Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing eMBMS systems lack the ability for user equipment nodes to associate interactivity media with specific linear TV channels or video clips and to determine the appropriate timing for presenting interactivity media to users, limiting the provision of enhanced interactivity services in applications like Mobile TV.

Innovation Solution

The introduction of an interactivity description fragment that includes command signals for controlling the presentation of interactivity media, allowing user equipment nodes to reference and present interactivity media files based on specific linear TV channels or video clips and time-sensitive or content-sensitive presentation windows, enhancing the data model to include an Interactivity Element within the User Service Description.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If interactivity media is delivered to user equipment nodes, then interactivity services can be provided, but the user equipment nodes cannot associate the media with specific linear TV channels or video clips

Engineering Contradiction:

Improveability to associate interactivity media with specific contentVSAvoidloss of association information between media and content

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces an interactivity description fragment as an intermediary element that carries association information between interactivity media and specific linear TV channels or video clips. This fragment includes command signals that enable user equipment nodes to properly associate and present the media in context with the relevant content

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the interactivity service delivery by separating the interactivity media file from its control and association information. The interactivity description fragment is delivered as a distinct entity containing command signals, while the media file itself is delivered separately, allowing independent processing and association

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If interactivity media is delivered to user equipment nodes, then interactivity services can be provided, but the user equipment nodes cannot determine the appropriate timing for presenting the media

Engineering Contradiction:

Improveability to present media at appropriate timesVSAvoidloss of timing information for media presentation

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by including timing control information in advance within the interactivity description fragment. The command signals contain instructions about when the interactivity media should be presented, allowing user equipment nodes to prepare and present the media at the appropriate times without losing timing information

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the data model is extended to include interactivity elements, then enhanced interactivity services can be provided, but the complexity of the data model increases

Engineering Contradiction:

Improveenhanced interactivity service capabilityVSAvoidcomplexity of data model

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements nesting by integrating the interactivity description fragment within the existing User Service Description data model structure. The interactivity elements are nested as additional components within the established MBMS data model framework, allowing enhanced functionality while maintaining compatibility with existing structures

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A method in a user equipment node for providing interactive services to a user of the user equipment node, comprising the steps of receiving an interactivity media file comprising information which is to be presented to the user. An interactivity description fragment is also received, the interactivity description fragment comprising one or more command signals for controlling how the information received in the interactivity media file is to be presented to the user. The information received in the interactivity media file is presented to the user using the one or more command signals received in the interactivity description fragment.
