RELATED APPLICATION S

[0001] This application claims the benefit of Indian Patent Application No. 202041006309, filed on February 14, 2020, the content of which is incorporated by reference herein in its entirety.

BACKGROUND

[0002] The present invention relates to a system and a method for analysing a video stream. More particularly, the present invention relates to a sports analytics system and a method for analyzing a live video broadcast stream of a sporting event.

[0003] Broadcasting sporting events is a very common practice where spectators are able to experience the events which they missed to attend in person. This also enhances the potential viewership to a wider group of audience, thereby providing significant benefits for broadcasters, teams and sports franchises. Real-time contextual overlays for live broadcast feeds are traditionally done by inserting and presenting contextual information relevant with the potential viewers to augment viewership. However, for sporting events, it requires complex data tracking and analysis to present contextual interactive content in real-time to actively engage the audience with the live broadcast feed. Hence, there is a need for a system and method for analyzing the live video broadcast stream of the sporting event to deliver real-time contextual interactive content for the audience.

[0004] Real-time motion capturing and object tracking is indispensable when it comes to analyzing sporting events. The major aspect in analyzing the live broadcast feed of the sporting event is the recognition of the players in real-time by actively tracing and tracking the players over time to get meaningful insights before presenting it to the audience. Motion capture methods using optical systems, various sensors to measure three-dimensional (3D) location of the organs of the players and using various pattern recognition techniques are existing in the prior art. However, they require a complex system comprising an array of sensors and dedicated hardware to identify and locate the measurements accurately. Further, this makes it more difficult to perform analytics and deliver the contextual interactive content with accuracy in real-time on the live broadcast feed. Hence, there is a need for a system and method for analyzing the live video broadcast stream of the sporting event to recognize players in a multifaceted technique to deliver contextual interactive content for the audience.

[0005] In a sporting event, the scene is mostly dynamic as the players maneuver themselves alongside other objects based on the nature of the game and circumstances. The existing tracking technologies are inclined towards providing qualitative data on the players and objects but this requires sophisticated techniques and manual efforts to bring the contextual interactive content onto the live broadcast feed. However, the accuracy of the data is not certain and effective. Systems using numerous cameras, sensors and identifiers are used to fetch the useful information. However, these techniques require cumbersome solutions for performing analytics to extract the contextual interactive content from the acquired data which further increases the cost and time spent. Optical 3D measuring techniques fail to provide accurate data due to insufficient viewing angles and distortions as a result of dynamic images. Aforementioned drawbacks lead to aggravation of complications in performing analytics to retrieve useful insights and metrics. Hence, there is a need for a system and method for analyzing the live video broadcast stream of the sporting event to perform accurate sports analytics to deliver contextual interactive content with lot of insights and metrics for the audience.

[0006] The live events usually generate significant revenue for the broadcasting companies and advertisers. When live events such as sports are augmented with contextual interactive content, it will extend their business further followed by higher revenue generation. Sports teams perform lot of analytics to conduct studies on their players and their games to formulate strategies and decisions using extraction of accurate data and an advanced analytics module. Similarly, the broadcasting companies seek such techniques to augment the monetization potential of the live broadcast feed. The audiences for sporting events expect more engagement with the game and hence there is a need for a system and method for analyzing the live video broadcast stream of the sporting event to deliver more contextual interactive content in real-time. Traditional techniques require complex hardware for implementation and additional cameras either in the playing field/court or elsewhere are needed to capture the data which leads to expensive system requirements.

[0007] A live video broadcast stream consists of a series of frames. Frames per second (fps) indicates the number of frames that exist in a timeframe of 1 second. The duration of a single frame is referred to as frame persistence duration or frame duration (lOOOms/fps). For example, in a 25 fps video, each second will consist of 25 frames and each frame will persist on the screen for a total of 1000/25 40 ms. To provide contextual interactive content to the audience in real-time, all the processing activities should occur within this timeframe in order keep up with the live broadcast feed. Otherwise, by the time one frame is processed, subsequent frames will be lost. Hence, there is a long felt but unresolved need for a system and a method for analyzing the live video broadcast stream within the frame persistence duration or the frame duration.

[0008] Hence, there is a long felt but unresolved need for a system and a method for analyzing a live video broadcast stream of a sporting event to deliver contextual interactive content for the audience in real-time to enhance their viewership and augment the monetization potential of existing content for the broadcasting companies and advertisers.

SUMMARY OF THE INVENTION

[0009] This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to determine the scope of the claimed subject matter. [0010] The sports analytics system and the method disclosed herein address the above recited need for analyzing a live video broadcast stream of a sporting event to deliver contextual interactive content for the audience in real-time to enhance their viewership and augment the monetization potential of existing content for the broadcasting companies and advertisers. Furthermore, the sports analytics system and the method disclosed herein exploits the phase difference between real time messaging protocol stream and a hypertext transfer protocol live stream to complete the processing activities. The sports analytics system incorporates a computer server for analyzing a live video broadcast stream of a sporting event. The sport analytics system comprises a video demuxer, a non-transitory computer readable storage media, and at least one processor. The video demuxer receives the live video broadcast stream of the sporting event from a video capture device and splits the received live broadcast stream into a real time messaging protocol stream and a hypertext transfer protocol live stream. The non- transitory computer readable storage media stores computer program instructions defined by modules of the sport analytics system. The processor is communicatively coupled to the non-transitory computer readable storage media, and the processor is configured to execute the computer program instructions defined by the modules of the sport analytics system. An analytics module analyzes the real time messaging protocol stream within a predetermined time interval. The predetermined time interval corresponds to a phase difference between the real time messaging protocol stream and the hypertext transfer protocol live stream. The predetermined time interval is less than a frame persistence time of a frame. The analytics module comprises a detection module, a tracking module, a recognition module, a comparison module and a transmission module. The detection module detects one or more persons present in a frame of the real time messaging protocol stream, using one or more cues selected from a first set of cues comprising a facial detection, a head detection, a person detection, and a jersey number detection based on availability of the first set of cues.

[0011] The tracking module tracks the detected persons in the frame, by analyzing one or more preceding frames of the real time messaging protocol stream. The recognition module recognizes the tracked persons in the frame using one or more cues selected from a second set of cues comprising a facial recognition, a person recognition, a jersey recognition, a live score feed of the sporting event, and a commentary of the sporting event based on availability of the second set of cues. The jersey recognition comprises one or more of jersey number classification and team recognition. Individual weights are assigned to each of the facial recognition, the person recognition, and the jersey recognition when the facial recognition, the person recognition, and the jersey recognition are performed in the frame. The individual weights are determined based on clarity of each person recognized in the frame. If any of the facial recognition, the person recognition, and the jersey recognition is unavailable, the recognition module uses one or more of the live score feed and the commentary for the identification of one or more players in the frame. The comparison module identifies one or more players in the frame by comparing the assigned weights for each of the recognized persons with pre-existing data of all players. The transmission module transmits the hypertext transfer protocol live stream and analysis data comprising contextual interactive content of the identified players to a client application provided on a user device by the sports analytics system within the predetermined time interval. The live video broadcast stream is transformed into an interactive video comprising the contextual interactive content of the identified players. The client application comprises an interaction module for providing user interaction with the interactive video.

[0012] The contextual interactive content of the identified players is displayed on the user device without the contextual interactive content of the identified players overlapping existing graphics of the hypertext transfer protocol live stream. The contextual interactive content of the identified players comprises a dynamic display of one or more of a scorecard, a player information, and match statistics and the contextual interactive content of the identified players can be customized and shared on social media. The user can interact with one or more of the identified players in the interactive video. The sports analytics system augments the implementation of on-demand enhanced content by recognizing players of interest and displaying the key metrics of the recognized player such as player’s bio, season, career statistics, social media posts and related videos for the user device. The sports analytics system also provides rich content for users to see the head-to-head comparison of statistics of the players of interest. The sports analytics system further helps to engage the users with the live video broadcast stream by embedding game experience and augments the monetization potential of the existing content for various broadcasting companies and advertisers.

DETAILED DESCRIPTION OF THE INVENTION

[0032] FIG. 1 exemplarily illustrates a sports analytics system 100 incorporating a computer server for analyzing a live video broadcast stream of a sporting event. As used herein, “live video broadcast stream” refers to a live feed of a video broadcast of a sporting event. The sports analytics system 100 comprises a video demuxer 101, a non- transitory computer readable storage media 202, and at least one processor 201 as exemplarily illustrated in FIG. 2. The video demuxer 101 receives the live video broadcast stream of the sporting event from a video capture device (not shown) and splits the received live broadcast stream into a real time messaging protocol stream 101b and a hypertext transfer protocol live stream 101a. The real time messaging protocol stream 101b is routed to an analytics module 102 for analyzing the sporting event. The hypertext transfer protocol live stream 101a is encoded for broadcasting to any consumer device platforms such as a web, any iOS device, any android device, or other integrated platforms. Furthermore, an offset based frame synchronization logic is implemented to achieve frame level synchronization across the split streams. The non-transitory computer readable storage media 202 stores computer program instructions defined by modules of the sports analytics system 100. The processor 201 is communicatively coupled to the non-transitory computer readable storage media 202 and configured to execute the computer program instructions defined by the modules of the sports analytics system 100. The analytics module 102 analyzes the real time messaging protocol stream 101b within a predetermined time interval. The predetermined time interval corresponds to a phase difference between the real time messaging protocol stream and the hypertext transfer protocol live stream. The predetermined time interval is less than a frame persistence time of a frame. The analytics module 102 comprises a detection module 103, a detection/comparison queue 104, a tracking module 105, a recognition module 106, a comparison module 107, configuration data module 108 and a transmission module 109.

[0033] The detection module 103 detects one or more persons present in a frame of the real time messaging protocol stream 101b, using one or more cues selected from a first set of cues comprising a facial detection 103a, a head detection 103b, a person detection 103b, and a jersey number detection 103c based on availability of the first set of cues. As used herein, “jersey” refers to any type of garment worn by the persons in the frame. The sports analytics system 100 is capable of detecting the persons in the frame from various angles and orientations. The detection module 103 using a first set of pre-trained models 103d to detect various cues in the frame. The facial detection 103a comprises detecting faces of the persons in the frame and creating bounding boxes around the detected faces such that the faces are tightly cropped by the bounding box as illustrated in FIG. 4C. The person detection 103b comprises detecting bodies of the persons in the frame in various complex situations such as when the body of the person is either partially visible or fully visible, or when the body of the person overlaps with another person’s body. The person detection 103b comprises creating bounding boxes around all detected bodies of people in the frame as illustrated in FIG. 4A.

[0034] Similarly, the head detection 103b comprises detecting heads of the persons in the frame in situations like head either partially visible or head fully visible or head in various orientations and poses. For example, the person’s head may be seen from behind, from the front, from the bottom or top or from either side. In some cases the person’s head may overlap with another person’s head. The output of the head detection 103b comprises creating bounding boxes around all the detected heads in the frame. Each detected head is associated with a body and the bounding box is made as close to the head as possible and inside the associated person’s bounding box, as illustrated in FIG. 4B. The jersey number detection 103c comprises detecting jersey numbers on one or more of back, front, shoulders, and other locations on the jersey of the persons in the frame as illustrated in FIG. 4D. Furthermore, a jersey number detection 103c comprises detecting each digit on the jersey individually (even if they act as a part of a multi digit number) using a pre-trained model 103d. The hierarchy of the detection sequence is a face bounding box contained within a head bounding box which in turn is contained within a person bounding box as illustrated in FIG. 4E. The output of the detection module 103 is fed into a shared detection/comparison queue 104 for further processing.

[0035] The tracking module 105 tracks the detected persons in the frame, by analyzing one or more preceding frames of the real time messaging protocol stream 101b as illustrated in FIG. 5. The tracking module 105 associates the detected person across a contiguous collection of frames, essentially capturing the movement of that person. Furthermore, the tracking module 105 employs a hybrid tracking algorithm to track the detected persons in the frame using a multi-object tracking approach. The detected persons are tracked in the frame continuously in real-time and the frames are processed independently to identify numerous objects in the particular frame. The hybrid tracking algorithm implements a learning technique to track the detected persons using Kalman filter prediction 105a, feature tracking 105b and Intersection Over Union (IOU) 105c using a second set of pre-trained models 105d.

[0036] The recognition module 106 recognizes the tracked persons in the frame using one or more cues selected from a second set of cues comprising a facial recognition 106a, a person recognition 106b, a jersey recognition 106c, a live score feed of the sporting event 106d, and a commentary of the sporting event 106d based on availability of the second set of cues. The recognition involves processes such as classification, extraction of embeddings, computation of similarity features using metrics like cosine distance, square euclidean distance, etc. Each recognition has a confidence value associated with it and only if the confidence value of a predicted recognition exceeds a previously set threshold confidence value, the prediction is considered. This decreases the possibility of false positives, and makes the recognition more accurate.

[0037] The facial recognition 106a comprises extracting embeddings from a detected face and they are compared to another array of embeddings obtained from a previously collected static set of high resolution images as illustrated in FIG. 6A. The facial recognition 106a is based on similarity between the embeddings. Furthermore, parameters such as pose, size of face, colour of skin, and orientation towards camera do not affect the facial recognition 106a. The jersey recognition 106c comprises one or more of jersey number classification and team recognition. The jersey number classification is used to classify each of the detected digits of the jersey into one or more classes as illustrated in FIG. 6B. Furthermore, multiple digits that belong to the same jersey number are associated with each other based on either their relative position or font. The jersey number classification maintains a queue system to minimize the possibility of isolated cases of false positives. The team recognition comprises extracting embeddings from the person bounding box and comparing against an array of previously computed embeddings as illustrated in FIG. 6C. The team recognition uses jersey colour as the distinguishing parameter and performs recognition based on the similarity between the embeddings.

[0038] Individual weights are assigned to each of the facial recognition 106a, the person recognition 106b, and the jersey recognition 106c when the facial recognition 106a, the person recognition 106b, and the jersey recognition 106c are performed in the frame. The individual weights are determined based on clarity of each person recognized in the frame. The recognitions predicted by the recognition module 106 have an associated confidence measure based on which a final inference is made. Then the recognitions are then pushed to the detection/comparison queue 104 where the predictions with a low confidence measure are retained to reflect on future decisions. As used herein, “individual weights” refers to a score generated for the detection of one or more of the second set of cues. For example, the sports analytics system 100 actively recognizes the tracked persons in the frame of a live cricket video and assigns individual weights to each one of them depending on one or more of the second set of cues determined for the persons in the frame.

[0039] If any of the facial recognition 106a, the person recognition 106b, and the jersey recognition 106c is unavailable, the recognition module 106 uses one or more of the live score feed 106d and the commentary 106e for identifying one or more players in the frame as illustrated in FIG. 6D. The recognition module 106 uses a third set of pre defined models 106f to perform recognition. For example, when a player A exists in the frame wherein the jersey number is slightly occluded but the face is clearly visible, the weightage given to the “face recognition” is higher than that given to the “jersey number recognition”. On the other hand, when a player B exists in the frame wherein the jersey number is clearly visible and the face is slightly occluded, the weightage given to the “jersey number recognition” is higher than that of the “face recognition”. Furthermore, the sports analytics system 100 backfills the detections using player tracking. For example, if a person’s detection cues such as face detection 103a, and jersey number detection 103b, are not visible to provide enough confidence to uniquely detect the player at some point of time “t” in a particular track, but become available at some other point of time “t+n” in the same track, using backfilling and tracking, the system is able to identify the person throughout the extant of the track as illustrated in FIG 5.

[0040] The comparison module 107 identifies one or more players in the frame by comparing the assigned weights for each of the recognized persons with pre-existing data of all players. The detections, tracks, and recognitions, along with various confidence levels extracted from the detection module 103, tracking module 105 and recognition module 106 are fed into the decision/comparison queue 104. The sports analytics system 100 uses the extracted output from the independent modules to make the final inference to greatly reduce the false positives predicted to improve the system output. In terms of player recognition, each sport comprises its own characteristics in terms of markers available for the various modules to use in order to perform recognitions. For example, American Football players’ faces are not available as markers to recognize as the players wear helmets, while Golfers do not have numbers on their playing uniforms. So the system considers weights 107a of various available cues that are imperative in the context of recognition of sports players. In addition, the knowledge of previously made inferences 107b is also used to arrive at the final prediction and processed in an output monitoring unit 107c via a buffer 107d. [0041] The sports analytics system 100 processes the output from various modules and generates contextual interactive content within the predetermined time interval. The sports analytics system 100 exploits the phase difference between the real time messaging protocol stream and hypertext transfer protocol live stream to deliver contextual interactive content. The predetermined time interval is less than the frame persistence time of the frame. The sports analytics system 100 uses the inherent time-gap in order to service the additional time buffer required by its various modules. Furthermore, each module in the sports analytics system 100 can be configured with configuration data 108 via a network 110. The configuration data 108 could be at least one of machine learning models, game specific data, video/stream specific data, etc. Furthermore, the configuration data 108 can be updated in real-time during the processing of the real time messaging protocol stream 101b. In an embodiment, a dashboard is configured to control and monitor the processes performed by the sports analytics system 100.

[0042] The transmission module 109 of the sports analytics system 100 is configured to transmit the hypertext transfer protocol live stream and analysis data comprising contextual interactive content of the identified players to a client application 111a provided on a user device 111 by the sports analytics system 100 within the predetermined time interval. In effect the sports analytics system 100 transforms the live video broadcast stream into an interactive video comprising the contextual interactive content of the identified players and makes the interactive video available on the user device 111. The client application 111a comprises an interaction module 111b for providing user interaction with the interactive video. As used herein, “client application” refers to an application installed on the user device that is used for user interaction. Also, as used herein, “user device” refers to any device used for user interaction, but not limited to, mobile communication devices, cellular phones, personal digital assistants (PDAs), digital cameras, laptop computers, tablet computers, and netbooks.

[0043] The contextual interactive content of the identified players is displayed on the user device 111 without the contextual interactive content of the identified players overlapping existing graphics of the hypertext transfer protocol live stream. The contextual interactive content is transmitted as on-demand enhanced content to the live video broadcast stream in real-time to enhance the user interaction and increased viewership. The contextual interactive content of the identified players comprises a dynamic display of one or more of a scorecard, player information, and match statistics and the contextual interactive content of the identified players can be customized and shared on social media. The contextual interactive content of the identified players also includes information about the player, player statistics and player biography. The contextual interactive content of the identified players could be customized according to the requirements and optionally shared on any social media platforms. In some embodiments, the contextual interactive content of the identified players can be customized to a particular season and corresponding player statistics in that season. In another embodiment, one or more social media posts of the players and teams are provided as on-demand enhanced content. In another embodiment, head-to-head statistics of customized players are provided as rich content especially for the users to enhance their viewing interaction. The interaction module 111b provides rich content for the users in real-time, more engagement and a game experience platform for interested users and augments monetization potential of existing content for various broadcasting companies and advertisers. The user can interact with one or more of the identified players in the interactive video. As used herein, “user” refers to any end user of the application, for example, a sports fan watching a game on one of the aforementioned devices.

[0044] In an embodiment, the sports analytics system 100 provides recognition driven interactivity to enable viewers to get information about the identified players. The sports analytics system 100 allows the user to interact with the identified player on the screen of the user device. For example, the when a player is identified, visual cues such as an associated icon and/or marker is displayed on the screen such that the user is notified on the recognized player and thereby opening the gateway for interaction. The contextual interactive content is customized based on the detection of the cues to suit the requirements of the user. In another embodiment, the sports analytics system 100 allows the users to interact with more than one recognized player in the frame by notifying them with an option to choose the interested player from the identified players. For example, if multiple players are recognized at any point of time, an array of associated icons and/or markers are displayed so that the user is able to choose any player of interest for interaction.

[0045] The sports analytics system 100 provides user interactivity with and around the existing graphical assets in the hypertext transfer protocol live stream 101a. The sports analytics system 100 dynamically overlays the contextual interactive content layout around the graphics embedded in the hypertext transfer protocol live stream 101a. As used herein, “graphics” refers to any information such as scorecards, player statistics, player information, etc. displayed along with the hypertext transfer protocol live stream 101a. The sports analytics system 100 recognizes the co-ordinates of graphical assets on the screen that is part of the hypertext transfer protocol live stream 101a and ensures that the additional overlays do not overlap with each other so as to provide a good user experience. Furthermore, the sports analytics system 100 provides extensive information for the user as on-demand contextual interactive content on top of the overlaid graphics in the hypertext transfer protocol live stream 101a. For example, when a user clicks on the scorecard, an extensive version of the scorecard opens up to disclose a variety of information which was previously unavailable. Further, users can also interact and customize the extensive version of the scorecard such that the user will have access to a larger variety of on-demand contextual interactive content in real-time.

[0001] FIG. 2 exemplarily illustrates the architecture of a computer server employed by a sports analytics system 100 for analyzing a live video broadcast stream of a sporting event. The computer system 200 comprises, for example, a processor 201, a non- transitory computer readable storage medium such as a memory unit 202 for storing programs and data, an input/output (I/O) controller 203, a network interface 204, a data bus 205, a display unit 206, input devices 207, a fixed media drive 208, output devices 210, etc. The computer server 200 may optionally comprise a removable media drive 209 for receiving removable media. The processor 201 retrieves instructions for executing the modules, for example, 103, 104, 105, 106, 107, 108 and 109, of the sports analytics system 100 from the memory unit 202. [0046] FIG. 3 illustrates a method for analyzing a live video broadcast stream of a sporting event. The method disclosed herein employs a sports analytics system 100 comprising at least one processor 201 configured to execute computer program instructions for analyzing a live video broadcast stream of a sporting event. The sports analytics system 100 receives 301, using a video demuxer 101, the live video broadcast stream of the sporting event from a video capturing device. The video demuxer 101 of the sports analytics system 100 splits 302 the live broadcast stream into a real time messaging protocol stream 101b and a hypertext transfer protocol live stream 101a. The sports analytics system 100 analyzes 303 the real time messaging protocol stream 101b within a predetermined time interval. The predetermined time interval comprises a phase difference between the real time messaging protocol stream and the hypertext transfer protocol live stream. The predetermined time interval is less than a frame persistence time of the frame. The sports analytics system 100 detects 303a one or more persons present in a frame of the real time messaging protocol stream, using one or more cues selected from a first set of cues comprising a facial detection, a head detection, a person detection, and a jersey number detection based on availability of the first set of cues.

[0047] The sports analytics system 100 tracks 303b the detected persons in the frame, by analyzing one or more preceding frames of the real time messaging protocol stream. The sports analytics system 100 recognizes 303c the tracked persons in the frame using one or more cues selected from a second set of cues comprising a facial recognition 106a, a person recognition 106b, a jersey recognition 106c, a live score feed of the sporting event 106d, and a commentary of the sporting event 106e based on availability of the second set of cues. The jersey recognition 106c comprises one or more of jersey number classification and team recognition. Individual weights are assigned to each of the facial recognition 106a, the person recognition 106b, and the jersey recognition 106c when the facial recognition 106a, the person recognition 106b, and the jersey recognition 106c are performed in the frame. The individual weights are determined based on clarity of each person recognized in the frame. If any of the facial recognition 106a, the person recognition 106b, and the jersey recognition 106c is unavailable, one or more of the live score feed 106d and the commentary 106e is used for the identification of the one or more players in the frame. The sports analytics system 100 identifies 303d one or more players in the frame by comparing the assigned weights for each of the recognized persons with pre-existing data of all players.

[0048] The sports analytics system 100 transmits 303e the hypertext transfer protocol live stream 101a and analysis data comprising contextual interactive content of the identified players to a client application 111a provided on a user device 111 by the sports analytics system 100 within the predetermined time interval. Therefore, the live video broadcast stream is transformed into an interactive video comprising the contextual interactive content of the identified players. The contextual interactive content of the identified players is displayed on the user device without the contextual interactive content of the identified players overlapping graphics of the live video broadcast stream of the sporting event. The contextual interactive content of the identified players comprises a dynamic display of one or more of a scorecard, player information, and match statistics and the contextual interactive content can be customized for sharing on the social media. The user can interact with one or more of the identified players in the interactive video.

[0049] FIGS. 7A-7D exemplarily illustrates a screenshot of an on-demand enhanced contextual interactive content overlaid on a hypertext transfer protocol live stream 101a of a sporting event. The contextual interactive content is displayed without overlapping existing graphics displayed on the hypertext transfer protocol live stream 101a of the sporting event. As used herein, “contextual interactive content” refers to any on-demand enhanced content that is streamed onto the user device 111 in real-time to enhance the user interaction and increased viewership.
