Definitions

  • This invention relates to electronic devices for inserting images into live video signals, particularly to such systems adapted to be capable of rapidly inserting different indicia into video dependent on some event which may or may not be related to the video content, such as, but not limited to, the speed of the pitch in a baseball match, or the current value of a stock market index.
  • Sports broadcasters are constantly looking for ways to make television sports viewing more compelling to viewers.
  • One way to enhance a viewer's enjoyment of a game or contest is to provide statistics about the game such as, but not limited to, the current score; the time elapsed, the time of the game remaining; the speed an object is thrown, hit or served; the distance a ball or object is thrown, hit or served; the time taken for an object or player to move from one point to the next; the distance a football team has to go to achieve a First Down; the current position of an Offside Line in soccer; and so on.
  • a statistic in a reasonable time e.g., clock, stop watch, radar or JUGGS gun, a GPS position measurement, a marker that can be observed automatically or by a person, etc.
  • Such information is routinely displayed in television broadcasts as a static or animated overlay by means of such well-known keying devices as the Chyron Corporation's INFINIT® family of character generators.
  • the problem with adding in an overlay is that the video image becomes cluttered - and rather than enhancing a viewer's enjoyment of a game, too much information presented overlaid over the video of the game begins to diminish the viewing experience. In particular, such overlays can obscure some of the action of the game.
  • the preferred embodiment of the invention uses a modified live video insertion system to display the information not as an overlay but in a way that the inserted information indicia looks as if it is actually part of the original scene being televised. In this way the sports fan sees the game action with the added statistical information looking like a scoreboard or sign in the stadium itself. Most importantly, by displaying the additional information in the background, if the action of the game moves into that region of the image, the viewer sees the players and the action moving in front of the inserted information.
  • Alternative embodiments of the present invention permit displaying the information indicia in a manner in which it is obviously not part of the original scene being televised, similarly to the conventional manner depicted in Fig. 2.
  • this alternative embodiment displays the information indicia in the background so that action occurring in the game occludes it.
  • Further alternative embodiments rather than performing occlusion of the information indicia, resize or reposition the insert so as to avoid the game image from being obscured.
  • a still further alternative embodiment would simply disable the event information display when it would otherwise obstruct the TV audience's view of the event action.
  • the inserted indicia were static images, pre-prepared animation sequences or live video from another video source. Modifications to such systems are necessary to display information that only becomes available while the insertion is already in view, such as the outcome of a play being shown.
  • the technical problem that is solved by this invention is to transition from an insert that is of a scoreboard or sign to a display of that scoreboard or sign with one of a number of possible outcomes of a play or action, while showing the play or action.
  • the live video insertion system either inserts a live shot of a camera trained on a scoreboard displaying the pitch speed or runs a short animation, changing or morphing from the scoreboard or sign to a rendering of the scoreboard or sign displaying the measured speed of the pitch and then morphing or changing back to a rendering of the original scoreboard or sign.
  • Another, slightly more manageable way to implement this invention is to modify live video insertion systems by adding on a random access video storage unit, such as the well-known line of AVID Inc.'s video storage devices. If this random access video storage device is supplying video to be inserted, and the random access device has a multitude of different versions of an animation of the scoreboard or sign, one of which shows one of the possible outcomes to be shown, then all the operator has to do is to select and activate the correct animation sequence into the live video insertion system unit on cue. In the baseball speed of the pitch example, the random access video storage unit would need to have thirty different animations stored, one showing each of the possible speeds from 70 to 99 mph as the mid point of the animation.
  • a more elegant way to implement the invention is to use simpler, multi threaded animations, in which there is a core sequence with a number of optional mid sequence variations, each of which may be a short animation or may be as simple as a single animation frame. For instance one implementation of the baseball speed of the or current score of another game or other information that the viewer would like to see without being distracted from the flow of the game they are currently watching.
  • Fig. 1 is a schematic representation of a conventional live video insertion system.
  • Fig. 2 illustrates a video scene in which additional information has been conventionally overlaid onto the video.
  • Fig. 3 illustrates a video scene in which additional information has been added into the scene via the preferred embodiment of the present invention.
  • Fig. 4 is a schematic representation of a multi-threaded animation sequence.
  • Fig. 5 is a schematic representation of a multi-threaded animation sequence in which the mid-sequence variations are a single animation frame.
  • a video transmission which may, for example be a live television broadcast of an event being played on field 10, is captured for remote viewing by television cameras 12, and is composed into a program for viewing within a standard video production unit 14, which may be a television production truck or a video studio, equipped with well known video production equipment.
  • a standard video production unit 14 which may be a television production truck or a video studio, equipped with well known video production equipment.
  • the video is fed through a live video insertion system 16.
  • the live video insertion system unit 16 performs the functions of recognition using the recognition unit 18, tracking using the tracking unit 20, occlusion mask production using the occlusion mask production unit 22 and then pitch display has a core sequence which shows a flat sign rotating to reveal what is on the back of it.
  • Each of the mid sequence variations is a single field showing the back of the sign with one of the thirty possible pitch speeds. Instead of 30 animation clips, a single main animation with thirty, one-field mid sequence variations is all that is required. Such an animation is sufficiently small that it can be stored in the internal random access memory of a live video insertion system unit, and be under direct control of that system's operational software, making it not only less expensive, but also simplifying the synchronization and timing issues.
  • One intended use of live video insertion systems is to create virtual billboards in the broadcasted video signal.
  • One of the paradox's of the virtual billboard function of a live video insertion system is that, to the television audience, it inserts artificial or virtual signage into video images in a way that makes the sign look as if it really is part of the stadium or venue from which the broadcast is being sent.
  • it is desirable to draw attention to the insertion in order to make the insertion more valuable to the advertiser.
  • One way to do this is to make the insertion appear to be an animated object, such as, but not limited to, a rotating sign. The motion of such a moving sign draws viewer's attention to the insertion. Broadcasters and sports fans, on the other hand, find such arbitrary motion distracting from the game.
  • An additional benefit of the present invention in which a live video insertion system is used to display sports information is that it increases the value of the signage for the advertiser. Making the sign animate in such a way that it displays information that is linked to the game, and adds to the understanding or enjoyment of the game satisfies both the advertiser's desire for visibility and the broadcaster/sports fan wanting to enhance the game.
  • the recognition and tracking parameters may also be provided by sensors 13 attached to the camera itself, and interpreted by a camera head data interpreter 15, as used by some virtual reality studio systems, and as discussed in co-pending U.S. Patent application Serial No. 09/ entitled "IMAGE INSERTION IN VIDEO STREAMS USING A COMBINATION OF PHYSICAL SENSORS AND PATTERN RECOGNITION", the teachings of which are hereby included by reference.
  • a viewer watching the broadcast on a well known television set 28 will see the image of the game 30 into which the inserted indicia 32 has been placed to look as if it really is in the stadium, and which changes size, shape and position appropriately as the image of the game 30 is panned, zoomed and otherwise altered in perspective, and is properly occluded by players or other objects from the game moving in front of it.
  • a television video image 40 of a sporting event has a graphic overlay 42 showing current game statistics, which may be the current score, a graphic overlay 44 showing the state of play, which may be a graphic indicating the position of players on the field, and a graphic overlay 46 showing the speed of the pitch.
  • current game statistics which may be the current score
  • graphic overlay 44 showing the state of play
  • graphic overlay 46 showing the speed of the pitch.
  • a television video image 40 of a sporting event has extra information displayed on an live video insertion system insert 48, which appears to be a sign board attached to the stadium back wall.
  • This insert 48 moves and adjusts size and shape to maintain the illusion that it is part of the back wall as the television video image 40 is panned, zoomed and otherwise adjusted.
  • This insert 48 is also properly occluded, meaning that when players, or other objects in the game, move in front of it, the insertion 48 allows the players or objects to be displayed in their entirety, exactly as if the player or object has really moved in front of the sign.
  • This occlusion of the live video insertion system's insert 48 is what allows the extra information to be conveyed to the fan while minimizing the disruption of the viewing experience.
  • Another, slightly more manageable way to implement this invention is to modify the live video insertion system by adding on a well known random access video storage unit, such as one of AVID Inc.'s video storage devices. If this random access video storage device is supplying video to the live video insertion system, and the random access device has a multitude of different versions of an animation of the score board or sign, one of which shows one of the possible outcomes to be shown, then all the operator has to do is to select and activate the correct animation sequence into the live video insertion system on cue. There are technical difficulties and costs associated with this simple implementation of the invention. In particular, having a large number of complete animations on such an external storage device is expensive in memory, and introduces timing and synchronization difficulties.
  • a well known random access video storage unit such as one of AVID Inc.'s video storage devices.
  • the multi-threaded animation 50 consists, in general, of a core start sequence 54, a number of mid sequences 56, 58 and 60 and an end sequence 62, all of which are made up of a sequence of individual video frames 52.
  • the mid sequence animations 56, 58 and 60 represent the possible outcomes of the event being broadcast.
  • One way in which the system works is by having the first frame 64 as a static animation, which may represent a score board or an advertising sign, or any other suitable object for showing the added information on.
  • the live video insertion system operator activates, via the usual live video insertion system control interface, the animation — selecting the appropriate mid- sequence animation. For instance if the kick is good, the selected animation would start at the first frame 64 of the core start animation sequence 54 and run through, displaying each frame 52 of the core start animation sequence 54 for a predetermined time which may be as short as a single field of video.
  • the core start animation sequence 54 may, for instance, represent a signboard rotating to reveal the other side.
  • the animation then jumps to one of the of mid sequence animations 56, 58 and 60 that has been determined or chosen as being appropriate for the kick being good. If the kick were bad, or a two-point conversion was scored, then the appropriate mid sequence animation would be chosen instead.
  • the animation then jumps to the first field 72 of the core end animation sequence 62 and runs through, displaying each of the animation frames 52 for a predetermined length of time, until it reaches the end frame 74 of the core end animation sequence. 10
  • the key idea of the multi-threaded animations 50 is that the total number of animation frames is kept relatively small even if there are a large number of mid - sequence animations. By keeping the total animation small, it is possible to have all the animation frames stored in memory as part of the logo 24 of the live video insertion system. For instance a current version of live video insertion system used in live broadcast by the assignee of the present invention, PVI Inc., has sufficient memory to store forty 120 by 90 pixel full color images with attached keys. Having the complete set of possible animations stored on such an internal memory significantly reduces the cost of the system and makes control of it significantly easier.
  • the mid-sequences 56, 58 and 60 can be created after the event related information is captured. They may even be created while the core start sequence 54 is being displayed. This results in an even greater saving of computer memory.
  • the appropriate mid-sequence animation 56, 58 or 60 may be created in its entirety or by compositing critical information, such as the digits representing a speed or other statistic, onto a pre-rendered image or animation sequence.
  • multi-threaded animations 50 can be implemented in many different ways, including but not limited to, having the initial insertion displayed be an animation sequence, comprising the core start animation sequence 54 frames, which are displayed sequentially in a continuous loop, until such time as the operator or the system calls for a jump to one of the of mid sequence animations 56, 58 and 60 that is appropriate for action that has just occurred, or information that has become available.
  • the possible statistics about the game that may be displayed by such a multi- thread animation of the preferred embodiment of the present invention include, but are not limited to, the current score, the time elapsed, the time of the game remaining, the speed an object is thrown, hit or served, the distance a ball or object is thrown, hit 11
  • a second example will serve to illustrate more fully the advantages of the multi-threaded animation 50 of the present invention.
  • a baseball game it is of interest to viewers of the game to be able to see the speed of the pitch. Since a reasonable baseball pitch in a major league game can be anywhere from 70 to 99 miles per hour, there are 30 possible outcomes, one of which has to be selected within a fraction of a second by an operator and displayed.
  • the core animation sequence 54 is a ten frame animation used both as a start and end core animation sequence
  • the set of mid sequence animations 84 consists of thirty single-field animations, each one corresponding to one of the possible pitch speeds of interest in a major league broadcast, the entire multi-threaded animation is only 40 fields.
  • the set up illustrates the tremendous compression achieved by the multithreaded animation 50.
  • Such a set up could obviously be adapted to either show information other than the speed of the pitch in a baseball game, or to show similar information in a variety of other sports broadcasts.
  • One way the baseball speed of the pitch would work, is to have frame 80, the first frame of the core animation sequence be displayed as a normal inserted indicia of a live video insertion system onto the back wall behind a batter.
  • This inserted indicia, frame 80 which is the scoreboard or sign where the speed of the pitch will be displayed, is positioned so as to be in the field of view in a usual camera shot of the event.
  • a radar gun such as the well known JUGGS gun
  • the insertion unit 26 causes the core animation sequence 54 frames to be displayed as the insert, beginning with the start frame 80 and running to the end frame 82, showing each of the intermediate animation frames 52 in turn for a predetermined number of video fields.
  • the animation that this results in being displayed as the live video insertion system's insertion may for instance be an image of a scoreboard or sign changing or morphing in a particular fashion, such as, but not limited to be a sign rotating round to reveal the back of the sign.
  • the final frame 82 of the core animation sequence 54 may represent the back of the sign but with nothing on it.
  • the next frame displayed is then one of the thirty single frames of the set of mid sequence animations 84, each of which displays the back of the sign with a number corresponding to a pitch speed, in miles per hour, from 70 to 99.
  • This frame is displayed for a predetermined, operator variable, number of fields, after which the insertion unit 26 causes the final frame 82 of the core animation sequence 54 to be displayed.
  • the animation then runs backward to the start frame 80, showing each of the intermediate animation frames 52 in turn, but in reverse order to which they were originally shown, for a predetermined number of video fields.
  • the animation that this results in being displayed as the live video insertion system's insertion may for instance be an image of a scoreboard or sign changing or morphing in a particular fashion, such as, but not limited to be a sign rotating from revealing the back of the sign round to the sign itself.
  • the overall effect of such an animation is of a sign rotating round to reveal the speed of the pitch on the back, then rotating back again to the original sign.
  • the invention makes the information look as if it is part of the original video.
  • intelligence from the live video insertion system to include data obtained from camera sensor devices
  • the animation or graphic displaying the event related information may remain in a 13
  • this intelligence may be used not to provide occlusion, but to resize or reposition the insert so as to avoid event action being obscured. In yet another alternative embodiment this intelligence may also be used to simply disable the event information display when it would otherwise obstruct the TV audience's view of the event action.

Abstract

La présente invention concerne un système et un procédé d'insertion d'informations liées à des événements dans une retransmission vidéo de sorte que les informations ajoutées n'interfèrent pas l'action primaire intéressante dans la retransmission ou ne l'occultent pas. On peut diffuser les nouvelles informations en faisant appel aux instructions d'un système de rassemblement d'informations sur les événements pour déclencher l'affichage d'une animation pré-interprétée sélectionnée parmi une série d'animations pré-interprétées dans la retransmission vidéo via un système (48) bien connu d'insertion vidéo directe. La séquence d'animation selon l'invention comprend au moins deux parties (dessin 4), à savoir une séquence centrale ou de base (54) qui est toujours utilisée et une séquence moyenne ou variable (56, 58, 60) qui est modifiée en fonction des données réelles devant être affichées. On peut utiliser les données et le traitement du système (48) d'insertion vidéo directe pour effectuer une occlusion et/ou une poursuite soit pour que les informations sur les événements paraissent faire partie de la scène, ou tout simplement pour occulter l'écran dans le cas où les actions de l'événement seraient autrement occultées, ou pour éteindre ou repositionner ou changer les dimensions de l'écran dans le cas où les actions de l'événement seraient par ailleurs occultées.
