Video Container Metadata for Embedded Binary Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video container formats lack the ability to effectively encapsulate and provide access to auxiliary data and metadata during playback, particularly for multimedia presentations, where only full artifacts like slide decks are extracted, and detailed metadata for embedded binary data is not defined, limiting user interaction and content accessibility.
Innovation Solution
A method that identifies areas of interest in video recordings and associated auxiliary items, generates metadata describing these areas, and encapsulates the video container with the auxiliary data and metadata, allowing for selective access to relevant portions during playback, such as individual slides or source code, enhancing interactivity and content extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video container formats encapsulate auxiliary data and metadata, then content accessibility and user interaction are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent embeds auxiliary binary data and metadata directly within the video container file structure, creating a nested organization where auxiliary items are contained within the main video file. This allows the container to hold multiple data types (video streams, audio streams, subtitles, chapter information, and auxiliary binary data) in a hierarchical manner, improving content accessibility while maintaining a unified file structure.
Solution Approach 2:
The patent divides auxiliary data into specific portions associated with areas of interest in the video content. Metadata describes these portions, enabling selective access to relevant content during playback. This segmentation allows users to access only the portions of auxiliary data they need, rather than requiring access to entire datasets, thus improving versatility without proportionally increasing complexity.
2Measurement precision
If detailed metadata is generated for embedded binary data, then content extraction precision is improved, but processing time and computational resources increase
Solution Approach 1:
The patent generates metadata describing auxiliary binary data portions during the video encoding process, before playback occurs. This preliminary action pre-processes and organizes the data structure with embedded timing and positioning information, so that during playback, the system can quickly locate and access specific content portions without performing complex real-time analysis, thus improving identification accuracy while minimizing processing time during playback.
3Ease of operation
If auxiliary data portions are made accessible during playback, then user interaction is enhanced, but multiplexing overhead increases
Solution Approach 1:
The patent enables extraction of specific portions of auxiliary binary data during playback based on metadata descriptions. Instead of requiring the entire auxiliary dataset to be loaded and processed, the system can extract only the relevant portions associated with current video content areas of interest. This reduces multiplexing overhead during playback while maintaining enhanced user interaction capabilities.
Data Source
AI summary
Video containers are expanded to encapsulate auxiliary data and metadata linking video content with relevant portions of auxiliary data for download during playback of particular video content. Auxiliary data is parsed into areas of interest and associated with the video content including the same areas of interest. During playback a viewer is provided access to relevant portions of the auxiliary data according to the encapsulated metadata describing the relevant portions.
