AN AUDIO AND / OR VISUAL SEQUENCE, TERMINAL AND (o4J METHOD OF RETURN OF AT LEAST ASSOCIATED SYSTEM.

FR 3 063 157 - A1 yv) The invention relates to a method for reproducing at least one audio and / or visual sequence, the method comprising the following steps:

obtaining (S300) a geographic area in which a terminal (100) is positioned, obtaining (S302) at least one sequence associated with said geographic area, rendering (S304), by means of said terminal, of said at least one sequence associated with said geographic area.

Invention background

The present invention relates to the field of rendering audiovisual sequences by means of mobile terminals, and more particularly relates to a method of rendering at least one audio and / or visual sequence.

During events (for example sporting, musical, social, etc.), speakers such as sportsmen or artists interact very frequently with the public. The most common interactions are exchanges of words or songs.

Spectators can also carry signs or banners, or create a large-scale motif or visual animation ("tifos") using a plurality of supports such as sheets or balloons.

These various visual supports have the drawback of being static in terms of colors and shapes, which limits the possibilities of interaction. In addition, the creation of supports and the organization of tifos are quite tedious, and the supports become waste once the event is over.

Spectators of a concert can also use a software application for mobile terminals, this application being able to analyze the sound captured by the microphone of the terminal and to propose a display of colors on the screen of the terminal according to the analysis. Each spectator using the application on their mobile phone can then hold their phone so that the screen is visible from the stage by the musician.

However, control of the display using this application is limited, since the application only takes into account the sound environment of the mobile terminal.

Subject and summary of the invention

The present invention relates to a method for rendering at least one audio and / or visual sequence, the method comprising the following steps:

• obtaining a geographic area in which a terminal is positioned, • obtaining at least one sequence associated with said geographic area, • restitution, by means of said terminal, of said at least one sequence associated with said geographic area.

The invention therefore proposes to associate at least one sequence with at least one geographic area, so that when a terminal is located in the geographic area, the latter can reproduce the sequence.

Taking into account the geographic position of the terminal makes it possible to increase control over the restitution of the sequence.

Indeed, this taking into account allows for example to several different terminals, positioned at different locations, to transmit different sequences. It also allows a single terminal to transmit several sequences according to successive geographic positions of the terminal. It is thus possible to determine in advance a scenario comprising several sequences, so as to create a pattern, an animation, and / or a global piece according to the position of one or more terminals.

The invention thus makes it possible to precisely control the rendering of scenarios.

The restitution of the sequence by means of the terminal also makes it possible to use a widely used object as a support, without this producing waste.

In addition, the audiovisual capabilities of the terminal make it possible to improve the rendering of the restored sequence. For example, the brightness of a terminal screen allows visibility of the sequence displayed in the dark, and the screen can display a multitude of colors.

In a particular embodiment, said at least one sequence is also associated with at least one starting condition, said at least one sequence being restored when said at least one starting condition is verified.

The starting condition makes it possible to synchronize the restitution of the sequences, in order to create a coordinated and coherent rendering of the scenario. A large number of terminals (for example several thousand) can then play back one or more sequences in a synchronized manner.

In a particular embodiment, said at least one starting condition is a temporal starting point determined by taking into account a reference clock.

The determination of the time starting point taking into account a reference clock allows synchronization of all the terminals implementing the rendering process. Indeed, all the terminals can then take into account the same reference clock. Thus, the sequences can be reproduced in a synchronized manner by the terminals, so that the overall rendering of the restored sequences is precise and consistent.

In a particular embodiment, said at least one sequence comprises:

• at least one image associated with a duration of restitution, and / or • at least one sound associated with a duration of restitution.

In a particular embodiment, the position of the terminal is obtained:

• from data entered by a user of the terminal, • by means of a GPS receiver of the terminal, and / or • from data received from an external device.

In a particular embodiment, a plurality of sequences is obtained in the step of obtaining at least one sequence, each sequence being associated with a different predetermined position, the set of sequences forming at least one scenario.

In a particular embodiment, a plurality of different scenarios is obtained in the step of obtaining at least one sequence, each scenario comprising at least one sequence, the method further comprising a step of selecting a scenario in function of at least one parameter relating to at least one detected position, said at least one parameter relating to at least one detected position being:

• a number of position (s) of at least one detected terminal (s), • a density of position (s) of at least one detected terminal (s), and / or • a precision of position (s) d 'at least one terminal detected.

Thus, the method can be adapted to the number of terminals implementing it, to the distribution of these terminals, and / or to the accuracy of the geolocation of these terminals. Thus, if the spectators are few, a simple scenario can be selected so that the rendering of the scenario is understandable. In addition, if the place of the event is not filled uniformly, a scenario taking into account this lack of uniformity can be chosen, so that the rendering of the scenario is understandable.

Position accuracy can be used in combination with position density. Indeed, the more the spectators are numerous, the less the precision is important. A broad motif or a wave (conventionally called “ola”, that is to say “wave” in Spanish) can then be selected as scenario.

The invention further relates to a telecommunications terminal, capable of implementing a restitution method as described above.

In a particular embodiment, the different stages of the restitution method according to the invention are determined by instructions from computer programs.

Consequently, the invention also relates to a computer program, on an information medium, this program comprising instructions adapted to the implementation of the steps of a restitution method according to the invention.

This program can use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

The invention also relates to an information medium readable by a computer, and comprising instructions of a computer program as mentioned above.

The information medium can be any entity or device capable of storing the program. For example, the support may include a storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM, or also a magnetic recording means, for example a hard disk.

On the other hand, the information medium can be a transmissible medium such as an electrical or optical signal, which can be routed via an electrical or optical cable, by radio or by other means. The program according to the invention can in particular be downloaded from a network of the Internet type.

Alternatively, the information medium can be an integrated circuit in which the program is incorporated, the circuit being adapted to execute or to be used in the execution of the process in question.

In addition, the invention relates to a system capable of implementing a restitution method as described above, the system comprising at least one telecommunications terminal.

Detailed description of several embodiments

FIG. 1 represents, diagrammatically, a telecommunications terminal 100, capable of implementing a method for reproducing at least one audio and / or visual sequence, according to an exemplary embodiment of the invention.

No limitation is attached to the nature of the terminal 100, nor to the telecommunications network (s) that can be used by the terminal 100 to communicate. Thus, the terminal 100 can be for example a mobile or portable terminal such as a telephone (for example of the “smartphone” type) or a portable computer, a digital tablet, etc.

For the sake of simplification, in the example illustrated in FIG. 1, a single terminal 100 is envisaged. However, as described below, the invention also applies to a system comprising a plurality of terminals or a system comprising a server and one or more terminals.

The terminal 100 includes a first obtaining module 102, a second obtaining module 104 and a rendering module 106. In addition, the terminal 100 can comprise a verification module 108 and / or a selection module 110.

The playback module 106 may include a screen capable of rendering an image or a video, a light-emitting diode, and / or a loudspeaker capable of rendering one or more sounds.

In addition, the verification module 108 may include a camera capable of capturing an image or a video, a microphone capable of capturing one or more sounds, and / or an accelerometer capable of measuring the movements of the terminal 100.

A software application or a web page can include one or more of these modules 102, 104, 106, 108, 110.

As shown in FIG. 2, the terminal 100 presents the conventional architecture of a computer. The terminal 100 notably includes a processor 200, a read only memory 202 (of “ROM” type), a rewritable non-volatile memory 204 (of “EEPROM” or “Flash NAND” type for example), a volatile rewritable memory 206 (of type "RAM"), and a communication interface 208.

The read-only memory 202 of the terminal 100 constitutes a recording medium conforming to an exemplary embodiment of the invention, readable by the processor 200 and on which a computer program P1 conforming to an exemplary embodiment can be recorded. realization of the invention. As a variant, the computer program P1 is stored in the rewritable non-volatile memory 204 or in the volatile rewritable memory 206.

This computer program P1 defines functional modules and software here, configured to implement the steps of a restitution method in accordance with an exemplary embodiment of the invention. These functional modules rely on or control the hardware elements 200, 202, 204, 206 and 208 of the terminal 100 mentioned above. They notably include here, as illustrated in FIG. 1, the first obtaining module 102, the second obtaining module 104, the restitution module 106, the verification module 108 and / or the selection module 110.

The functions of these different modules are described in more detail below, with reference to the steps of the methods described with reference to FIGS. 3 and 4.

FIG. 3 represents a method for restitution of at least one audio and / or visual sequence, according to an exemplary embodiment of the invention.

In the following description of FIG. 3, it is considered that the restitution method is implemented by the terminal 100 of FIG. 1. However, the method can be implemented by any system comprising at least one terminal.

In a step S300, a geographical area in which the terminal 100 is positioned is obtained by the first obtaining module 102.

In addition, in a step S302, the second obtaining module 104 obtains at least one sequence associated with the geographical area.

The sequence (s) obtained, associated with the geographical area, is (are) restored in step S304, by means of the rendering module 106 of the terminal 100.

FIG. 4 represents a method of restitution of at least one audio and / or visual sequence, according to another exemplary embodiment of the invention.

In the following description of FIG. 4, it is considered that the restitution method is implemented by the terminal 100 of FIG. 1. However, the restitution method described below can be implemented by any system comprising at least one terminal.

In a step S302, at least one sequence associated with at least one predetermined geographic area is obtained by the second obtaining module 104.

In practice, according to exemplary embodiments, such an audio / visual sequence may include: at least one image associated with a duration of restitution; and / or at least one sound associated with a duration of restitution; and / or at least one light or “flash” flash also associated with a restitution period. In addition, such a restitution period can be finite or indefinite.

The geographical area can correspond to a part of a place, typically a place of event manifestation.

A sequence can be associated with one or more predetermined geographic areas. In addition, a predetermined geographic area can be associated with one or more sequences.

In one example, a plurality of sequences is obtained in the obtaining step S302, each sequence being associated with a different predetermined position, and the set of sequences forming at least one scenario.

One or more scenarios can thus be obtained, each scenario comprising one or more sequences.

A sequence comprises for example a monochrome image, the duration of restitution of the image being typically of several seconds or minutes. As a variant, the sequence comprises a video, a sound or a piece of music.

A scenario can thus include one or more monochrome images, each monochrome image being typically associated with a different predetermined geographic area and typically associated with the same duration of restitution. Once restored, the monochrome images can represent a pattern visible by a speaker located for example on a stage, and / or by a camera filming the spectators, such as the pattern represented in FIG. 5, during the duration of restitution.

Each sequence can also be associated with one or more starting conditions.

The starting condition can be:

• a temporal starting point obtained by means of a clock of the terminal 100, • a predetermined sound, • a predetermined movement of the terminal 100, • a predetermined image, and / or • the reception of a message.

In a step S300, the first obtaining module 102 obtains a geographical area in which the terminal 100 is positioned.

The step S300 for obtaining is for example implemented after the opening of an application or of a web page, as mentioned with reference to FIG. 1.

Step S300 may include a sub-step S406 for obtaining the geographical position of the terminal 100.

In one example, the geographic position is obtained from data entered by a user of the terminal 100, typically by means of a man / machine interface of the terminal 100 such as a touch screen or a keyboard.

The data entered can for example correspond to a seat number of the place of the event, for example a seat number of a performance hall or a stadium.

In another example, the geographic position is obtained by means of a GPS receiver of the terminal 100. The geographic position is then given by the GPS coordinates of the terminal 100. The geographic position is then determined fairly precisely, the precision being the order of a few tens of centimeters, for example fifty centimeters.

In another example, the geographic position is obtained from data received from an external device.

One or more so-called external devices are then placed in the location of the event, so that each device covers a specific geographical area of the location of the event, and different from those covered by the other devices. By the expression "each device covers a geographical area" is meant that a device considered is capable of exchanging, in the area where it is located, data with another device such as the terminal 100, in particular by means of a short range telecommunication link. Each external device can for example be positioned under a different seat of the stadium or the performance hall.

The message or messages exchanged between an external device and the terminal 100 allow the terminal 100 to obtain the geographical position of the aforementioned external device, and therefore the geographical position of the terminal 100.

Such an external device is for example a proximity beacon (“beacon” in English terminology) or a near field communication beacon (“Near Field Communication” in Anglo-Saxon terminology, having the acronym NFC). In the example where the external device is a proximity beacon, the beacon sends to the terminal 100 a Bluetooth signal comprising an identifier of the beacon, this identifier being analyzed by the terminal 100 in order to obtain the geographical position of the beacon and therefore the geographic position of terminal 100.

In the embodiment illustrated in FIG. 4, step S300 for obtaining the geographical area is implemented after step S302 for obtaining the audio and / or visual sequences.

In this embodiment, each sequence can be obtained during the downloading by the terminal 100 of the software application or of the aforementioned web page. The download of the application or of the web page can be triggered by reading a bar code, such as a 2D code or a QR code (acronym of the English terminology "Quick Response"), for example present at the site of the event.

In addition, in this embodiment, step S300 may include, after the sub-step S406 of obtaining the geographical position, a sub-step S408 in which the geographical position of the terminal 100 obtained in the sub-step S406 is compared to the geographic area or areas obtained in step S302. This sub-step S408 makes it possible to determine whether the terminal 100 is positioned in the or one of the geographic zones determined previously.

If the terminal 100 is positioned in a predetermined geographic area, at least one sequence associated with the predetermined geographic area is restored, during a step S304, by the rendering module 106 of the terminal 100.

Alternatively, step S300 of obtaining the geographical area is implemented before step S302 of obtaining at least one sequence. The step S300 for obtaining the geographical area may then comprise, after the sub-step S406 for obtaining the geographical position, a sub-step for determining the geographical area comprising said geographical position. Only the sequence or sequences associated with the geographical area can then be obtained in step S302 for obtaining at least one sequence.

In this variant, the sequence or sequences are for example obtained by consulting a remote server. More specifically, the terminal 100 sends the server a message comprising an identifier of the geographic area obtained. The server storing in memory one or more associations between geographic area and sequence, it is able to find the sequence or sequences associated with the identifier received. The server then sends to the terminal 100 the sequence or sequences associated with the identifier. The server can also send to terminal 100 the sequence or sequences associated with geographic areas close to the geographic area obtained.

The sequence or sequences associated with the geographical area are then restored in step S304, by means of the rendering module 106 of the terminal 100.

The method may include, after step S300 or step S302, a verification step S414, by the verification module 108, of the starting condition or conditions associated with the sequence corresponding to the geographical area in which the position is positioned. terminal 100. The sequence associated with the predetermined geographic area is then restored, in step S304 of restitution, if the terminal 100 is positioned in the predetermined geographic area and if the starting condition or conditions associated with the sequence are verified.

The starting condition thus makes it possible to synchronize the restitution of the sequences, in order to create a coordinated and coherent rendering of the determined scenario. A large number of terminals (for example several thousand) can then play back one or more sequences in a synchronized manner.

When the starting condition is a temporal starting point obtained by means of the clock of the terminal 100, the temporal starting point is determined by taking into account a reference clock. The reference clock is in an example an atomic clock. The synchronization of the terminals with an atomic clock allows synchronization of all the terminals with one another on the order of a tenth of a second.

The determination of the time starting point taking into account a reference clock allows synchronization of all the terminals implementing the restitution method according to the invention. Indeed, all the terminals then take into account the same reference clock. Thus, the sequences can be reproduced in a synchronized manner by the terminals, so that the overall rendering of the restored sequences is precise and consistent.

More precisely, in the case where the clock of the terminal 100 is synchronized with the reference clock, the time starting point is a first determined instant, when this first instant is reached by the reference clock and therefore by the terminal 100 clock.

In addition, in the case where the clock of the terminal 100 is not synchronized with the reference clock, the time difference between the clock of the terminal 100 and the reference clock is first calculated, the point of time departure is then equal to a second instant determined to be equal to the first instant at which the time offset is added (if the clock of terminal 100 is late with respect to the reference clock) or is removed (if the clock of terminal 100 is ahead of the reference clock), when this second instant is reached by the clock of terminal 100.

When the starting condition is a predetermined sound, the verification module 108 captures, by means of the microphone, the surrounding sounds. Next, the verification module 108 analyzes the captured surrounding sounds in order to compare them with the predetermined sound. This analysis is preferably carried out in real time. When one of the surrounding sounds captured corresponds to the predetermined sound, the starting condition is checked.

When the starting condition is a predetermined movement of the terminal 100, the verification module 108 measures its movements, by means of the accelerometer. Next, the verification module 108 analyzes the measured movements in order to compare them with the predetermined movement. This analysis is preferably carried out in real time. When one of the measured movements corresponds to the predetermined movement, the starting condition is checked.

The predetermined movement can for example correspond to the movement carried out by the terminal 100 when a user of the terminal raises his arm holding the terminal 100.

When the starting condition is a predetermined image, the verification module 108 captures surrounding images, by means of the camera. Next, the verification module 108 analyzes the captured images. This analysis is preferably carried out in real time. When one of the captured images corresponds to the predetermined image, the starting condition is checked.

When the starting condition is the reception of a message, the verification module 108 verifies that the message is received. The message is for example sent by an external server.

In the example where several sequences are obtained in the obtaining step S302, the starting condition or conditions associated with each sequence can be checked.

In one example, a plurality of different scenarios are obtained in step S302 of obtaining at least one sequence, each scenario comprising at least one sequence. The method can then also comprise a step S410 of selecting a scenario as a function of a parameter relating to at least one detected position, carried out by a selection module 110. At least one sequence of the selected scenario is then restored to the step S304 of restitution.

The step S410 for selecting a scenario includes a sub-step S412 for obtaining the parameter. Typically, the terminal 100 receives at least one message from another terminal having implemented the sub-step S406 for obtaining geographical position, the message comprising the detected geographical position from this other terminal. The terminal 100 then analyzes the detected geographic position or positions received and the position of the terminal 100 detected in step S406, in order to obtain the parameter.

The parameter relating to at least one detected position is for example a number of detected geographic positions, and / or a density of detected geographic positions. The parameter relating to at least one detected position can also be an accuracy of the geographic positions detected.

Thus, the method can be adapted to the number of terminals implementing it, to the distribution of these terminals, and / or to the accuracy of the geolocation of these terminals. Thus, if the spectators are few, a simple scenario can be selected so that the rendering of the scenario is understandable. In addition, if the place of the event is not filled uniformly, a scenario taking into account this lack of uniformity can be chosen, so that the rendering of the scenario is understandable.

Position accuracy can be used in combination with position density. Indeed, the more the spectators are numerous, the less the precision is important. A wide motif or an ola can then be selected as a scenario.

In one embodiment, a system comprising several terminals, conforming to the terminal 100 of FIG. 1, implements the restitution method as described with reference to FIG. 4.

More precisely, each terminal 100 of the system implements steps S300, S302, S304, S406, S408, S410, S412 and / or S414 of the restitution process. Two terminals positioned in the same geographic area can thus play back the same sequence, and two terminals positioned in different geographic areas can play back two different sequences.

The sequences reproduced by the terminals 100 form a pattern, an animation, and / or an overall piece of music, which can be seen or listened to by the performer, or which can also be recorded by a camera or a microphone.

FIG. 5 shows an example of rendering 500 when the sequences are monochrome images 510, 520.

In this example, a performance hall 530 is divided into two geographic areas, a first area 540 being associated with a first sequence taking the form of a red monochrome image and a second area 550 being associated with a second sequence taking the form of 'a white monochrome image. The scenario thus comprises the first sequence and the second sequence.

The first zone 540 is defined by the numbers of the seats present in the first zone 540, and the second zone 550 is defined by the numbers of the seats present in the second zone 550.

Spectators 560 enter their seat numbers, by means of a man-machine interface of their mobile phone 570, during the sub-step S406 of obtaining the geographical position of their terminals 570. Next, each mobile phone 570 compares the seat number entered with the seat numbers of each geographic area 540, 550. If the seat number entered corresponds to a seat number of the first geographic area 540, the mobile phone 570 displays a red monochrome image 510. Similarly , if the seat number entered corresponds to a seat number in the second geographical area 550, the mobile telephone 570 displays a white monochrome image 520. Each spectator 560 can then raise his mobile telephone 570 so that it can be seen by intervener 580. The global rendering 500 of the restored sequences 510, 520 then in this example forms a red heart (formed by the red monochrome images 51 0 restored) on a white background (formed by the monochrome white images 520 restored).

Other scenarios can be envisaged, these scenarios can take the form of an animation and therefore be more complex.

In one example, the first area 540 of the performance hall 530 of FIG. 5 can be associated with a first sequence taking the form of a red monochrome image for a first predetermined duration (of the order of a second), then of a white monochrome image for a first predetermined duration (of the order of a second), the reproduction of the two images being able to be repeated. The second area 550 can be associated with a second sequence taking the form of a white monochrome image. The overall rendering of the restored sequences then forms a flashing red heart (formed by the restitution of the first sequence by a plurality of terminals) on a white background (formed by the restitution of the second sequence by a plurality of terminals).

Scenario renderings can also take the form of text with displacement, an ola or wave, a logo or a brand, etc.

When the rendering takes the form of a wave, the geographic areas take the form of columns so that the terminals positioned in the same column display a monochrome image at the same time.

In one embodiment, a system comprising several terminals, conforming to the terminal 100 of FIG. 1, and a server, implements the restitution method as described with reference to FIG. 4.

In this embodiment, the server can implement step S302 of obtaining at least one sequence. Each terminal can implement the sub-step S406 of obtaining the geographical position, then send in a message the geographical position obtained to the server.

The server then implements the comparison sub-step S408 for each geographic position received, and sends, to each terminal, the sequence corresponding to the geographic area in which the terminal is positioned, so that the terminal returns it, to the step S306. Furthermore, the server can implement the selection step S410, from the geographic positions received.

Steps S300, S302, S304, S406, S408, S410, S412 and / or S414 can be repeated by the same terminal. This reiteration can typically be triggered by a displacement of the terminal, implying a change of geographical area.
