US 9055255

US Patent 9055255, titled "Live television application on top of live feed," was filed on August 16, 2013, and issued on June 9, 2015. The original assignee was Flextronics AP LLC, and the current assignee is Multimedia Technologies Pte Ltd. The inventors are Gregory Burdzinski, Tong Chen, Eduardo Diego Torres Milano, Todd Lee, and John S. Visosky.

Abstract:
The patent describes an intelligent television (TV) that runs a live TV application to control interactive user functions. While live TV broadcast content is displayed on a first portion of the screen, the TV receives input for the live TV application. In response to this input, a live TV application feature is determined and presented on a second portion of the display, which overlaps at least part of the live TV broadcast content. This feature allows users to interact with the TV's functions through the application, even while watching live television.

Independent Claims Overview:

• Claim 1 (Method): This claim outlines a method for an intelligent TV. It involves running a live TV application that manages interactive functions. Simultaneously, live broadcast TV is shown on one part of the screen. When the TV receives input for the live TV application, it identifies a specific application feature to display. This feature, which controls the interactive functions, is then shown on another part of the screen, overlapping some of the live TV broadcast.
• Claim 9 (Non-transitory Computer Readable Medium): This claim covers a tangible, non-transitory computer-readable medium (e.g., a hard drive or flash memory) that stores instructions. When a processor executes these instructions, they cause the intelligent TV to perform the method described in Claim 1.
• Claim 17 (System): This claim describes a system that includes an intelligent TV with a display and a tuner (for receiving broadcast signals), an input device, and memory. It also includes a microprocessor configured to perform the actions detailed in Claim 1: running a live TV application, displaying live TV content, receiving application input, determining an application feature, and presenting that feature on the screen, overlapping the live broadcast.

The following is an analysis of prior art cited in US Patent 9,055,255.

Claims of US9055255

For context, the independent claims of US9055255 describe:

• Claim 1 (Method): Running a live TV application on an intelligent TV to control interactive user functions, presenting live TV broadcast content to a first portion of the display, receiving a live TV application input, determining a live TV application feature to present, and presenting the live TV application feature to a second portion of the display, where the second portion overlaps at least a portion of the live TV broadcast content.
• Claim 9 (Computer Readable Medium): A tangible, non-transitory computer readable medium with instructions to perform the method of Claim 1.
• Claim 10 (System): An intelligent TV with a display and tuner, an input device, memory, and a microprocessor configured to perform the method of Claim 1.

The core innovative elements revolve around simultaneously displaying live TV broadcast content and an interactive live TV application feature, where the application feature overlaps the broadcast content, and user input controls interactive functions via this application feature.

Most Relevant Prior Art for US9055255

Identifying the "most relevant" prior art often involves a detailed claim-by-claim analysis. However, based on the abstract and general nature of US9055255 (presenting an interactive application overlaying live TV), prior art that discloses displaying additional information or interactive elements on top of a television program would be highly relevant. Many of the cited patents by Kameyama et al. and Yuen et al. fall into this category, focusing on interactive television systems and user interfaces.

Here's an analysis of a selection of cited patents, focusing on those most likely to anticipate the core elements of US9055255:

U.S. Patent Documents

1. US 5,373,312 A

• Full Citation: US 5,373,312 A to Yuen et al.
• Publication/Filing Date: Publication: December 13, 1994
• Brief Description: This patent describes a system for providing an interactive television program guide. It allows users to browse program listings and select programs for viewing, potentially displaying the guide as an overlay or picture-in-picture with the current television program.
• Potential Anticipation (35 U.S.C. § 102): This patent potentially anticipates elements of claims 1, 9, and 10 related to displaying an interactive user interface (program guide) simultaneously with broadcast content and receiving user input to interact with it. Specifically, the concept of an "application" (the program guide) controlling "interactive user functions" (program selection) and being "presented ... to a second portion of the display, wherein the second portion of the display overlaps at least a portion of the presented live TV broadcast content" could be found here.

2. US 6,654,964 B1

• Full Citation: US 6,654,964 B1 to Ozer et al.
• Publication/Filing Date: Publication: November 25, 2003
• Brief Description: This patent describes an interactive multimedia system that allows a user to access services such as video-on-demand, interactive television programming, and internet services. It includes a user interface for navigating these options.
• Potential Anticipation (35 U.S.C. § 102): This patent potentially anticipates claims 1, 9, and 10 by disclosing an interactive system on a television that offers various services (applications) and responds to user input. If its user interface can overlay or be presented alongside live broadcast content, it could anticipate the simultaneous display and interactive control aspects.

3. US 6,950,984 B1

• Full Citation: US 6,950,984 B1 to Kameyama et al.
• Publication/Filing Date: Publication: September 27, 2005
• Brief Description: This patent details an interactive television system providing on-screen displays (OSDs) for various functions, such as electronic program guides, video-on-demand, and interactive advertisements. The system uses a client device (e.g., set-top box) to generate these OSDs and allow user interaction with them while watching television.
• Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant as it explicitly addresses interactive television with on-screen displays. The "on-screen displays" could be considered "live TV application features" that "overlap at least a portion of the presented live TV broadcast content." The system's ability to receive user input and control functions via these OSDs directly aligns with claims 1, 9, and 10 of US9055255.

4. US 7,412,713 B2

• Full Citation: US 7,412,713 B2 to Ozer et al.
• Publication/Filing Date: Publication: August 12, 2008
• Brief Description: This patent describes a system and method for an interactive program guide, including displaying program information in various formats and allowing user interaction for content selection and control. It further addresses the presentation of such guides in conjunction with a main video program.
• Potential Anticipation (35 U.S.C. § 102): Similar to US 5,373,312 and US 6,950,984, this patent directly deals with interactive program guides that would overlay or appear alongside live TV. The "interactive program guide" acts as a "live TV application" enabling "interactive user functions" (e.g., channel changing, program selection) while "overlapping at least a portion of the presented live TV broadcast content," thus potentially anticipating claims 1, 9, and 10.

5. US 2003/0188310 A1

• Full Citation: US 2003/0188310 A1 to Ozer et al.
• Publication/Filing Date: Publication: October 2, 2003
• Brief Description: This application describes an interactive television system that provides on-screen graphical user interfaces (GUIs) for interacting with various services, including content selection and other TV functions. The GUI can be superimposed on or presented with the broadcast video.
• Potential Anticipation (35 U.S.C. § 102): This pre-grant publication clearly teaches displaying interactive on-screen GUIs over broadcast content to control television functions. This directly corresponds to the elements of claims 1, 9, and 10, particularly the "live TV application feature" overlapping the broadcast content and controlling "interactive user functions" via input.

Many of the other patent application publications, particularly those by Kameyama et al. and Yuen et al. published in 2007 and 2008, also describe various aspects of interactive television systems and user interfaces that present on-screen elements (such as menus, guides, or informational overlays) simultaneously with live TV content, enabling user interaction. Without a detailed review of each, it's difficult to pinpoint specific distinctions, but their general theme of interactive TV with on-screen displays suggests broad relevance to US9055255's claims.

The term "Intelligent TV" in US9055255 is defined as a TV providing "one or more intuitive user interfaces and interactions based on a unique application platform and architecture" and integrating "Internet connectivity with parallel application functionality." Many of the prior art references, especially those from the early 2000s, describe systems that would today be considered precursors or early forms of "Smart TVs" or "Intelligent TVs" due to their interactive features and on-screen displays. The novelty of US9055255 would likely rest on the specific nature of the "live TV application" and its integration or "seamless" operation, as opposed to merely displaying an overlay. However, the basic concept of an interactive overlay on live TV is well-covered by the cited prior art.

The provided patent text for US9055255 includes "Prior art keywords" and a "Prior art date," but does not list specific prior art references (e.g., patent numbers or publications) within the provided content. To conduct a thorough obviousness analysis under 35 U.S.C. § 103, specific prior art documents are required.

However, recognizing that the user prompt includes the URL for the patent on Google Patents (https://patents.google.com/patent/US9055255/en) and instructs to "prefer the search results" if they contradict the training data, I have accessed the live Google Patents page to identify the cited prior art.

Obviousness Analysis under 35 U.S.C. § 103

The independent claims of US9055255 (e.g., Claim 1, which defines a method) describe running a live TV application on an intelligent TV, presenting live TV broadcast content, receiving input, determining a feature to present, and then presenting that feature in a second portion of the display that overlaps the live TV broadcast content.

Claim 1 of US9055255 states:
A method comprising:
a. running, via a processor associated with an intelligent television (TV), a live TV application, wherein the live TV application is configured to control one or more interactive user functions of the intelligent TV;
b. presenting, simultaneously via a display of the intelligent TV, live TV broadcast content, wherein the live TV broadcast content is presented to a first portion of the display;
c. receiving a live TV application input at the intelligent TV;
d. determining, by the processor and in response to receiving the live TV application input, a live TV application feature to present via the display, wherein the one or more interactive user functions of the intelligent TV are controlled via the live TV application feature; and
e. presenting, via the display, the live TV application feature to a second portion of the display, wherein the second portion of the display overlaps at least a portion of the presented live TV broadcast content.

A combination of prior art references would render the claims of US9055255 obvious to a person having ordinary skill in the art (PHOSITA). Specifically, the combination of US20080034374A1 and US20120159496A1, potentially supplemented by US20120204221A1 and general knowledge of smart TV technology, appears to cover all essential elements of Claim 1.

Combination of Prior Art References:

1. US20080034374A1 (Interactive television display with a transparent region for presenting additional content to a user): This reference teaches an "interactive television display" capable of presenting "additional content" via a "transparent region" that overlays the primary content. This directly addresses the following elements of Claim 1:

   • "presenting, simultaneously via a display of the intelligent TV, live TV broadcast content, wherein the live TV broadcast content is presented to a first portion of the display": An interactive television display inherently shows primary TV content.
   • "presenting, via the display, the live TV application feature to a second portion of the display, wherein the second portion of the display overlaps at least a portion of the presented live TV broadcast content": This is explicitly taught by the "transparent region for presenting additional content to a user," where the "additional content" would constitute the "live TV application feature." The patent US9055255 itself defines a "panel" as being "translucent whereby the panel obscures but does not mask the underlying content being displayed in the display," which aligns with the concept of a transparent region.
   • "receiving a live TV application input" / "interactive user functions": The term "interactive television display" implies the capability to receive user input and control interactive functions.

2. US20120159496A1 (Apparatus and method for providing an application based television guide): This reference teaches "providing an application based television guide," which directly corresponds to:

   • "running, via a processor associated with an intelligent television (TV), a live TV application, wherein the live TV application is configured to control one or more interactive user functions of the intelligent TV": An application-based television guide is a prime example of a "live TV application" as it relates to live broadcast content. Such a guide is inherently configured to control interactive user functions, such as displaying program information, changing channels, or setting reminders. The "Intelligent TV" (or Smart TV) concept, as defined in US9055255, explicitly involves running applications and providing intuitive user interfaces for navigating content.
   • "determining, by the processor and in response to receiving the live TV application input, a live TV application feature to present via the display": An application-based TV guide necessarily determines what information (e.g., program details, schedule grids) to present based on user input (e.g., selecting a channel or time slot) and controls related interactive functions.

3. US20120204221A1 (Context-sensitive remote control user interface): This reference further reinforces the "receiving a live TV application input" element by detailing methods for user interaction with a television system, specifically through a "context-sensitive remote control user interface." This device would be a natural choice for providing input to the "live TV application" (e.g., the TV guide).

Motivation to Combine:

A PHOSITA in August 2012 would have been strongly motivated to combine the teachings of US20080034374A1 and US20120159496A1 for several reasons:

1. Advancements in Television Technology and User Experience: The concept of "Smart TVs" and "Intelligent TVs" was rapidly evolving, aiming to integrate internet and application functionalities with traditional broadcast television. The US9055255 patent itself highlights the goal of providing "seamless and intuitive user interfaces for navigating and/or executing the various features of the Smart TV". Overlaying interactive applications, like a TV guide, directly onto the live broadcast stream would enhance the user experience by allowing viewers to access information and controls without fully interrupting their primary viewing. This is a natural progression of user interface design.
2. Common GUI Practices: Displaying supplemental content, such as menus or information banners, as overlays (e.g., translucent panels) on top of primary video content was a well-established graphical user interface (GUI) technique by 2012. This is evidenced by various classifications cited in US9055255, such as H04N5/445 ("Receiver circuitry... for displaying additional information"), H04N5/45 ("Picture in picture"), and G06F2203/04804 ("Transparency, e.g. transparent or translucent windows"). Applying an "application based television guide" (US20120159496A1) to such an overlay display mechanism (US20080034374A1) would be a logical and desirable improvement.
3. Efficiency and Contextual Information: A TV guide is frequently accessed while watching live television. Presenting it in an overlapping, interactive panel, as taught by US20080034374A1, would allow users to quickly glance at schedules or get program details without having to navigate to a separate, full-screen menu, thus maintaining context and reducing cognitive load. This directly addresses the desire for "intuitive user interaction capability" of "Intelligent TVs".
4. Integration of Input Mechanisms: The integration of input devices, such as the remote control detailed in US20120204221A1, with interactive displays and applications was also a well-known area of development. A PHOSITA would readily understand how to adapt such an input mechanism to control an application-based TV guide displayed as an overlay.

In summary, a PHOSITA, aiming to improve the interactive capabilities and user experience of a television system, would have found it obvious to combine an "application based television guide" (US20120159496A1) with an "interactive television display with a transparent region for presenting additional content to a user" (US20080034374A1). This combination, further supported by the knowledge of remote control interfaces (US20120204374A1), directly anticipates the method claimed in US9055255.

US Patent 9055255, titled "Live television application on top of live feed," has a complex family history and its projected expiration date can be influenced by several factors.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate patent applicants for certain delays caused by the USPTO during the patent prosecution process. These delays include failing to issue an office action or notice of allowance within 14 months of filing, failing to act within four months of an applicant's response, or failing to issue a patent within three years of the actual filing date of the application. The USPTO automatically calculates and transmits a notice of determination for PTA on or before the patent's issuance date. The applicant has a window of two months (with a possible five-month extension) to request reconsideration of the PTA calculation.

Specific PTA details for US9055255 are not available within the provided search snippets. To determine the exact PTA, the patent's file wrapper in USPTO Patent Center would need to be consulted.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available under the Hatch-Waxman Act for patents claiming products that require regulatory approval from agencies like the FDA before commercial marketing, such as human and veterinary pharmaceuticals, food additives, color additives, and medical devices. The purpose of PTE is to restore some of the patent term lost during this regulatory review period.

Given that US9055255 relates to an "Intelligent Television (TV)" and "live TV application," it is highly unlikely to be eligible for PTE, as it does not appear to cover products requiring premarket government approval under 35 U.S.C. § 156.

The patent family for US9055255 consists of 101 related applications that share a priority claim. These patents and applications are derived from the earliest priority date, which is June 14, 2012.

Projected Expiration Date

The filing date for US9055255 is August 16, 2013, and its earliest priority date is August 17, 2012. Generally, a U.S. patent's term is 20 years from its earliest non-provisional filing date. The Google Patents page for US9055255 currently indicates a "Projected expiration" date of "2033-08-16". The "IHatePatentTrolls" database indicates a "Projected expiration: Jun 14, 2032 active". This earlier date on IHatePatentTrolls is based on 20 years past the earliest priority date (June 14, 2012), and explicitly states it "does not reflect terminal disclaimers, patent term adjustment, or extension."

Considering the filing date of August 16, 2013, a base patent term of 20 years would lead to an expiration date of August 16, 2033. This aligns with the "Anticipated expiration" date provided in the Google Patents information for US9055255.

It's important to note that this projected date does not account for any Patent Term Adjustment (PTA) that may have been granted due to USPTO delays, or any potential terminal disclaimers. To get the definitive expiration date, including any PTA, the official documentation from the USPTO, typically found in the patent's file wrapper, would need to be reviewed.

Derivative Variations

1. Material & Component Substitution

1.1. Derivative: Quantum Dot Organic Light-Emitting Diode (QD-OLED) Display with Haptic Feedback Touch Input

Enabling Description:
An intelligent TV system (analogous to the system of claim 17) utilizes a QD-OLED display panel for presenting both live TV broadcast content and live TV application features. The QD-OLED technology provides superior color gamut, black levels, and viewing angles compared to traditional LCDs or even standard OLEDs. The display integrates an advanced multi-touch capacitive sensor array directly beneath the QD-OLED emission layers, allowing for direct user interaction with on-screen application features. This touch layer is augmented with localized haptic actuators (e.g., piezoelectric haptic drivers or linear resonant actuators) capable of providing tactile feedback correlated with UI element interaction, such as button presses, scrolling, or selection confirmation. The system's processor (as in claim 17) interprets touch gestures and haptic feedback profiles from a dedicated haptic feedback controller chip to render dynamic tactile responses. Communication between the display panel, haptic drivers, and main processor is facilitated via a high-speed, low-latency interface (e.g., MIPI DSI or eDP with custom haptic data lanes) to ensure synchronized visual and tactile feedback. The live TV application (as in claim 1) would dynamically adjust overlay transparency and haptic intensity based on user preferences or content type.

1.2. Derivative: Micro-LED Display with Gaze Tracking and Brain-Computer Interface (BCI) Input

Enabling Description:
An intelligent TV system is implemented with a large-format Micro-LED display, offering extreme brightness, contrast, and modular scalability suitable for high-resolution public or private viewing. User input (as in claim 1) for the live TV application is primarily achieved through a combination of integrated gaze-tracking sensors (e.g., infrared eye-tracking cameras operating at 240Hz or higher) and a non-invasive BCI headband (e.g., EEG-based with dry electrodes). The gaze-tracking system determines the user's focal point on the display, implicitly selecting or highlighting interactive elements of the live TV application feature. Explicit commands (e.g., "select," "scroll," "confirm") are triggered by specific neural patterns detected by the BCI, which are learned and classified by a dedicated BCI processing unit within the intelligent TV's processor (as in claim 17). The live TV application (as in claim 1) presents application features with dynamic visual cues that respond to gaze (e.g., highlighting, subtle animations) and executes commands based on recognized BCI signals, ensuring a hands-free interactive experience.

1.3. Derivative: Ferroelectric Liquid Crystal (FLC) on Flexible Substrate with Integrated Strain Gauge Input

Enabling Description:
An intelligent TV system (as in claim 17) employs a flexible Ferroelectric Liquid Crystal (FLC) display panel, mounted on a compliant substrate (e.g., polyimide or PEN), allowing for curved or rollable TV form factors. FLC technology enables fast switching times and wide viewing angles. The interactive input mechanism (as in claim 1) is based on an array of integrated strain gauges (e.g., piezoresistive or fiber optic) embedded directly into the flexible display's substrate or frame. When a user applies pressure or slight deformation to the flexible display surface, the strain gauges detect the localized deformation. A dedicated microcontroller processes the differential strain signals to triangulate the touch location and pressure intensity. The live TV application (as in claim 1) presents interactive features (e.g., soft buttons, sliders) on the flexible display, and user input is registered by pressing or bending the screen at the corresponding feature's location. The flexibility allows for dynamic adjustment of the screen's curvature based on viewing distance or application context.

4. Integration with Emerging Tech

4.1. Derivative: AI-Driven Contextual Live TV Application Optimization

Enabling Description:
An intelligent TV system (as in claim 17) integrates an AI-driven optimization module into its processor. This module constantly analyzes user viewing habits, historical interactions with the live TV application (as in claim 1), and real-time content metadata (e.g., genre, actors, current events related to the broadcast). When a user provides a live TV application input, the AI module, leveraging machine learning algorithms (e.g., reinforcement learning, neural networks trained on user behavior data), determines the most relevant "live TV application feature" to present, and its optimal presentation parameters (e.g., size, transparency, location of the overlapping second portion). For instance, if the user frequently searches for sports statistics while watching a game, the AI might proactively suggest a sports statistics overlay rather than a general program guide. The AI continuously refines its recommendation and presentation strategies based on implicit (e.g., gaze duration, interaction frequency) and explicit (e.g., user ratings) feedback.

4.2. Derivative: IoT Sensor-Integrated Live TV Application for Smart Home Control

Enabling Description:
An intelligent TV system (as in claim 17) is seamlessly integrated with a local IoT smart home network. The TV's processor (as in claim 17) receives real-time data from various IoT sensors (e.g., motion detectors, smart thermostats, door/window sensors, smart lighting) distributed throughout the home. The "live TV application" (as in claim 1) acts as a centralized smart home control dashboard. It presents interactive "live TV application features" such as room-specific climate controls, lighting adjustments, security alerts, and energy consumption statistics as overlays on the live broadcast content. For example, if a motion sensor detects activity at the front door, a discreet alert panel might appear. Users interact with these features using the TV's remote control or embedded voice assistant, controlling smart home devices directly from the TV interface without interrupting their viewing experience.

4.3. Derivative: Blockchain-Secured Content Rights and Interactive Feature Licensing

Enabling Description:
An intelligent TV system (as in claim 17) implements a blockchain-based module within its secure element processor. This module manages content rights verification for premium live TV broadcast content (as in claim 1) and licenses interactive application features. Each "live TV application feature" (e.g., enhanced sports statistics, interactive voting, exclusive behind-the-scenes content overlays) is associated with a unique non-fungible token (NFT) or a smart contract on a distributed ledger (e.g., Ethereum or a private consortium blockchain). When a user provides input requesting a feature, the system's processor verifies the user's ownership or valid license for the corresponding NFT/smart contract via the blockchain module before presenting the feature. This ensures secure, immutable, and auditable access control for interactive content and prevents unauthorized use. Payment for specific features could also be processed instantly via crypto wallets linked to the user's TV profile, with transactions recorded on the blockchain.

5. The "Inverse" or Failure Mode

5.1. Derivative: Graceful Degradation to Basic Broadcast in Low-Power Mode

Enabling Description:
An intelligent TV system (as in claim 17) is equipped with a power management unit and a low-power mode controller. When the system detects a low power condition (e.g., battery power below a threshold, extended power grid instability, or user-selected low-power mode), the "live TV application" (as in claim 1) gracefully degrades its functionality. All non-essential interactive user functions are temporarily suspended. The "live TV application feature" (as in claim 1) presented to the second portion of the display reduces its visual complexity (e.g., static, monochrome text only), its refresh rate, and its processing load. The overlay may shrink to a minimal informational banner or disappear entirely, leaving only the "live TV broadcast content" presented to the first portion of the display. This ensures that the primary function of displaying live TV is maintained for as long as possible, consuming minimal power, while interactivity is reduced or disabled to conserve resources. The system processor (as in claim 17) prioritizes core video decoding and display functions.

5.2. Derivative: Emergency Broadcast Overlay with Fail-Safe Redundancy

Enabling Description:
An intelligent TV system (as in claim 17), particularly for public safety applications, incorporates a dual-redundant hardware and software architecture. In a critical emergency scenario (e.g., natural disaster, civil alert, detected system fault in the primary application), the "live TV application" (as in claim 1) is immediately superseded by a high-priority "emergency broadcast application." This application's feature (e.g., a flashing, full-screen emergency alert banner with critical instructions) is presented to the second portion of the display, overlapping and potentially fully obscuring the "live TV broadcast content." This emergency overlay is driven by the redundant, fail-safe processor, ensuring that even if the primary system or application fails, critical alerts are always displayed. Input mechanisms for the emergency application are simplified (e.g., a single "acknowledge" button) and bypass standard application logic, directly engaging the redundant system. The display has a dedicated, non-volatile memory for storing emergency templates.

5.3. Derivative: User-Configurable Parental Control & Limited Functionality Mode

Enabling Description:
An intelligent TV system (as in claim 17) includes a robust user profile and parental control module. The "live TV application" (as in claim 1) dynamically adjusts its available "interactive user functions" and "live TV application features" based on the currently active user profile. For example, in a "Child Profile," the application feature presented to the second, overlapping portion of the display may only include pre-approved content recommendations or educational games, while restricting access to system settings or mature content. The input device (as in claim 17) may also have limited functionality, with certain buttons or gestures disabled. An "Elderly Mode" might increase text size, simplify navigation, and only present a limited set of high-contrast, easily visible interactive features. The system's processor (as in claim 17) applies these profile-specific policies at runtime, filtering application features and modifying user interface responsiveness. Access to change profiles or override restrictions requires a secure PIN or biometric authentication (e.g., facial recognition).

Combination Prior Art Scenarios

Here are at least three scenarios combining US Patent 9055255 with existing open-source standards to demonstrate prior art.

1. US9055255 + HbbTV (Hybrid Broadcast Broadband TV) Standard

Enabling Description:
A system combining the principles of US9055255 with the open-source HbbTV standard (e.g., as defined by ETSI TS 102 796) would involve an intelligent TV running a live TV application that is, in fact, an HbbTV application. HbbTV allows broadcasters to deliver interactive content and applications (HTML5/CSS/JavaScript-based) over broadband alongside traditional broadcast signals. The "live TV application" of US9055255 would be an HbbTV application that retrieves additional data (e.g., sports statistics, voting polls, social media feeds) from a broadband connection. When a user provides input (e.g., via a remote control or smart TV app), this HbbTV application determines a feature (e.g., a "red button" interactive service) and presents it as an overlay (the "second portion of the display overlapping live TV broadcast content") on the live TV program. The HbbTV standard explicitly defines how such interactive applications are signaled, synchronized, and rendered as overlays on broadcast streams, directly anticipating the claims of US9055255 in a standardized, open manner.

    participant C as CDN (HbbTV Content)
    participant T as Intelligent TV (Tuner, Processor, Display)

    T->>C: HbbTV App requests feature data
    C->>T: Sends interactive data (e.g., poll, stats)
    T->>T: HbbTV App renders feature as Overlay (Second Portion)
    T->>T: Display Live TV + HbbTV Overlay Simultaneously
    U->>T: User Interacts with Overlay
    T->>C: HbbTV App sends user interaction data

2. US9055255 + DVB-GEM (Globally Executable MHP) Standard

Enabling Description:
A system combining the principles of US9055255 with the open-source DVB-GEM standard (ETSI EN 301 790, which defines the DVB-MHP application environment as Globally Executable MHP) would utilize MHP (Multimedia Home Platform) applications as the "live TV application" of US9055255. DVB-GEM enables interactive digital television services by specifying a Java-based middleware for set-top boxes and integrated TVs. A DVB-GEM application could be broadcast as part of the MPEG transport stream or delivered via IP. This application would be configured to control various interactive user functions. When the intelligent TV receives input (e.g., from a remote control), the DVB-GEM application determines a feature (e.g., an interactive quiz, supplementary information about the current program) and presents it as a graphical overlay (the "second portion of the display overlapping live TV broadcast content") on the live DVB broadcast. The DVB-GEM standard's ability to define and execute such interactive applications and display them in various presentation layers alongside the main video is a direct antecedent.

    T->>T: Display Live DVB Content + MHP App Overlay Simultaneously
    U->>T: User Interacts with MHP Overlay
    T->>B: MHP App sends interaction data (if return channel available)

3. US9055255 + HTML5/CSS/JavaScript (Web Standards) for Over-the-Top (OTT) Streaming

Enabling Description:
A system implementing the principles of US9055255 for an Over-the-Top (OTT) streaming service on an intelligent TV leverages the ubiquitous open-source HTML5, CSS, and JavaScript web standards. The "live TV broadcast content" in this scenario is a live streaming video delivered over IP (e.g., using HLS or DASH protocols) to the intelligent TV. The "live TV application" is a web application (built with HTML5, CSS, and JavaScript, and running within a specialized web browser engine on the TV's processor) that manages interactive functions. Upon receiving user input (e.g., from a smart remote or companion app), this web application dynamically determines and renders an interactive feature (e.g., a "watch party" chat window, real-time sports score tracker, or contextual shopping links) as a transparent or semi-transparent overlay (the "second portion of the display overlapping live TV streaming content") directly on top of the live video feed. This approach utilizes widely adopted open web technologies to achieve the described functionality, making the combination obvious to anyone skilled in the art of web-based media delivery.
