HEIF File Structure for Slideshow Audio Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in generating and playing back media files that seamlessly integrate multiple images with audio, particularly in formats like HEIF, where efficient storage and playback of slideshow content with synchronized audio are not adequately addressed.
Innovation Solution
A media file generation apparatus that creates a HEIF file with a data area for image data and a metadata area for storing information about image and audio data, including location information, allowing for the generation and playback of slideshows with audio by determining and storing image and audio data in a single file, using specific metadata processing to associate and group image and audio data effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple images and audio data are stored separately in different files, then each file can be managed independently, but the integration and synchronization of slideshow content with audio becomes complex and inefficient
Solution Approach 1:
The patent combines multiple images and audio data into a single HEIF file by creating a slideshow group that references multiple image items and associates them with audio tracks. The metadata processing means generates a unified structure where all media elements are interconnected through group identifiers and location information, eliminating the need for separate file management while maintaining synchronization capabilities.
2Adaptability or versatility
If all image data and audio data are stored in a single media file, then portability and integration are improved, but the file structure and metadata processing become more complex
Solution Approach 1:
The patent segments the HEIF file into distinct functional areas: a data area containing multiple image items with unique identifiers, and a metadata area containing slideshow group information that references these items. The metadata is further segmented into group headers, entity lists, and location information, allowing complex functionality to be organized into manageable, standardized components that simplify processing.
Solution Approach 2:
The patent implements a nested structure where slideshow groups contain entities that reference image items and audio tracks, which themselves contain nested metadata and location information. This hierarchical nesting allows the file to organize complex relationships between multiple media elements while maintaining a clear structural hierarchy that simplifies parsing and processing.
3Manufacturing precision
If location information for multiple image and audio data is stored in metadata, then data retrieval and synchronization are improved, but metadata processing complexity increases
Solution Approach 1:
The patent implements self-referential metadata structures where each image item and audio track contains inherent identification information that automatically links to corresponding location data. The slideshow group metadata uses entity identifiers that directly reference items within the same file, enabling automated retrieval and synchronization without requiring complex external mapping or manual configuration.
Data Source
AI summary
A plurality of pieces of image data and audio data are determined from a data area. Information on a slideshow group associated with a plurality of pieces of identification information identifying the respective pieces of image data and identification information identifying the audio data, and location information indicating locations, in the data area, of the plurality of pieces of image data and the audio data are stored in a metadata area. The metadata, the plurality of pieces of image data, and the audio data are stored in a single media file.
