Scene Description Triggers for Interactive MPEG Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing MPEG-I Scene Description lacks definitions for interactive processing of media, making it difficult to interactively process MPEG media.
Innovation Solution
An information processing apparatus and method that enables interactive media playback by specifying execution conditions and processing contents in a scene description, allowing interactive media to be played when execution conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MPEG-I Scene Description uses only startTime and autoPlay definitions for MPEG media, then the scene description structure remains simple, but interactive processing of media becomes difficult
Solution Approach 1:
The patent segments the media playback control into distinct components: execution conditions (triggers), processing contents (actions), and media identification. This segmentation allows interactive processing capabilities to be added without overwhelming complexity, as each component can be independently defined and managed within the scene description.
Solution Approach 2:
The patent introduces dynamic execution conditions and processing contents that allow media playback to respond to changing states and user interactions. The scene description transitions from static startTime/autoPlay definitions to dynamic conditional playback control, enabling adaptability while maintaining a structured framework through the conditional logic system.
2Adaptability or versatility
If the scene description adds execution conditions and processing contents for interactive play, then media interactivity is enhanced, but the complexity of the scene description increases
Solution Approach 1:
The patent creates a universal framework where execution conditions and processing contents can be applied to any MPEG media within the scene description. This multi-functional approach allows the same conditional playback mechanism to handle various media types and interaction scenarios, enhancing interactivity without proportionally increasing complexity for each specific case.
Solution Approach 2:
The patent introduces an intermediary layer of execution conditions and processing contents that mediates between the scene description structure and media playback. This intermediary framework provides a standardized interface for defining interactive behavior, allowing complex interactivity to be managed through a consistent structural pattern rather than ad-hoc implementations.

AI summary
The present disclosure relates to information processing apparatus and method that enable media to be interactively processed by a scene description. A scene description in which a description to specify that interactive media are to be interactively played and a description to specify an execution condition and processing contents of the interactive play are present is provided. Then, in a case where an execution condition of interactive play specified in a scene description has been met, interactive media specified to be interactively played in the scene description are interactively played in accordance with processing contents of the interactive play specified in the scene description. The present disclosure can be applied to an information processing apparatus, an information processing method, or the like.
