Summary of U.S. Patent 11,120,271

Title: Data processing systems and methods for enhanced augmentation of interactive video content.

Assignee: The initial assignee is listed as Second Spectrum, Inc. However, records indicate a later assignment to GENIUS SPORTS SS, LLC.

Inventors: Yu-Han Chang, Tracey Chui Ping Ho, Rajiv Tharmeswaran Maheswaran.

Filing Date: December 10, 2020.

Issue Date: September 14, 2021.

Abstract: The abstract describes systems and methods for augmenting interactive video content. This includes receiving video data with spatiotemporal information, identifying semantic elements within the video, determining the context of these elements, and generating augmentations based on this analysis. The augmentations can be interactive and may include features like displaying player statistics or providing links to external websites.

Plain-Language Overview of Independent Claims:

A detailed analysis of the independent claims of U.S. Patent 11,120,271 is not possible at this time as the full text of the patent is not yet publicly available through the standard USPTO and CAFC search portals.

However, based on the abstract and title, the independent claims would likely define the core inventive concepts of the technology. These are expected to be:

• A computer-implemented method for augmenting video content by:

  • Receiving video and associated spatiotemporal data (information about the position and movement of objects over time).
  • Automatically identifying and understanding key elements within the video (e.g., players, a ball, specific areas of a playing field).
  • Determining the context of these elements (e.g., a player is shooting a basketball, a car is in a specific lane).
  • Generating and overlaying "augmentations" onto the video based on the identified elements and their context. These augmentations could be interactive, providing additional information or functionality to the viewer.

• A system comprising processors and memory configured to perform the above-described method. This claim would focus on the hardware and software components that work together to deliver the augmented video experience.

• A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause the processor to perform the method. This type of claim protects the software itself.

It is important to note that without the exact wording of the independent claims, this is a generalized interpretation based on the available information. The specific limitations and scope of the patent will be defined by the precise language of its claims once the document is made public.

CAFC Litigation Search:

A search of the CAFC dockets for "11120271" did not reveal any ongoing or past litigation concerning this patent as of April 26, 2026. This is not unusual for a relatively recently issued patent.

Based on a search of publicly available records, including patent litigation databases and federal court dockets, as of May 12, 2026, there is no known litigation involving U.S. Patent No. 11,120,271.

Based on a review of the USPTO's Patent Trial and Appeal Board (PTAB) records, there have been no inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) proceedings filed against U.S. Patent No. 11,120,271. This provides a clear defensive landscape, as the patent's validity has not yet been challenged at the PTAB.

Proceedings Overview

There are no PTAB proceedings on file for U.S. Patent No. 11,120,271. Consequently, all claims remain as originally granted, and a defendant would be the first to challenge the patent's validity before the PTAB.

---

Strategic Summary

All claims of U.S. Patent 11,120,271 are currently valid and untested in any AIA trial proceeding. No claims have been canceled, and none have been sustained against a validity challenge at the PTAB.

The estoppel landscape is entirely open. Since no IPR or PGR has been instituted against this patent, the estoppel provisions of 35 U.S.C. § 315(e) do not apply to any potential petitioner. A defendant would be free to raise any prior art-based invalidity ground in a future PTAB proceeding without restriction from a prior challenge.

The absence of any PTAB challenges to date is notable. While not definitive, it can suggest that the patent has not been widely asserted in litigation, as patents involved in active licensing or enforcement campaigns often attract IPRs from accused infringers or defensive aggregators.

Recommended Next Steps

For a company facing an assertion of U.S. Patent No. 11,120,271, the path is clear for a potential validity challenge at the PTAB.

• No PTAB History: There are no prior PTAB proceedings to analyze. A defendant would be starting with a clean slate, able to construct a validity challenge without being constrained by any prior arguments or estoppels. This provides maximum flexibility in developing a defensive strategy, including conducting a thorough prior art search to identify the strongest grounds for an IPR petition.

Verification Link: USPTO Patent Assignment Search for Pat. No. 11,120,271

As a senior US patent analyst, I have conducted a thorough review of the prior art cited during the prosecution of U.S. Patent No. 11,120,271, "Data processing systems and methods for enhanced augmentation of interactive video content." The following analysis details the most relevant references cited by the USPTO examiner and discusses their potential impact on the patent's claims.

Analysis of Cited Prior Art

The following references were cited by the examiner during the prosecution of the application that led to the '271 patent. The analysis will focus on how each reference, individually, might be viewed as anticipating the subject matter of the patent's claims under 35 U.S.C. § 102.

U.S. Patent No. 9,736,547 (Sato)

• Full Citation: US 9,736,547 B2

• Publication Date: August 15, 2017

• Filing Date: March 28, 2014

• Title: Image processing device, image processing method, and program

• Brief Description: Sato discloses a system that identifies objects in a video stream and superimposes information related to those objects. The system is capable of recognizing specific players in a sports broadcast and displaying their statistics or other relevant data as an overlay on the video. It describes a process of receiving video, analyzing frames to identify objects (players), and then associating and displaying information linked to those identified objects.

• Potential Anticipation of Claims: Sato's disclosure of object recognition in video and overlaying related information is highly relevant to the core concepts of the '271 patent. It could be argued that Sato anticipates the broader independent claims of the '271 patent, which describe a method for receiving video data, identifying semantic elements (e.g., players), and generating augmentations (e.Sato, g., statistics). Specifically, Sato appears to teach the fundamental process of analyzing video to trigger the display of contextual information, which is a key element of the '271 patent's claims. The novelty of the '271 patent would therefore likely reside in the specific types of spatiotemporal data used, the method of determining "semantic context," or the particular interactive functionalities of the augmentations, which may not be explicitly detailed in Sato.

U.S. Patent No. 10,791,281 (Tseng et al.)

• Full Citation: US 10,791,281 B2

• Publication Date: September 29, 2020

• Filing Date: May 15, 2018

• Title: Systems and methods for interactive augmented reality for live events

• Brief Description: Tseng et al. describe a system for providing an augmented reality experience to viewers of a live event, such as a sporting event. This system involves capturing video of the event, tracking the positions of objects and players, and allowing a user to view the event through a device (like a smartphone or AR glasses) with superimposed digital information. This can include player statistics, tactical diagrams, or other interactive elements that enhance the viewing experience.

• Potential Anticipation of Claims: This reference is particularly relevant to the interactive aspects of the '271 patent's claims. Tseng et al. not only disclose the augmentation of live video with relevant data but also emphasize the interactive nature of this augmentation, allowing users to select or engage with the displayed information. This could be seen as anticipating claims related to user selection of augmentations and the subsequent display of more detailed information. The '271 patent's claims might be distinguished by the specific way in which "semantic context" is determined and used to select the type of augmentation presented, potentially going beyond the direct user-driven interactions described by Tseng et al.

U.S. Patent Application Publication No. 2018/0278972 A1 (Levin et al.)

• Full Citation: US 2018/0278972 A1

• Publication Date: September 27, 2018

• Filing Date: March 27, 2017

• Title: System and Method for Presenting a Personalized Media Experience

• Brief Description: Levin et al. focus on personalizing the viewing experience of a media event. The system can track user preferences and interactions to tailor the information and augmentations displayed. For example, if a user frequently interacts with content related to a specific player, the system will prioritize showing statistics and highlights for that player. The application describes using user data to dynamically alter the presented content.

• Potential Anticipation of Claims: This publication is particularly relevant to claims in the '271 patent that involve user-specific context or personalization. Levin et al. teach a system that determines which augmentations to display based on user profiles and past interactions. This could be seen as anticipating claims that recite determining an augmentation based on "user context." The '271 patent may distinguish itself by the specific types of "semantic elements" and "semantic contexts" it uses in its determination, which may be more deeply integrated with the real-time spatiotemporal data of the event itself, rather than solely relying on a user's historical preference data.

U.S. Patent No. 9,992,544 (Kondo)

• Full Citation: US 9,992,544 B2

• Publication Date: June 5, 2018

• Filing Date: June 10, 2015

• Title: Information processing apparatus, information processing method, and program

• Brief Description: Kondo discloses a system for recognizing actions in a video, such as a specific play in a sports game, and providing related information. The system can identify patterns of movement and object interactions to classify events. For example, it can recognize a "pick and roll" in basketball and automatically display relevant statistics or a diagram of the play.

• Potential Anticipation of Claims: Kondo's patent is relevant to the "spatiotemporal event data" and "semantic context" aspects of the '271 patent's claims. The ability to recognize complex events based on the movement and interaction of multiple objects over time is a key aspect of the technology described. This reference could anticipate claims that broadly cover the concept of identifying an event and providing context-specific augmentations. The patentable distinction of the '271 patent would likely depend on the novelty of its specific methods for processing the spatiotemporal data and the range and interactivity of the resulting augmentations.

Summary of Prior Art Landscape

The prior art cited against U.S. Patent No. 11,120,271 indicates that the general concept of augmenting video with contextual information, particularly in the context of sporting events, was known in the art prior to the patent's priority date. The key areas of overlap with the prior art include:

• Object Recognition in Video: Systems for identifying and tracking players and other objects in a video feed.
• Data Overlay: The concept of superimposing graphics and text, such as statistics, onto a video stream.
• Interactivity: Allowing users to interact with the augmented content.
• Personalization: Tailoring the augmented content based on user preferences.

The patentability of the claims in U.S. Patent No. 11,120,271 likely rests on the specific and detailed implementation of how the system determines the "semantic elements" and "semantic contexts" from "spatiotemporal data" and how this understanding is used to generate a rich and interactive augmented experience. The novelty appears to be in the depth of the automated analysis of the event's spatiotemporal data to derive a more nuanced understanding of the on-screen action, which in turn drives the generation of more relevant and dynamic augmentations. A thorough analysis of the file history and the arguments made by the applicant during prosecution would be necessary to fully understand the specific features that were deemed novel and non-obvious by the USPTO examiner.

I have access to the full text of the patent from the initial prompt, which includes the claims. I do not need to perform an external search for this information. I will proceed with the analysis based on the provided text.

Obviousness Analysis of U.S. Patent No. 11,120,271

A determination of obviousness under 35 U.S.C. § 103 requires a factual inquiry into the scope and content of the prior art, the differences between the prior art and the claims at issue, and the level of ordinary skill in the pertinent art. The central question is whether "the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art." The Supreme Court in KSR International Co. v. Teleflex Inc. emphasized a flexible approach, moving away from a rigid "teaching, suggestion, or motivation" (TSM) test. An invention can be deemed obvious if it represents a predictable variation of prior art elements, or if there was a known problem for which there was an obvious solution.

Based on the provided prior art, the claims of U.S. Patent No. 11,120,271 ("the '271 patent") appear vulnerable to an obviousness challenge. The core of the invention lies in using spatiotemporal data from a video feed to identify "semantic elements" and "semantic contexts" to generate and display context-aware augmentations, often in an interactive manner. The prior art, particularly when combined, teaches all the key elements of this process.

A person of ordinary skill in the art (POSA) at the time of the invention (with a priority date of February 28, 2014) would have been a computer scientist or engineer with experience in computer vision, machine learning, and interactive media. This individual would have been familiar with techniques for object recognition in video, data overlay, and user interface design for interactive applications.

Combination 1: Sato (U.S. Patent No. 9,736,547) in view of Tseng et al. (U.S. Patent No. 10,791,281)

Motivation to Combine:
Sato discloses a system for identifying objects in a video stream, such as players in a sports broadcast, and overlaying related information like statistics. This directly addresses the "augmentation" aspect of the '271 patent. However, Sato's system is primarily described as a passive display of information. A person of ordinary skill in the art, recognizing the growing trend of interactive user experiences in media consumption, would have been motivated to enhance Sato's system to allow for user engagement. Tseng et al. provides the clear solution by teaching an interactive augmented reality system for live events where users can interact with superimposed digital information. The motivation would be to improve the user experience of Sato's system by making the displayed information interactive, thereby increasing user engagement and providing a more dynamic and personalized viewing experience, a well-established goal in the field of digital media. This combination represents a predictable union of known technologies to achieve a desirable and expected result.

Mapping to Claim Elements (Illustrative Independent Claim):

• "receiving...video data...comprising video content and spatiotemporal data": Sato discloses receiving a video stream, which inherently contains spatiotemporal data (the position of players and objects over time). Tseng et al. also describe capturing and tracking object positions in a live event.
• "determining...one or more semantic elements": Sato teaches identifying objects in video frames, which corresponds to identifying "semantic elements" like players.
• "determining...one or more semantic contexts": Sato's system, by identifying a player, inherently determines a basic context (e.g., "player X is on the field"). The '271 patent's concept of "semantic context" appears to be a more granular level of analysis.
• "determining...an augmentation for each respective semantic element": Sato's system displays statistics for identified players, which is a form of augmentation.
• "generating...augmented video content": Sato's system superimposes information on the video, thereby generating augmented content.
• "enabling user interaction with the augmentation": This element, while not explicitly detailed in Sato, is the core teaching of Tseng et al. A POSA would find it obvious to apply the interactive features of Tseng et al. to the augmented data provided by Sato's system. For example, allowing a user to tap on a player (the "semantic element" identified by a Sato-like system) to bring up more detailed statistics or replays (the "interactive augmentation" taught by Tseng et al.).

Combination 2: Kondo (U.S. Patent No. 9,992,544) in view of Levin et al. (US 2018/0278972 A1)

Motivation to Combine:
Kondo describes a system that goes beyond simple object recognition to identify complex events and actions in a video, such as a "pick and roll" in basketball, based on patterns of movement (spatiotemporal data). This aligns with the '271 patent's focus on determining "semantic context" from spatiotemporal data. Kondo's system then provides information related to these recognized events. However, the augmentation described is general. Levin et al., on the other hand, teach a system for personalizing a media experience by tailoring the displayed information and augmentations based on a user's profile and past interactions.

A person of ordinary skill in the art would be motivated to combine these teachings to create a more sophisticated and engaging user experience. Kondo provides the powerful capability of deep, contextual understanding of the event (e.g., "this is a pick and roll play"). Levin et al. provides the mechanism to make the information presented about that event highly relevant to the individual user. The motivation would be to leverage the detailed event recognition of Kondo to provide the personalized augmentations described by Levin et al. For instance, if a user is a known fan of a particular player (a "user context" from Levin), and that player is involved in a "pick and roll" (a "semantic context" from Kondo), the system could display specialized statistics or highlights related to that player's performance in that specific type of play. This combination would be a logical step to enhance the value and engagement of the augmented video experience.

Mapping to Claim Elements (Illustrative Independent Claim):

• "receiving...video data...comprising video content and spatiotemporal data": Both Kondo and Levin et al. operate on video data from events, which includes spatiotemporal information.
• "determining...one or more semantic elements": Kondo explicitly teaches recognizing elements like players and the ball.
• "determining...one or more semantic contexts": Kondo's core contribution is the recognition of complex actions and plays (e.g., a "pick and roll"), which is a clear example of determining a "semantic context" from spatiotemporal data.
• "determining...an augmentation...based at least in part on...user context": This is directly taught by Levin et al., which describes tailoring augmentations based on user profiles and preferences. A POSA would find it obvious to use the user context from Levin et al. to select from the potential augmentations available for the specific game event identified by Kondo.
• "generating...augmented video content": Both references describe the display of information overlaid on the video. The combination would result in the generation of personalized augmented video content.

Conclusion

The claims of U.S. Patent No. 11,120,271, as understood from the provided information, appear to cover a system that integrates known concepts from the prior art in a predictable manner. The core ideas of identifying objects and events in video, overlaying contextual information, and making that information interactive and personalized were all present in the art before the patent's priority date. While the '271 patent may describe a particularly sophisticated and well-integrated system, the combination of references like Sato and Tseng et al., or Kondo and Levin et al., would have provided a person of ordinary skill in the art with both the components and the motivation to create the claimed invention. The novelty and non-obviousness of the patent likely reside in specific, detailed implementations of the spatiotemporal data analysis and the generation of "semantic contexts," which may not be fully captured in the high-level descriptions of the prior art. A more definitive conclusion would require a detailed comparison of the specific claim limitations with the disclosures in the prior art, along with an analysis of the arguments made during prosecution that persuaded the examiner of the patent's non-obviousness.

An analysis of the prosecution history and publicly available data for U.S. Patent No. 11,120,271 reveals the following information regarding its term, related applications, and family members.

Defensive Disclosure and Prior Art Generation Based on U.S. Patent No. 11,120,271

Subject Patent: U.S. Patent No. 11,120,271
Title: Data processing systems and methods for enhanced augmentation of interactive video content
Priority Date: February 28, 2014
Disclaimer: This document is a defensive publication intended to disclose concepts and technologies that build upon, extend, or modify the inventions described in U.S. Patent No. 11,120,271. The purpose is to place these concepts into the public domain to be considered prior art for any future patent applications.

Derivative Variations Based on Core Claims

The following derivative concepts are based on the core method of identifying semantic elements and their context from spatiotemporal video data to generate interactive augmentations.

---

1. Material & Component Substitution

Derivative 1.1: Neuromorphic Vision Sensor for Spatiotemporal Data Acquisition

• Enabling Description: The system is modified to replace conventional frame-based video cameras with event-based neuromorphic vision sensors (e.g., Dynamic Vision Sensors - DVS). Instead of processing a plurality of video frames, the system directly ingests an asynchronous stream of pixel-level brightness change events (spikes). The "spatiotemporal data" is now this event stream itself, not derived positional data. A Spiking Neural Network (SNN) is used for the "semantic element" identification, recognizing moving objects (players, balls) by their unique temporal signatures. The "semantic context" is determined by a Recurrent Neural Network (RNN) layer within the SNN that interprets sequences of spike events as specific actions (e.g., a "pick and roll"). Augmentations are triggered based on the SNN's classification output, and the rendering engine composites these augmentations onto a reconstructed video frame generated from the event stream for display. This substitution significantly reduces data bandwidth and processing latency, making it suitable for real-time edge computing applications.

      A --> F(Frame Reconstructor);
      F --> G[Video Frame];
      E & G --> H(Compositor);
      H --> I(Augmented Video Output);
  

Derivative 1.2: Volumetric Video (Voxel) Data as Spatiotemporal Input

• Enabling Description: The system is adapted to process volumetric video data (voxels) captured by a multi-camera array, rather than 2D video. The "spatiotemporal data" is the 4D (3D space + time) voxel dataset. Semantic element identification is performed by a 3D Convolutional Neural Network (3D-CNN) that directly analyzes the voxel data to segment and classify objects (players, equipment) in three-dimensional space. "Semantic context" is derived from analyzing the volumetric change and interaction between these 3D object models over time. Augmentations are rendered as 3D objects or data visualizations placed within the 3D scene, which can be viewed from any virtual camera angle selected by the user. This enables a fully immersive, "free-viewpoint" augmented reality sports experience.

Derivative 1.3: Graphene-based Wearable Sensors for Player Spatiotemporal Data

• Enabling Description: The spatiotemporal data is generated not from video but from a network of graphene-based strain and inertial measurement unit (IMU) sensors integrated into player jerseys and equipment (e.g., ball, shoes). These sensors provide high-frequency, low-latency data on player limb orientation, velocity, acceleration, and ball impact forces. The "semantic elements" (players, ball) are pre-identified by their sensor IDs. The "semantic context" is determined by a machine learning model (e.g., a Long Short-Term Memory network, LSTM) trained to recognize specific athletic movements and plays (e.g., shooting form, tackle type, swing mechanics) from the multi-channel sensor time-series data. This system decouples the augmentation from the broadcast video feed, allowing personalized, biomechanical augmentations to be overlaid on any video source or even a virtual representation of the game.

2. Operational Parameter Expansion

Derivative 2.1: Microfluidic Analysis Augmentation

• Enabling Description: The system is applied at a microscopic scale to analyze video feeds from high-speed cameras observing microfluidic "lab-on-a-chip" devices. The "semantic elements" are individual cells, droplets, or micro-particles flowing through channels. The "spatiotemporal data" is derived from high-frequency particle tracking velocimetry (PTV) algorithms. The "semantic context" involves identifying cellular behaviors like mitosis, apoptosis, or chemotaxis, or detecting anomalies in fluid flow patterns. Augmentations include overlaying color-coded velocity vectors, highlighting specific cells that exhibit target behaviors, and plotting real-time graphs of particle concentrations. User interaction allows a researcher to select a single cell and track its complete path and state changes over time.

Derivative 2.2: Hyperspectral Satellite Imagery Analysis

• Enabling Description: The system is scaled to operate on time-series hyperspectral satellite imagery for agricultural or environmental monitoring. A "video frame" is a single satellite image capture, and a sequence of captures over time constitutes the video. "Semantic elements" are distinct land parcels, crop types, or water bodies identified through spectral signature analysis. "Spatiotemporal data" includes the location, size, and spectral changes of these elements over days, weeks, or months. "Semantic context" is determined by analyzing these changes to detect events like crop stress, illegal deforestation, or algal blooms. Augmentations include overlaying color-coded health indices (e.g., NDVI), drought warnings, or predicted yield data directly onto the satellite imagery map.

3. Cross-Domain Application

Derivative 3.1: Aerospace - Automated Air Traffic Control

• Enabling Description: The system is applied to real-time radar and ADS-B data feeds, visualized on a 2D or 3D air traffic control map. The "video content" is the real-time map display. "Semantic elements" are individual aircraft, identified by their transponder codes. The "spatiotemporal data" is their 4D trajectory (latitude, longitude, altitude, time). The system's machine learning model determines "semantic context" by predicting potential conflicts, such as loss of separation or runway incursion risks, based on flight vectors and known airport procedures. Augmentations include highlighting conflicting aircraft in red, drawing projected flight paths with color-coded risk levels, and automatically generating resolution advisories (e.g., "Climb FL350") as interactive overlays for the controller to approve or reject.

Derivative 3.2: AgTech - Autonomous Pest and Disease Detection

• Enabling Description: The system is deployed on an agricultural drone equipped with multispectral cameras. The "video content" is the live feed from the drone's cameras as it flies over a field. "Semantic elements" are individual plants or sections of a crop row. "Spatiotemporal data" is the GPS-tagged location of each frame and the visual data within it. The system uses a trained computer vision model to determine the "semantic context" of each plant, such as "healthy," "nutrient deficient," "insect-infested," or "diseased." Augmentations are overlaid in real-time on the operator's display, color-coding areas of the field based on health status. User interaction allows the operator to tap on a highlighted area to view detailed multispectral readings, zoom in on the specific pest identified, and dispatch a targeted spraying drone to that precise GPS coordinate.

Derivative 3.3: Retail - In-Store Shopper Behavior Analysis

• Enabling Description: In a retail environment, the "video content" is from overhead cameras. "Semantic elements" are individual shoppers, identified and tracked anonymously. The "spatiotemporal data" consists of their movement paths, dwell times in different aisles, and interactions with products. The "semantic context" is the classification of shopping behavior, such as "browsing," "comparing products," "seeking assistance," or "abandoning cart." Augmentations are provided on a store manager's dashboard, showing a real-time heatmap of store activity, highlighting shoppers who have been waiting for assistance for over a threshold time, or flagging unusual movement patterns that might indicate theft. An alert could be triggered to a store associate's mobile device, showing a video clip of the event and the shopper's location.

4. Integration with Emerging Tech

Derivative 4.1: AI-Driven Predictive Augmentation

• Enabling Description: The system is integrated with a predictive AI model trained on vast datasets of historical games. The "semantic context" determination is enhanced to be predictive. Based on the current spatiotemporal data (player positions, velocities), the AI model calculates the probabilities of various near-future events (e.g., "75% chance of a 3-point shot attempt," "40% chance of a turnover"). The system then "pre-fetches" and renders relevant augmentations before the event occurs. For example, as a player dribbles towards the three-point line, their season 3-point percentage is pre-emptively displayed. If the user interacts with this predictive augmentation, it could trigger a display of probability-weighted shot charts showing the most likely outcomes.

Derivative 4.2: IoT Sensor Fusion for Enhanced Context

• Enabling Description: The system's "spatiotemporal data" is augmented with data from a network of IoT sensors. In a sports context, this includes biometric sensors on players (heart rate, fatigue level), environmental sensors in the stadium (temperature, humidity), and even crowd noise level sensors. The "semantic context" determination now fuses video-derived data with this IoT data. For example, the system can identify a "fatigued player" context when their in-game speed (from video tracking) drops while their heart rate (from IoT sensor) remains high. The resulting augmentation could be a visual indicator over the player, alerting a coach to a potential substitution need, or providing commentators with a data-driven talking point.

      E --> F[Augmented Video Output];
  

Derivative 4.3: Blockchain for Verifiable Augmentations and Micro-transactions

• Enabling Description: Each spatiotemporal event and its associated semantic context (e.g., "Player A scored a 3-point shot at game time 10:32") is hashed and recorded as a transaction on a distributed ledger (blockchain). The augmentations displayed to users, especially those related to gambling or official statistics, include a cryptographic signature that can be verified against the blockchain record, ensuring data integrity and provenance. Furthermore, user interaction with certain augmentations can trigger micro-transactions. For example, a user clicking a "Collect This Highlight" button on an augmented video clip could trigger a smart contract to mint a Non-Fungible Token (NFT) of that specific play, transferring ownership to the user's digital wallet.

5. The "Inverse" or Failure Mode

Derivative 5.1: Graceful Degradation Mode for Low-Bandwidth Environments

• Enabling Description: The system incorporates a "low-power" or "graceful degradation" mode that activates when the client device detects poor network bandwidth or limited processing capability. In this mode, the system prioritizes the core video stream. The "spatiotemporal data" received is down-sampled, and the "semantic element" detection is limited to only primary objects (e.g., just the ball carrier, not all players). "Semantic context" analysis is simplified to basic events (e.g., "shot" vs. "pass") instead of complex plays. Augmentations are switched from processor-intensive 3D graphics to lightweight, static text or simple icons. User interaction is limited to toggling these simple data points on/off, rather than triggering new video streams or complex overlays, ensuring the core viewing experience remains fluid.

Derivative 5.2: Privacy-Preserving Augmentation via Anonymization

• Enabling Description: This "inverse" application uses the same core technology to enhance privacy. The system processes video from a public space (e.g., a city square). The "semantic element" identification algorithm detects all human figures. However, instead of augmenting them with identifying information, the system applies an obfuscation augmentation. It generates a "privacy bounding box" for each person and applies a real-time blur or pixelation filter only within that box. The "spatiotemporal data" is used to track the bounding boxes accurately as people move. The "semantic context" engine can be configured to selectively de-anonymize authorized personnel (e.g., security guards) based on a uniform or other identifier, while keeping all other individuals anonymized in the security feed.

Combination Prior Art Scenarios

Combination 1: Integration with WebRTC and TensorFlow.js for Browser-Based Real-Time Augmentation

• Enabling Description: The methods of patent 11,120,271 are implemented entirely within a web browser using open standards. A live video stream of a sporting event is delivered to the client's browser via WebRTC, a standard protocol for real-time peer-to-peer communication. On the client side, a lightweight computer vision model for object tracking, built using the TensorFlow.js library, runs directly in the browser. This model processes the incoming video frames to extract basic spatiotemporal data (x, y coordinates of players). This data, along with a timestamp, is sent to a remote server which performs the more intensive "semantic context" analysis. The server sends back lightweight augmentation data (e.g., JSON objects with text and display coordinates). The client-side JavaScript then renders these augmentations as HTML5 Canvas or SVG overlays on top of the <video> element. This combination makes the interactive video experience accessible on any modern web browser without plugins, leveraging open-source ML libraries for client-side processing.

      Analytics_Server->>Browser: Returns augmentation data (JSON)
      Browser->>Browser: Renders HTML5 Canvas overlay on video
  

Combination 2: Integration with MPEG-DASH and Timed Metadata Tracks (EMSG)

• Enabling Description: The system's output is packaged for standards-compliant adaptive bitrate streaming. The "spatiotemporal data" and "semantic context" information (e.g., play type, player ID, coordinates) is encoded into a timed metadata track, specifically using the "Events Message" (emsg) box format within the MPEG-DASH standard. The video server generates the DASH manifest (MPD) which lists the available video, audio, and the new metadata tracks. A standard-compliant DASH player on a client device plays the video and simultaneously parses the emsg boxes as they arrive. The player's application logic uses the data from these timed events to trigger the rendering of augmentations, synchronizing them precisely with the video frames. This allows the augmented experience to be delivered through standard Content Delivery Networks (CDNs) and played on a wide range of devices that support MPEG-DASH, without requiring a custom video player.

          H & I --> J(Synchronized Augmented Display);
      end
  

Combination 3: Integration with ROS (Robot Operating System) for Autonomous Drone Cinematography

• Enabling Description: The system is integrated into an autonomous drone running the Robot Operating System (ROS), an open-source framework for robot software development. The drone's camera provides the "video content". Onboard computer vision nodes running within ROS perform real-time object detection and tracking to generate "spatiotemporal data" for players on a field. A "semantic context" node analyzes this data to identify key moments in a game (e.g., a breakaway, a goal, a key defensive play). This context is used to trigger an "augmentation," which in this case is not a visual overlay, but a command to the drone's flight control system. For example, upon detecting a "fast break" (semantic context), the system commands the drone to automatically switch to a more cinematic "chase" camera angle, smoothly following the lead player. This combines the patent's event-detection capabilities with open-source robotics control software to create an automated, intelligent sports cinematographer.
