Content-Aware Metadata Embedding for Interactive Video Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video and multimedia rendering technologies lack effective integration of content-aware metadata, which limits interactive features and user engagement, as they fail to maintain tight coupling between metadata and video content during playback and user interactions.
Innovation Solution
Embedding content-aware metadata tightly within the video bitstream during encoding and decoding, using techniques like machine vision and automated processes, to enable synchronized rendering and user-interactivity features, such as region-of-interest identification and dynamic multimedia element insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content-aware metadata is embedded tightly within the video bitstream during encoding and decoding, then interactive features and user engagement are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies preliminary action by embedding content-aware metadata during the video encoding phase itself, rather than adding it later during playback. The encoder analyzes video content and inserts metadata markers, scene change information, and object identifiers directly into the bitstream as it is being encoded. This pre-preparation of interactive elements eliminates the need for complex real-time analysis during playback, reducing processing requirements while maintaining rich interactive capabilities.
Solution Approach 2:
The patent uses an intermediary approach by introducing a standardized metadata format that acts as a bridge between the video content and interactive features. This metadata structure includes standardized fields for scene changes, objects, and regions of interest that can be processed by various playback devices without requiring complex custom implementations. The standardized intermediary format simplifies device complexity while enabling versatile interactive features.
2Adaptability or versatility
If machine vision and automated processes are used to embed content-aware metadata, then user engagement and dynamic rendering are improved, but manufacturing complexity and processing overhead increase
Solution Approach 1:
The patent applies self-service by enabling the video encoding system to automatically perform content analysis and metadata generation without requiring external machine vision systems or separate automated processes. The encoder itself contains the capability to analyze video content, identify scenes, objects, and regions of interest, and embed the corresponding metadata. This self-contained approach reduces manufacturing complexity by eliminating the need for additional external systems while maintaining high user engagement through rich interactive features.
3Reliability
If metadata is tightly coupled with video content during playback, then synchronization and interactive rendering are improved, but processing load and playback performance requirements increase
Solution Approach 1:
The patent ensures reliable synchronization by performing all metadata analysis and coupling operations during the encoding phase, before playback begins. Scene changes, objects, and interactive elements are pre-identified and their metadata is embedded with precise timing information in the video bitstream. During playback, the system simply reads and processes this pre-prepared metadata, which maintains perfect synchronization with the video content while requiring minimal processing load and energy consumption.
Data Source
AI summary
An interactive video/multimedia application (IVM application) may specify one or more media assets for playback. The IVM application may define the rendering, composition, and interactivity of one or more the assets, such as video. Video multimedia application data (IVMA data may) be used to define the behavior of the IVM application. The IVMA data may be embodied as a standalone file in a text or binary, compressed format. Alternatively, the IVMA data may be embedded within other media content. A video asset used in the IVM application may include embedded, content-aware metadata that is tightly coupled to the asset. The IVM application may reference the content-aware metadata embedded within the asset to define the rendering and composition of application display elements and user-interactivity features. The interactive video/multimedia application (defined by the video and multimedia application data) may be presented to a viewer in a player application.
