow chart of the monitoring of a transmitter, - Figure 3 is a flow chart of the control method, - Figure 4 is a flow chart of a switching decision. Description of embodiments of the invention FIG. 1 schematically shows a radio device 1 connected to a display 3 and a device 2 for reproducing the recorded musical piece, for example a CD disc player. An antenna 14 is also provided for receiving radio signals from transmitters SI, S2. The received radio signals are emitted by a loudspeaker 15 after being amplified in an appropriate manner.

  The radio device 1 includes a memory unit 13 for recording song titles (musical pieces) and the titles are associated with an attribute indicating whether it is a desired song or not desired by the user.

  A control unit 4 comprises keys 41, 42, 43 comprising a selection key 41, a locking key 42 and a special key 43 for introducing a preferential piece. In place of the special key 43 for the preferential song, this function can also be performed by pressing and holding the selection key 4 1.

  The radio 1 further comprises two reception devices 11, 12 which appropriately convert the signal received by the antenna; the first reception device 11 corresponds to the transmitter 35 on which one is set.

  Figure 2 shows the monitoring and selection operations of different transmitters; in step 2, the second reception device 12 monitors the signals coming from the transmitters Si, S2 and asks if a start of the musical piece has been detected in step 20. If this is the case, in step 21 we ask if such a song is recorded in memory 13 and if for example it has not been played during the last hour. Preferably, account 5 also is taken of the emission 5 from the CD disc player 2. If this title of musical piece was emitted in a preselected period (here this period corresponds to one hour) or if there is no has not been stored in a memory, the next transmitter capable of being received in step 23 is checked. If the title is in the memory or if it has not been previously transmitted during a predetermined period, then in step 22, it is checked whether one of the musical pieces in memory has been emitted. If this is not the case, it is set to the transmitter which reproduces the recorded musical piece, with a positive attribute using the reception device 11 and this musical piece is emitted by the speaker 15. If this is not the case 15 and if the blocking key 42 has been pressed, the latter prohibiting the automatic change of transmitter, then there will be no change of transmitter and it remains set to the same transmitter.

  To associate an attribute with a title of a musical piece, the control unit 4 is also used; during the transmission of a musical score, the user of the radio 1 gives the title of the musical piece being executed an attribute by pressing the key 41 and saves this attribute. The attribute can be positive or negative so that after having associated an attribute with a title, in the future an unwanted title will be eliminated and on the other hand a preferential title will be determined on another issuer 25 for the moment not settled and the title will be reproduced preferentially. Thus, after a learning phase, the user will obtain that the radio preferably plays tracks (musical pieces) that the user (listener) likes to listen to. Under these conditions, it is not necessary to have large memory to record the whole of a musical piece because it suffices to store the title of the song in memory. This is particularly advantageous for mobile devices.

  It also eliminates the transmission of additional data to a transmission installation or the provision of an appropriate sound medium. It also avoids the switching or the periodic change of transmitter with the sole purpose of hearing the end of a musical piece classified as positive as well as the selection between different transmitters having a similar musical program and which as transmitter by installments offers a program composition directed precisely towards a goal. Precisely in regions where the user does not know the different transmitters, he can, thanks to the device and method of the invention, compose a musical offer corresponding to his taste.

  Advantageously, a large number of song titles can be recorded, which makes it possible to establish a wide and varied musical program. A title recorded in memory and assigned a positive attribute will generally only be played towards the end until a change of transmitter. Likewise, certain titles may have a higher priority 10 so that the execution function can be interrupted until the end and a title with a very high priority will always be played when it is issued by a transmitter which may be received. To avoid inevitable repetitions, a repetition barrier can be set so that the same title is not played without interruption and the duration of the repetition barrier is preferably predefined by the user; in the state of first installation of the device, this duration corresponds for example to one hour. Additional priorities can also be assigned to certain programs such as sports or traffic announcements.

  The transmitter once set remains set according to its first embodiment until on another transmitter, one of the titles recorded in memory is recorded with a positive attribute. If the transmission of such a song title ends, you can choose the function of playing the musical song from a CD, MP3 player, cassette or mini-disc until the start of a new song recorded with a positive attribute appearing on the monitored transmitter, which can be received. The music recorded in memory thus serves as filling music between two preferential songs sent by the radio.

  One development plans to register for the different users each time their own user profile to open each radio user a different selection of titles.

  The radio device is advantageously a car radio and it can receive by two reception devices 11, 12, a piece of music in the form of audio data in connection with additional data concerning the title or the performers. This additional information, that is to say the title of the song or the performer, can also be transmitted in a coded manner by associating for example certain codes with a combination of musical pieces and performers.

  The title and the performer as well as the set transmitter are preferably displayed on a display 3 and they are recorded in the memory unit 13 using an appropriate selection key 41, 43. The memory 13 is preferably designed as a FIFO (first in first out) memory.

  You can also enter the instant of the last transmission of a song title in memory and within the framework of a fixed period, if this title is not replayed, you can erase it from memory. Another development of the invention provides for manually entering the titles of the songs or from a remote central via a radio interface. It is for example possible to transmit over the Internet, a hit parade provided by a service provider by updating it regularly. Such a list can also be established by the user himself on his PC and be transmitted to the vehicle.

  Besides songs that the listener or user particularly likes to hear, there are also musical pieces that do not please the user so that he has an alternative realization allowing to eliminate the reproduction of such a song if this unwanted song receives a negative attribute. By actuating an appropriate control element, the musical piece is recorded with a negative attribute. The radio then preferably switches automatically to another transmitter which is preferably part of the same type of program so as to reproduce the same musical direction or the same type of program in the car radio. According to the actuation of the control element, a state of emission is associated with a musical piece, namely "play preferentially" "delete" or "continue".

  Based on a positive list, a list is created with a large number of musical pieces that the listener or user no longer wishes to hear. This list can also be associated in a personalized way with users. It is also possible to exclude all the songs from one or more performers to avoid their reproduction.

  Figure 3 shows a flowchart for entering a negative attribute. In step 30 a musical song title 35 is reproduced on the radio 1 and in step 31 a question is asked whether a corresponding key has been pressed to associate a negative attribute with the musical song. If this is not the case, the musical title is reproduced as returning to step 30. If however there is a negative attribute, this is stored in memory in step 32; in step 33, change the transmitter or switch to a reproduction of a CD or other sound medium. The entry ends with stage 34.

  Figure 4 shows the reproduction routine. According to this, in step 35, the start of a new musical piece is detected. The musical piece that begins is compared to the musical pieces in the list according to step 36. If the title is recorded with a negative attribute, the transmitter will be changed in step 37; if the musical piece is not recorded with a negative attribute, it will be transmitted in step 38. This avoids the radio transmission of musical pieces not desired by the user.
