Description

The invention relates to the field of devices and methods for broadcasting and receiving radio programs.

Context of the invention and problem posed The field of broadcasting of audio content is known since Marconi and the first public radio transmissions in 1906. The programs broadcast are usually composed of a mixture of pre-recorded sound tracks (musical recordings, recorded broadcasts). , games, advertising), and live broadcasts (debates, news, concerts, weather, road traffic, etc.).

Numerous improvements have been made to the existing devices, notably enabled by the introduction of digital technologies, the dissemination of content over the Internet, and memories installed within program receivers. Some of these improvements are intended, for example, to pause a radio program while listening, or to go back a few minutes, to listen to all or part of a particular passage. Document WO 99/37045 ("Interactive Digital Broadcasting System", 1998) of General Instrument Corporation also discloses a digital broadcasting system comprising various interactive properties, in particular the forward and return functions, according to a method enabling Moreover, the user, paying a subscription to access the service, to avoid all or part of the advertising messages to which the user does not pay is exposed.In a first embodiment, data is transmitted at a faster speed than in real-time mode, this data accumulates in a buffer of a receiver.The user can listen to a current track, move to the next track or return to previous tracks.

According to a second embodiment, at least two programming service streams received in real-time mode (ie user channels) are put in communication, so that a user can go directly from a track being played, at the beginning a track from another stream.

According to a third embodiment, levels of service levels are provided so that paying subscribers can avoid all or part of the advertising messages, while subscribers who do not pay can not avoid these advertisements. .

A replacement program may be transmitted on part of the bandwidth of the free service. Regarding the receiver, control data may be used with multimedia data to obtain a multimedia sequence identifying the properties of a track, such as the name of the artist, the title or lyrics of a song. Identification data may be communicated with the tracks to allow the user to skip the tracks he does not wish to listen to or to retrieve his favorite tracks on another programming service stream. This system uses several radiophonic streams transmitted simultaneously, so as to allow, as necessary, the receiver to jump from one stream to another to avoid certain contents characterized by predetermined tracers. It also comes close to audiophonic playlist. However, in the management of the advance and return keys, this system plans to move to the next or previous track "in the list" of memorized tracks, without specifying whether this list is complete or not with respect to a predetermined radio programming, it is that is to say that it does not deal with the case of a link that would only work intermittently for the transmission of the pieces from the transmitter to the receiver, with the consequence of the possible loss of pieces composing the planned programming.

OBJECTS OF THE INVENTION The object of the present invention is to propose a new mode of broadcasting and reception of radio streams, which answers the problem presented above. In particular, the invention aims, by providing "advance" and "return" functions, to allow navigation within a radio programming that is consistent with the creative choices of a radio station programmer, and even if the receiver does not have a permanent link with the station transmitting said program. The invention thus differs in particular from the concept of personalized radio, since it is not a question here of reconstructing and restoring a reading list according to the preferences of the user or resulting from a computer logic, but of allowing a navigation within a radio program effectively responding to an editorial will emanating from the person skilled in the art.

DISCLOSURE OF THE INVENTION To this end, the invention relates to a method for transmitting radio content sequences forming a pre-established programming (program schedule, musical programming, etc.), intended to be received by a set of remote receivers, by means of an optionally intermittent link, said method comprising steps for reforming at each receiver, independently of any losses of sequences linked to the link, a radio programming actually responding to the predefined editorial logic.

According to a preferred embodiment, the method of broadcasting and rendering of programs is implemented by a system comprising: at least one station transmitting a content stream in digital form, said content being organized in cycles of programs, each consisting of a series of N digital audio sequences, and developed according to the creative choice and editorial line of an antenna manager, who ensures that the sequences occupying the same position within the various cycles thus formed can possibly be interchanged with each other without distorting the editorial line that it wishes to impose for this radio program, - at least one receiver, implemented by a user of the system, comprising a random access memory, a user interface, and a means of data entry by the user. The method comprises steps in which: the station transmits in compressed form, at a speed faster than in real time mode, the programs made available by the antenna manager, the transmitted content stream includes, for each sequence, an identifier defining a passage order number If, corresponding to the position that this sequence must occupy in the planned order of the programming within the cycle to which it belongs, - the receiver receives not necessarily necessarily the signals transmitted by the transmitting station selected by the user, - the receiver is delivered with one or more cycles of pre-stored sequences, each consisting of a series of sequences according to the editorial line desired by the antenna manager these sequences being stored together with characterizing elements.

According to an advantageous implementation: - as soon as the user selects a transmitting station, his receiver reads successive sequences of a pre-stored cycle, - simultaneously with the return of said sequences, the receiver stores in memory, in a base of sequence data, the sequences of the programs that it receives from the transmitting station, each of said sequences having as recalling a passage order number Si defining its position within the cycle being received, - when the memory of the receiver is close to a predefined saturation threshold, the reception of a sequence Sk causes the deletion of a sequence of the same sequence number S'k according to a predefined method, for example that whose reception date is the older, - when listening to the program provides for the passage of a sequence bearing the number Si, and that several sequences are available at this number i, the receiver for This is primarily read by the sequence from the same cycle as the one just read. When this continuity is not possible, it selects one among those which it has in memory at number i according to a predefined method in advance, such as the one whose date of reception is the most recent, - a sequence of passage order number 1 is considered immediately following a sequence of passage order number N, - conversely, a sequence of order number N is considered immediately prior to a sequence of passage order number 1, when a sequence has been read by the receiver, it is indicated as such in the receiver's sequence database, the receiver also stores in memory the list of sequences which have just been returned to the user, so as to allow the implementation of a "return" function, - likewise, the receiver has at any time a sequence of sequences beyond the sequence being restored, allowing the implementation of an "advance" function. These sequences belong either to the same cycle as that of the sequence being restored, or they come from other cycles stored in memory, or a combination of both. In all cases, the programming reconstituted within the receiver from a sequence of "future" sequences is, by construction, necessarily in accordance with the editorial will of the antenna manager.

According to various advantageous arrangements possibly used in conjunction: the identifier of a sequence notably comprises a title of said sequence, an author or participant, keywords characterizing the nature of the sequence, as well as a duration indicator of the sequence, the identifier of a sequence is sent at the beginning of each sequence transmission, the identifiers of all the sequences comprising a programming cycle are sent at the beginning of each sequence transmission.

The method further comprises, in an advantageous embodiment, steps in which: - as and when the receiver renders the sequences constituting a program, all or part of their identification elements are displayed on a display screen of the receiver. - The information corresponding to a predetermined number of previously restored sequences on the one hand, and secondly scheduled to be restored in the subsequent programming, beyond the sequence being read, can also be displayed at the same time. screen to facilitate the implementation of the functions "return" and "advance".

According to various advantageous arrangements possibly used in conjunction: the user can decide at any time to note a sequence listened to on at least one evaluation criterion, according to a predefined rating scale, this note then being saved in the sequence database received. Advantageously, in this case, the sequences whose reception date is old, for example greater than a predetermined threshold, and / or which have already been read in whole or in part to the user, but which are not part of the sequences " preferred by the user according to the note assigned to them, are deleted from the sequence database in priority as they can be replaced by sequences of the same number of order of passage, newly received, - the receiver keeps in mind that a sequence has been at least partially read, and replaces as soon as possible and as a priority, as and when they are received, the sequences identified as having already been read and whose numbers order of passage are the most "distant" of the sequence being read, that is to say having a number of order of passage N / 2 (modulo N) of the passage order number of the current sequence for reading, the transmitting station transmits sequences representing a total playing time greater than the expected daily programming duration, so that at a given sequence number, the receiver 4 can store several alternative content sequences, the user can at any time actuate an "other" button, which has the effect of launching the broadcasting of an alternative sequence instead of the sequence being played, of the same order number of passage, when it exists, the receiver uses the notes already assigned to previous sequences to favor in a set of alternative sequences, the one that responds as closely as possible to the tastes of the user, these tastes being determined on the basis of the scores awarded and the qualifying elements received sequences.

Secondly, the invention relates to a computer program product comprising program code instructions for executing the steps of a method as set forth above, when said program is executed on a computer or a system. embedded system allowing the execution of such a sequence of software instructions.

BRIEF DESCRIPTION OF THE FIGURES The aims and advantages of the invention will be better understood on reading the description and the drawings of a particular embodiment, given by way of non-limiting example, and for which the drawings represent: FIG. 1: the various elements involved in the device and the method according to the invention.

DETAILED DESCRIPTION OF ONE EMBODIMENT OF THE INVENTION As seen in FIG. 1, the present invention finds its place in the context of a system for broadcasting and rendering radio programs.

Such a system comprises in the present example a transmitting station 1 comprising a coder 11 radio program type known per se, connected to a database 2 of sound programs (musical or spoken, including or not advertising), and possibly than at a facility 3 of content creation.

The broadcasting system according to the invention also comprises at least one receiver 4, implemented by a user of the system. Said receiver 4 is, in the present example, of a size comparable to the commercial radio receivers. It comprises in the first place a decoder 9 adapted to receive the digital signals broadcast by the transmitting station 1. The receiver 4 also comprises a controller 10, connected to the decoder 9. This controller is of microprocessor type, adapted to execute the instructions of a previously memorized program. The receiver furthermore comprises, also connected to the controller 10, a memory 5 (for example of the flash memory type), a read-only memory 8, in which is stored in particular a program capable of implementing a method for managing audio sequences according to FIG. 'invention. The receiver 4 furthermore comprises a visual interface 6, and a means 7 for inputting data by the user, connected to the controller 10, this visual interface 6 and this input means 7 possibly being merged in the form of a screen touch. It also comprises one or more speakers 12.

Mode of operation It is admitted that it is possible to associate to any radio programming a notion of cycle, composed of a variable number of N audio sequences, according to the type of radio, responding to a structure which is repeated in time. This cycle can, for example, be materialized by a program grid established over 24 hours, which defines the sequence of one or more programs that succeed each other on the air over successive time periods, and over a given period of time ( for example on weekdays, or weekends), each of these broadcasts then defining a sequence, in the terminology of this invention. In the case of musical programming, this cycle will be a priori much shorter than 24 hours to be composed of a sequence of only a few musical titles, or several hours of listening, as appropriate, and according to criteria emanating from a person skilled in the art who will introduce, for example, a novelty only all the nth titles, linking slow and faster pieces according to a particular sequencing to all these criteria (possibly modeled and memorizable under form of a series of rules of sequence of pieces according to elements characterizing these pieces: duration, type, rhythm, age, author etc., associated with each programming cycle) then defining the radio "format" of the musical programming considered , also organized in audio sequences. Of course, a radio can, in a general case, be broken down into several successive sub-cycles, representative of time slots during which, for example, there will be spoken programs, news bulletins, chronicles, debates, etc. These "spoken" beaches are themselves spaced by musical tracks answering formats (thus sub-cycles) possibly different.

In order to simplify the description thereof without limiting its scope, it will nonetheless be considered that a station according to the invention consists of an indefinite succession of the same main cycle of audio sequences, the programming of which is based on the creative choice of the person skilled in the art, for example of an antenna manager, on the basis of a theme, his personal tastes or any other event or cause according to the editorial line specific to the program in question. In the exercise of this programming, and in the very logic of the cycle, there is admitted a certain tolerance as to the interchangeability of sequences occupying the same position within different programming cycles - a "novelty" chosen to succeed a set of N "classic" titles that can for example replace the "novelty" planned in one place in another cycle.

Once a programming cycle thus composed, the transmitting station 1 transmits it by radio, satellite, internet network or any other means of dissemination known per se, in the form of a stream of audio content (composed of a suite organized sequences of audio content) to a remote audience.

The emitted sound content stream is of digital type, and comprises, for each sequence, an identifier defining a passage order number Si, corresponding to the position that this sequence must occupy in the order expected within the programming cycle. . The identifier of a sequence may also contain a title of said sequence, an author or participant, as well as various keywords characterizing the nature of the sequence. It preferably contains a duration indicator of the sequence, and may optionally contain a time slot and a tolerance around the limits of this range during which the sequence will be intended to be returned to the user. The insertion of this identifier in the header of each transmitted sequence is carried out by a method known to those skilled in the art. This stream of audio content is transmitted in compressed digital form, for example in MP3 type format, so that the content sequences forming a coherent programming cycle are received and stored by a receiver 4 much faster than they are. restored when listening by the user. Much faster is understood to mean that content sequences of a duration of a few minutes are typically received in a few seconds. It is understood that, in the case of transmission over the Internet, the sequences can be transmitted by different network nodes, and arrive at different or inverted times. The sequence number associated with each sequence then makes it possible to reconstitute the initial order of the sequences within the scheduled programming cycle to be returned to the listener.

In the present example, which is in no way limiting, the receiver 4 is delivered with several dozen hours of pre-stored audio sequences, organized in several cycles. Thus, as soon as the listener turns on his receiver 4, the latter is able to restore a cycle being received if the receiver is able to connect to the transmitting station 1, but can also restore sequences from pre-stored program cycles with which it was delivered, especially if the link with station 1 is interrupted, or reconstruct a cycle from a combination of both. In this case, the choice of a restitution of sequences resulting from a cycle being received, or from programs stored in memory, may for example be oriented by a measurement of the quality of the link detected by the receiver at the time of its start, according to a method known to those skilled in the art.

It is thus understood that even if the link between the transmitting station 1 and the receiver 4 has been interrupted, so that one or more sequences are identified as missing in a received programming cycle (no sequence received corresponding to a number given order between two sequence numbers for which the sequences were correctly received), then the receiver 4 is able to replace each missing sequence Si by one of the sequences Si; pre-stored (or stored when receiving other cycles) and having the same order number of passage, within the programming cycle being restored.

If, at the time when it is turned on, the receiver 4 has in memory of sequences Si whose one identifying element determines a broadcast time corresponding to this time, then the receiver 4 starts its restitution by these sequences, in the order provided by the programming. In the absence of such a time constraint, the receiver 4 starts its restitution by a sequence S + + N / 2 "distant" of N / 2 of the sequence number of the sequence S 1 being received (modulo N), if N denotes the total number of sequences composing an entire programming cycle. It is understood that the choice made here of a distance of N / 2 pieces can naturally be modified in a distance of N / 3 or any other value, nevertheless far from the sequences being received.

If, at the time of its start, the connection between the transmitting station 1 and the receiver 4 is interrupted, and if the receiver does not have a sequence Si to be restored to this time, then the receiver can start its restitution by any one of the Sk sequences which it has in memory. A choice can nevertheless be oriented by different criteria, for example to start with the first sequence of the longest sequence which it has in memory of the sequences identified as belonging to the same programming cycle, or to start with the first sequence of last cycle received.

It is understood that, in this way, the user thus has, at any time, the ability to be able to "skip" a sequence Sk of a cycle C being restored in order to proceed to the next sequence Sk + 1, or to a sequence S'k + 1 from another cycle C 'if the sequence Sk + 1 is absent, but in any case according to an ordered sequence according to the editorial will desired by those skilled in the art . This faculty is exercised through an interface known per se, such as pressing an "advance" button available on the receiver. Similarly, the receiver stores in a database the identifiers of recently restored sequences, corresponding to the Sk sequences that have just been actually listened to in whole or in part by the user, in order to offer him the faculty of "backtracking" in programming, for example by pressing a "return" key. In an implementation variant, one or more identification elements of the sequences Si (number, title, author, duration) are displayed on a display screen 6 of the receiver 4. A predetermined maximum number of sequences, for example ten , is displayed, so as to simplify the reading by the user. The screen 6 may however propose icons "next page", "previous page", of known type, if the user wants to access all the sequences already restored, or constituting the future programming, so as to facilitate the navigation by the listener.

When a sequence Sk has been restored by the receiver 4 to the user, it is reported as such in the sequence database of said receiver. It is also possible to provide for the saving of notes given by the user to the Sk sequences that he has listened to according to a predefined rating scale. These notes are then saved in the database of restored sequences, or in an associated database. Even if it is known that the size of the memories and the audio compression technologies allow today to store hundreds of hours of listening audio contents, it is understood that in normal operation the receiver 4 can be brought to receive and to consecutively store several cycles of content sequences as it restores a single one according to the predetermined order of passage, and that this sequence would naturally lead to the possibility of a saturation of the RAM 5, and this, even when the link with the transmitting station 1 only operates intermittently. In order to avoid this eventuality, an internal monitoring device at the receiver 4, for example managed by the controller 10, regularly checks the filling level of the random access memory 5 in order to provoke, if necessary, the suppression of certain Si sequences to allow them to be replaced. by new received sequences S '; according to a predefined method in advance, such as for example the deletion of the sequence Si whose reception date is the oldest, for its replacement by the sequence S' ;. In an implementation variant, the deletion of a sequence S1 stored in memory, with a view to its replacement, is established on the basis of a pre-established priority level, for example by its identifier, by having already been listened one or more times, by the passing of a certain date, by the note that it has possibly received from the user during a previous restitution, or by a combination of several criteria. In order to maximize the number of possible "backtracks" in the programming being listened to, and also to avoid instabilities in the implementation of the "jump (s)" function, the replacement device described above replaces in priority the titles "distant" of N / 2 (or (N + 1) / 2 if N is odd) of the sequence number of the sequence being listened to (modulo N), if N denotes the total number of sequences composing an entire programming cycle. Advantages of the invention It is understood that the method, as explained, allows a user, when listening to a program on a suitable radio, to advance in time within the radio program, and, typically, to skip one or more pieces of music that do not please him, within a programming meeting the editorial logic of the skilled person. This defines an operational system of anticipatory radio. The method uses the broadcast by a broadcaster of a stream of content sequences, for example in MP3 compression, the storage within a radio receiver of this content stream, and the playback of a programming cycle from stored sequences. The method involves the interposition, at the level of the transmitting station 1, after the creation of a programming, a device for the broadcast of sequences in compressed form, with order numbers and other identifiers. It also involves the use of a radio reception apparatus, in particular provided with data storage means and a programmable controller. In this case, the method is implemented in the form of a program for managing the received or planned content sequences, the management of the display and the user interface.

Variations of the Invention The scope of the present invention is not limited to the details of the above embodiments considered by way of example, but extends instead to modifications within the scope of those skilled in the art. . A first variant of the service is thus interested in radios whose programming is framed by fixed time slots. For these radios, a "jump" in user-initiated programming might not result in the return of a sequence of next-pass order numbers, but the reproduction of a sequence in a rotation in the list of sequences stored in memory and scheduled to be restored during the time slot considered, according to the information contained in their identifier. In order to respect a possible time constraint of end of emission, the restitution of the following sequence would not start at its beginning, but at a moment making it possible to make coincide the end of its restitution with the scheduled end time of the program. This jump could, for example, be triggered by pressing an "other" key. We then measure that the implementation of this variant of the device opens up new perspectives in radio, since it allows the person skilled in the art to offer his listeners, according to an editorial choice that it will have predetermined, a certain flexibility between several alternative sequences, during a radio appointment whose schedule is actually established and known in advance through the program schedule.

In the case of links that are known to be robust between the transmitting station and the receivers, which are therefore not exposed to interruptions, it is also possible to imagine "direct" beaches with periods of time during which the device is made active, in its main operation, or one of the variants.

Furthermore, the receiver is likely by design to have several programming cycles at any time in its memory, and therefore, when listening to the programming provides for the passage of a sequence bearing the number i, to have several sequences If, S ', S ", etc. from several different cycles By construction still, the receiver can propose one at random, since the sequences are ordered within each cycle with some tolerance to interchangeability between them, for the same order number of passage.

Other mechanisms could nevertheless be implemented. In a subvariant, the controller 10 could for example use the notes already assigned by the user to previous sequences to privilege in this set of alternative sequences, one that best meets the tastes of the user. These tastes are determined by the ratings and qualifying elements of the sequences received, eg author, style, year, type etc. In one of the possible implementations for this evaluation of a given sequence, the controller determines for each value of each qualifier attribute an average score received during the previous broadcasts, and calculates a weighted score of each alternative according to its attributes. The sequence
