Description

Description

Title of the invention: Method of reproducing on a terminal a main content by restoring secondary content associated with a displayed object, terminal, server, and corresponding computer program.

1. Field of the invention

The field of the invention is that of the reproduction of visual and / or audiovisual content on a communication terminal equipped with a screen. More specifically, the invention relates to the fact that the main content comprises objects appearing on the screen, that these objects are associated with secondary content, and that the gaze of the spectator, landing for a certain time on this object triggers the restitution of secondary content.

2. Prior art

These means of reproduction are very frequently used in the homes of individuals, in communities but also in the professional mode where videoconferencing means are increasingly used. The ubiquitous means of communication today allow visual content to be seen at any time and in a wide variety of places. The terminals can be portable like smart phones (or “smartphone” in Anglo-Saxon language), tablets, portable computers, or located in a particular place (like a decoder (“Set top box” in Anglo-Saxon language) or desktop computer Very generally the user selects a broadcasting channel and starts the reproduction of the content broadcast in real time on the screen of his terminal.

Broadcast platforms are full of multimedia content, allowing viewers to choose a document that is of interest to him. Navigating through very large lists of available content can be tedious, the manufacturers have developed means of selecting content to present a short list of those that best suit the tastes of viewers. The contents are associated with metadata which characterize them and which are compared with the data of profile of the spectator. When the data is correlated, the associated content is likely to appeal to viewers. Broadcast platforms can receive a spectator profile and in return provide a shortlist of content identifiers that meet the tastes of the spectators.

Even when the content perfectly matches their tastes, the viewer may want additions that are not found in the content they have selected. Take for example a football match, the spectator may want to know in real time the identity of the player who has the ball, details on the action of play which is in progress, the sound picked up at a certain place of the stadium. , or any other information related to the content currently broadcast. This spectator in particular may wish to enrich the content currently reproduced on his screen with other content. He can then launch a request on the communication network to obtain answers to his questions, for example the age of a player, or the identity of a referee. During this interrogation, he turns away from his screen to interact with another means of communication and may lose track of the event.

There is therefore a real need for a process for reproducing content displayed on a screen which allows a viewer to obtain additions relating to an interest for him.

There is therefore a need for a new way of interacting with its receiver to trigger the reproduction of audio and / or video content which is associated with an object generating interest for a viewer.

3. Statement of the invention

An object of the present invention is to provide a solution for enriching visual or audiovisual content by adding to the display of said content additional textual, audio and / or video elements associated with an object displayed in said content.

Another object of the present invention is to provide a solution allowing spectators to easily order the enrichment of visual or audiovisual content by rendering at least one additional text, audio and / or video element associated with an object. displayed in said content.

According to a first aspect, there is proposed a method of reproduction, on a terminal, of enriched multimedia content comprising the following steps:

- reception of a multimedia stream and display on a screen of the terminal of visual content called "main extract of this multimedia stream,

- determination using a camera of an area of the screen called "area of interest" on which the gaze of the viewer is focused,

- identification in the area of interest, of at least one visual object of the visual content displayed,

- obtaining audio and / or visual content called "secondary" associated with the identified visual object,

- playback of secondary audio and / or video content on the terminal screen, at the same time as the reproduction of at least part of the main content.

Such a method according to this embodiment makes it possible to enrich a main content by restoring secondary content associated with an object which appears in said content and which is selected by a simple glance from the viewer. In this way, the spectator does not need to interact with the hands or with the voice on a user interface, a simple glance applied more or less long on an object presented visually in the main content is enough to start the restitution of this secondary content.

According to a particular embodiment, the step of detecting an object occurs when the coordinates of the area of interest correspond to the coordinates of an object for a determined duration of reproduction of at least part of the content main. In this way, a look at the object of too short a duration does not trigger and inadvertently, the enrichment of the displayed content.

According to a particular embodiment, the secondary content is a text displayed near the object on the screen, said text being extracted from the secondary content. In this way, the spectator can read additional data concerning the object pointed by his gaze.

According to a particular embodiment, the secondary content is video content which is displayed in a medallion within the image of the main content. In this way, the viewer can see additional details relating to the object pointed by his gaze.

According to a particular embodiment, the reproduction of the secondary content is interrupted after a determined period. In this way, the enrichment automatically disappears after a specified period.

According to a particular embodiment, the reproduction of the secondary content is interrupted when the detected object no longer appears in the main stream. In this way, the enrichment of the main content continues until the object ceases to appear in the images of the main stream.

According to a particular embodiment, the reproduction of the secondary content is interrupted when the sequence shot of the video of the main stream stops to transmit a new sequence shot. In this way, the enrichment only lasts for the time of a sequence shot.

According to a particular embodiment, the reproduction method comprises steps prior to the dissemination of the main stream consisting in identifying a determined number of objects, in identifying secondary content having a link with said identified objects and in associating these secondary content with these objects. In this way, the identification of objects and the association can be carried out in advance and be reusable for other content.

According to a particular embodiment, the steps for selecting secondary multimedia content are carried out at the level of the reproduction system. In this way, the enrichment of the main content is personalized at each terminal performing the reproduction of this content.

According to a particular embodiment, the secondary content is a video stream whose images have a resolution higher than the images of the main stream, the content of the area of interest being displayed with a resolution higher than that of the objects located around of this area of interest. In this way, the area of the screen under the spectator's gaze is displayed with better definition.

According to a particular embodiment, the secondary content is an audio stream associated with the object displayed in the area of interest. In this way, the viewer receives auditory signals providing a complement to the main content signals.

In another aspect, there is proposed a terminal for reproducing enriched multimedia content comprising means for receiving visual or audiovisual content, a means of reproduction allowing at least the display of visual content or so-called "mainstream" audiovisual, a means of detecting the direction of the gaze of a spectator towards the displayed images of the main content and of calculating the coordinates of an area called "area of interest" on which the gaze of the spectator is focused . The reception means also receives at least one audio and / or visual content called "secondary" associated with an object appearing in the images of the main content at a determined time, the terminal further comprising means for detecting the presence of a object displayed in the area of interest during this determined moment triggering the selection of the secondary content associated with this object and the reproduction on the means of reproduction of the enriched multimedia content as long as the viewer's gaze remains focused on the area of interest which contains this object, the enriched content being composed of at least part of the main content and the selected secondary content.

Such a terminal is particularly suitable for implementing the method of reproducing content as described above. This terminal may of course include the various characteristics relating to the process for reproducing content as proposed above, which can be combined or taken in isolation. Thus, the characteristics and advantages of this terminal are the same as those of the reproduction process.

According to another aspect, there is proposed a server for producing enriched multimedia content comprising a means of communication to a remote reproduction terminal and a means of storing documents composed of visual or audiovisual content called "main ", And at least one audio and / or visual content called" secondary "associated with an object appearing in images of the main content at a given time. The storage means comprises means associating at least one secondary content with positions in the image of an object appearing in the main content at a determined time, the reception coming from the reproduction terminal of coordinates of a zone of image and of a fixed duration triggering a means of detecting the presence of an object in this area of the main content during the fixed-term period, the communication means transmitting to the remote reproduction terminal at least one associated secondary content to the object which is detected in the image area appearing in the main stream during this determined period.

Such a server is particularly suitable for implementing the method of reproducing content as described above. This server may include the various characteristics relating to the process for reproducing content as proposed above, which can be combined or taken in isolation. Thus, the characteristics and advantages of this terminal are the same as those of the reproduction process.

In another aspect, there is provided a computer program product comprising program code instructions for the execution of the steps of the method for reproducing enriched multimedia content as described below when said program is executed on a central unit.

In another aspect, there is provided a non-transient recording medium readable by a computer on which is recorded a program comprising instructions for the implementation of a method.

5. Description of an embodiment

The proposed solution makes it possible to enrich a main content by restoring secondary content associated with an object displayed in said content and to launch the restitution of these secondary content by a simple look applied more or less long on the object displayed during reproduction of the main content.

5.1 Devices for implementing the method

Figure 1 shows an audiovisual receiver 1 connected to a display device 2 such as a display screen. The receiver 1 is for example a digital television decoder, an audiovisual terminal provided with means of communication through a digital network, for example an intelligent portable telephone (or "smartphone" in English), a digital tablet, a portable computer. , ... or any other digital device with means of reception and reproduction of visual or audiovisual content. The receiver 1 comprises a central unit 3 connected in particular to a memory 4 containing executable programs, an interface for receiving infrared signals 9 for receiving signals from a remote control 10, a video interface 12 for creating visual signals sent to the television screen 2. The receiver 1 can be integrated into the display screen, for example a large LCD screen comprising a digital television reception module. A variant consists in physically separating the receiver 1 and the screen 2, the receiver 1 then being a decoder connected to a screen or a television 2. According to a preferred embodiment, the receiver is equipped with an interface 5 for communication with a remote server via a digital network 6. Depending on the type of receiver used, communication takes place at short or long range, for example with a wireless local area network (Wifi or Bluetooth). The receiver 1 can also receive audio and / or video data of content transmitted "in streaming". The remote control 10 transmits signals to an interface 9 to control the operation of the receiver 1. The receiver can also include reception means 7 for receiving, using an antenna, visual or audiovisual content transmitted by a broadcasting server via a broadcasting network. The broadcasting server sends encoded and compressed data files over the network for the reproduction of audio and / or visual content, this content also being called “multimedia”. The data files are transmitted in one way or another to receivers 1 to be decoded and decompressed there.

The receiver can also include a storage unit 11 for storing visual or audiovisual content downloaded or broadcast. The storage medium used is for example: a random access memory, a hard disk or an optical disk, it may or may not be removable. The video interface 12 which makes it possible to emit visual signals on the screen 2, is provided with a text generation and graphics circuit making it possible to display on the screen text, graphics, pictograms superimposed or not of visual content. The video interface 12 is controlled by the Central Unit 3 in association with an executable program recorded in the memory 4. The receiver 1 can also include an audio interface 13 for transmitting audio signals to loudspeakers 14 integrated or not, to receiver 1.

The receiver also includes an interface circuit 16 with an image sensor

15, typically a camera oriented towards the spectators in front of the display device 2. The sensor is arranged so as to detect the spectator or spectators who is (are) placed (s) in front of the screen on which the visual content or audiovisual is displayed. According to an alternative embodiment, this camera can be integrated into the receiver 1, generally above the screen, as is the case for certain portable computers, or be fixed at the end of a cable and placed on a support. .

The central unit 3 executes several executable program modules recorded in the memory 4, these modules manage at least the communication and the camera and the display of the enriched content.

A first module analyzes the images acquired by the image sensor. This first module searches for the presence of at least one face in the image. The detection of faces in the image is a technique now known. Once a face is detected, a second module determines the direction of gaze of that person. Techniques known per se allow such determination. Among these techniques, we can cite those based on the infrared lighting of the person's eyes and the analysis of the reflection of this light on the eyeball, the techniques based on the measurement of the surface temperature of the skin, the techniques based on marks worn on the person's face and finally techniques based on the analysis of the image of the faces to estimate the pose and the direction of the gaze. According to certain techniques which use infrared detection, the environment must be lit in this wave range so that the sensor, for example an infrared camera, can detect the presence of a face with sufficient contrast to then carry out a treatment on the 'picture.

A third module makes it possible to determine, depending on the direction of gaze, the point of the image on screen 2 where the gaze of the person is posed. Knowing the 3D position of the face, the direction of the gaze and the position of the screen (and its shape) a simple calculation of the intersection gives the location of the projected image which is viewed. The point of the image where the gaze is posed is identified by a pixel referenced by its abscissa and its ordinate. The area around this point is therefore under the direct gaze of the person. Knowing the position in the face space, the direction of the gaze and the position as well as the dimensions of the screen, this module determines where on the screen the gaze of the person is posed.

According to an exemplary embodiment, the coordinates of the place on the screen where the gaze of the person is placed, are transmitted to a remote server which provides elements intended to enrich the audio and / or visual content. According to a variant, the enrichment can be carried out locally, at the level of the receiver which will then be endowed with sufficient computing power.

Fig.2 is a diagram showing different elements of a remote server capable of implementing the invention according to an exemplary embodiment. The audio and / or video enrichment data are calculated and produced by a remote server 20. Said server 20 comprises a central unit 21, a memory 22 containing at least one executable program, a memory containing a recorded database 23 in a storage area preferably produced by a hard disk and a communication interface 24 for establishing bidirectional communications via the bidirectional network 6 with at least one receiver 1 as described above. The server 20 can also receive information from the broadcasting network through an interface 25. The information recorded in the database 23 concerns the audio and / or visual content.

After having detailed in the form of an example the various devices implementing the invention, we will now explain how they cooperate.

5.2 The steps of the method according to a simple embodiment

The flowchart of FIG. 3 presents the main steps of the method for reproducing enriched multimedia content on a receiver 1, according to an exemplary embodiment. These steps are preferably implemented by a computer program stored in the storage devices 4 and 22 and executed by the processors 3 and 21 at the level of the receiver 2 and / or of the server 20.

First, a user turns on his audiovisual receiver 1, navigates through an electronic program guide and selects visual or audiovisual content broadcast for the purpose of reproduction on the screen (step 3.1), this content is qualified as " main ". In step 3.2, the user starts playing the main content on the screen. Concomitantly with the display, the central unit 3 executes the module which analyzes the image acquired by the camera to determine the location of the displayed image on which the user's gaze is focused (step 3.3). The signal display and analysis modules of the camera can be executed in parallel on the same central unit 3, which does not exclude that these two functions are carried out by specialized circuits. In all cases, the camera's signal analysis module transmits to the display module the coordinates of the point of the image, known as the “gaze point” which is exactly in the direction of the user's gaze (step 3.4 ). These coordinates are expressed in a coordinate system linked to the image. The transmission of the coordinates of this point can be carried out at the request of the display module, for example during the production of each new image, or at regular time intervals, every 200 milliseconds for example.

In step 3.5, the image analysis module determines whether the user's gaze is fixed on the same object. This step consists of analyzing the visual content of the main content and defining a certain number of objects present at specific locations in this visual content. Following this analysis, a certain number of detected objects are associated with coordinates where they appear on the screen 2. If the coordinates of the point of view of the user correspond for a certain time, a second for example, to the coordinates of an object present on the screen then this object is marked as being of interest to the user. The reproduction process will then enrich the content being reproduced by rendering secondary audio and / or video content, this content being associated with the object located in the point of view determined in step 3.4.

In step 3.6, an audio, visual or audiovisual element is sought according to the criterion that it is related to the object selected in the main content. The search can be carried out in metadata associated with the main content, or by a request on the Internet using identifiers associated with the object pointed by the viewer's gaze, or in a database which is associated with the main content and which includes data associations such as:

[0049] - identifier of an object present in the main content,

- coordinates in the image where the object is present and moments of appearance of this object,

- secondary content (s) (text, audio, visual, audiovisual, ...) associated with the objects.

Once secondary content associated with the object pointed by the spectator's gaze is detected, this content is immediately restored either on screen 2, or by the speakers 14, or by the two reproduction means.

The program then loops back to step 3.3 to continue analyzing the viewer's gaze and possibly stop the enrichment if the viewer stops looking at an object. The loop constituted by steps 3.3 to 3.7 takes place at regular intervals with a duration T of 200 milliseconds for example.

If the analysis of the images captured by the camera reveals:

- no one is detected in front of the screen, or

- that the spectator (s) no longer look at the screen, or

- that the spectator (s) look (s) at the screen without fixing a particular object, or

- that an enrichment stop command is entered on the remote control, then the receiver switches to normal mode, and stops the restitution of the secondary content associated with the object pointed at by the gaze.

According to an improvement, the secondary content is associated with information defining a time window for its restitution on the receiver 1. The limits of this time window can be defined by the presence of the associated object in the images of the main content. . Let us take for example a television news in which reports are presented, certain objects appearing during this report are characteristic of this one and a spectator can want to receive a supplement of this report. He then looks at one of these objects and secondary content planned to complete this report is restored. This content is rendered even if this object is not put on the screen. The playback of secondary content stops when the report ceases to be reproduced and the receiver switches to normal mode, without enriching the main content.

[0057] FIG. 4.a, 4.b, 4.c and 4.d represent four examples of screen appearances showing content displayed with and without enrichment, these screen appearances are produced on the screen of a tablet. These examples relate to a football match broadcast on a digital television channel and reproduced on a large number of receivers. This match is filmed by several cameras, some of which are configured to follow certain players. Fig. 4.b shows two players on the screen, one of whom (the one on the left) is watched for a period of time determined by a spectator. The enrichment mode is then applied for this receiver, the latter transmits visual signals which only show the player on the left in a larger plan, that is to say by zooming in on him. Advantageously, the name of this player appears by a text displayed near this player, possibly adding other data: his club, his age, ... At another time of the reproduction of this main content, Fig . 4.c shows on screen these two players, one of whom on the right is watched for a period determined by another spectator on another receiver. The enrichment mode is then applied for this other receiver, and the image of FIG. 4.d appears on the screen, showing only the player on the right by zooming in on him. We can thus see that, although having selected the same main content, the two receivers have very different screen appearances, these appearances being a function of the interest of each spectator watching their screens.

5.3 Specific examples of implementation of the process

According to a particular embodiment, the secondary content is a part of the image with a higher resolution. In this way, the object which is pointed by the spectator’s gaze is seen with better resolution. It is known that digital image data is encoded and compressed before being transported. During reproduction, this data is decoded and decompressed before sending it to a graphics processor responsible for displaying the image on a screen or any other means of projection. This data has multiple levels of image resolution to achieve an image before maximum resolution.

According to this particular embodiment, the image data is decoded and decompressed to an intermediate level, thus requiring an average computing power for a standard receiver. In the enrichment mode, a screen area is defined around the point of view and the image signals displaying this area are decoded and decompressed with a maximum resolution. A composite image is thus produced comprising an improved definition area within a weaker definition image. In this way, the viewer looks at a portion of the image with better definition and the rest of the screen, which is not viewed, is displayed at a lower resolution. This embodiment has the advantage of saving overall computing power dedicated to decompressing and decoding video data.

According to a particular embodiment, the producer or the broadcaster of the main content analyzes the visual content himself to determine the objects likely to interest the spectators. The producer or distributor of the content then produces the elements already presented previously, namely:

[0062] - identifier of an object present in the main content,

[0063] coordinates in the image where the object is present and moments of appearance of this object,

- secondary content (s) (text, audio, visual, audiovisual, etc.) associated with the objects.

The producer or broadcaster of the main content broadcasts these elements with the main content so that each receiver 1 processes them and can switch to an enrichment mode, suitable for satisfying the spectator (s).

When the receiver knows in advance the objects present in the main content and the position of these objects, it can add a graphic characteristic to their representations appearing on the screen 2. For example, by knowing the coordinates of the object present on the screen, the receiver reinforces its outline by adding a color to it. In this way, the viewer perceives that there is secondary content associated with this object and can launch its rendering with a simple look.

According to a particular embodiment, the main content presents a classical music concert, a so-called main audio stream broadcasts what is heard in the room. Audio channels are picked up by specific microphones placed near certain musicians and constitute as much secondary content associated with these musicians. When a spectator fixes for a certain time the image displayed on the screen of a certain musician, the receiver detects the point of view and deduces which musician it is, positions himself in enrichment mode and mixes the content primary audio with secondary audio content associated with that musician in front of the viewer. The levels of the audio signals produced by the mix are for example 50% the main content and 50% the secondary content, in this way each spectator of this concert more easily perceives the musical signals produced by such or such musician.

According to a particular embodiment, the secondary content includes a video component associated with an object appearing on the screen. The main content is displayed on the screen and, when a spectator points his gaze for a certain time on a displayed object, then the video component of the secondary content associated with this object is displayed in a medallion within the image of the main content.

The method of reproduction on a terminal of enriched multimedia content can be implemented in software form, as described above, in which case it takes the form of a program executable by a processor, or in hardware form (or "hardware"), such as an application-specific integrated circuit (ASIC), a system on a chip (SOC), or in the form of a combination of hardware and software elements, such as for example a software program intended to be loaded and executed on an FPGA type component. When the terminal and / or the server providing the secondary content are switched on, the code instructions of the computer program are for example loaded into a RAM memory before being executed by the processor of the central unit. The processor of the central processing unit is configured to implement the method of reproducing enriched main content.

Although described through a number of detailed exemplary embodiments, the methods proposed and the corresponding devices include different variants, modifications and improvements which will be obvious to those skilled in the art, it being understood that these various variants, modifications and improvements form part of the scope of the invention, as defined by the claims which follow. In addition, different aspects and characteristics described above can be implemented together, or separately, or else substituted for one another, and all of the different combinations and sub-combinations of the aspects and characteristics are part of the scope of the 'invention. In addition, some devices described above may not incorporate all of the modules and functions described for the embodiments.
