    Equipment and method for controlling the representation of multimedia content on a touch screen of the equipment
    Invention background
    The invention relates to the general field of software programs for representing multimedia content on a screen. It relates more particularly to the control by a time bar of the representation of the multimedia content.
    The software programs, currently available on the market, allowing the representation of multimedia content on a screen, have linear time bars. Among these software programs, we cite as examples, Dailymotion and YouTube (registered trademarks).
    The time bars are known by the English name "time-line".
    When a user wishes to go back up to a specific time on a time bar to display the multimedia content from this time, he is obliged to perform a linear movement throughout the linear time bar.
    Depending on the size of the screen, such a movement can cause movement at the user's wrist, or even at the elbow.
    On a screen of mobile equipment that can be held by the hand, such as a smartphone or an electronic tablet, to select a specific moment on the linear time bar, the user may be forced to perform with his thumb or index finger, a disturbing and uncomfortable linear movement, or to use his second hand to make the selection.
    From a human physiology point of view, these movements are undesirable and they affect the quality of the user's experience.
    There is a solution, used in particular for the playback of multimedia content in direct play / broadcast mode, which consists in displaying only a reduced time window on the linear time bar, for example a time bar with a cursor in the middle with a possibility of retreating and advancing in time. Having a reduced window makes it possible to reduce the distance of the linear movements carried out by the user, however this solution obliges the user to contort his hand to reach the center of this time bar, even to use both hands.
    There is therefore a need for controlling the representation of multimedia content which does not have the drawbacks of the state of the art.
    Subject and summary of the invention
    The invention relates to a method for controlling the representation of multimedia content on a touch screen of an item of equipment, the representation being controlled by a time bar, the method comprising steps of:
    BE2019 / 5700 - display of the time bar, the time bar comprising a cursor and a rounded curve turned towards the edge of the screen closest to this curve, said curve representing a time window of a determined duration of the multimedia content;
    - detection of a movement of a user's contact on the touch screen along the time bar;
    - adjustment of the start and end of the time window at least as a function of the detected movement; and - restitution of the multimedia content on said touch screen and / or another screen from an instant determined by the time window and by positioning the cursor.
    Correlatively, the invention relates to equipment comprising a touch screen and making it possible to control the representation of multimedia content on its screen, the representation being controlled by a time bar, the equipment comprising:
    Means configured to display the time bar, the time bar comprising a cursor and a rounded curve facing the edge of the screen closest to this curve, said curve representing a time window of a determined duration of the multimedia content;
    - means configured to detect a movement of a contact of a user on the touch screen along the time bar;
    - means configured to adjust the start and end of the time window at least as a function of the detected movement; and - means configured to restore the multimedia content on said touch screen and / or another screen from an instant determined by the time window and by positioning the cursor.
    The characteristics and advantages of the method for controlling the representation of multimedia content on a screen according to the invention presented below apply in the same way to equipment according to the invention, and vice versa.
    Within the meaning of the invention, the term “rounded curve” must be interpreted as any curve comprising at least one non-rectilinear segment.
    Thanks to the rounded shape of the curve, the invention allows a user who wishes to select a determined instant from which the multimedia content will be rendered, to perform a rotation movement with his thumb on the touch screen. This movement is in line with the physiology of a human hand. The invention thus improves the user experience.
    Since the adjustment of the start and end of the time window is a function of the user's tactile movement, the invention allows the user to choose the window represented by the time bar.
    In addition, by the movement of the user along the time bar, the user can have an overview of all the multimedia content, without being limited to the part of the content.
    BE2019 / 5700 corresponding to the time window initially included in the time bar, this window being adjustable.
    Within the meaning of the invention, "rounded" must be understood in a non-restrictive manner and is not limited to a circular curve. It aims in particular to cover any curve comprising a portion of a circle, a portion of an ellipse, a portion of an oval, a parabolic curve, or other shape adapted from an ergometric point of view to represent the window of time while ensuring a natural and simple movement of the user contact on the screen when it is operated with a finger of a hand holding the equipment to control the time bar.
    Within the meaning of the invention, the rounded curve forms a "U" whose branches, preferably non-rectilinear, are directed towards said screen edge closest to this curve.
    Within the meaning of the invention, observed from the edge of the screen closest to the rounded curve, this curve is a concave curve.
    In particular, when the rounded curve has two points of intersection with the edge of the screen closest to it, the curve forms with the segment of this edge between the two points of intersection, a convex assembly. We recall that a set is said to be convex if it contains any segment passing through two of its points. If we take any two points A and B of the set formed by the rounded curve and the segment of the edge bounded by the points of intersection, the segment which joins the two points A and B is entirely contained in the together.
    For example, the time bar can include a semicircle located on one of the four sides of a rectangular screen, or a quarter circle located in one of the four corners of the screen.
    In one embodiment, the time bar comprises a complete circle, a part of which is close to an edge of the screen, is hidden, for example by a display filter. The visible part of this circle constitutes a rounded curve in accordance with the invention.
    Equipment according to the invention can be a computer, a telephone of the smartphone type, an electronic tablet, a television, a connected watch (of the Smart Watch for example), a multimedia content acquisition device such as a camera. or a camera comprising a touch screen, a digital console, a multi-touch control or information desk, a touch remote control, a touch numeric keypad, a wall or an interactive transparent or opaque tactile table, a window or a window interactive touch screen, video projection equipment with motion sensor, or any other equipment comprising a touch screen and capable of rendering multimedia content on this screen.
    Preferably, equipment according to the invention renders the multimedia content on its own touch screen.
    In another embodiment, equipment according to the invention renders the multimedia content on a screen of another device. For example, equipment conforming to
    BE2019 / 5700 the invention, of the mobile telephone type, can be used as a touch-sensitive remote control for rendering multimedia content on a television screen.
    In one embodiment of the invention, the equipment renders multimedia content on several screens.
    Within the meaning of the invention, the multimedia content can be a video, or a sound, or a photo slideshow, or a slideshow of multimedia slides.
    Within the meaning of the invention, the start and the end of the time window vary according to the contact of the user on the screen along the time bar.
    In one embodiment, the start and the end of the time window vary as a function of the duration of the multimedia content obtained.
    In one embodiment, the start and the end of the time window vary as the multimedia content is restored.
    In one embodiment, upon detection of movement on the screen, the multimedia content is reproduced, directly, from the instant of the multimedia content pointed by the cursor.
    In another mode, the multimedia content is only reproduced when the user has validated the restitution from the instant pointed by the cursor, for example by pressing the cursor or a play button.
    In one embodiment, the multimedia content includes significant events, for example a video of a football match comprising goals, assists, faults, player replacements or other significant events in the game. he invention further comprises a step of obtaining data representative of these significant events, for example the instant of an event, the nature of the event, the name of the player or players concerned by the event, the name of the team concerned by the event, statistics resulting from the event, etc.
    In this embodiment, the display step includes a representation of markers on the time bar to indicate instants corresponding to the significant events.
    The position of the markers is determined according to the instants which they represent and the start and the end of the time window. The position of the markers can be determined manually, or determined automatically from the data representative of the marking events.
    The invention thus allows the user to know intuitively the instants corresponding to the significant events, he can therefore select, according to the markers, the time window displayed on the time bar, and also the instant of multimedia content playback.
    According to the invention, a marker is a graphic indicator. It can be representative of the significant event to which it corresponds.
    BE2019 / 5700
    In one embodiment, the start and end of the time window are automatically adjusted according to the data representative of these significant events.
    The invention therefore makes it possible to improve the user experience by ensuring a reasonable number of markers on the time bar, on the one hand to highlight the significant events, on the other hand so that the bar is not cluttered by the markers and so that the markers are sufficiently separated so that the user can distinguish between them.
    In fact, adjusting the time window as a function of the data representative of the significant events ensures clear visibility of the markers on the time bar.
    In one embodiment, the markers are selectable buttons. When the user presses a marker, the multimedia content is restored from the moment of the significant event represented by this marker.
    In one embodiment, a said marker comprises an image representative of the nature of the marking event to which it corresponds, for example an image of a ball to represent a goal.
    In one embodiment, when the user presses a marker or when the user moves the marker in front of the cursor, its graphic representation changes, for example by an enlargement of its size or a change of its color. This embodiment makes it possible to bring out the marker selected by the user and capable of defining the instant of restitution of the multimedia content.
    In one embodiment, when a marker passes in front of the cursor when the multimedia content is read, its graphic representation changes to highlight the event to which it corresponds and to attract the attention of the user.
    In one embodiment, a marker generates an audible signal when selected by the user or when pointed to by the cursor. The sound signal may be representative of the event represented by the marker, for example an applause to represent a decisive pass.
    In one embodiment, a marker generates a graphic animation when it is selected by the user or when it is pointed at by the cursor. This graphic animation can be representative of the event represented by the marker.
    In one embodiment, two successive markers are preferably spaced apart by at least one size of a finger so that the user can easily select one of the two markers.
    The article "Touch Target Sizes" by "Luke Wroblewski" published on May 04, 2010 is a summary of the dimensions and spacings suggested by companies offering software intended to be used on a touch screen. According to this article, the company Ubuntu (registered trademark) considers that the touch of a finger (pad of the finger) has a diameter of 10 to 14 mm. The
    BE2019 / 5700 Nokia company (registered trademark) considers that this diameter is not less than 1 cm. We note that the article 3-D Finite-Element Models of Human and Monkey Fingertips to Investigate the Mechanics of Tactile Sense by Dandekar et al., Published in the Journal of Biomechanical Engineering, Oct. 2003, Vol. 125 reports that the size (diameter) of the touch of a human finger (pad of the finger) is of the order of 10 to 14 mm and that the tip of a human finger (fingertrip) has a diameter of 8 to 10 mm.
    In one embodiment, the user can add, move, filter or delete markers. The representation of multimedia content is thus personalized according to user preferences.
    In one embodiment, the user can classify markers in a list of favorites, in order to review them later, to comment on them, or to share them on social networks or with his contacts.
    In one embodiment, the significant events are of at least two different natures. In this mode, the time bar comprises at least two said rounded curves facing the edge of the screen closest to said curves, the curves being parallel. Each of the rounded curves relates to a type of significant event. Markers indicating instants corresponding to significant events of a given nature are represented on the curve relating to this nature of events.
    In the example of implementation of the method of [Invention for controlling the representation of a video of a football match, the significant events relate to two football teams, the time bar comprises two parallel curves and each of these curves include markers relating to one of the two football teams.
    This embodiment makes it possible to separate the markers relating to events of different natures. The user can then have a clear vision of each type of significant event, for example the events relating to each team during a football match.
    In the example of representation of a video of a football match, the time bar allows the user to have a visual summary of the match thanks to the placement of the markers in the two curves corresponding to the two teams.
    In another example of implementation of the invention, the multimedia content is a video of a competition between a number "n" of players and at "m" different stages, such as a tennis competition in 5 sets with 4 players. The time bar may contain markers representing the postage of a stage by a player. The time bar can contain “n” parallel curves allowing to have an overview on the progress of each player, or contain “m” parallel curves to have a global vision on the progress of each stage.
    The embodiment where the time bar has a single rounded curve can be implemented to restore multimedia content corresponding to a single nature, for example
    BE2019 / 5700 example a video relating to an individual sport such as golf, acrobatic diving or long jump.
    In one embodiment, the screen has a tolerance zone which, in turn, includes the time bar. The detection step comprises detection of a tactile movement of the user on the screen in the tolerance zone.
    According to this mode, the movement of the user along the time bar does not necessarily follow the same shape of the rounded curve or curves. For example, it is enough to touch the time bar from one of its corners and perform a rectilinear slide so that the bar rotates and the displayed time window is adjusted. This mode allows the user to control the time bar with simple and quick movements.
    In addition, the movement can be detected near the curve and not necessarily on the curve itself, which makes it possible to alleviate the requirements in terms of precision of the movements of the user and therefore to improve his experience.
    In one embodiment, at least one parameter of the time bar, such as its position, its shape, and / or its size are determined according to the nature of the equipment.
    For example, for a tablet, the time bar can be located at the bottom of the screen or on the bottom right corner because it is common to hold a tablet from below with both hands.
    In another example, for a screen of a smartphone held horizontally, the time bar can be located to the right of the screen in a manner easily accessible by the right hand holding the smartphone.
    In one embodiment, the position of the time bar, its shape, and / or its size are determined according to one or more operating systems installed on the equipment and making it possible to execute a software program putting implementing the method of the invention.
    In one embodiment, the position of the time bar, its shape, and / or its size are determined according to an orientation of the screen. For example, the time bar can be positioned at the bottom of the screen when it is oriented vertically, or to the right of the screen when it is oriented horizontally.
    In one embodiment, the software program executing the method of the invention is synchronized with an equipment accelerometer to detect whether the screen thereof is in portrait or landscape format and thus display the corresponding user interface and determine the parameters of the time bar according to the orientation of the screen.
    In one embodiment, the position of the time bar, its shape, and / or its size are determined as a function of the size of the screen. For example, the degree of rounding may be less important for a screen of small dimensions.
    BE2019 / 5700
    Thus, the parameters of the time bar are adapted to the screen on which it is represented in order to ensure an acceptable ergometric rendering and to improve the quality of the user.
    In one embodiment, the method includes a step of determining whether the user uses the screen with his right hand or with his left hand. The position of the time bar is determined according to the hand used by the user on the screen.
    This mode improves the experience for both a left-handed and right-handed person. In addition, the same screen can be used to render multimedia content, easily by one of the two hands of a user, or by different users: the position of the time bar on the screen being modifiable in a way automatic. The determination of the handrail used on the touch screen can be based on one of the methods of the prior art.
    In one embodiment, the position of the time bar is determined according to a language used in the multimedia content, for example on the right of the screen for languages which are written from left to right like the Latin languages, to the left of the screen for languages that are written from right to left like Semitic languages, and at the bottom of the screen for languages that are written from top to bottom like traditional Chinese. This mode aims at ensuring that the time bar does not cover possible writes in multimedia content, such as a title of a video.
    In one embodiment, at least one parameter of the time bar, such as its position, shape, size or color, can be modified by the user, upon detection by the equipment of a said contact movement of the user on his screen.
    This mode makes it possible to satisfy the preferences of each user and to ensure better comfort when rendering multimedia content.
    In one embodiment, the time bar includes a part indicative that the multimedia content is being obtained. The indicative part can be a hatched part or a part with a color or a brightness lower than the rest of the time bar or a part containing a graphic element.
    This mode allows the user to intuitively distinguish multimedia content reproduced in replay mode from replayed content in live broadcast mode.
    This mode also allows the user to intuitively distinguish a multimedia content restored after downloading from a content restored during downloading (in streaming mode in English).
    In one embodiment, the method of the invention comprises a step of representing the time window in segments.
    This mode allows the user, when restoring multimedia content, to better situate himself in the time window.
    BE2019 / 5700
    The segmentation can be identical for all multimedia content. The segmentation can also be determined as a function of the duration of the time window, or as a function of a previously known duration of the multimedia content, or as a function of the nature of the multimedia content.
    For example, to play a video of a football match, the time window can correspond to a number x minutes and be represented in segments, each of a number y <X of minutes. To play a video of a swimming competition, the window can have a duration of z minutes and be represented in segments of w minutes each.
    In one embodiment, the step of representing said time window in segments is a function of the data representative of the significant events. In particular, the segmentation can be determined according to the positions of markers or according to the nature of the marking events.
    In one embodiment, the step of representing into segments takes into account a constraint on the minimum spacing between two neighboring markers to avoid an overlap between these two markers.
    In one embodiment, the step of representing said time window in segments is a function of a duration of a part obtained from the multimedia content. For example, when multimedia content is broadcast live, the segmentation can be adjusted as the multimedia content is obtained.
    In one embodiment, the step of representation into segments and the step of adjustment can be modifiable by the user. The start, end and segmentation order of the time window can therefore be controlled by the user.
    The invention also relates to a computer program on a recording medium, this program being capable of being implemented in a computer or in equipment according to the invention, such as a smartphone, a tablet, a television. or other equipment comprising a touch screen and capable of rendering multimedia content on this screen. This program comprising instructions adapted to the implementation of a method for controlling the representation of multimedia content on a screen, as described above.
    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 computer program can be a software application that can run on a smartphone or tablet.
    The invention also relates to information or recording media readable by a computer, and comprising instructions of the computer program as mentioned above.
    The information or recording media can be any entity or device capable of storing the programs. For example, the supports may include a
    BE2019 / 5700 storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM, or else a magnetic recording means, for example a floppy disc or a hard disk, or a memory flash.
    These media can be hosted on different machines, for example in a cloud network (cloud).
    On the other hand, the information or recording media can be transmissible media such as an electrical or optical signal, which can be routed via an electrical or optical cable, by radio link, by wireless optical link or by other ways.
    The program according to the invention can in particular be downloaded from a network of the Internet type.
    Alternatively, each information or recording 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 method according to the invention.

    Detailed description of the invention
    Figures IA and IB show a graphical interface of a software program according to the invention, according to a first embodiment. In this mode, this Prog software program is installed and executed by Eq equipment according to the invention comprising a touch screen S.
    FIG. 2 is a flowchart representing steps of a method for controlling the representation of multimedia content, in accordance with this first embodiment of the invention.
    The process is implemented by the equipment Eq. A user of the equipment Eq wants to watch multimedia content, for example a video Vd, on the screen S of the equipment Eq, for this he launches the execution of the program Prog. In this example, the user selects the video Vd from a list.
    The equipment Eq can be a smartphone, a tablet, a computer, a television, or other equipment comprising a touch screen S and capable of rendering multimedia content Vd on this screen S.
    During a step E100, the equipment Eq displays a time bar TL on the right of the screen S.
    In this example, the position, size and shape of the time bar are defined by default. The TL time bar is placed in the middle of the right side of the S screen. The size of the TL time bar is adapted to an average size of one hand and to the size of the S screen.
    This time bar TL comprises a cursor CRS and a semicircle which represents a time window FT of a determined duration of the video Vd.
    In this embodiment, the CRS cursor is placed in the center of the time bar. Alternatively, the position of the CRS cursor may be different from the center.
    In this embodiment, the CRS cursor is visible.
    In this example, the Vd video lasts 2 hours. The restitution of this Vd is in replay or catch-up mode.
    During a step E300, and following the selection of the video Vd by the user, the equipment Eq determines the start and the end of the time window FT. The start is determined at time 0 of the video Vd and the end of the FT window is determined at 30 minutes as shown in FIG. IA. This determination is made as a function of the duration of the video Vd and as a function of parameters ensuring a good visual rendering of the representation of the time bar.
    During a step E400, the equipment Eq divides the time window FT into segments each corresponding to 5 minutes, the duration of each segment being calculated by the program Prog as a function of the duration of the window FT and the duration of the video Vd. Dashes are represented on the time bar TL to represent the instants 5, 10, 15, 20, 25 and 30 minutes, which correspond to the ends of the segments.
    BE2019 / 5700
    In another mode, during the selection of the video Vd, the equipment Eq obtains the duration of the time window FT and the segmentation order by reading from a server for example.
    During a step E500, the equipment Eq obtains the video Vd from the instant which is pointed by the cursor CRS, ie the minute 15 this example illustrated by FIG. IA. In this example, the Eq equipment does not restore the video from this moment until a user press on the CRS cursor is detected.
    During a step E200, the equipment Eq detects a movement mvt on the screen S by the user, more precisely along the time bar TL. Thus, the method of the invention is repeated from step E300.
    According to the direction of movement, the equipment Eq adjusts, during step E300, the start and the end of the time window FT.
    In this example, a downward movement of the screen S generates advancement in the video Vd, while an upward movement results in a backward movement in the video.
    Simultaneously with the movement of the user along the time bar TL, the equipment Eq displays images corresponding to the instants pointed by the cursor CRS.
    Assume that the user has performed an upward movement in a manner that the CRS cursor is pointing to the 27 th minute of the video Vd as shown in Figure IB. The duration of the FT time window being fixed at 30 minutes, the cursor being positioned in the center of the time bar, the start of the time window is shifted to the instant corresponding to minute 12 and the end is shifted to minute 42.
    During step E400, the location of the dashes corresponding to minutes 5, 10, 15, 20, 25 and 30 are offset as shown in Figure IB. New dashes corresponding to minutes 35 and 40 are displayed.
    During the step E500, Eq equipment obtains the video Vd from the 27 th minute which is pointed by the cursor CRS.
    In another mode, during step E400, the equipment Eq divides the new FT window, from its start (minute 12) to its end (minute 42), into segments of duration of 5 minutes each, and place dashes to mark the ends of its segments (ie minutes 17, 22, 27, 32, 37 and 42).
    FIG. 3 is a flowchart representing steps of a method for controlling the representation of multimedia content Vd on a touch screen S of equipment Eq, in accordance with a second embodiment of the invention.
    FIG. 4 presents a graphical interface of a software program Prog, in accordance with the invention, according to this second embodiment.
    In this second mode, the equipment Eq executes the program Prog, and the multimedia content Vd is a video broadcast live from a football match between two teams T1 and T2.
    BE2019 / 5700
    The process is implemented by the equipment Eq. A user of Eq equipment wants to watch the game as it is broadcast. Indeed, in this mode the reproduction of the video Vd is in live broadcast mode.
    During a step E100 similar to step E100 described with reference to FIG. 2, the equipment Eq displays a time bar TL on the right of the screen S.
    This time bar TL comprises a cursor CRS and two semicircles C1 and C2 which together represent the time window FT of a determined duration of the video Vd.
    Each semicircle Cl (respectively C2) relates to a team Tl (respectively T2).
    In this example, the cursor CRS is placed in the middle of the two semicircles Cl and C2 and it is not visible so as not to clutter the screen S and hinder the display of the video Vd; however a time indicator can be displayed. The pCRS position is presented in FIG. 4 by a dotted line. In this mode, the cursor position can be determined intuitively by the user experience.
    The equipment Eq displays on the screen S, a button B400 to reverse 10 seconds in the video Vd, a button B402 to pause the playback of the video Vd, a button B404 to resume playback, a button B406 to choose an angle of a broadcasting camera when the match is filmed by several cameras, a B408 button to display information and statistics relating to players and / or teams, such as biography, position, age and the number of goals scored by a player, a B410 button to access a discussion space concerning the Vd video such as a forum shared between the users who watch the match live on their equipment via the Prog program and a B412 button to access the parameters of the Prog.
    In this example, the duration of the video Vd is not known beforehand since the broadcast of the match is live. It is estimated, however, to be around 90 minutes.
    The part LV of the time window FT presented in FIG. 4 at the top of the time bar TL is hatched to indicate that the playback of the video Vd is done live, in live mode.
    During a step E300 similar to step E300 described with reference to FIG. 2, the equipment Eq adjusts the start and the end of the time window FT.
    In the example presented in FIG. 4, the duration of the time window FT is 25 minutes.
    During a step E400 similar to step E400 described with reference to FIG. 2, the equipment Eq divides the time window FT into segments of duration of 5 minutes each. Dashes are represented on the time bar TL to represent the corresponding moments at each 5 minutes.
    During a step E500 similar to step E500 described with reference to FIG. 2, the equipment Eq obtains the video Vd and reproduces it on its screen S.
    BE2019 / 5700
    For example, the equipment Eq initially obtains the video Vd from time 0 and restores it on the screen S from this time 0.
    In the absence of detection of a contact movement of the user on the time bar, the equipment renders the video Vd from time 0, without taking into account the position of the cursor. However, a time indicator can be displayed at the position of the pCRS cursor to inform the user of the instant pointed to by the CRS cursor.
    As the match is broadcast live, the Eq equipment initially displays a reduced time window whose duration increases as the live broadcast progresses, until reaching the previously adjusted duration, ie 25 minutes in this example. .
    Also, the Eq equipment initially displays segments of a few seconds which are subsequently adjusted with respect to the duration already broadcast to transform into segments of a few minutes until arriving at segments of the duration defined beforehand, that is to say 5 minutes in this example.
    During a step E600, the equipment Eq obtains d-Evt data representative of a significant event in the game: a goal for example. This data includes the nature of the event (a goal), the moment of goal scoring, the name of the T2 team that scored and the name of the PLAYER player who scored that goal.
    During a step E700, the equipment Eq then displays a marker B414 on the semicircle C2 relating to the team T2 on the time bar TL to indicate the instant of this goal. The location of marker B414 is determined according to the time of the goal and in proportion to the start and end of the FT time window.
    Similarly, other m-Evt markers are placed on the semicircle C1 to represent events relating to the team T1 and on the semicircle C2 to represent events relating to the team T2.
    It is conceivable that the equipment Eq readjusts the start and the end of the time window FT relative to the adjustment made during step E300 and / or lengthens (or decreases) the segments defined during the step E400 if there are m-Evt markers close enough (or distant) from each other so that the visual rendering is not optimized. Adjusting the start and end of the time window and the duration of the segments according to the markers allows a better distribution of these markers and a better visual rendering.
    The user can apply filters to the m-Evt markers displayed on the time bar, by pressing a B422 button.
    During a step E200 similar to step E200 described with reference to FIG. 2, the equipment Eq detects a movement mvt by the user on the screen S, more precisely along the time bar TL.
    The Eq equipment continues the live playback of the Vd video without taking into account the moment pointed by the cursor.
    BE2019 / 5700
    However, according to the direction of movement, the equipment Eq adjusts, during step E300, the start and the end of the time window FT. Only the markers which correspond to events taking place in the new adjusted FT window are displayed. The locations of the displayed markers are adjusted according to the instants of the events to which they correspond and in proportion to the start and the end of the new window displayed.
    As a result, the display of the time bar TL is modified according to the detected movement without affecting the reproduction of the video Vd on the screen S.
    In this example, as long as the video Vd is being obtained live, the location and the size of the hatched part LV on the time bar TL are not affected by the detection of the movement mvt.
    In this example, when a marker B414 is placed opposite the position of the cursor CRS, by the movement mvt of the user along the time bar TL, the equipment Eq enlarges the size of this marker B414, as as illustrated in Figure 4.
    When the user places a B414 marker in front of the CRS cursor, he can press the B416 button to send data corresponding to the event represented by this B414 marker to a correspondent. The sending can be carried out according to a method of the state of the art, via a link between the program Prog and another program which can be executed on the equipment Eq, for example an SMS messaging program, a program of 'sending mail, a messaging program on a social network, or a program for writing and / or sending comments.
    As a variant, when the user long presses on a marker B414, a button or a new graphical interface is displayed to allow the user to share with one of his correspondents data representative of the event represented by this marker B414.
    Also, by pressing the button B418, the user can add data representative of the event corresponding to the marker B414, to a list of events favored by the user.
    As a variant, when the user presses the button B418 (without the marker B414 necessarily being placed in front of the CRS cursor), data representative of the moment of the video Vd which is being restored and / or of the moment pointed by the CRS cursor are added to the user's favorite event list.
    In one embodiment, when adding an event to the list of favorite events, a graphic indicator m-fav (such as a heart or a star) is placed on the time bar to bring out the 'instant corresponding to this event.
    During a step E800, the equipment Eq detects a press by the user on the marker B414, of the double click type for example.
    During a step E900, the equipment Eq restores the video Vd from the instant represented by the marker B414.
    BE2019 / 5700
    As a variant, the equipment Eq restores the video during the step E900 upon detection (E800) of a single press or of a prolonged press on the marker B414.
    During a step E920, on detection of a press by the user on the button B404, the equipment Eq resumes the reproduction in live mode, of the last moment obtained from the video Vd broadcast live.
    The user can press a B420 button to select a part of the Vd video he wishes to view. In this example relating to a football match, this part may be the first or second half, or possibly an overtime or penalty shootout.
    At the end of the live broadcast of the match, and therefore when the equipment Eq obtains information indicating the end of the video Vd, the equipment Eq deletes the hatched portion LV from the time bar TL.
    The functions and characteristics described with reference to FIGS. 3 and 4, buttons B400, B402, B406, B408, B410, B412, B416 and B418, markers B414, m-Evt and m-fav may well be applied for a restitution in replay mode than in direct broadcast mode.
    In one embodiment, the button B404 makes it possible to advance by x seconds during a restitution in replay mode (replay).
    Other embodiments
    In one embodiment, when the equipment Eq detects (E200) a movement along the time bar involving an adjustment of the start and / or the end of the time window, the multimedia content is reproduced, directly, at from the moment of the multimedia content pointed to by the cursor, without any additional action by the user (such as pressing the CRS cursor or a B414 or m-Evt marker).
    In one embodiment, the position of the CRS cursor is not fixed. When the user clicks on a marker B414 for example, the equipment Eq positions the cursor CRS opposite this marker B414. This mode allows the user to restore the multimedia content Vd from the moment corresponding to the marker B414 on which he clicked.
    In one embodiment, the time bar has several cursors.
    In an embodiment relating to a rendering in direct (“live”) rendering of multimedia content Vd, the equipment Eq automatically adjusts the start and / or the end of the FT window so that the last moment obtained from the video Vd is visible on the time bar TL.
    The time bar can be adjusted as the multimedia content is rendered, with a visual effect simulating a rotation of the time bar according to a simultaneous adjustment of the start and end of the time window FT.
    BE2019 / 5700
    In an embodiment also relating to a live restitution, when the equipment Eq obtains data representative of a marking event, it displays a marker m-Evt next to the hatched part LV. The position of this m-Evt marker is changed as the automatic start and / or end of the FT window is automatically adjusted.
    In an embodiment also relating to a direct restitution of multimedia content Vd, according to a sense of a detected movement mvt, the hatched part LV is likely to disappear from the time bar. In this mode, the hatched part LV always follows the last moment obtained from the multimedia content Vd.
    In one embodiment, after obtaining (E600) data d-Evt representative of significant events, the equipment Eq adjusts (E300) again the start and the end of the time window FT and adjusts (E400 ) possibly segmentation of the FT window before displaying (E700) m-Evt markers on the TL time bar. This mode can be implemented for the rendering of multimedia content Vd in replay mode ("replay") or in direct playback mode ("live"). This mode is shown in Figure 3 by dotted arrows.
    In one embodiment, the button B422 presented in FIG. 4 allows the user to select filters and modify parameters of these filters, for example display only markers corresponding to “goal” type events, or display only markers relative to the Tl team, or display a maximum of 5 markers on the TL time bar, etc. The equipment Eq obtains the parameters of the filters selected by the user and adjusts, as a function of these parameters, the start and the end of the time window FT. Optionally, the equipment Eq also adjusts, based on these filter parameters, the segmentation of the time window FT to ensure better ergonomic rendering and better clarity of the markers m-Evt displayed on the time bar TL.
    In one embodiment, the multimedia content Vd can be considered as a set of several logical parts, for example a video of a football match comprises at least two parts corresponding to the two periods of the game. In other examples where the multimedia content is a video of a tennis or boxing match, the B420 button allows you to select the set or the round to be returned. The button B420 presented in FIG. 4 allows the user to go directly from one logical part to another without the need to perform a movement along the time bar TL. Upon detection of a press on the button B420, the equipment Eq automatically adjusts the start and the end and possibly the segmentation of the time window TL in order to move from one logical part of the content Vd to another.
    FIG. 5 shows two movements mvtl and mvt2 detected on the screen S according to one embodiment. According to this mode, the movements which can affect the adjustment of the time window FT and the reproduction of the multimedia content Vd, are only detectable by the program Prog if they follow exactly the shape of the time bar TL.
    BE2019 / 5700
    In another embodiment illustrated by FIG. 6, the screen S includes a tolerance zone TLR which includes the time bar TL. User movements can be detected in this TLR tolerance zone even when these movements do not exactly follow the rounded shape of the TL time bar.
    For example, a detected movement mvtl 'which has an origin located on or near the TL bar and which goes towards a point of coordinate lower than the origin is considered as a movement along the TL bar downwards, aiming to place the cursor on a later instant and adjust the beginning and the end of the FT window to advance them in the future. This movement mvtl 'is equivalent to movement mvtl presented in figure 5.
    The relationship between the direction of movement and the adjustment of the FT window can be different from the modes already described, for example, a movement down the TL time bar to adjust the start and end of the FT window for shift in the past.
    FIGS. 7A and 7B illustrate an embodiment in which the position of the time bar TL is automatically modifiable according to a language of text included in the multimedia content Vd.
    FIGS. 8A and 8B illustrate an embodiment in which the position of the time bar TL is automatically modifiable depending on whether movement of the user on the screen S is detected as movement made by the right hand or by the left hand.
    FIGS. 9A, 9B, 9C and 9D illustrate an embodiment in which the position of the time bar TL is modifiable automatically according to an orientation of the screen S. The program Prog obtains information representative of the orientation from another program executed on the Eq equipment, for example an accelerometer. In particular, when a screen is held in landscape, the time bar can be placed on one of its bottom corners, as illustrated in FIG. 9D.
    Figures 10A and 10B illustrate an embodiment in which parameters of the time bar TL can be modified by the user. For example, the shape of the rounded curve included in the TL bar can be modified upon detection of a movement of two fingers on the screen S after a configuration performed using the B412 button.
    In another mode, the spacing between two successive markers is modified on detection of a movement of two fingers on the screen S at the time bar.
    In another mode, the duration of the segments is modified on detection of a movement of two fingers on the screen S at the time bar.
    BE2019 / 5700
    FIGS. 11A and 11B illustrate an embodiment in which parameters of the time bar TL are determined as a function of the characteristics of the equipment Eq, for example its nature or the size of its screen. The time bar can contain a semicircle on one side of a screen of an Eql smartphone (figure 11A) and a quarter circle on a corner of a screen of a larger Eq2 tablet (figure 11B ). In another example, the time bar can contain a semicircle centered on one side of a smartphone screen and a decentered semicircle on one side of a screen (between the center and one of the two ends) a larger shelf.
