    METHOD AND SYSTEM OF EMISSION IN CONTINUOUS OF MULTI-CAMERA EVENTS
    5 Technical sector
    The present invention relates in general, in a first aspect, to a method of continuous emission of multi-camera events, whose purpose is to show different video sequences in different viewing windows, and more particularly to a method comprising
    10 Automatically and dynamically change the video streams presented.
    A second aspect of the invention concerns a system of continuous emission of multi-camera events adapted to implement the method of the first aspect.
    15 State of the prior art
    Different methods of continuous broadcasting (ie "streaming") of multi-camera events are known in the state of the art.
    In particular, in the international application WO2015073924A1 a method is described comprising the steps included in the preamble of claim 1 of the present invention, ie:
    a) receive, on at least one computer server, individual video signals relating to
    25 an event and which are broadcast continuously from corresponding video sources that include multiple cameras, such as mobile cameras or mobile computing devices and / or fixed cameras;
    b) select at least some of said individual video signals, and configure them to
    30 that the video sequences of each of them occupy a respective display window of at least one screen when presented on at least said screen;
    c) continuously send information that includes said video sequences, from said computer server to at least one user computing device that includes
    35 at least one screen;


    d) at least presenting said computing device, continuously, on at least said screen, the video sequences received occupying different viewing windows; Y
    e) make, said user, a selection, through means of entry of said
    5 computing device, which implies that several required video sequences, relative to said or other event, which differ at least in part from those presented prior to said selection are presented in several display windows of at least said screen.
    In WO2015073924A1, multiscreen video signals are created on the computer server
    10 (called composite video signals) with the individual video signals, and a first of said multi-screen video signals is sent in step c) and, after selection in step e), a second of said multi-screen video signals , which has been previously created and stored in memory.
    15 That is, the user can only choose (implicitly or explicitly) between multiscreen video signals already created before their selection in step e), which makes the method proposed in WO2015073924A1 a static method of generating video signals that does not allow the dynamic generation of new multiscreen video signals in response to the user's selection (or in response to any other kind of action), but
    20 that simply offers the user the possibility to choose between multiscreen video signals already created.

    According to an embodiment example, the method proposed by the first aspect of the invention allows to implement any of the foregoing first, second and third main embodiments, either by selecting them manually, by a user, or, advantageously, in a manner automatic, depending on some pre-programmed criteria, such as the number of individual video signals to be presented in d) or in g). For example, if such a number is small, the second main embodiment example is automatically selected, since the bandwidth to be used for sending a few individual signals is not very high. On the other hand, if the number of individual video signals is too high to be sent separately, since they occupy a bandwidth that is too large or above the available one, then the first embodiment is automatically selected, that is, to combine the signals of Individual video in a single multi-screen video signal.
    In addition to the video signals, the method of the first aspect of the invention also comprises, for one embodiment, sending one or more individual audio signals.
    or combined, synchronized with those of video, and also selectable by the user of the computing device.
    The following embodiments or implementations of the method of the first aspect of the invention are applicable to the method when it is not limited according to any one of the three main embodiments set forth above, or when it is according to any of said three main embodiments , unless your link to a specific one of such main embodiments is explicitly indicated.
    For an exemplary embodiment, step b) comprises configuring the individual video signals so that one of the video sequences of one of them occupies a main screen display window and the rest secondary display windows, when presented the first multi-screen video signal on at least said screen.
    As regards step e) of the method proposed by the first aspect of the present invention, it comprises, for an exemplary embodiment, selecting one of the viewing windows.
    For the aforementioned case that one of the video sequences is displayed in a main viewing window and the rest in secondary ones, according to an example of


    embodiment, step e) comprises selecting one of said secondary viewing windows in order to require that the video sequence shown therein be shown in the main viewing window and that of the main viewing window being displayed in one of secondary display windows. In this case, the required video sequences differ from those previously presented at least in regard to the location and size of some of them, in particular those previously shown in the main window and the one shown therein after selection in e).
    For the first main embodiment, in response to said selection of one of the secondary display windows in step e), the method comprises performing step f1) or step f2).
    In the first case, that is, when step f1 is performed), the first multiscreen signal is modified so that the locations and sizes of the video sequences that respectively occupy the main and secondary display window selected are changed. , and in the case that stage f2 is performed), a second multiscreen video signal is created that produces the same effect, that is to say in the main window the video sequence that occupied the selected secondary display window and present in one of the secondary display windows that was shown in the main one, although such an effect is achieved by accessing the individual video signals again and creating the second multi-screen video signal from them, configuring and scaling them conveniently.
    Optionally, the method of the invention comprises automatically creating and superimposing, at least on said screen, at least one additional video sequence of another video signal, in response to a selection by the user carried out in the stage e) or in another stage.
    For another example of embodiment, step e) comprises selecting the realization of a virtual displacement of the display windows shown on said screen, in order to require the presentation, on at least said screen, of video sequences contained in windows of visualization contiguous to those initially shown but that are kept at least partially hidden before said virtual displacement, that is, what is known as a scrolling.


    According to a variant of said embodiment, applied to the one referred to above as the first main embodiment, the method comprises, in response to said selection of the realization of a virtual displacement, performing step f1). In this case, when the first multi-screen video signal includes all video sequences at
    5 show in the display windows, those initially shown and adjacent ones, step f1) comprises modifying at least one parameter that is interpreted by the computing device to make said presentation required, on at least said screen, of video sequences contained in the adjacent display windows.
    10 The effect achieved by the aforementioned "scrolling" is also applicable to step f2) as well as to any of two other main embodiments described above, either by presenting the required video sequences in the form of video signals individual or as part of a multi-screen video signal.
    For another example of embodiment, step e) comprises selecting, by the user, at least one of the following options: - visualizing the same event but for a previous time interval; -View the same event but changing at least some of the video sources; -View another event.
    20 When step e) comprises selecting to display the same event but changing at least some of the video sources, said selection is carried out based on, for example, at least one of the following criteria: quality of the video signals, geographical location of the cameras that constitute the video source, type of signal content
    25 video, and delay in receiving video signals.
    Advantageously, in each of the stages b) and f) the method of the first aspect of the invention comprises carrying out an automatic realization by at least the computer server.
    30 Said automatic realization includes, for an exemplary embodiment, synchronizing the individual video signals, either to broadcast them individually to the computing device or the intermediate computing entity or to include them in the multi-screen video signal (the first, the second and / or any other additional that may be created).


    According to another embodiment, said automatic embodiment comprises applying in each of the stages b) and f) a filtering of the individual video signals to modify them before selecting them or deciding whether or not to select them.
    5 According to various non-exhaustive examples, said filtering is based on at least one of thefollowing criteria: detect, in order to hide, children's faces, detect fragmentsvideo signals that do not correspond to the general theme of most signalsvideo received, detect the geographic location of the cameras associated with the signalsof video received, and select the video signals associated with cameras that best
    10 comply with a series of parameters pre-programmed or indicated by a user.
    For example, if the multi-camera event is a football match, the aforementioned filtering allows hiding the faces of children, as well as cameras (mobile or fixed) whose geographical location does not correspond to the interior of the football stadium, or, when, it's a race, lets
    15 select the cameras closest to the goal, when the runners are already reaching it.
    In the present invention, "computer server" means a computer or network of interconnected computers, locally and / or remotely, via cable and / or wirelessly.
    In general, the method is applied to a plurality of computing devices of different users, the steps e) to g) being carried out for each user, in a personalized manner, depending on the selection made by the user in step e) .
    25 Depending on the exemplary embodiment, the display windows are shown in different regions of the same screen or displayed on two or more screens, in at least one display window per screen.
    The method of the present invention is particularly advantageously applicable to the
    30 Continuous emission of multi-camera events to a plurality of computing devices, at least steps e) to g) being carried out in a personalized manner for each personalized computing device or for each group of computing devices of the same user. In this case, steps a) to d) are also carried out for the plurality of computing device, in order to transmit the multi-camera event to all of them, of
    35 according to any of the embodiments described herein.


    Advantageously, the method proposed by the first aspect of the invention comprises, by the computer server or the computing device or other computer entity interconnected with both, storing, storing in memory the individual video signals received in a) temporarily labeled and identified by the source of
    5 video from which they come, in order to use them in stage f). It gets so whenthe user in step e) makes a selection that involves accessing video sequences andpast, they are easily accessed by properly labeled memory, andcan be sent to be displayed on the screen of your mobile device.
    The realization of the different stages of the method proposed by the first aspect of the invention implies the use of suitable hardware and software. As regards the software, it is proposed that at least part of the functions performed by the computing device be carried out in a video player computer program, popularly known as "player". In this case, step e) is carried out by interacting the user
    15 with said "player", according to conventional functions such as rewind or advance, but which involve the unconventional realization of the steps explained above, that is to say access to video sequences required when making the selection, stored in memory, and sending thereof in the form of individual video signals or a multiscreen video signal formed therefrom.
    In any case, the method proposed by the first aspect of the invention is not limited to any name, number or types of computer programs to implement the functions thereof.
